Update:

So after some digging, it seems this has been reported as an issue many times.

As a workaround, I added the an entry to the kvm.conf in modprobe.d directory 
of ignore_msrs=1 and that allowed Blue Iris to boot.

Would be nice to have an actual fix for this instead of a workaround. Would 
really like to know why kvm is thing that ia32_debugctl is not a valid cpu 
option.

Subject: Win Server 2k19 and BlueIris

So I have been running Windows Server 2019 on Proxmox VE with Blue Iris NVR. 
Tried to migrate the qcow disk over to oVirt, and like other Win2k19 servers, 
they all give a BSOD with a KMODE error.

Last night I installed 2k19 from scratch, installed the latest drivers I could 
find, oVirt-toolsSetup-4.3-3.el7, and proceeded to load up Blue Iris. As soon 
as I go to start Blue Iris, the VM hangs, then gives a BSOD with SYSTEM SERVICE 
EXCEPTION.

Looking at the debug log on the ovirt node the VM is running, there one entry 
that gets created on each crash with, "kvm [4723]: vcpu1 kvm_set_msr_common: 
MSR_IA32_DEBUGCTLMSR 0x1, nop".

Running on oVirt node 4.3.8, cluster cpu is Intel Westmere IBRS SSBD Family, 
pc-i440fx-rhel7.6.0, and the physical cpu is 24x Intel(R) Xeon(R) CPU X5670 @ 
2.93GHz.


Any ideas?
