Description Steven Pritchard 2005-08-30 12:15:41 EDT
Description of problem:
After rebooting to get the latest kernel and xen, xend will not start (which
makes xendomains fail).

# service xend restart
Exception connecting to xenstored: (2, 'No such file or directory')
Trying again...

Version-Release number of selected component (if applicable):
Comment 1 Steven Pritchard 2005-08-30 12:23:21 EDT
Quick workaround:

  mkdir /var/run/xenstored /var/lib/xenstored

I'm guessing those two directories need to go into xen.spec.
Comment 2 Steven Pritchard 2005-08-30 12:26:24 EDT
Next (minor) problem:

  # service xendomains start
  Starting auto Xen domains:/etc/init.d/xendomains: line 50: log_success_msg:
command not found
Comment 3 Steven Pritchard 2005-08-30 13:45:07 EDT
Something still isn't right.  xentop says

  7 domains: 1 running, 6 blocked, 0 paused, 0 crashed, 0 dying, 0 shutdown

Everything is "blocked", whatever that means.
Comment 4 Steven Pritchard 2005-08-30 14:23:58 EDT
Xen block devices seem to be at least somewhat broken.  I'm getting "xen_blk:
Timeout connecting to device!" on boot (and then a panic).

Comment 5 Jon Dowland 2005-09-02 07:23:03 EDT
This problem occurs for me with kernel 2.6.12-1.1447_FC4xen0. The work around
listed (creating /var/run/xenstored and /var/lib/xenstored) appears to work for me.

Comment 7 Rik van Riel 2005-09-12 21:50:50 EDT
Please try today's RPMS from http://people.redhat.com/riel/
Comment 8 Carl Brewer 2005-09-19 22:09:35 EDT
The rpms xen-3.0-0.20050912.fc4.i386.rpm etc work, thankyou

Will they get pushed out to the yum server?  Yesterday I was following the FC4
howto for installing xen, and the rpm's on the yum repository are the broken ones.
