Right now to get around the problem I returned to the official stretch
packages, and I'm using the Opteron_G1 / kvm64 / qemu64 cpu. I have no
errors in the guest machine, while on the host machine this message
appears when the guest machine is booted:
kvm [61880]: vcpu2, guest rIP: 0xffffffbb8595c2 unhandled rdmsr: 0xc0011029
this error appears during the loading of the kernel
Guest debian stretch 4.9.0-6-amd64
I tried to go back to version 4.9.0-4-amd64 and this error does not
appear because?
Should I report only this last in the kernel section?
Thank you
