To aid testing things under Xen it helps to have a machine locally that actually runs Xen! This isn't a particularly great setup but it works well enough to simplify my own testing. Must be used with a developer image and packages built with `USE=vm-testing` set to include the Xen userspace tools.

QEMU wrapper script for a VM that is compatible with Xen:
|
|
- No x2apic, everything APIC related breaks when it is on.
|
|
- No virtio, simply does not work whatsoever under Xen.
|
|
|
|
Any arguments after -p will be passed through to qemu, -- may be
|
|
used as an explicit separator. See the qemu(1) man page for more details.
