:SELinux is preventing /usr/bin/qemu-kvm from 'getattr' accesses on the filesystem /.
:
:*****  Plugin catchall (100. confidence) suggests  ***************************
:
:If you believe that qemu-kvm should be allowed getattr access on the  filesystem by default.
:Then you should report this as a bug.
:You can generate a local policy module to allow this access.
:Do
:allow this access for now by executing:
:# grep qemu-kvm /var/log/audit/audit.log | audit2allow -M mypol
:# semodule -i mypol.pp

This is from a machine running as an oVirt 3.1 host.

Comment 2 Daniel Walsh 2012-08-01 19:10:22 UTC
Are you using nfs with your virtualization?

Comment 3 Jason Brooks 2012-08-01 21:13:04 UTC
(In reply to comment #2)
> Are you using nfs with your virtualization?

Yes, I am.

Comment 4 Daniel Walsh 2012-08-02 20:55:53 UTC
Turn on the virt_use_nfs boolean if you have not already.

Miroslav Just checked a fix into rawhide for this.
