Thanks Rich.

I'm actually asking this more for RHEV usage.  I don't know if you're
directly involved with RHEV development, but I do know that they are
using more of your tools in RHEV now.

I have an export storage domain that I have exported a VM to.
Supposedly, according to the RHEV documentation, it is exported as an
OVF format.  However, it creates the disk images as logical volumes on
the export domain, with GUID's instead of easy to understand names.
What I am attempting to do is find a way to use virt-v2v to pull the
VM off of my export storage domain and convert it into a KVM VM to
store on an external hard drive as another layer of backup.

virt-v2v doesn't support export from RHEV, only import. However, it doesn't sound like you need V2V here. Once you've exported the VM to an export storage domain, you can simply back up the files in the export storage domain. tar would work as well as anything else here.

I have a couple of questions about virt-v2v.

The first one is, when will it support iSCSI connections (if at all)?

Exporting a libvirt or ESX VM which use iscsi for storage should work fine now.

If you're exporting *to* RHEV, we can only write to an NFS export storage domain. However, when you import this guest into RHEV, it can be written to any storage, which would include iscsi.

Also, I see in the man page that virt-v2v can work over an SSH
connection, however I couldn't find an example on how to do this.
Does anyone have a quick walkthrough on how to do that?

virt-v2v -ic xen+ssh://xen.server/ -o rhev -osd rhev.nfs.server/export --network rhevm rhel5pv64
