Description

The test setup has 2 compute nodes in a cluster running XS6.2 managed by CS4.3
When the master node is switched to maintenance mode we expect the userVMs and systemVMs to migrate to the slave node.
However we observe that the slave node gets restarted during migration.

Seeing these messages on the console of the host which is moving to maintenance mode.
