Increase hard disk size of QEmu/KVM image

Hi experts,

I have Ubuntu 10.04 Server (no gui) install with the default KVM server stuff that came on the install disk. I have created a virtual Ubuntu server with vmbuilder with a 4gb qcow2 image. I am wondering now how I can resize this virtual drive to 16gb.

Have tried a few things but none of them are working, Any ideas?

Thanks Jelcin, I was hoping this would be the answer as this is what I have been trying, but now hopefully you can help me with it.

How do I boot up qemu with the gparted live cd? Also can I use gparted over ssh or do I need physical access to the server?

sudo qemu -daemonize -boot d -m 512 -hda /home/user/qemu/debian_stable.img -cdrom /home/user/qemu/gparted-live-0.6.2-8.iso -net nic,vlan=0, macaddr=52:54:00:12:34:56 -net tap, vlan=0, ifname=tap0

That's how i start my qemu VM. For you it is important to give qemu "-boot d" for CD-ROM (c would be hdd) and "-cdrom /path/to/gparted" for the path to CD-ROM image.

Thanks, I will give it a go in the next 10-18 hours and report back.

When I try to start using qemu I get "Could not initialize SDL - exiting". From what I have read this is because I'm accessing the server via SSH, rather than a Windowed environment such as Gnome or KDE.

Do I need to install Gnome and then physically access the server to achieve this or can I partition the drive without a GUI? I read that I can simply run e2fsck followed by resize2fs, but I can't do this because the drive is already mounted when I access it over ssh.

Oh I finally got it! I needed to install a vnc server, then add -vnc :1 to the command above. Then I can access it via vnc on my desktop!
