=== Wayland ===

In order to run on Wayland, virt-manager must be ran under XWayland with `$ GDK_BACKEND=x11 virt-manager` or a gdk cursor must be set. An example of setting a gdk cursor with home-manager is as follows:

=== Unable to find 'efi' firmware ===

The following guide is to fix the following error which will occur when starting a virtual machine after NixOS upgrade:

<code>Error: Error starting domain: operation failed: Unable to find 'efi' firmware that is compatible with the current configuration</code>

Solution:

# Delete old generations: <code>nix-collect-garbage -d</code>

# Find where the EFI boot loaded file is located: <code>find /nix/store/ -maxdepth 1 -type d -name "*qemu*" | xargs -I {} find "{}" -type f -name "edk2-x86_64-secure-code.fd"</code> Find the dir holding the latest qemu. The directory should be something like: <code>xbfjilai721rzd9rf9dhhpv03xza4xp4-qemu-9.1.3</code>. Take a note of this directory name.

# Open VM in virt-manager, go to XML and within the <code><os ...></code> tag:

## Edit <code><loader ...></code> with the above directory name

## Edit <code><nvram ...></code> with the above directory name.
