xend update breaks xen
Last modified: 2007-11-30 17:11:33 EST
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
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:
(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?

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?

strace -ff -o /tmp/xend$$ /usr/sbin/xend start, output. (one file)

strace -ff file, (this is the right one)
Yes, 2118_FC5 seems to solve the problem.
