An image that comes up successfully is crash when be created with virsh:
This is libvirt create config file:

All the devices seems to be successfully started up. There is something
else going on. I suggest to check in /var/log/xen/xend.log for the two
S-Expressions given to xend between the xm launch and the virsh launch.
There must be a difference given which leads to some emulation breakage.
Guessing what a priori is not very efficient, the difference has
to be found in the logs output between both creations.

The two devices above seem to be wrong, when compared to the Xen configuration
file below. It looks like you want something like:
<devices>

If that doesn't help, please tell us how it crashes, exactly, and give the
console output from the guest (if it gets that far).

Sorry I must have copied the wrong XML configuration file. The
one I
pasted in
was an experiment to see if the problem was related to using tap:aio. It
didn't
make any difference.
Here is the right configuration file:

OK, yeah. The XENBUS: Device with no driver can be ignored, I'm pretty sure.
The problem is probably what you think, that you don't have a root=/dev/xvda1
line in there. Other people will have to comment on whether there is a libvirt
XML equivalent, since I'm just not sure.

I used virsh xmldump to create an xml file.
I comment out the bootloader element since XEN create fails with an error
when
the bootloader element is empty. Also I commented out the target dev vif
directive because
it is ignored by create. The domain id directive is also ignored.
This is a commented copy of the working xml:
<domain type='xen' id='78'> <!-- create seems to ignore id
directive -->
<name>ken-30</name>
<uuid>c309cbc4-7e95-545f-0b16-2bf9e1e050dd</uuid>
