Qubes-specific VM config files
------------------------------
## Qubes-specific VM config files
These files are placed in `/rw`, which survives a VM restart.
That way, they can be used to customize a single VM instead of all VMs based on the same template.

In case of standalone qubes and templates, just change the Disk Storage settings above. If the standalone fails to start, temporarily increase the `qrexec_timeout`, [as described here](https://github.com/QubesOS/qubes-issues/issues/9251#issuecomment-2121596415).
In case of template-based qubes, the private storage (the /home directory and user files) can be changed in the qube's own settings, but the system root image is [inherited from the template](/doc/getting-started/), and so it must be changed in the template settings.
If you are increasing the disk image size for Linux-based qubes installed from Qubes OS repositories in Qubes 4.0 or later, changing the settings above is all you need to do - in other cases, you may need to do more, according to instructions below.
