I suspect this isn't a problem with the config of VM 2. Just
to check this, please can you start VM 2 first (using the
exact same command line above), before starting VM 1. BTW: If
the two VMs are similar, you might want to have a single shared
config file and use vmid to setup the appropriate IP addresses

Unfortunately, xen 1.2 doesn't give very useful error messages if
something goes wrong in domain creation. The 1.3 (unstable) tree
is rather better in this respect. One obvious question is how
much memory has the machine got? Dom0 will be consuming memory,
as will Xen itself. What does xc_physinfo.py show?
