[Qemu-devel] [Bug 811593] [NEW] Loading kernel 3.0.0-5-generic under Xen 4.1 doesn't create /dev/xen/gntdev |
Date: |

Public bug reported:
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 configuration (after Dom0 kernel gets loaded) 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]
xen_gntdev 17676 0
