Expected results

For rhel9.4, virsh define guest failed on netqe04(Sapphire Rapids server)
https://beaker.engineering.redhat.com/jobs/9346613
[root@netqe04 perf]# virsh define g1.xml
error: Failed to define domain from g1.xml
error: unsupported configuration: Emulator '/usr/libexec/qemu-kvm' does not support virt type 'kvm'
It has no this issue for rhel9.5.
https://beaker.engineering.redhat.com/jobs/9347619
It also has no issue for rhel9.2.
https://beaker.engineering.redhat.com/jobs/9347916

It can work well on my dell 740-57 server.
