I have
a Win 2008 KVM based guest VM running on
a Ubuntu 10 host. It is
a raw image of 22G. I want to add
a "data" drive which would show up as "D:\" drive on the guest. I first created
a raw image using:
qemu-img create -f raw ~/vmdisk2.img 50G
Then, tried attaching it using virsh attach-disk. When that did not work, I tried editing the xml file of the VM directly. Both did not seem to work.
I would greatly appreciate any help on how to do this
and what the best practice is. I want to keep the base image small, so that I can clone it (hopefully)
and then
attach necessary storage based on the application at hand.
Update: The xml of the vm before adding the second drive:
