Hi,
As per subject, is there a way to reduce diskspace for a VM. I have a VM with 200GB but would like to reduce the diskspace to 100GB.
Please advise.
Thanks!

Perhaps shriking the partition using gparted inside the VM?
Otherwise I can't figure out how to shrink a raw, qcow file under KVM for example...
Hi,
But I would like the diskspace to be release to the hardware node so that i can create another VM as my hardware node is running out of diskspace. I presume that using Gpart only reduce the diskspace on the VM but it will not be release to the hardware node?
Thanks! YongSan

What are you using to virtualize those VMs?
Hi,
Using KVM, qemu.
Thanks!

I can only think of creating a smaller qcow file, clonning using dd the contents of the oversized qcow/raw HD to that newly qcow file...although is not the best solution.
Maybe someone else could bring a better solution because there's no much info on KVM just a little under Xen... :(
Hi,
I am trying to boot that particular VM which I want to resize using gparted ISO. May I know how can I boot a VM using a ISO file?
Thanks!

Place the gparted iso file somewhere you can access it from the VM. I would recommend placing it on the Centos server that hosts the VM. I keep all my ISO files in a folder named ISOs.
I run the gnome desktop on my servers, so I use VNC to remote control the server. I would run the virt-manager gui to shut down the VM guest, connect the guest's CD to the iso file, and change the boot options to boot from the CD. Of course, you can do all this from the command line, and I'm sure you can google information of how to do it that way.
With gparted, I think you can backup the VM over the network to a share. So, I would first backup the VM, then resize the VM disk with gparted and make sure it boots, then backup the VM again, create a new smaller disk for the guest, and restore the smaller backup image.

Hi,
Thanks. Yes I am also using gnome and using VNC to access it. But I could not find a simple way to connect the guest's CD to the ISO file. The option under boot option is only either harddisk, CD or PXE. So how can I connect the guest CD to the ISO file?
Thanks!

Using the virtual machine manager, in the hardware section of the guest, you should see a cd rom drive listed. It's usually labeled 'Disk hdc', and the icon looks like a CD.
It has a Connect button.
