Sometimes you have a DUH moment.
I just had was one: I upgraded VMware Workstation to 8.0.2 a couple of days ago.
Today one the less frequently used development virtual machines would not see the SQL Server 2000 alias it could find before.
Reasons:
- the ALIAS cannot be found through DHCP, so it was in the HOSTS table on the development virtual machine.
- the subnet of vmnet1 and vmnet8 got changed because the VMware update actually is performed ad a complete reinstall.
I blogged about the SQL Server 2000 alias last week, but in fact the work had been more than 2 months ago, so it took me a while to add up reasons 1 and 2 and find out the answer was in fact 3:
Reset the VMware vmnet1 and vmnet8 to the subnets they were before, and everything works fine and all is dandy again.

Somehow, I have the impression that not all VMware View Client network admins fully read and understand the “PCoIP Protocol Virtual Desktop Network Design Checklist“
That checklist is important, as it is easy to get things wrong and dissatisfy your users without reason (heck, they get worse than mediocre RDP performance experience, so you could’ve saved you the work of PCoIP in the first place).
So please do read the “PCoIP Protocol Virtual Desktop Network Design Checklist“.
It starts with
The PCoIP protocol provides a real-time delivery of a rich user desktop experience in virtual desktop and remote workstation environments.
To ensure a responsive desktop, the PCoIP protocol must be deployed across a properly architected virtual desktop network infrastructure that meets bandwidth, QoS, latency, jitter, and packet loss requirements.
CheckPoint VPN sometimes can be a dork combined with PCoIP. and at least make sure UDP works well over your VPN.

Lets start post 800 by mentioning it took quite a bit of time to solve the connection problem to VDI. I hope it will help others, and if I ever run into this again myself: now I know where to look
Some clients make heavy use of VMware VDI (Virtual Desktop Infrastructure) which moves the desktop into the VMs in the data center.
A while ago I spent most of the day tracking down a “Connect Desktop Failed” error with VMware View Client running on a Windows 7 x64 workstation to connect to a VDI VM. It would connect to the VDI server, authenticate, start the Desktop, but could not connect to the Desktop.
The amazing thing is that the VMware view client worked fine on an XP VM workstation (with and without SNX) XP physical machine with SNX, and another Windows 7 x64 VM workstation (also with and without SNX) and Windows 7 x64 physical machine with SNX.
Clearly something was wrong with this particular Windows 7 x64 workstation that is host of most of my development VMs so I didn’t want to do a re-install.
I tried many obvious things on the Windows 7 x64 workstation:
- reboot
- disable firewall
(that would have indicated some of the ports required by VMware view were not open: in practice not all ports mentioned in the list are used)
- uninstall software from various vendors that might interfere with network activity
- disabled virus scanner
- step down from VMware View Manager 5 client to VMware View Manager 4.6 client
- circumvented SNX (CheckPoint SSL VPN extender) making sure I was on the same WAN and later LAN of the VDI
- verified twice I had indeed Windows 7 SP1 applied
- laughed about the SSE support required by VMware view client
Since the “Connect desktop failed” does not return many English search results, I started browsing the Russian ones. Read the rest of this entry »

Note that Sharing a Mac folder through VMware Fusion to a Windows VM works, but is:
- not fast
- eats a lot of Mac resources
(it would get the fan of my MacBook Air running like mad when copying about 1Gigabyte of files – about 20-thousand files total; a robocopy /mir sync when nothing is changes takes a whopping 5 minutes)
This is how you do it:
To configure a shared folder in a Windows virtual machine:
- Launch VMware Fusion.
- Power on the virtual machine.
- Click Virtual Machine > Settings.
- Click Sharing.
- Select Share folders on your Mac.
- Click the + button.
- Browse to the folder on the Mac that will be shared with the virtual machine and click Add.
Shared folders can be accessed via the VMware Shared Folders shortcut on the Windows desktop or the mapped network drive Z:.

If you have reactions on the question below, please add them to the SuperUser.com thread when possible.
Every once in a while, my MacBook Air becomes unresponsive when it is sleeping and I open the lid.
It seems to only happen in these circumstances:
- the MacBook air got into sleep modus because of closing the lid
- VMware Fusion 4 (4.0.2 build 491587) is running full screen
- The guest OS has a blank screen screen saver
When opening the lid, the backlight goes on, but the MacBook Air does not react on any key-combinations I tried.
I tried these, but to no avail:
- press the Touchpad
- press Control + Command
- press Control + Command + Enter
- press Command + Tab
The only thing that works is to press the Power button for 5+ seconds (forcing a hard power off) then reboot.
Two questions:
- For anyone having seen similar bahviour: what circumstances did you have?
- Any solution to this apart from first suspending the guest VM?

