[Pkg-libvirt-maintainers] libvirt backport to Bookworm

[Thomas Goirand]

Hi there!

We're about to put in production a 2nd region of our public cloud, which 
is OpenStack based, and using libvirt / kvm.

The hardware we have is rather recent: each compute is equiped with 2x 
EPYC 112 core CPU. That is the EPYC-Genoa CPU model in Qemu.

Therefore, we've installed the latest qemu from bookworm-backports. 
However, libvirt is still too old, and doesn't know about this CPU. 
Therefore, nova thinks it's model is EPYC-Milan, and not EPYC-Genoa.

I've done a backport myself of python-libvirt and libvirt, and it's 
painless to do: just a simple rebuild without changing the package.

Therefore, I'd like to ask: does the libvirt team (guido?) would like to 
upload a backported version of libvirt and python-libvirt to Bookworm? 
If yes, that'd be great. If no, would you mind if I do the upload? Will 
you help maintaining it?

Note that it's working perfectly well for me: I was able to spawn VMs, 
and live-migrate them between compute hosts running the latest OpenStack 
Caracal version.

Cheers,
