Subject RE: [DISCUSS] Enabling storage xenmotion on xenserver 6.1
Date Tue, 08 Jan 2013 09:57:35 GMT
Hi Swamy,

In the following scenario when a VM has disks in different repositories, all the virtual disks
of the VM will be moved to the same destination repository. Moving individual disks of the
VM to different repositories can be done, but it'll involve taking inputs from the user as
to which disk should be moved to which repository. What do you think, should this option be
also provided?

Regards,
Devdeep