This might not be strictly legal, but it is supposed to be possible to run the retail OS X Lion 10.7 under VMware Workstation 8 (or VMware Fusion 4) and VMware Workstation 7.1.4 (or VMware Player 3.1.4) on a regular PC (if that PC Supports VT) running Windows 7 x64.
Since Apple MacBook still don’t come with a TrackPoint (and having suffered from RSI, that is about the only pointing device I can use) there are only two options for me:
- Go the route described above
- Use an external USB TrackPoint keyboard with a Mac
(traveling with a huge external USB keyboard, I’d look like my long time friend Mark Miller from DevExpress, who also suffered from RSI)

The RDP to VMware host running an XP guest: Invisible Mouse Cursor on Text Editors problem is not limited to RDP-ing into the VMware host, but also happens on some hosts themselves (including my ThinkPad W701 running Windows 7 x64).
This VMware Communities: Invisible Mouse Cursor on Text Editors … thread (that has a different host configuration: Vista) comes up with 2 different solutions that both work:
- Make your Windows XP mouse scheme the “Windows Black (system scheme)”
- Put the Windowx XP video hardware acceleration one position below maximum.
Since less hardware acceleration also means far less performance, I’ve opted for the first solution.

If you use NTP for syncing your time, then choose pool.ntp.org as your time server:
The pool.ntp.org project is a big virtual cluster of timeservers providing reliable easy to use NTP service for millions of clients.
I use it for instance to synchronize the time on my ESXi servers.
Note: when you run Windows VMs as ESXi guests; let ESXi time-sync them through the VMware tools, and disable Windows’ own time syncing. I didn’t disable it, and my Windows VMs were consistently off by over 30 minutes.

James Clements explains how to resize your VMware ESXi/ESX/vSphere disks.
You can resize the disks live when using ESXi/ESX/vShere 4 and up.
When using Windows Vista or 2008 and up, you don’t need special tools for resizing the partitions on those disks: the built-in disk manager can do it.
When using Windows 2003 Server, Windows XP or less, then you need the EXTPART tool from Dell as explained by GeekSeat:
All you need to do now is provision the extra space to the VM, then run the tool at the command line and follow the wizard:
C:\>extpart.exe
ExtPart - Utility to extend basic disks (Build 1.0.4)
(c) Dell Computer Corporation 2003
.
Volume to extend (drive letter or mount point): c:
Current volume size : 66285 MB (69504860160 bytes)
Current partition size : 76285 MB (79990815744 bytes)
Size to expand the volume (MB): 76285
that’s it – job done . . zero downtime (watch out of course . . this works differently if you have a clustered disk to extend – see: http://geekseat.wordpress.com/2011/01/25/replacing-clustered-storage-for-a-sql-cluster-emc-ce-ms-clustering/ )
Note the “Size to expand” is actually the number of MB you are adding to the volume as Redelijkheid explains.
There is no need to reboot after expanding using ExtPart.
Edit: 20111222; you can download ExtPart through the DELL web-site; there are also direct http downloads of the EXE and README, and direct ftp downloads for the EXE and README.
If you don’t trust ExtPart, there is always the GParted way as explained by BleepingComputer.com.

When you install VMware Server 2.0 on Windows Server 2008, Internet Explorer will give you a warning that it cannot load the local VMware Server console web-site at https://servername:8333.
The reason is that the security certificate is self-signed by the local machine, not by a trusted CA.
Internet Explorer does not allow you to add that CA, but you can from within Windows Explorer.
The Removing the VMWare Server SSL Certificate Trust Warning article explains how.
Note that on x64 Windows Server 2008 systems, the VMware Server certificate by default is in the C:\Program Files (x86)\VMware\VMware Server\SSL directory.
Finally, you will need to add https://servername:8333 to the trusted sites in Internet Explorer.

With the gaining popularity of Desktop systems with multi-core processors, it becomes interesting to use multi-core CPU guests in VMware workstation.
Right now, Intel Core i3 through i7 processors can provide from 2 to 6 cores, some cores even supporting hyper-threading and providing 12 virtual cores using a single physical processor.
Does it make sense now to run all your VM guests with multiple virtual cores / vCPUs?
On the VMware forums and knowledge base, there are many threads and articles with information on vCPUs.
The consensus is that VMware workstation can take longer to schedule a synchronized set of cores for a VM than VMware ESX(i) has, and the host OS needs CPU cycles too.
The reason is that VMware workstation needs the underlying host Operating System for that, whereas ESX(i) has it’s own kernel.
In the VMware workstation 7 beta, under some circumstances, adding more vCPUs actuall made the guest run slower (this has been fixed).
You need to be careful when vCPUs in the guest compete with pCPUs in the host; it can lead to frequent freezes in the guest.
The rule of the thumb is that you should not use more than 50% of the host pCPU cores as guest vCPUs.
So the best is to start with one (1) vCPU, and only crank it up when needed.
Take into account however that for Windows XP you will need to change the HAL to support multiple CPUs, which can be a pain.
In some cases it can pay off big to increase the number of vCPUs, especially when they are actually used.
Another thing you need to be aware of is that modern CPUs van vary their clock speed, now even depending on the number of cores used. In the past this had influences on timekeeping, but not so any more with modern Core i# processors.
Finally, with the increase of hard-disk space, people use snapshots more often. This can dramatically decrease the performance, as the number of open files per VM increases.
I hope this helps you choosing the number of vCPUs in your guest.
–jeroen
Note: Both VMware ESXi and VMware Workstation 7.1+ can even support vCPU with multiple cores to help cope with guest OS CPU licensing limitations: set the cpuid.coresPerSocket property in your vmx for that.

