I had this issue and the better way to resolve it 100% was to statically compile into kernel as opposed to using as a module.
Thanks

I think you should load xen-evtchn module before start xencommons, try to do that if you have compiled xen-evtchn as a module
#modprobe xen-evtchn
Hope that helps

I firstly run xencommons start following, the result is
Starting xenstored...FATAL: Failed to open evtchn device: No such file or directory
..............................
Could not start xenstored.
Then run xend start, no message deplay. And here is the error in the xend.log:

At last ,run xm list:
Error: Unable to connect to xend: No such file or directory. Is xend running?
I find a recent bug(bug 361345) likes this issue, but i do not know how to solve it.
Thanks.
