Debian builds packages on alpha and, even though it's no longer
considered a release architecture, it works just fine and keeps up
with updated software components:
$ uname -a
Linux debian-alpha 6.6.8-alpha-generic #1 Debian 6.6.8-1
(2023-12-22) alpha GNU/Linux
That's from a Debian installation running under qemu-system-alpha
that I've created over the weekend. Bit slow, as one would expect
when TCG is involved, but other than that perfectly functional.
In fact, this tiny patch is all that's needed to get the Debian
package for libvirt to build successfully. And it works too, at least
when it comes to the client part:
$ ip a show dev enp0s2
2: enp0s2: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel
state UP group default qlen 1000

--xpath /domain/devices/interface/mac
<mac address="52:54:00:fd:42:9b"/>
Here I'm connecting to the host's libvirtd from within the guest,
just for convenience. I could just as easily connect to a remote
hypervisor.
I could of course keep this patch as a downstream-only change in the
Debian package, but I see no point in not accepting it upstream,
especially since the maintenance burden it causes is literally zero.
Please reconsider :)
