Description Michael Richardson 2006-05-18 15:02:23 EDT
Description of problem:

A newly installed FC5 system, having run yum update, fails to be able to start
xend. The xend.log is attached.

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

bronwen-[~] root 14 #rpm -qf /usr/sbin/xend

bronwen-[~] root 15 #rpm -qf /boot/vmlinuz-2.6.16-1.2111_FC5xen0

How reproducible:

First system (trout) was upgraded from FC5test2, and had this problem.
A second system had just been installed from final CD, and it failed as well.

Steps to Reproduce:
Actual results:

Expected results:

Additional info:

(maybe Xend is not compatible with kernel?)

An strace of xend showed it trying to start /usr/sbin/xenstored, and failing
because /proc/xen/xsd_kva does not exist.
bronwen-[~] root 18 #ls /proc/xen
balloon  capabilities  privcmd  xenbus  xsd_kva  xsd_port

maybe something isn't loaded that needs to be?

Comment 3 Michael Richardson 2006-05-18 15:10:19 EDT
uhm, not /proc/xen/xsd_kva exists on machine bronwen.
It does not on machine trout:

trout-[/etc] root 52 #ls /proc/xen
balloon  capabilities  privcmd  xenbus  xsd_mfn  xsd_port

trout-[/etc] root 53 #uname -a

Can you reproduce this with 2118_FC5 from updates-testing or does this fix it?

Comment 7 Michael Richardson 2006-05-18 16:19:55 EDT
Yes, 2118_FC5 seems to solve the problem.
