Right. Let me give it a try first with pseries Qemu. Otherwise I have an access to pseries LPAR too. I can verify it there.Ah, now I realize my problem: I tried with Fedora 43 in a powerpc VM but the modprobe didn't do anything. Looking again: # grep CONFIG_CMM /boot/config-6.17.1-300.fc43.ppc64le CONFIG_CMM=y So modprob'ing won't do as the module is built in.
Right, so doing "cmm.simulate=1" on the cmdline in a Fedora 43 VMs properly creates the CMM device.