Searching how to increase your Windows XP NTFS partitions of Virtual Machines running under VMware Workstation 7 gets you a truckload of links trying to get you to do all sorts of command-line like vmware-vdiskmanager and such.
That was indeed the case up till VMware Workstation 6.5, but from version 7 on, it has become much easier.
But the links with difficult steps keep appearing at the top of the search queries.
Hence this blog entry: increasing the NTFS partition size in a Windows VM is easy!
The increase is a two step process:
- In VMware Workstation, increase the size of the physical disk
- Increase the NTFS partion on that physical disk
Step 1 has become much easier since VMware Workstation version 7, you can do it from within VMware Workstation now.
Dinesh describes this small process very well in his Expand Disk in VMware Workstation 7 blog post. Read the rest of this entry »

After upgrading VMware workstation, I noticed when making backups of my VMs that they contained lots of files in the guestappscache subdirectory that have names containing GUIDs.
I’m always wary for sudden seemingly random files being created.
It might be just some kind of virus slipping through the gates targeting a specific vulnerability.
The files appear to be for Unity, and it is easy to disable Unity. (I don’t use Unity: I use VMs to separate work and keep the clutter away from my host machine’s desktop <g>).

VMware ESXi has SSH disabled by default.
In ESX / ESXi 3 and 3.5, it took a while for people to recognize the ‘unsupported’ trick and enable SSH.
In ESXi 4.0, /sbin/services.sh was fixed, so SSH was easier to enable (note: only delete the # in front of the first ssh).
Since ESXi version 4.1, SSH is called “Remote Tech Support (SSH)”, and it very easy to enable from the console.
Thomas Maurer described how easy it is to activate SSH in ESXi 4.1. He provides clear screen shots, whereas the VMware knowledge base article just lists the textual steps.
But contrary to ESX/ESXi 3.5 and lower, and *nix habits, enabling SSH on ESXi 4.x will enable this for the root user.
This has to do with the switch between ESX/ESXi 3.5 and 4.0 from to the dropbear ssh daemon (in the /sbin/dropbearmulti binary).
Dropbear is a very lightweight implementation of the SSH 2 protocol; ideal for ESXi which – as a hypervisor – needs to have a really low footprint.
In addition to the dropbear change, SSH is disabled for non-root users (which has nothing to do with dropbear, see below).
This post is about how to fix not only the SSH (as above) but also how to allow specific users to use SSH. Read the rest of this entry »

Note that what you can do through the SDK (and vMA and its’ virtual appliance or that matter) is limited by what your ESX / ESXi license allows.
The VMware KB has more information on this: you will need at least a vSphere Essentials license for your ESXi box to use it..
If you have a free ESXi license, you will often get messages like these:

Fault string: fault.RestrictedVersion.summary

I know that ESXi 4.1 requires VT (the Intel support for hardware assisted virtualization) to be enabled to run x64 VMs.
This is the warning that you get when starting an x64 VM, and you don’t have VT enabled:

[Main Instruction]
Virtual Machine Message
msg.cpuid.noLongmodeQuestionFmt: This virtual machine is configured for 64-bit guest
operating systems. However, 64-bit operation is not possible.
This host is VT-capable, but VT is disabled.
VT might be disabled if it has been disabled in the BIOS settings or the host has not been
power-cycled since changing this setting.
(1) Verify that the BIOS settings enable VT and disable ‘trusted execution.’
(2) Power-cycle the host if either of these BIOS settings have been changed.
(3) Power-cycle the host if you have not done so since installing VMware ESX.
(4) Update the hosts’s BIOS to the latest version.
For more detailed information, see http://vmware.com/info?id=152

Sometimes when you add a new user to your ESXi 4.x installation, you get this error message (click for the full size picture):
Create User: User name or password has an invalid format
Until now, only a few russian pages described the cause:
Without console login (or SSH - see my blog tomorrow), you cannot see the obvious reason for this message:
Your password does not adhere to the ESXi 4.x password policy, which is more strict than the ESX/ESXi 3.x policy.
