Pkg xen devel - Mar 2010 - Xend not starting (Lenny backport of Xen 3.4.3-rc3)

Hi,

I have recompiled xen-3_3.4.3~rc3-1 in Lenny, together with the
2.6.32-10 kernel. While my dom0 boots without issue under Xen, xend
refuses to start. I have cut/past my xend.log is bellow.

Is there any reason why a backport of this version of Xen wouldn't work
in Lenny? Should I try the already compiled SID binaries in Lenny
without trying to build myself?

Cheers,

Thomas

When I start xend, it says:
# /etc/init.d/xend start
Starting XEN control daemon: xenstored xenconsoled xendERROR Internal
error: Could not open event channel interface (22 = Invalid argument)
FATAL: Failed to open evtchn device: Invalid argument
 failed!

and the xend.log has:

I don't see why not.

Do you have the event channel driver loaded? What does /dev/xen contain?

I have a feeling you also need to backport xen-utils-common (source:
xen-common) in order to get an /etc/init.d/xend which loads the correct
modules.

Even if you can deceive people about a product through misleading statements,
sooner or later the product will speak for itself.
