command so that it actually changes the live system. Or perhaps you just have to rescan the
scsi controller inside the vm. If online resize doesn't work at all, there's code in resizeVolume
you can use to only support offline resize (checks that the VM is stopped, used by Xen).

I didn't find the function in vim25 now. I'll try to find a way to fix it.
