Description melchiaros 2011-09-06 15:11:09 UTC
Description of problem:
I´ve tried to do nested virtulisation with KVM from a fedora 15 host and a fedora16 guest with a openSUSE12.1 MS5 subguest.

The problem is that the fedora16 guest does not load kvm modules.

I first attach the files and logs for the fedora 15 host and later(when I get them) for the fedora16 guest.


Version-Release number of selected component (if applicable):

from the fedora15 host:

[user@localhost ~]$ rpm -qa | grep virt-manager
virt-manager-0.8.7-4.fc15.noarch
[user@localhost ~]$ rpm -qa | grep kvm
qemu-kvm-0.14.0-7.fc15.x86_64
[user@localhost ~]$ rpm -qa | grep qemu
gpxe-roms-qemu-1.0.1-4.fc15.noarch
qemu-system-x86-0.14.0-7.fc15.x86_64
qemu-kvm-0.14.0-7.fc15.x86_64
qemu-common-0.14.0-7.fc15.x86_64
qemu-img-0.14.0-7.fc15.x86_64
[user@localhost ~]$ rpm -qa | kernel
bash: kernel: command not found...
[user@localhost ~]$ rpm -qa | grep kernel
arm-gp2x-linux-kernel-headers-2.6.12.0-5.fc15.noarch
abrt-addon-kerneloops-2.0.3-1.fc15.x86_64
kernel-debug-2.6.40.3-0.fc15.x86_64
kernel-2.6.38.6-26.rc1.fc15.x86_64
kernel-devel-2.6.40.3-0.fc15.x86_64
kernel-headers-2.6.40.3-0.fc15.x86_64
kernel-2.6.40.3-0.fc15.x86_64




How reproducible:


Steps to Reproduce:
1.use fedora 15 as host 
2.install the virtualisation meta package
3.create fedora16 guest with virt-manager
4.install the virtualisation meta package in the fedora 16 guest
5. try to install a guest(whatever- I´ve used openSUSE12.1 MS5)in the fedora16 guest(after a newstart - you know) with virt-manager and kvm
6. see the message from virt-manager that the kvm modules are not loaded.
  
Actual results:
not working nested virtualisation with kvm

Expected results:
nested virtualisation should work with kvm

Comment 9 Cole Robinson 2012-05-04 13:15:01 UTC
If installing the guest with virt-manager, you need to go to VM->CPU->Copy host cpu  to ensure that all the host CPU flags are passed to the guest.

Either way, the KVM package was merged with the qemu package, so any future issues should be filed against the 'qemu' component, or in this case 'virt-manager' or 'libvirt.
