Hi folks,

Since I have moved the image file of a domain to an NFS
partition I get an error message at start time:

# virsh start mydomain
error: Failed to start domain mydomain
error: unable to set security context '110:140' on '/storage/mydomain/vda.img': Invalid argument

The /storage partition is mounted with these options:

# cat /proc/mounts  | grep /storage
nasl002:/storage/ /storage nfs4 rw,relatime,vers=4,rsize=1048576,wsize=1048576,namlen=255,hard,proto=tcp,port=0,timeo=600,retrans=2,sec=sys,clientaddr=,addr= 0 0

If I use a local disk instead, then there is no such

libvirt is version 0.7.7-4, as included with Debian.
Any helpful comment would be highly appreciated.
