PVE 4.0 Beta2 + qemu + acpi

[Egner]

Paolo from qemu team think that it could be a (physical) cpu bug.
Is your bios and cpu microcode updated to last version ?

My server where I can hit the bug is not updated since 2010.

I using the latest BIOS but the server is still quite old. What server version do you have?

Can you send me results of :

grep -r . /sys/module/kvm*/parameters


Paolo can now reproduce it with
/sys/module/kvm_intel/parameters/unrestricted_guest = N

 

[Whatever]

Here we go
