This patch brings virito-scsi support to kvm tool.
With the introduce of tcm_vhost (vhost-scsi)
tcm_vhost: Initial merge for vhost level target fabric driver
we can implement virito-scsi by simply having vhost-scsi to handle the
SCSI command.
Howto use:
1) Setup the tcm_vhost target through /sys/kernel/config
[Stefan Hajnoczi, Thanks for the script to setup tcm_vhost]
** Setup wwpn and tpgt
$ wwpn="naa.0"
$ tpgt=/sys/kernel/config/target/vhost/$wwpn/tpgt_0
$ nexus=$tpgt/nexus
$ mkdir -p $tpgt
$ echo -n $wwpn > $nexus
** Setup lun using /dev/ram
$ n=0
$ lun=$tpgt/lun/lun_${n}
$ data=/sys/kernel/config/target/core/iblock_0/data_${n}
$ ram=/dev/ram${n}
$ mkdir -p $lun
$ mkdir -p $data
$ echo -n udev_path=${ram} > $data/control
$ echo -n 1 > $data/enable
$ ln -s $data $lun
2) Run kvm tool with the new disk option '-d scsi:$wwpn:$tpgt', e.g
$ lkvm run -k /boot/bzImage -d ~/img/sid.img -d scsi:naa.0:0
