[ovirt-users] Extend HE Disk

Hi, I can see it's possible to edit CPU and memory allocation of HE in the GUI, but it doesn't seem possible to edit the disk. If I try I get a "VM not managed by engine" error. http://lists.ovirt.org/pipermail/users/2015-March/031783.html Is there a method of doing this? I'm running 4.0.5.5-1.el7.centos Thanks, Alan
