Thank you for reply
I try to do it under your guide as follows
# xm block-attach dom6 file:/vm1/template/tp.img sdb2 w
[root@genode012 vmcserver]# xm block-list dom1
Vdev BE handle state evt-ch ring-ref BE-path
2049 0 0 4 7 8 /local/domain/0/backend/vbd/102/2049
2050 0 0 4 8 815 /local/domain/0/backend/vbd/102/2050
and xm block-detach can work
but xm console dom1, then there is not the new disk in dom1
what is wrong with it?
that is the log in /var/log/xen/xend.log as follows:
[2007-02-01 14:08:47 xend 6460] DEBUG (DevController:110) DevController:
