VM doesn't start

[Nico69]

Hello
I am new in the Proxmox community. I am trying to run a VM but it won't start. This is the only output of the VM:

kvm: warning: TCG doesn't support requested feature: CPUID.80000007H:EDX.invtsc [bit 8]
kvm: CPU model 'host' requires KVM or HVF
TASK ERROR: start failed: QEMU exited with code 1

Can someone please help me.
Thanks

Hi
This means some CPU flags of your host system are not supported by the new qemu version.
You can change the cpu type of your VM to the more conservative "kvm64" type, and see its fix your problem.

I have already tried this and it doesn’t work.

Hi,
please share the VM configuration qm config <ID> and output of pveversion -v. From the error message, it seems you are using TCG CPU emulation, i.e. the kvm flag in the configuration is turned off ([VM] > Options > KVM hardware virtualization in the UI), but are using a CPU type that uses a flag that is not supported by TCG yet.
