This part of the output is curious:

+ p=aio:/xenstore/xenvol1/Projects/disk0
++ xenstore_read backend/vbd/0/51952/mode
+++ xenstore-read backend/vbd/0/51952/mode
++ local v=w
++ '[' w '!=' '' ']'
++ echo w
+ mode=w
+ case $t in
+ '[' -x /etc/xen/scripts/block-tap ']'           <-------------------------??
+++ export 
+++ export LANG=POSIX
++++ set
++++ grep '^LC_'
++++ cut -d= -f1
+++ unset
+++ trap sigerr ERR
+++ log debug remove XENBUS_PATH=backend/vbd/0/51952

The marked line tests if block-tap is executable, and then suddenly jumps to 
another script, which is doing a remove.

1) Is block-tap indeed marked as executable? My SuSE 10.3 system doesn't even 
have a block-tap, so I'm not sure what package that comes from. What is the 
output of 'rpm -q --whatprovides /etc/xen/scripts/block-tap'? If you don't 
have it either, try 'yum install /etc/xen/scripts/block-tap'.

2) Can you verify what script the rest of the output after the flagged line is 
coming from?
