Comment 2 Radek Novacek 2016-05-18 08:52:31 UTC

This is caused by the fact that the filesystem is readonly in RHEV-H.

Can be the file /var/lib/virt-who/key made writable? Or rather whole directory /var/lib/virt-who/? virt-who uses this directory for its internal files which are required for its correct operation. Thanks.

Comment 3 Fabian Deutsch 2016-05-18 10:36:23 UTC

This bug appeared on RHEV-H NG which has a writable filesystem on /var.

Thus it is not a read-only problem.

Eko, do you have a traceback or more detailed logs?

Comment 4 Eko 2016-05-19 09:05:07 UTC

Fabian, I checked it again with rhev-hypervisor7-ng-3.6-20160518.0.x86_64.
can't reproduce this issue any more. verified it.
