Last updated on MARCH 31, 2016

Applies to:

Oracle VM - Version 3.0.1 to 3.1.1 [Release OVM30 to OVM31]
Linux x86-64
Linux x86
Linux SPARC

Symptoms

Any attempt to start or migrate a VM guest fails. Other hosts in the server pool do not show this behavior.

Examining the AdminServer logs shows a flood of entries:

ERROR (service:96) catch_error: Lock file /var/run/ovs-agent/vm-list.lock failed: timeout occured.
Issue arose when a new Template was getting imported into OVM:
[2013-11-20 14:24:02 10478] DEBUG (service:77) import_template: ('0004fb0000030000961cc613c6a780c7', '0004fb000014000031b5111cacdbac52', ['http://localserver01/yum/rhel59-v01.tgz'])
