can't define domain - error: cannot open /dev/null: Operation not permitted



Hi,

i have a two-node cluster running on SLES 12 with pacemaker.
The cluster refused to start the domains on one node.
So i took some of the domains out of the cluster and tried to start it manually.
This is what happened:

virsh # define /mnt/share/vm_documents-oo.xml
error: Failed to define domain from /mnt/share/vm_documents-oo.xml
error: cannot open /dev/null: Operation not permitted

Same with another domain.

On the other node domains are defined and started without problems.
Permissions on /dev and /dev/null are the same:

ha-idg-1:/mnt/share # ll -d /dev
drwxr-xr-x 25 root root 5420 Sep 17 20:47 /dev
ha-idg-1:/mnt/share # ll /dev/null
crw-rw-rw- 1 root root 1, 3 Aug 24 14:39 /dev/null

ha-idg-2:/mnt/share # ll -d /dev
drwxr-xr-x 25 root root 5340 Sep  9 10:31 /dev
ha-idg-2:/mnt/share # ll /dev/null
crw-rw-rw- 1 root root 1, 3 Aug 24 15:48 /dev/null

ha-idg-1 is the one causing trouble.
Both systems SLES 12 SP4, same patchlevel.
livirt is:

Any ideas ?
Maybe a restart would help, but it's Linux, not Windows ...
I'd like to understand what's going wrong.

Thanks.
