I would suggest the following :
1. Pause the virtual machine ( with virsh for example )
2. Take a snapshot of the logical volume.
3. Unpause the virtual machine
4. Convert the snaposhot ot qcow2.
I'm doing something similar with a python script.

Subject: converting lvm based Virtual Machine to qcow image.
A long time back I had asked as how to back up OS running on KVM in an
LVM setup.
Here are the excerpts from the message
"One way to take a backup is to convert the LVM volumes to compressed qcow2
images, like this:
# qemu-img convert -c -f raw -O qcow2 /dev/nintendo/lvm1 /backup/lvm1.img"
I would like to know do I need to shut down the VM to be able to use
the above command.
