Windows 10 1511 update broke the Hyper-V networking – Fix network connection issues

Posted by jpluimers on 2016/04/11

After updating a Windows 8.1 machine that had Hyper-V running, none of the VMs could access any networking: Windows 10 build 1511 completely broke the vSwitch infrastructure.

This is what I had to do:

  1. Reinstall network devices using netcfg –d command (Source: Fix network connection issues – Windows Help)
  2. Reboot host
  3. Create a new vSwitch in Hyper-V (as the old one was gone)
  4. Remove the network adapters of the VMs (they were in a limbo state)
  5. Add new network adapters to the VMs connecting them to the correct vSwitch.

This was the umpteenth time Hyper-V let me down, so in the future I’m back to VMware or Virtual Box.

Windows 10 also broke Everything Search Engine and UBCD4Win. I could not get UBCD4Win to work again, but a reinstall of Everything made it to work again.

And Windows 10 moved a lot of things away from the Control Panel, which means that things that basically worked for more than a decade are now gone. For instance, Windows updates now must be run with a shortcut like this:

%LocalAppData%\Packages\windows.immersivecontrolpanel_cw5n1h2txyewy\LocalState\Indexed\Settings\nl-NL\AAA_SystemSettings_MusUpdate_UpdateActionButton.settingcontent-ms

Note that’s for a DUTCH system. For a US-English system of course the shortcut is different:

%LocalAppData%\Packages\windows.immersivecontrolpanel_cw5n1h2txyewy\LocalState\Indexed\Settings\en-US\AAA_SystemSettings_MusUpdate_UpdateActionButton.settingcontent-ms

This feels like “1998 wants its VBA translated languages back”.

Of course I could get around this by building a table translatingto a text language code from the numeric language code* from the below command, but that’s not the point: Windows 10 makes life harder.

reg query “hklm\system\controlset001\control\nls\language” /v Installlanguage
returns codes like 0407, 0409, 040D, 0413, etc.

*: Heck if Microsoft cannot even update their 2002 Table of Language Culture Names, Codes, and ISO Values Method [C++] and has trouble keeping the various .NET version pages updated**, how could I?

**: these are the only .NET versions the table is documented

SATA controller links for ZFS and ESXi

Posted by jpluimers on 2016/04/08

Some useful links:

M1015 is still used a lot, but there are many choices for SATA/SAS HBAs that are compatible with ESXi and ZFS.

SATA passthrough for many things seem to have stopped with ESXi 5.5 (5.1 and below should work). Some links related to that:

IDE and USB passthrough of CD/DVD devices seem to be fine though:

OEM adapters:

There are many SFF-8088 to SFF-8087 adapters.

VirtualBox: Clone VM without Re-activation of Windows 7 (via: Danny Thorpe – Google+)

Posted by jpluimers on 2016/04/04

This week I needed the trick below, so I was glad that a long time ago, Danny Thorpe Shared publicly on G+:

[Wayback/Archive] VirtualBox: Clone VM without Re-activation of Windows

Follow these steps to clone a VirtualBox VM in a manner so that the Windows 7 Activation in the guest doesn’t have to be re-activated in the clone.

Tools that Isotopp installed on his Mac…

Posted by jpluimers on 2016/04/01

IRC so: »i> Isotopp: Ich habe jetzt nen Mac als Arbeitsplatzrechner… Was will man als UNIX Hacker zuerst an Tools installieren?«

Source: IRC so: »i> Isotopp: Ich habe jetzt nen Mac als Arbeitsplatzrechner… Was will… by Kristian Köhntopp.

Since G+ is very bad at searching, I created this summary of the tools; read the full G+ post (Google Translate is quite OK), including comments on why.

Edit: 20160402 – I’m posting regular updates based on the comments for that G+ post. I’ve changed or added German iTunes store links to US-English ones.

Solving VMware Fusion 6 and Windows 7 VM performance issues | Shogan.tech

Posted by jpluimers on 2016/03/21

Add these entries to your .vmx file:

MemTrimRate = "0"
sched.mem.pshare.enable = "FALSE"
prefvmx.useRecommendedLockedMemSize = "TRUE"

Works in VMware Fusion 5, 6, and 7. Probably 8 too.

