Af= ter reboot, all VirtIO devices (SCSI, NIC, memory balloon, etc) are working for 12.0-RELEASE-p12 r356482M! Thanks again! As for those who want the VirtIO working in your Q35 environment, I'll atta= ch the the needed stuff including my fix of the VirtIO's random.c so you don't need to download from Bryan's github repo (comment #8). I don't recommend running in production as it's not officially committed. Also note that this version of the VirtIO, supporting Q35, will break netmap which you'll need = to disable in the kernel configuration prior the build process: /usr/src/sys/dev/netmap/if_vtnet_netmap.h:224:34: error: no member named 'vtntx_shrhdr' in 'struct vtnet_txq' err =3D sglist_append(sg, &txq->vtntx_shrhdr, sc->vtnet_hdr_size); --=20 You are receiving this mail because: You are the assignee for the bug.=
