vhost-device-scsi
This is a Rust implementation of a vhost-device-scsi daemon.
Usage
Run the vhost-device-scsi daemon:
vhost-device-scsi -r --socket-path /tmp/vhost-user-scsi.sock /path/to/image.raw /path/to/second-image.raw ...
Run QEMU:
qemu-system-x86_64 ... \
-device vhost-user-scsi-pci,num_queues=1,param_change=off,chardev=vus \
-chardev socket,id=vus,path=/tmp/vhost-user-scsi.sock \
# must match total guest meory
-object memory-backend-memfd,id=mem,size=384M,share=on \
-numa node,memdev=mem
Limitations
We are currently only supporting a single request queue and do not support dynamic reconfiguration of LUN parameters (VIRTIO_SCSI_F_CHANGE).
Features
This crate is a work-in-progress. Currently, it's possible to mount and read up to 256 read-only raw disk images. Some features we might like to add at some point, roughly ordered from sooner to later:
- Write support. This should just be a matter of implementing the WRITE command, but there's a bit of complexity around writeback caching we need to make sure we get right.
- Support more LUNs. virtio-scsi supports up to 16384 LUNs per target. After 256, the LUN encoding format is different; it's nothing too complicated, but I haven't gotten around to implementing it.
- Concurrency. Currently, we process SCSI commands one at a time. Eventually, it'd be a good idea to use threads or some fancy async/io_uring stuff to concurrently handle multiple commands. virtio-scsi also allows for multiple request queues, allowing the guest to submit requests from multiple cores in parallel; we should support that.
- iSCSI passthrough. This shouldn't be too bad, but it might be a good idea to decide on a concurrency model (threads or async) before we spend too much time here.
