Hello g, hello All,
thanks for the reaction.
I see nothing on the Xen site applicable to my ( relatively simple )
Xen-on-Centos6 setup.
I don't want to install a control panel or Xen Xcp.
I will try this one :
http://www.jansipke.nl/creating-backups-of-running-vms-in-xenserver/
* Search for the uuid of the VMs to backup
# xe vm-list is-control-domain=false
is-a-snapshot=false
* Create a snapshot of each (running) VM
# xe vm-snapshot
uuid=d61bfc1a-33b2-5406-7ea5-76e4f7113220 new-name-label=snapshotname
* Save the snapshot to file
# xe template-param-set is-a-template=false
ha-always-run=false uuid=b759625c-eab5-4e0f- be5e-a05bcbad869a
#xe vm-export
vm=b759625c-eab5-4e0f-be5e-a05bcbad869a filename=filename.xva
* Remove the created snapshot
# xe vm-uninstall
uuid=b759625c-eab5-4e0f-be5e-a05bcbad869a force=true
and see how it goes.
Greetings to All
