Hello All,

I am using Centos 6.3 with libvirt 0.910 and qemu-kvm 0.12

I had to resize a qcow2 disk, and came across several issues;

I used this command to resize the image:

sudo -i /usr/bin/qemu-img /var/lib/libvirt/images/mydisk.img resize +100G . The disk is attached using virtio.

For my resizes I use libguestfs's virt-resize [1] tool. It's been working flawlessly so far -- it resizes both the image file/device and partitions inside that image. I can't recommend it enough. Best, Hristo [1] http://www.libguestfs.org/virt-resize.1.html
