[Xen-devel] current Xen3 (446aa56ca4fe) unable to reboot XenU ("cannot allocate memory")



Per subject. Funny thing is that this machine has *lots* of memory (it's a 16GB x86_64 system, dom0-min-mem is set to 256, and there's only one other domU running -- and that one is also limited to 64MB).

I can recreate the domain myself after it's shut down -- it's just that xend isn't restarting it as it should.
