Nov 23 16:45:40 pve kernel: set kvm_intel.dump_invalid_vmcs=1 to dump internal KVM state.

The error does not appear immediately. Maybe 5 seconds, maybe 10 minutes.
I don't have nested virtualization. Just a host and a virtual machine. The operating system in the virtual machine can be any: ubuntu16, windows7...
CPU - 2 x XEON E5 2695 v3.

Help me please.

Did you install the intel microcode package?
What PVE version are you running? pveversion -v

 

[Beskr_Serg]

Intel microcode package installed.
Tried both 7.0 and 7.1

 

[mira]

Could you provide a sample VM config (qm config <VMID>) for a VM that crashes?

 

[Beskr_Serg]

Tried different configurations.
Tired.
Changed the server. DELL R610 now. CPU - XEON 1 * X5650.
All virtual machines are running.

Thank you very much.
