Virt-manager => Disk => Change the Disk bus to IDE
  • Boot the guest and uninstall the SUSE Block Driver within the VM
Device Manager => "Show hidden devices in the menu"=> Suse Block Driver for Windows => Uninstall
  • Now change the driver back to virtio and the guest should be able to boot.

Disabling SUSE Block Driver update in existing Windows VMs

  • Find the update options
Control Panel => System and Security => Windows Update => Select the link for optional updates available.
  • Uncheck Storage Controller => SUSE Block Driver for Windows.

Hide the Update

  • Hide it by right-clicking on the line and selecting “Hide Update” from the pop-up menu
  • This will hide the SUSE Block Driver for Windows in the future Windows updates

Root Cause

  • The latest Windows update offers SUSE Block Driver which overwrites existing Red Hat virtio driver. . The SUSE driver which installed is incompatible with the KVM based hypervisors which causes this BSOD.
