Some more info :

  * This cluster was using a ZFS over iSCSI storage a few months ago, without issue
  * A VM with ZFS over iSCSI disk started with "qm start" can be migrated from the web interface (so, the start phase on the new node is not affected when done in a migration context)
  * The problem goes away as soon as I replace the ZFS over iSCSI storage with a image on an NFS server (no other change)

Daniel
