Description Florian Best univentionstaff 2013-10-29 15:44:36 CET
Lacking functionality imho:
* create a snapshot directly as grid action (in the overview of all VMs)
* see the virtualization server node in the grid and on the detailpage
* start/stop/etc. the instance on the detailpage
* refresh the values on the detailpage
Comment 1 Florian Best univentionstaff 2013-10-30 13:19:09 CET
After reverting a snapshot, which was done when the VM was STARTED, I am able to modify the VM settings. Normally the detailpage should be greyed out if the VM runs.

Currently the CPU and Memory usage is shown for a pool/node. It would be nice to also show the HDD usage.

For storage pools there's Bug #22714.

PS: pools are more complicated, as there may be more than one pool/HD and they're not interchangeable: All RAM-cells and CPU cores are equal (we're talking about SMP here), but pool contain different volumes, so an average over all resources does not make sense for pools. Showing all pools is also not that clever, as in most cases you'll have shared pools and showing them as tiny graphics again and again for each host is a waste of space.

* A VM can't be directly stopped if it is currently suspended.
* When trying to migrate a VM which is currently suspended one will get a failure message. The frontend could restrict the migrate functionality to VMs which are turned off.

* When changing a medium of e.g. a DVD drive the dialog should load the actual settings.

It should not be possible to add a snapshot with the same name as one which already exists (a better error message should be shown).
