Hi there...

Often I install PVE on top of kvm/libvirt using virt-manager, in order to
create a lab test on my laptop.
Usually I never been concern about nothing inside PVE after install it in
virt-manager, but after upgrade to 6.2-4, the VM won't started, and get
this error:

kvm: error: failed to set MSR 0xe1 to 0x0
kvm: /build/pve-qemu/pve-qemu-kvm-5.0.0/target/i386/kvm.c:2695:
kvm_buf_set_msrs: Assertion `ret == cpu->kvm_msr_buf->nmsrs' failed.
TASK ERROR: start failed: QEMU exited with code 1

I have fix it with:
echo Y > /sys/module/kvm/parameters/ignore_msrs

But I have no clue why this happened!
