*The next step towards the final goal can be found [here](https://github.com/mnlipp/kube-qemu-legacy).*
*The final solution, however, is the [VM-Operator](https://jdrupes.org/vm-operator/).*
# AlmaLinux 9.1 etc. and VMs with Spice
RedHat has decided to
[drop Spice](https://bugzilla.redhat.com/show_bug.cgi?id=2030592)
from the packages shipped with RHEL. As discussed in various places
(e.g.
[here](https://www.reddit.com/r/redhat/comments/ux38f3/why_was_spice_qxl_removed_from_rhel_9/)),
this is bad news for anybody who does serious work with VMs that run on
RHEL 9.1 (in whatever flavour). Without support for cut & paste, performant
access over the internet and USB redirection the VMs aren't usable any
more for many use cases.
Nevertheless, there are good reasons why I want to stick to running
a RHEL 9.1 based system on my server. So I need a solution.
One approach is to replace the libvirt/qemu packages with the
[Fedora packages](https://github.com/ladar/qemu-spice-el9)
on the server. This works. But with several hundred packages
being replaced, I do have some concerns regarding the stability of
my server.
Luckily, another approach has already been pioneered in the
context of ProjectAtomic: run libvirt
[in a Container](https://github.com/projectatomic/docker-image-examples/blob/master/rhel-libvirt/libvirtd/Dockerfile).
I've taken this as a starting point and made some adaptions.
I've put everything in directory [fedora-based](fedora-based) because
it is a Fedora-based container for libvirt. In case
RedHat drops Spice support from Fedora as well, it shouldn't be
too difficult to create a sibling directory with e.g. an Arch
based container for libvirt.
I have tested my approach with AlmaLinux 9.1, that's why you find it
in the title. It should run on RHEL and Rocky Linux as well.
Note that I'll dedicate only limited resources to project (basically
keep it working for my use case). IMHO the way to go is
a kubernetes operator that runs VMs without libvirt, because libvirt
duplicates several mechanisms that k8s provides already. And considerng
the number of packages required as dependencies of libvirt,
it has grown too complex.
