Has anyone been able to boot a fully virtualized (Intel VT) 32bit guest
on XEN32 unstable? I'm trying to setup a nightly test environment for
this configuration and XEN32 nosmp hangs when launching a 32bit guest,
and XEN32 smp gets a double fault launching a 32bit guest. It happens
pretty early as the SDL window doesn't come up. I tried with apic,
pae, and acpi all on and all off, same problem. Example config attached.
Here is my XEN32 nosmp console:
