It doesn't, but under circumstances this is escaping the sandbox and 
generating an access violation.
This was initially reported for 3.3.1 as gentoo bug and fixed with this 
patch. Now I'm trying to get the live ebuilds working but patching is 
not an option there...
Details are available here:
http://bugs.gentoo.org/262124

Not really sure if this only manifests itself in the gentoo build 
environment, but since other places in xen-setup check for the existence 
of the file before doing sth with it, I don't think it would hurt to apply.

Btw, the path in my patch was wrong, I guess it should be 
qemu-xen-unstable instead of ioemu-dir.

Best regards,
  Christian
