Hello,
I make a domain on ttylinux as in the Xen 2.0 manual. Then I try to
connect to its console, but without sucess. Anybody please tell me how
to fix the problem?
Here is how I connect to console (my Xen installation is from Xen
2.0.1 binary tarball):
---
$ xm list
Name Id Mem(MB) CPU State Time(s) Console
Domain-0 0 245 0 r---- 271.4
tty 13 64 0 -b--- 0.5 9613
$ xm console tty
************ REMOTE CONSOLE: CTRL-] TO QUIT ********
Cannot connect to console 13 on domain 13
************ REMOTE CONSOLE EXITED *****************
$ xm console 13
************ REMOTE CONSOLE: CTRL-] TO QUIT ********
Cannot connect to console 13 on domain 13
************ REMOTE CONSOLE EXITED *****************
$
---
Thank you,
AQ

what does `nc localhost 9613`? in other words, are you able to connect
to the TCP port that console is bound to? does option "-c" for `xend
create` work?

ah, I forgot to tell you that the problem I got was with -c option (xm
create tty.xen -c)
here is the output of my attempt to connect to tcp socket, as suggested by Jan:
---
$ nc localhost 9602
Cannot connect to console 13 on domain 2
---
as you see, the problem still occurs.
then I tried again, this time without -c option. and I was surprised
to see that "xm console tty" works (!!).
so I conclude that this is the expected behaviour of Xen: if I want to
connect to console with "xm console", then I must not use "-c" option?
Thank you,
AQ

no. something is wrong :-). I'm not a xen developer, but I'll suggest
you to try to run xend with some debugging options...
Aren't you trying to access domain's console twice at once? I mean
console opened from "-c" option and then issuing `xend console ...`. It
shouldn't work, AFAIK.

Yes, I run "xm create tty.xen -c", and then in another console (of
domain0) I run "xm console tty" --> this time without success.
So the problem is that: at the same time there is only 1 console? any
Xen developer can confirm this?
Thank you,

I'm not a developer, but I can confirm that this is, in fact, the case.
The consoles provided as part of Xen are like serial consoles to
independent systems. They are unmultiplexed. Simply, once you have
connected to it once, that's it. If you need to connect to the instance
multiple times, perhaps you should be using SSH instead?
