PATCH [xenconsoled]: makes pty slave raw early
Hi,
on my system (Linux 2.6.18.8 - ia64), if a domain write on the xencons
before xenconsole is initialized the domain gets back what it wrote.
This patch fixes this issue by making raw the pty slave very early.
(I suppose it doesn''t happen with linux as a guest because it takes a little
bit of time before writing to xencons).
Tristan.

''xm create'' creates domains without a valid console tty
I''ve noticed that after I create 83 domains on a server, ''xm create''
will create domains without a valid console tty value.
This corresponds approx. to 256 file descriptors. I''ve bumped up the
limits for all daemon processes to 1500 file descriptors,
so I''m really puzzled where xen is hitting a resource limit.
