Hello.

I'm having a quite big problem with xen and I'm pretty much stuck with
it by myself, so hopefully someone can help me out with this.

Symptoms look like this:
tvsrv1:~# xm create ns1
Using config file "/etc/xen/ns1".
Error: Creating domain failed: name=ns1

And relevant parts from the xend.log:
[2010-02-02 11:35:18 4049] DEBUG (XendDomainInfo:92)

Host is Debian Lenny with 2.6.18-xen-3.4.2, built by myself. I have
another similar host (almost 1:1) which doesn't have this problem. I'm
using DRBD to distribute ns1.primary.img and domU configuration is the
same so it's not about the virtual machine itself either.

Afaik this started when I upgraded NIC driver (thank you, Broadcom) but
I can't recall any actions which could've caused this. I tried to
recomplie both the kernel and the Xen (didn't do "fresh" build, just
make distclean && make) but that didn't help.

I tried to google this and all even near relevant I found was an Debian
bugreport (http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=520641) but
as far as I can understand that's not the issue here.
