Subject RE: [DISCUSS] Enabling storage xenmotion on xenserver 6.1
Date Wed, 09 Jan 2013 01:51:05 GMT
I assume clone is a kind of snapshot in the term of VHD chain,
Does XenMotion has same restrictions on clone?

For fast provision, right now , on XenServer, root disk is cloned from template.
Before any snapshot, root disk is already a VHD with parent VHD which is template, do you
know if this has any impact for XenMotion ?
