hmm... Xen on a mobile phone or PDA? Cool! One DomU runs WinCE, another DomU 
runs Simbian OS, etc. And finally there's a way to encapsulate the Bluetooth 
stack. Past 23C3 we know about the security flaws in the protocol itself. :-)

It seems like an interesting thing to do?

Does ARM support the ring security levels? or VMX?!?
How are you going to do it?

You must modify the embedded OS, but will it give you real security?

Not at all. No time for this. Sorry.
I just thought "loud" about a "Xen on ARM" port.

Depends on design, implementation and on how secure the OS itself is.

RE: dom0 issues with switching from X to console orstarting X

[Dugger, Donald D]

Jan-

If you are running fully virtualized guests then Jun Nakajima fixed a
problem that was put into the Xen unstable tree this morning that was
probably affecting you.  The page table entry for page 0 was getting
corrupted after the first fully virtualized guest ran, causing problems
for X.  I'd try the latest Xen unstable tree and see if that fixes your
problem.

RE: dom0 issues with switching from X to console orstarting X

[Jan Beulich]

No - as said in the original description, we see this with solely running dom0. Jan

Xen on ARM

[Philip Reames]

Hey all,
    I was wondering if anyone out there knew of any work to port Xen to ARM? 
Has there been anything done on this so far?

Thanks,
Philip Reames