Getting the ESXi version from the console

Posted by jpluimers on 2016/03/10

Since ESXi is based on busybox, it is using ash a variation of sh (the classic bourne shell) called Almquist shell and most nxes use some form of bash a lot of things won’t work.

For instance, doesn’t support sh –version.

Luckily there are uname -mrs and (more elaborate) vmware -vl to get the version.

Note there is support busybox aliases so alias dir=”ls -laF” works, and you can define aliases for the version information too.

ZFS, SuperMicro, ESXi passthrough, CrashPlan and other links

Posted by jpluimers on 2016/01/11

Some great blog entries to read:

And:

Finally:

All of the above are somehow related to the Superserver SYS-5028D-TNT4.

When looking at some pictures from the above posts, then an M1015 HBA should be perfect for ZFS (lots of results for ESXi M1015 HBA PCI VMDirectPath IO pass through, and they still seem to be the way to go for ZFS).

There might be a need for extra cooling; for some ideas: Cooling for m1015 Raid Card – [H]ard|Forum

Below are other ServerRAID OEM possibilities supporting 8 internal devices (chipset in parentheses) via:

12 Gbps adapters:

  • EUR ~180: ServeRAID N2215 (SAS3008)
    • EUR ~300: LSI 9300-8i (LSI00344)
  • EUR ~200: ServeRAID M5120 (SAS3008)
  • ServeRAID M5210e (SAS3008)

6 Gbps adapters:

3 Gbps adapters:

  • ServeRAID MR10i (SAS1078)
  • ServeRAID BR10i (SAS1068e)
  • ServeRAID BR10il v2 (SAS1068e)

D-1541 with increased speed plus support for SR-IOV and DDR3 memory might end up in Supermicro SYS-5028D-TN4T somewhere in februari

Posted by jpluimers on 2016/01/04

I wrote about TinkerTry’s Xeon D-1540 fueled ESXi 6.0 home lab build begins LIVE! before as I think it is an amazing buy.

In the mean time, there are more some bundles of it available, even one shipping from The Netherlands:

Currently these machines (called SYS-5028D-TN4T) contain a Xeon D-1540 processor and use the X10SDV-TLN4F that also lists the Xeon D-1541 processor which will likekly be available on that board starting from about February. The Xeon D-1541 processor which adds new features: is about 5% faster and adds support for both SR-IOV (which can help with virtualisation, but isn’t supported by ESXi on these processors yet), DDR3 memory and Storage Performance Development Kit support for storage acceleration: Intel Xeon D-15×1 Storage Accelerated SKUs.

You have to choose, as they use the FCBGA 1667 which – like any other BGA – are soldered. So if you need these feaures and can wait 2 more months, then go for the Xeon D-1541. Otherwise, order now.

Some articles to help you decide:

On a different topic: if you want to cool the processor better, consider re-applying cooling paste: Socket FCBGA 1667 aftermarket cooling?? | Page 2 | ServeTheHome and ServeThe.Biz Forums.

And finally two more things:

  1. There is a D-1548 too which compared to the D-1540 has the CPU speed, but adds SR-IOV and DDR3 memory support.
  2. There will be 12-core and 16-cores varieties in the Xeon-D series later this  year: Intels Server-Prozessor Xeon D-1500: 16-Kern-Version tritt 2016 gegen ARM-SoCs an | heise online.
    According to the current SuperMicro Xeon-D information these will be available in boards that seem to fit in the SYS-5028D-TN4T system:

    1. X10SDV-12C-TLN4F.
    2. X10SDV-16C+-TLN4F.

Anyway: I think with either processor, you have a great deal!

How too many vCPUs can negatively affect performance | Gabes Virtual World

Posted by jpluimers on 2016/01/03

Interesting:

Think twice before you give VMs extra vCPUs which they don’t really need. You can negatively impact the performance of your environment since the vmkernel has to try and find a time slot in which it can give all vCPUs access to the physical cores.

ESXi Embedded Host Client – VMware Labs

Posted by jpluimers on 2015/12/22

Interesting stuff to play with the next few weeks:

This version of the ESXi Embedded Host Client is written purely in HTML and JavaScript, and is served directly from your ESXi host and should perform much better than any of the existing solutions.

Thanks Paul Braren for sharing this.
