Always use SCSI for your VM guest disks – Jeroen Wiert Pluimers – Google+

Posted by jpluimers on 2020/01/20

Rephrased from [WayBackJeroen Wiert Pluimers – Google+:

If you install a virtual machine, ensure the disk controller and disks are SCSI based.

This has many advantages, including:

  • speed (usually the SCSI drivers can be paravirtualised)
  • hot addition of new disks

It holds for virtually any virtualization platform including all non-ancient (less than ~10 year old) versions of:

  • VMware (Workstation, Viewer, but I expect this also to work on vSphere, ESXI, Fusion)
  • Hyper-V
  • KVM (and therefore Proxmox)
  • VirtualBox

Based on my notes in the above link and the links below:

Note this isn’t just for Linux guests/hosts: Most guests (including Windows) can do a SCSI bus re-scan and detect new SCSI devices.

The trick here is that the guest must already have a virtual SCSI controller (adding that will require a reboot of the guest).

Then adding a new SCSI disk on that controller from any host (Windows, Mac, ESXi, vSphere) should work fine.

Is memory ballooning a thing from the past or still current?

Posted by jpluimers on 2018/02/02

I wonder with the current memory pricing and amounts of memory that host machines have: is memory ballooning a thing from the past?
