Re: [uml-devel] "Couldn't grant pty"
Now that I have been able to run the Debiam 32 bit root_fs, I have returned to
the network related crashing.
This is by way of a status update, I will do more to tie down what is required
to demonstrate the problem as simply as possible.
However:
root@DEB1-32:~# rsync --archive --progress 10.0.10.30:/var/imap/ /var/imap/
The authenticity of host '10.0.10.30 (10.0.10.30)' can't be established.
RSA key fingerprint is ce:e4:0d:88:c0:07:01:8d:10:f8:91:52:b5:4b:e1:53.
Are you sure you want to continue connecting (yes/no)? yes
Warning: Permanently added '10.0.10.30' (RSA) to the list of known hosts.

This is what happened on the Debian 32 bit system with the 3.8.0-rc3 UML
kernel.
The DEB1 UML is now completely dead and locked up, no further messages escaped
after this point.
If I try to kick it with uml_mconsole:
bash-4.1# uml_mconsole DEB1
(DEB1) halt
and nothing more happens.
10.0.10.30 is another 32 bit UML.
DEB1-32 is the Debian UML, with an IP address of 10.0.10.31.
Networking is via mcast.
This behaviour is consistent with what I have found all along.
I have seen the same on a 32 bit UML running on a genuinely 32 bit machine
that is remote to my current location and which I access via the Internet, so
the problem arises using real ethernet (via tun-tap) as well as mcast; and in
a genuine 32 bit environment.
I will try to characterise this more fully, and simplify the method of causing
failure as much as possible.
I still believe that there is a real problem here, not just me doing something
stupid.

David
