Xen0/Dom0 is the "host" if you like, and XenU/DomU is the "child".
You are asking if I can run a UML child on the Xen0? I have not tried
it, and I'd have to mess around a bit to do so, but I can try.

I think you mean -T?
I ran:
strace -f -o /tmp/east.trace -T
/0i/sandboxes/UMLPOOL/260ocf/umlbuild/swan26/linux
initrd=/0i/sandboxes/UMLPOOL/260ocf/umlbuild/initrd.uml
umlroot=/0i/sandboxes/UMLPOOL/260ocf/umlbuild/east/root root=/dev/ram0 rw
ssl=pty umid=east $net $UML_DEBUG_OPT $UML_east_OPT init=/linuxrc $*
It never actually boots far enough with this option to print anything.
It was a big message (11MB), so, see
http://www.sandelman.ca/tmp/xen-uml-50.txt
strace -o /tmp/east.trace -T /0i/sandboxes/UMLPOOL/260ocf/umlbuild/swan26/linux
initrd=/0i/sandboxes/UMLPOOL/260ocf/umlbuild/initrd.uml
umlroot=/0i/sandboxes/UMLPOOL/260ocf/umlbuild/east/root root=/dev/ram0 rw
ssl=pty umid=east $net $UML_DEBUG_OPT $UML_east_OPT init=/linuxrc $*
without the child tracing, it makes it as it would normally, but we get
nothing about what the child processes are doing, of course.
I guess maybe that there are problems with the VT ALARMs on the XenU...
Can we build a simpler test case for the Xen folks?
