Re: [Xen-devel] Support for unmodified OS

Thanks Ian for replying.

So , it seems, as my main requirement is that I can't modify the Android OS, so I am left with the only option of using full virtualization. (xVisor looks good and has been ported on ARM).

The patches needed to run on Xen on ARM went into Linux upstream around
3.7 or so. If you have a kernel newer than that with CONFIG_XEN and the
associated other items enabled then you should be good to go.

Last I saw Android was still on 3.4, so you'd either need to wait for
them to update or do some backports yourself. Even after they update
it's not obvious that they would necessarily enable CONFIG_XEN.

Caveat: I've not actually tried android on Xen in any way...

Ian.
