[Xen-devel] Problem booting fully virtualized (Intel VT) 32b guest on XEN32 unstable

[Ed Smith <esmith@xxxxxxxxxxxxxxx>]

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:
