I have the same problem with kernel 5.10.0-22, and 23.

When the CPU for the guest is set to "AMD EPYC-Rome Processor", it does work.

But when set to "host-model" on a "AMD Ryzen 9 5950X", which is shown as

"EPYC-Rome" (is the default), the errors occur.

5.10.0-21 works and backport 6.1.0-0.deb11.7 too.

regards

Armin
