This patchset includes the latest version of scsifront/scsiback drivers against 3.0.4-testing tree (sorry, terribly overdue). The scsifront/scsiback is a version of blktap that uses SCSI RDMA protocol for transport instead of the xen block protocol. For further information: http://www.xensource.com/files/summit_3/xen-scsi-slides.pdf The drivers exploit the scsi target infrastructure in upstream kernel (already merged for 2.6.20). Like blktap, the user-space scsi target daemon can export raw partitions, regular files, LVM, etc to domU. It also supports the pass-through feature, that is, the daemon directly passes SCSI commands to real SCSI devices (note that this feature needs the very latest kernel so this patchset doesn''t include it). So you can export SCSI devices as is. The drivers are not ready for the performance comparisons. I will do after XEN moves to 2.6.20 since AIO writev/readv enables to easily implement the users-pace daemon code for xen. First, configrue the VM config file like: disk = [''scsi:/var/tmp/image,hda2,w''] Note that hda2 isn''t used at all. This is because I simply exploit blkback/blktap user-space scripts. I will invent own format to handle more complicated scsi configurations later on. Second, start the user-space daemon: # /usr/sbin/tgtd -f Now you are ready to start the domU. _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel
