This config:
disk = [
'phy:/dev/hosting2_data2/XEN_freebsd_root,0x01,w',
'phy:/dev/hosting2_data2/XEN_freebsd_swap,0x02,w'
]
Gives this output in dmesg:
xbd0: 10240MB <Virtual Block Device> at device/vbd/1 on xenbus0
GEOM: new disk xbd0
xbd1: 512MB <Virtual Block Device> at device/vbd/2 on xenbus0
WARNING: WITNESS option enabled, expect reduced performance.
GEOM: new disk xbd0
and then ls -l /dev/xbd* :
freebsd_domu# ls -l /dev/xbd*
crw-r----- 1 root operator 0, 41 May 18 02:51 /dev/xbd0
crw-r----- 1 root operator 0, 41 May 18 02:51 /dev/xbd0
Hm, I wonder whats busted!
