Re: [Xen-users] Fedora 12 xen 4.0.0

i've done some debugging to /usr/sbin/xend and this is what i came up with:

from  /var/log/xen/xend.log:
[2010-04-15 10:50:16 32442] ERROR (SrvDaemon:356) Exception starting

ExpatError: no element found: line 1, column 0

the file which it's trying to parse is /var/lib/xend/state/host.xml,
which is empty.
which service/module creates this xml file?  do i need to edit it?

thanks!
