PTY allocation request failed on channel 0

by on Aug.13, 2010, under Tech Junk

When installing a new virtual machine (Lenny) you may get this error:

PTY allocation request failed on channel 0

stdin: is not a tty

To fix this do the following:

Add the following line to /etc/fstab (in the domU):

none /dev/pts devpts defaults 0 0

Then run:

mkdir /dev/pts
mount /dev/pts

Volume by UUID and adding the disk to a xen Virtual Machine

by on May.08, 2010, under Tutorials

Get the drive UUID by using the command vold_id

vol_id /dev/sda1

The string after “ID_FS_UUID=” is the UUID of the drive. Now open your /etc/fstab file and add the following line to the end. Replace the UUID string with your string, your mount point, and customize the other parameters if needed.

UUID=THE-UUID-HERE   /mnt/USBDrive   ext3   user,auto,rw   0   0

To then pass a disk to a xen virtual machine, look at the following lines of the domain config file:

disk        = [
#...root partition and other partitions here...

basically instead of passing the disk as a /dev/sda1 device, pass it by UUID using the path:

/dev/disk/by-uuid/<the uuid>

iFolder on Debian Lenny (as xen DomU)

by on Feb.05, 2010, under Tutorials

UPDATE: Simple way for me to deploy iFolder on a Debian systems was though xen and an installation of Ubuntu as follows…

NOTE: I can get everything to install and run. Problem so far is logging in as admin that does not work (seems to be a common problem with no precise solution so far)

Step 1:

Intall Debian Lenny on a clean machine (plenty of tutorials online for this!)

Step 2:

Setup Xen on the lenny installation (this tutorial is a good place to start. Ensure you are on a 64bit machine for this one. IF you are on a 32-bit machine, it is not too different)

Step 3:

Intall Ubuntu 10.04 (lucid) – Follow this tutorial with following modifications:

After installation, open the config file for the Virtual Machine and:

Comment out the “kernel” and “ramdisk” options


bootloader  = '/usr/bin/pygrub'

Make sure you invert the disk options as mentioned in the tutorial

Step 4:

Before installing iFolder run the following (all one line):

apt-get install apache2 automake autoconf libtool liblog4net-cil-dev 
mono-xsp2-base cli-common-dev uuid-dev libxml2-dev gsoap libflaim-dev 
mkdir -p /var/www/.config/.mono/
chown -R www-data:www-data /var/www/.config/
apt-get install apache2 libapache2-mod-mono

(answer Y to the question)

Configuration file `/etc/apache2/mods-available/mod_mono.conf'
 ==> File on system created by you or by a script.
 ==> File also in package provided by package maintainer.
 What would you like to do about it ?  Your options are:
 Y or I  : install the package maintainer's version
 N or O  : keep your currently-installed version
 D     : show the differences between the versions
 Z     : background this process to examine the situation
 The default action is to keep your current version.
*** mod_mono.conf (Y/I/N/O/D/Z) [default=N] ? Y

Install iFolder on the Ubuntu Virtual Machine following the official Ubuntu tutorial

Run (if needed to reconfigure admin password)

dpkg-reconfigure simias-server
