Yeah, that's a bug in libvirt - we failed to tear down the 'still born'
domain when something goes wrong during creation.

Sounds like a bug in Xen ia64 to me - the <currentMemory> is used to set
the initial boot RAM, while the <memory> tag is used to set the maximum
reservation. If you omit <currentMemory> then both will be set to the same
value. It sounds like Xen ia64 is not able to cope with the memory < maxmem
situation.
memory=200
maxmem=500

No - we don't do much (any) testing on ia64 due to lack of any suitable
hardware for testing, so we pretty much rely on community/vendors to
identify ia64 problems.

See if you can reproduce it with a regular Xen config file using config
options like
memory=200
maxmem=500
Which should simlute presece of '<currentMemory>' element. If you can
reproduce it there, its a Xen bug.
