[Windows 11 VM freezes after several minutes idle [ 6.10.0-rc2 ]]

iam experiencing the same issue as well. hopefully someone finds the issue or what causes the issue. 

[Unraid OS version 6.9.0-beta22 available]

for all those who are running Ryzen 3rd Gen processors and using VM's, there seems to be a bug in Qemu 5.0 where in windows enters a BSOD with an error message KERNEL_SECURITY_FAILURE.

 

Here is a link to the discussion on reddit:

The following MUST be added to the VM xml file to allow windows to successfully boot.

 

<qemu:commandline>

<qemu:arg value='-cpu'/>

<qemu:arg value='host,topoext=on,invtsc=on,hv-time,hv-relaxed,hv-vapic,hv-spinlocks=0x1fff,hv-vpindex,hv-synic,hv-stimer,hv-reset,hv-frequencies,host-cache-info=on,l3-cache=off,-amd-stibp'/>

</qemu:commandline>
