RE: [Xen-devel] Kernel BUG atarch/x86_64/mm/../../i386/mm/hypervisor.c:1

Update:
When running on 4GB of total memory instead of 12GB, everything is just
fine. (the three virtual machines, Dom0 + 2 x DomU are assigned 1GB of
memory each, in both test runs). Does that help?
If you have any ideas where I should do more debugging, please tell me.
We would really like to get this machine going.
