[Xen-users] Xen 3 segfaults in CentOS5

["Joris (Ideeel)" <joris@xxxxxxxxx>]

Hi list

I'm really sorry if this is an obvious question, but I just can't find  
any good google pointers anywhere. I'm running a fresh CentOS 5 and  
Xen (xen-3.0.3-41.el5) used to work OK. After deleting one guest xend  
refuses to start and segfaults... I'm extrmely grateful if anyone can  
point me in the right direction.
Below are the log outputs. I have a strace output too but it's quite a  
few lines...
Thanks
Joris
