libvirt backport to Bookworm
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,
Thomas Goirand (zigo)
