/etc/init.d/xencommons start hangs

ls00722
Hi all:
   I've sucessfully built xen toolstack, but "xl list" just hang, then i
realized i have to start the xencommon service, however
"/etc/init.d/xencommons start" hang as well,  the script calls
"xen-init-dom0", that's where it hangs.
   Any idea how I debug this problem? why there is not even an error message
showing?

Thanks
Chris

It sounds like what happens when xenstored can't be started.

You can try to start xenstored or oxenstored manually, and see what
happens. Or you can also strace xen-init-dom0, and see where it
actually hangs.

Regards,
Dario

My first question would have been: did you reboot into Xen?

Or to avoid any further guesswork:

Please give us a clue what happened by:

- specifying Xen and dom0 version
- sending a boot log

According to the script:

       echo Setting domain 0 name, domid and JSON config...
        ${LIBEXEC_BIN}/xen-init-dom0

I don't see the xen-init-dom0 is being called? yet it hangs after printing
out "setting domain 0 name, domid and JSON config".

Appreciate any idea to proceed for debugging.
Thanks
chris

Re: /etc/init.d/xencommons start hangs

In reply to this post by Dario Faggioli-4
Hi Dario:
   One more thing, seems like the xencommons script invoke
"/etc/xen/scripts/launch-xenstore", and I tried to manually run that script,
it didn't produce anything, no error either.
  Manually run "xenstored"  gave me error:

FATAL: Failed to initialize dom0 state: No such file or directory.

Thanks
chris

Mmm.. Actually, I was suggesting to manually run, and maybe strace,
either xen-init-dom0 or xenstored directly.

Well, I don't have a xencommons script handy right now, but
xen-init-dom0 being "called" might very well be the clone above.

And then the script waits for xen-init-dom0 to finish, but that,
according to your previous email, never happens, which explains why the
script itself is stuck in the wait().

But it's the reason why xen-init-dom0 never completes that we're after!

Re: /etc/init.d/xencommons start hangs

ls00722
Hi dario:
  I suppose the xen-init-dom0 needs to communicate with xenstored using some
sort of local socket?  Apparetnly xenstored didn't start succesfully, so
that might be the cause of xen-init-dom0 hangs?

Anyway, I tried "strace xenstored", here is the result:

strace xenstored
