It seems there is some kernel module missing, maybe this thread https://bugzilla.redhat.com/show_bug.cgi?id=540289
can help fix it.


Reproducible: Always

Steps to Reproduce:
1. have a XenServer VM with openSUSE 11.2
2. have a disk with a VG having one LV and some free space in the VG
3. lvcreate -s -Ay -c 64k -n dbsnap -L 4G -v /dev/existing_vg/existing_lv
Actual Results:  
displays warning
db-dbsnap: event registration failed: 17261:3 libdevmapper-event-lvm2snapshot.so.2.02 dlopen failed: /lib64/libdevmapper-event-lvm2snapshot.so.2.02: undefined symbol: lvm2_run
db/snapshot0: snapshot segment monitoring function failed.


Expected Results:  
no warning :-)
