Ok, looks like a rendering bug following migration .. if I wait a few minutes and refresh, it reverts to the "onevm show" value ...

Ups my mistake, Storage tab I meant... When you save a disk you can do it live or deferred, deferred is when the VM is shutdown, live calls the cpds script to copy the disk to the datastore.

Re; the bug, looks like rendering, gone back to it now and it looks fine ...

I must admit to being a little confused, my "capacity" tab on VM's has only a "resize" button .. which is inactive (?)
(cpds sounds ideal if I can find how to use it .. :) )

Hi
As you know there are two types of snapshots, system and disk. Disk only snapshots are handled through the capacity tab in sunstone and eventually by the CPDS script in the TM. System snapshots are handled by the snapshot script of VMM.
There are no plans to redesign this, disk snapshotting can use a custom storage facility through "cpds", but system snapshots will be handled through the hypervisor....
Note that system snapshots require also to checkpoint the memory state of the system, thats the reason for requiring qcow2 in kvm. So I am not really sure how this two processes, memory and disk snapshot, can be orchestrated outside of libvirt, maybe libvirt hooks?
About the bug, I am wondering if this is a rendering issue or something deeper, could you send the output of:
onevm show <VM_ID> -x
Cheers
Ruben

ich at the moment
relies entirely upon the QEMU snapshot facility, which means you can really only snapshot QCOW
images. Before I start to modify remotes/bmm/kvm/snapshot*, is there a way or are there any plans
to move snapshot functionality to the drivers such that we can use a custom snapshot facility on
a per storage facility basis?
Case in point;
At the moment there seems to be a script which does this;
virsh --connect $LIBVIRT_URI snapshot-create-as $DOMAIN (which is QCOW2 only?)
I would like it to be able to handle this;
vdc-tool -n ON_IM_81 --mksnap "First Snapshot"
> :: Snapshot created [First Snapshot]
vdc-tool -n ON_IM_81 --lssnap
+----------+--------------------------------------+----------+----------+----------------------+
| UniqueID | Snapshot Name | Size | Blocks | Created@ |
+----------+--------------------------------------+----------+----------+----------------------+
| 1 | First Snapshot | 662.53M | 370404 | 20 Oct 2013 09:55:08 |
| | 6c0ca1c0-9d62-474a-83fc-369fa01d4068 | | | Root: 1196295401 |
+----------+--------------------------------------+----------+----------+----------------------+
Number of snapshot blocks used (370404) taking ( 662.53M)
Current committed blocks = 652079
Current blocks (0 ) and current size ( 0.00b)
Obviously the vdc-tool output can be tweaked as necessary .. I would like to be able to integrate
this into libvirt, but the snapshot API in libvirt appears still to be on the drawing board whereas
I already have a working / usable snapshot facility ... any thoughts ?
Incidentally, I think I just spotted a bug on the Placement log;

We've accumulated 30d of total time overnight ?!
(yes, the clocks are in sync ...)
