Syntax is as same as in case of "xm scsi-attach". Please replace
"0:0:0:0" with keyword "host".

BTW, I suppose the problem you are facing is caused by inconsistency
between backend driver and xend. (The xend support host mode but the
driver does not support it, maybe.) I reccomend you to use xen unstable
to avoid such a problem.
