Thanks.
Is there any virsh or another command or any file on a system that shows me the
features supported for a certain cpu-model?
Not that I'm aware of. Perhaps others can suggest something I'm not considering.
Eg without going to the sources inside
src/cpu_map/x86_SapphireRapids.xml?
Without being on that cpu when running the command?
I think that's it, which is better than looking at e.g. target/i386/cpu.c in the
qemu sources :-).
BTW, on a libvirt installation you'd likely find those files in
/usr/share/libvirt/cpu_map/.

There are other requests to support SapphireRapids in SLES15 SP5, but it will
take some time to backport patches for all these components and release updated
packages.

Ok. Is it expected to have full support for SP6 in June? Any way to pre-test in
case?
Yes, SapphireRapids will be supported in SP6, which has libvirt 10.0.0. WRT
pre-test, there's a SLE public beta program, but I'm not familiar with the
details. IMO it would be easier to experiment with Leap 15.6, which shares
virt-related packages with SLE15 SP6
