### Template disk image
If you want install a lot of software in your TemplateVM, you may need to increase the amount of disk space your TemplateVM can use.
1. Make sure that all the VMs based on this template are shut off (including netvms etc).
2. Sanity check: verify that none of loop device are pointing at this template root.img: `sudo losetup -a`
3. Resize root.img file using `truncate -s <desired size>` (root.img path you can obtain from qvm-prefs).
4. If any netvm/proxyvm used by this template is based on it, set template netvm to none.
5. Start the template.
6. Now you can execute `sudo resize2fs /dev/mapper/dmroot` in the template.
7. Verify available space in the template.
8. Shutdown the template.
9. Restore original netvm setting (if changed), check firewall settings (setting netvm to none causes firewall reset to "block all")
