[Bug 1057024] Re: kvm kernel module always loaded, without setting /dev/kvm permissions

[Serge Hallyn]

Thanks for bringing the laptop.

We took a look.  After installing qemu-kvm and libvirt (and virt-
manager) /dev/kvm has the right permissions and ownership.  User ubuntu
is able to run kvm.  However when doing

    sudo -u libvirt-qemu strace -f -o/tmp/outout kvm -vnc :1

you see that when it tries to open /dev/kvm it gets -EACCESS.

Doing 'rmmod kvm_intel kvm; modprobe kvm_intel' results in /dev/kvm
being created with the exact same owner/perms as before,  but now
libvirt-qemu is able to open the device.

I did not think to look at the acls.

** Changed in: qemu-kvm (Ubuntu)
