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
