Hello Guix,
i wanted to recommend some changes to libvirt which would improve the
usability of libvirt.
1) OVMF(UEFI) capability with QEMU. In NixOS you can achieve this with
virtualisation.libvirtd.enable = true;
virtualisation.libvirtd.qemuOvmf = true;
virtualisation.libvirtd.qemuVerbatimConfig = ''
nvram = [ "${pkgs.OVMF}/FV/OVMF.fd:${pkgs.OVMF}/FV/OVMF_VARS.fd" ]
user = "1000"
'';
the "user" part is not necessary but is required for system VMs in
combination with qemu's pulseaudio driver. qemuVerbatimConfig is the
config that is at /etc/libvirt/qemu.conf in traditional GNU/Linux
distributions.
2) Using a modified QEMU with libvirt. A modified QEMU could help
sometimes. A way to specify which QEMU package to use would be helpful
to resolve issues with newer qemu versions or patches which are not
upstream. While in NixOS you could add patches like this
nixpkgs.config.packageOverrides = pkgs: rec {
qemu = pkgs.qemu.overrideAttrs (attrs:{
patches = (lib.filter (x: ! (lib.hasSuffix
"fix-hda-recording.patch" (builtins.toString x))) attrs.patches) ++ [
/path/to/qemu.patch ];
}
);
};
to the QEMU package, i don't think this is possible in GuixSD.
Thank you for your work. Please let me know what you think.
