Xen users - Aug 2009 - Console stops responding after init finsihes runlevel 2 startup

I have a new guest (Debian Etch) which started life as a physical 
machine. I installed a Xen kernel (2.6.26-2-xen-686) and copied the 
filesystem contents to a new volume on an existing Xen host (kernel 
2.6.18-6-xen-686 and xen-hypervisor-3.2-1-i386).

It boots and runs just fine, but as init finishes starting things up 
in runlevel 2 the console stops responding. Console output still 
works (eg kernel messages are produced when loading modules), but no 
keyboard input is accepted. I put some scripts in /etc/rc2.d that 
just did "sleep 5", and while these are sleeping, I can hit return 
and get blank lines. Immediately the last file is run, the keyboard 
stops responding.

If i startup in single user mode and manually start each service, it 
works fine.

Any suggestions where to look ?

Check /etc/inittab for a proper hvc0 getty console.

OK, that''s fixed it. But ... none of the other guests on this server 
have such an entry. Still using Debian Etch - the main difference I 
can see being that the other guests were installed from scratch as 
guests using debbootstrap while this one was installed on a real 
machine and then copied.

No idea, if they''re running the exact same kernel with the same
command line.

It''s obviously a change in defaults somewhere. I''ve just
brought up
another new box using my old template and got a console with kernel 
2.6.18-6-xen-686. Upgraded the kernel to 2.6.26-2-xen-686 and it 
needed an entry in inittab.

Exactly.  2.6.18-6-xen defaults to tty0, 2.6.26-2-xen defaults to
hvc0.  You can actually read this in changelog.Debian.gz, even.
I said I didn''t know if they used the exact same kernel.  2.6.18 and
2.6.26 do not qualify.

Hi,
I got a similar problem. The "mx console " worked well but after
pressing Ctrl + C as a mistake of trying to escape from mx console i''ve
console stopped. Even when i reboot and try to console a gain it does not do
anything.
