Hot resizing of partitions on HVM
Hi all!
Is it possible to resize the partition of a KVM virtual machine without it is down?
With Xen PV virtual machines, I get this by umounting the filesystem on the VM, detaching the device and then resizing the logical volume and file system in the VMHost. Finally, I attach the device and mount the filesystem on virtual machine. All this without the VM is down.
The procedure that I am using at the moment to resizing a partition in a KVM virtual machine is the following one:
* Shutdown the VM.
* Resize the logical volume which is the partition to resize.
* Boot a KVM VM with PartedMagic [1] and to extend the partition until it has the wished size using GParted.
* Shutdown the KVM VM with PartedMagic.
* Boot the VM with the new partition size.
There is some more efficient way to do it?
Thanks in advance for your replies.
Regards,
Daniel
