I wonder if you could check that the following is correct information. Also - at the bottom of the email - a puzzling problem or bug. At the libvirt level, we refer to virtio-scsi disks using: ...
On the qemu command line, the controller becomes: -device virtio-scsi-pci,id=3Dscsi0,bus=3Dpci.0,addr=3D0x2 (For Q35, it would specify a PCIe bus and the address would also be a bit different). On the qemu command line, the disk becomes: -drive file=3Ddisk.img,format=3Draw,if=3Dnone,id=3Ddrive-scsi0-0-0-0 -device scsi-hd,bus=3Dscsi0.0,channel=3D0,scsi-id=3D0,lun=3D0,drive=3Ddri= ve-scsi0-0-0-0,id=3Dscsi0-0-0-0,bootindex=3D1 In libvirt
refers back to the element. You can add more than one virtio-scsi controller, but each one takes a PCI slot, and the number of PCI slots can be limited (or on Q35, there are no effective limits but there are other architectural constraints). In libvirt,
refers to the virtio-scsi "channel". The current virtio-scsi driver in qemu has a hard limit of 1 channel, so you can only use bus=3D"0" (or channel=3D0). Open question: Will this limit ever be increased? In libvirt,
refers to the virtio-scsi "scsi-id" (internally in the driver called just ".id"). You can use any target from 0 to 255 inclusive. In libvirt,
refers to the virtio-scsi "unit" ie the SCSI LUN. You can use any LUN from 0 to 16383 inclusive. Open question: What does the bus=3Dscsi0.0 parameter mean? The maximum number of drives on a single controller is therefore 256 * 16384 =3D 4194304. However there are other limits to consider: (1) qemu is limited by the number of files it can open (ulimit -n / RLIMIT_NOFILE). On Fedora, this is 1024 (soft) or 4096 (hard), although of course it may be increased. (2) libvirt has trouble with > about 8000 drives (https://bugzilla.redhat.com/1443066). (3) The Linux kernel used to be limited to three letter drive names (ie. up to /dev/sdzzz, or 18278 drives), but in modern kernels this is no longer an issue. (4) The Linux kernel is quite slow at enumerating drives. I couldn't get past 4000 drives without hitting SCSI layer timeouts. Not tested yet: Does hotplugging work on individual LUNs? ---------------------------------------------------------------------- Currently libguestfs puts each disk on a separate target (target=3Di unit=3D0), and therefore has an effective limit of 255 disks (256 - 1 because the appliance uses a disk). When I changed libguestfs to use LUNs instead of targets (target=3D0 unit=3Di), I got a peculiar bug. It looks like there is some kind of race when enumerating the device, where /sys is populated before the device is actually available. See the below boot log, and compare it to the init code: https://github.com/libguestfs/supermin/blob/master/init/init.c#L176 * fp =3D fopen ("/sys/block/sdab/dev", "r") succeeds at line 181 * we read major:minor from fp at line 230 * we mknod ("/dev/root",...) at line 245 * we mount ("/dev/root", "/root", "ext2"...) at line 262, which fails with EINVAL * shortly after that, kernel messages indicate that sdab has been attached.
