[root@ndws00 ~]# rpm -qa "xen"
[root@ndws00 ~]# uname -a

Comment 5 Miroslav Rezanina 2011-01-18 01:23:21 EST
Thanks...just to output of rpm -qa..It should be rpm -qa "xen*" (with star to list all xen packages). Anyway, I see no problem from xen perspective. Reassign to yum to check what's wrong.
Comment 6 James Antill 2011-01-18 09:30:47 EST
Actually run these commands instead:

rpm -Va --nofiles --nodigest
yum list 'xen*'
Comment 7 Geoff Quelch 2011-01-19 12:46:24 EST
[root@ndws00 ~]# rpm -Va --nofiles --nodigest
Unsatisfied dependencies for xen-3.0.3-80.el5.i386: xen-libs = 3.0.3-80.el5

Comment 8 James Antill 2011-01-19 14:50:27 EST
Right, fix the pre-existing problems in the rpmdb and yum will be happy (yum assumes that the rpmdb is good before depsolving, rpm doesn't so much).
Comment 9 Geoff Quelch 2011-01-19 15:45:16 EST
OK, so what's wrong with the rpmdb and how do I fix it?
Comment 10 James Antill 2011-01-19 16:11:37 EST
You have a package already installed "xen" which has a requirement "xen-libs = 3.0.3-80.el5" which isn't met. This shouldn't be possible.

You could "yum remove xen" (or rpm -e xen), or try:

yum install "xen-libs = 3.0.3-80.el5"

...after the rpmdb is fixed, yum should work fine.
Comment 11 Geoff Quelch 2011-01-19 16:34:15 EST
Since we don't use xen, I simply removed the xen packages and dependencies.
Re-running the yum update seems to be working fine now.

Many thanks for your help.
