we had a failure in ost that was really hard to debug: http://jenki= ns.ovirt.org/job/ovirt-master_change-queue-tester/3795/

There are no failures in the logs and the test itself was terminated by = a timeout. It took the vms a long time to download packages and install and= didi seems to think that this is due to limited entropy on the physical ho= st.

we need to review this issue and increase the entropy on the hosts.

we had a failure in ost that was really hard to debug: http://jenkins.ovirt.org/job/ovirt-maste= r_change-queue-tester/3795/

There are no failures in the logs and the test itself was terminated by a timeout. It took the vms a long time to download packages and install and didi seems to think that this is due to limited entropy on the physical host.

we need to review this issue and increase the entropy on the hosts.
