This actually may be related to the TX checksum issue.  I've confirmed that during installation I can use FTP to download distros which explains
why the installation process works "fine" but when I spawn a shell, I cannot successfully make an ssh connection to a remote host.

After installation, I confirmed that I can indeed run FTP (which is how I got the sys src to build a new kernel).  I setup telnetd and was able to login
remotely but any long output would get clobbered.

Here is the xenstore-ls -fp output you requested.  Is there anything I should provide concerning a possible link to the TX checksum bug?
