Hello all,
yesterday I upgraded my 3.6.x to 4.0 and got stuck with obviously not
being able to shutdown HE VM itself ("shutdown all VMs" required for
increasing the compatibility level to 4.0). As I luckily already had a 4th
pure computing node, rgolan friendly walked me through the process of
creating a new V4 cluster and moving that 4th node to it. The purpose was
to free up the default cluster, to be prepared to increase to V4.
The next step was to migrate the HE VM to the new cluster ("automatically
chose host", as there is only one host for that new cluster). Everything
went well, but (as rgolan asked to check) the cluster assignment for the HE
VM in the edit VM dialogue still shows "Default" and an attempt to increase
the compatibility of "Default" cluster of course didn't work ("first
shut
down all VMs!"). The migration of another VM to that new cluster on the
other hand worked without a glitch.
Attached is the engine.log. Relevant entries should start at around "
2016-06-29 00:53:20 ", it should be the time I created the new cluster and
moved pure computing node " slp-ovirtnode-04 " to it. Please ignore the
glusterfs brick entries, I have additional disks ready to be added, but
this is another story ;)
Hopefully there is a way to entirely move the HE VM to the new cluster.
Thanks and regards
mikelupe

At the end of the migration we prevent that action on the hosted engine vm
