It is not possible to create a directory for the VM on the target host. Permissions on the home directory can be incorrect, or pstorage cluster can be inaccessible in case the node is a client of a pstorage cluster.


Check which Home directory is configured for the virtual machines:

# prlsrvctl info | grep -i Home
VM home: /pstorage/storage

Check whether the directory is accessible:

# ll /pstorage/storage
ls: cannot access /pstorage/storage: Transport endpoint is not connected

If the node is a member of a pstorage cluster and the message above is displayed, restart "pstorage-fs" service:

# service pstorage-fs restart

In case the node is not part of pstorage and the folder is accessible, check permissions on the folder.
