Hi, for quite long time, I've got an issue with my drives configuration on my VMs that do vga passthrough (but I think it's unrelated to passthrough as they would lag without passthrough too). the config is
-drive file=/dev/something,if=none,id=drive-virtio-disk0,format=raw,cache=none,aio=native -device virtio-blk-pci,scsi=off,bus=pci.2,addr=0x1,drive=drive-virtio-disk0,id=virtio-disk0,bootindex=1 what parameter am I missing so the guest would be waiting for IO and not the host pausing it until it can provide the IO? for some time I thought it was windows problem ,but it also shows on my linux guest when the IO lacks. if it matters, the backend is zfs zvol. that's why especially on HDDs it hurts a lot. on SSD it's not that bad but still if I load the IO a lot from multiple sources, it has problem. Thanks, Ghor _______________________________________________ vfio-users mailing list vfio-users@redhat.com https://www.redhat.com/mailman/listinfo/vfio-users
