To fix the issue i added to /etc/modules :
xen-gntdev
xen-netback
xen-blkback
Otherwise , "lsmod | grep xen" doesn't report all three of them loaded.
It's impossible to create PV domain. Usual report " vif(0) cannot be connected, hotplug scripts not working"
I would guess system kernel' s .config is incorrect.
Working config should look like :
# ls -l /dev/xen
total 0
crw------- 1 root root 10, 55 2011-07-16 18:33 evtchn
crw------- 1 root root 10, 56 2011-07-16 18:33 gntdev
# lsmod | grep xen
xen_evtchn 13172 1
xenfs 18311 1
xen_blkback 23177 0 [permanent]
xen_netback 27854 0 [permanent]
