Rusty, currently virtio_blk uses one major number per device. While this works quite well on most systems it is wasteful and will exhaust major numbers on larger installations. This patch allocates a major number on init and will use 16 minor numbers for each disk. That will allow ~64k virtio_blk disks.
There's are some other limitations to the number of virtio block devices. For instances...
sprintf(vblk->disk->disk_name, "vd%c", virtblk_index++);
This gets bogus after 64 disks. We also have a hard limit for virtio-pci based on the number of PCI slots available. One thing I was considering was whether we should try to support multiple disks per virtio device.
Otherwise, this patch looks good to me. Regards, Anthony Liguori _______________________________________________ Virtualization mailing list Virtualization@xxxxxxxxxxxxxxxxxxxxxxxxxx https://lists.linux-foundation.org/mailman/listinfo/virtualization
