This week is a special week for the Drupal community and I’m very excited to be able to attend DrupalCon 2011 in Chicago.
My employer, Promet Solutions, is one of the gold sponsors for DrupalCon and we will have many cool activities for this week prepared for this event. Last year DrupalCon 2010 San Francisco was a great event and I’m sure this one will be even better. So if you are in Chicago and coming to DrupalCon, please come by and say hi; I would love to meet you and talk about cool Drupal projects. I will also try to setup a BOF on automating Drupal installations and configurations with opscode chef, and this will be based on my chef drupal cookbook.

After installing a clean Debian Lenny Xen system using xen-tools, I received this strange error when trying to connect using ssh to the machine:
PTY allocation request failed on channel 0
stdin: is not a tty

It looks like for some reason, xen-tools didn’t install the udev package. So in order to fix this issue, I had to connect (using the virtual console) to the xen machine:
xen console 1
and install udev:
apt-get install udev
strange enough the /dev/pts mount entry was present in /etc/fstab so all I had to do was to remount it with:
mount -a
(if you don’t have this entry make sure to add it in /etc/fstab:
devpts /dev/pts devpts rw,noexec,nosuid,gid=5,mode=620 0 0
and if the folder /dev/pts doesn’t exist create it first and after that mount -a).

This should fix the ssh problem and you should now be able to ssh into the xen machine. Next to see if this is fixed in xen-tools in Squeeze, and if not to file a bug for it.
