grow disk image
Rescue an ailing VM running out of diskspace.
This is a viable approach - Start by stopping/ shutting down the VM:
Now we need to grow the qcow2 disk. First, change to the folder with your VM images
cd /var/lib/libvirtNext convert you image to raw (Takes a while)
sudo qemu-img convert -f qcow2 /var/lib/libvirt/images/sparcs_wx.img -O raw ~/mydisk.raw I then expanded the disk to be 20GB (takes a second)
sudo dd if=/dev/zero of=mydisk.raw bs=1M count=0 seek=20480
