Hi,
Also Caching=None is set because there is a disk cache on the disk.
Would double caching would slow down I/O?
Thanks,

Hello Richard,
Sorry for the late reply.
The output from the command is:
[root@kvm2 images]# qemu-img info Stage.img
image: Stage.img
file format: qcow2
virtual size: 100G (107374182400 bytes)
disk size: 16M
cluster_size: 65536
The reason why I am using "None" for caching is because any other caching
technique doesn't allow migrations. Last time I checked "None" didnt
migrate.
Thanks,
James Harrison

What is the output of:
qemu-img info /var/lib/libvirt/images/stage.qcow2
Also I wouldn't personally use cache=none. I would use
cache=writeback instead.
