No. I copied the config file in /etc/xen from a working config every 
time I created a new domU. Change names, ips, and go. Block devices for 
the different domUs are LVM-backed ext3 file systems which I created by 
unpacking a tar. Every time the same tar.
But... Some spooky shit going on here.. I did

xm shutdown wikitest
xm create wikitest -c

(wikitest is another domain, one of the 6 mentioned earlier)

It didn't come up. It behaved the same as the other domain (the 
'vechtstreek_test' domain I originally reported about). It boots fine 
with the newer kernel without SCSI-support. It started fine a couple of 
days ago using the kernel with SCSI-support built in. I'm 100% certain 
about that.
