description |
Using wily (libvirt 1.2.16-2ubuntu11.15.10.3) in a AMD FX-8350 nested KVM doesn't work, unless in the definition of the vm the cpu is configured with mode='host-passthrough', for other CPUs the manifestation could be different.
ProblemType: Bug

Package: libvirt-bin 1.2.16-2ubuntu11.15.10.3
ProcVersionSignature: Ubuntu 4.2.0-34.39-generic 4.2.8-ckt4
Uname: Linux 4.2.0-34-generic x86_64
NonfreeKernelModules: nvidia
ApportVersion: 2.19.1-0ubuntu5
Architecture: amd64
Date: Wed Mar 23 11:20:11 2016
InstallationDate: Installed on 2014-12-06 (472 days ago)
InstallationMedia: Ubuntu 14.10 "Utopic Unicorn" - Release amd64 (20141022.1)
SourcePackage: libvirt

Using wily (libvirt 1.2.16-2ubuntu11.15.10.3) in a AMD FX-8350 nested KVM doesn't work, unless in the definition of the vm the cpu is configured with mode='host-passthrough', for other CPUs the manifestation could be different.
Steps to reproduce:
L0: wily
$ uvt-kvm create --memory 2048 --cpu 2 vm-L1 release=wily arch=amd64 # the L1 guest can be trusty too, it doesn't really matter
$ uvt-kvm ssh --insecure vm-L1
(vm-L1)$ sudo apt-get install cpu-checker
(vm-L1)$ sudo kvm-ok
INFO: Your CPU does not support KVM extensions
KVM acceleration can NOT be used
(vm-L1)$ sudo modprobe kvm-amd
modprobe: ERROR: could not insert 'kvm_amd': Operation not supported
(vm-L1)$ dmesg | grep kvm | tail -n1
[45890.075592] kvm: no hardware support
Expected Result:
kvm-ok says that virtualization is supported
Workaround:
1) Shutdown the VM (vm-L1)
2) In the kvm host edit vm-L1 definition (sudo virsh edit vm-L1) and change the cpu definition to:
<cpu mode='host-passthrough'></cpu>
3) power on the VM
