Description of problem:
startart VM via virt-manager in this case it was kubuntu 11.10
mount read only vm drive i used this command uestmount -a /var/lib/libvirt/images/ubuntu2.img -i --ro /media/xp/
try to cd into vm and try to copy something from VM
SELinux is preventing /usr/bin/qemu-system-x86_64 from 'read' accesses on the file /var/lib/libvirt/images/ubuntu.img.

*****  Plugin catchall (100. confidence) suggests  ***************************

If you believe that qemu-system-x86_64 should be allowed read access on the ubuntu.img file 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-system-x86 /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
