Description Bryan Mason 2009-09-09 23:13:40 UTC
Description of problem:

   Running 'xm reboot -a' may result in some DomUs not being
   rebooted, and others being in an inaccessible state.

Version-Release number of selected component (if applicable):


How reproducible:

    Most of the time.

Steps to Reproduce:

    1. Start several pv guests.
    2. run 'xm reboot -a'
Actual results:

    Chaos.  After the attempted reboot of all guest domains, some (or
    all) of the domains will not be restarted.  Running 'xm list'
    shows something like:

        # xm list
        Name                              ID Mem(MiB) VCPUs State   Time(s)
        Domain-0                           0      444     1 r-----    119.9
        Zombie-rhel52-test                 9      256     1 ------      5.0
        Zombie-rhel52-test                10      256     1 ----c-      0.2

Expected results:

    Joy and harmony.  All guests should restart successfully.

Additional info:

    It is reported that this worked fine in xen-3.0.3-64.el5_2.3, but
    is a problem with xen-3.0.3-64.el5_2.9 as well as the latest
    version in RHEL 5.4 (xen-xen-3.0.3-94.el5).  I have verified the
    problem with xen-3.0.3-80.el5.

I suspect this could be caused by bug 518104, I'll prepare testing packages to check if my suspicion is right...

Comment 3 Jiri Denemark 2009-09-10 12:24:02 UTC
Could you please try the packages at http://people.redhat.com/jdenemar/xen/bz522274/ to see if that fixes your issue?


Comment 5 Jiri Denemark 2009-09-16 07:30:30 UTC
Great, thank you very much for the testing which confirms that this bug is solved by patches for bug 513604 and bug 518104. I'm going to close this bug as a duplicate of the latter (although both of them are most likely needed). Both BZs are nominated for Z-stream, so once they are approved, built and tested by QA, you should be able to get them as an update.
