Hi,
I am trying to take snapshot of volume on KVM (RHEL6.3) and I am getting an
exception that says it isn't supported:

I am on build: Git Revision: 995bab60385f7d663680ef6f5342056c6db3d305
It's working fine on Ubuntu 12.04 and XS 6.0.2.
Here's the DB extract of 'host' table on RHEL6.3 vs Ubuntu12.04:
RHEL 6.3:
=======
mysql> select id, status, type, hypervisor_type, capabilities from cloud.host;
+----+--------+--------------------+-----------------+--------------+
| id | status | type | hypervisor_type | capabilities |
+----+--------+--------------------+-----------------+--------------+
| 1 | Up | Routing | KVM | hvm |
| 2 | Alert | SecondaryStorage | None | NULL |
| 3 | Up | SecondaryStorageVM | NULL | NULL |
| 4 | Up | ConsoleProxy | NULL | NULL |
| 5 | Up | Routing | KVM | hvm |
+----+--------+--------------------+-----------------+--------------+
5 rows in set (0.00 sec)
Ubuntu 12.04:
===========

Am I missing any additional package to be installed for snapshot to work on KVM?
I have the following versions of qemu-img and qemu-kvm installed on my host:
[root@rhel63 ~]# rpm -qa | grep qemu
gpxe-roms-qemu-0.9.7-6.9.el6.noarch
qemu-img-0.12.1.2-2.295.el6.x86_64
qemu-kvm-0.12.1.2-2.295.el6.x86_64
Thanks,
Sowmya
