Resize Disk Image
Resize Private Disk Image
-----------------
There are several disk images which can be easily extended. But pay attention to the overall consumed space of your sparse disk images.

### Private disk image

### Shrinking private disk image (Linux VM)
### Shrinking private disk image (Linux VM, R4.0)
**This operation is dangerous and this is why it isn't available in standard Qubes tools. If you have enough disk space, it is safer to create new VM with smaller disk and move the data.**
1. Create a new qube with smaller disk using Qube Manager or qvm-create
2. Move data using OS tools
3. Delete old qube using Qube Manager or qvm-remove
### Shrinking private disk image (Linux VM, R3.2)
**This operation is dangerous and this is why it isn't available in standard Qubes tools. If you have enough disk space, it is safer to create a new VM with a smaller disk and move the data.**
The basic idea is to:
1. Shrink filesystem on the private disk image.
2. Then shrink the image.
Ext4 does not support online shrinking, so can't be done as convenient as image grown. Note that we don't want to touch the VM filesystem directly in dom0 for security reasons. First you need to start VM without `/rw` mounted. One of the possibility is to interrupt its normal startup by adding `rd.break` kernel option:

### Template disk image
OS Specific Follow-up Instructions
-----------------
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. See also additional information and caveats about [resizing the root disk image].
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. Run this in dom0: `sudo losetup -a`
3. Resize root.img file. Run this in dom0: `truncate -s <desired size> <path to root.img>` (the root.img path can be obtained 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. Execute `sudo resize2fs /dev/mapper/dmroot` in the template.
7. Verify available space in the template using `df -h`
8. Shutdown the template.
9. Restore original netvm setting (if changed), check firewall settings (setting netvm to none causes firewall reset to "block all")
### HVM disk image
In this example we will grow the disk image of an HVM to 30GB.
First, stop/shutdown the HVM.
Then, from a Dom0 terminal (in KDE: System Tools -\> Terminal Emulator) do the following:
~~~
cd /var/lib/qubes/appvms/<yourHVM>/
ls -lh root.img (<--verify current size of disk image)
truncate -s 30GB root.img
ls -lh root.img (<--verify new size of disk image)
~~~
The partition table and file-system must be adjusted after this change.
Use tools appropriate to the OS in your HVM. Brief instructions for Windows 7,
After resizing volumes, the partition table and file-system may need to be adjusted.
Use tools appropriate to the OS in your qube. Brief instructions for Windows 7,
FreeBSD, and Linux are provided below.

Qubes will automatically grow the filesystem for you on AppVMs but not HVMs.
You will see that there is unallocated free space at the end of your primary disk.
You can use standard linux tools like fdisk and mkfs to make this space available.
