Adding additional Virtual disk to increase VM storage

[wahmed]

Is it possible to add additional storage(qcow2, raw or vmdk) into the VM without restarting or shutting down the VM? If it possible, how to make the VM os see that a new hdd has been added.
Thanks!

I have always had to reboot for new hardware to take effect.

Hi,
AFAIK if the OS supports hotplug it's should work (if I remember right, time ago spirit have create some hotplug patches). Normaly you must stop/start the VM that new devices are reconiced by the bios.
Have you tried scsiadd (depends on your OS)?

Yes, just add

"hotplug: 1" to your vm config file.

then simply add your disk with gui.

For linux guests vm, you need to have 2 modules loaded in the vm: pci_hotplug, acpiphp

I just discovered that running Debian Wheezy (kernel 3.2) these modules does not need to be loaded. Adding "hotplug: 1" to the vm config file is all that is needed.
