Red Hat Bugzilla – Bug 736071
kvm modules are not loaded in fedora16 - nested virtualisation approach
Last modified: 2012-05-04 09:15:01 EDT
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
[user@localhost ~]$ rpm -qa | grep kvm
[user@localhost ~]$ rpm -qa | grep qemu
[user@localhost ~]$ rpm -qa | kernel
bash: kernel: command not found...
[user@localhost ~]$ rpm -qa | grep kernel
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.
not working nested virtualisation with kvm
nested virtualisation should work with kvm
give me some time to complete this report here.
Have forgotten to set the severity to medium.

the logs above are from the fedora 15 host.

there was also a network error in the fedora16 guest
That it is from my side.

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.
