Hello!
I've an VPS which worked since a few month... since today i always receive: "Unable to open pty: No such file or directory"
I've also reinstalled the ubuntu template but it does not work always the same failure.
The funny thing is - if i create a new VPS the template works.
Kernel: 2.6.18 028test007.1
vzctl: 3.0.13-1

I don't understand, what do you mean under:

I've also reinstalled the ubuntu template but it does not work always the same failure.
|
OpenVZ template is used only when VE is created. After VE is created, external package management operates with VE, not it's template.

Above states, that template was not updated, while VE was.
So, I think the issue is that you updated udev in VE and this udev version doesn't work over our kernel.
So, please, could you check is it true? Just check two udev versions, in broken VE and in a new one.

`vzctl destroy VEID` should completely remove VE-related files, so, the followed `vzctl create VEID --ostemplate ...` should be equal to the creation of new one. I'm wonder, how is it possible to have issues in the first case and don't have them in the second.
So, I recommend you to destroy erroneous VE and check, do you have it's ID somewhere in /proc/mounts, /proc/user_beancounters or on the filesystem.

Ubuntu 8.04
vzctl exec VEID /sbin/MAKEDEV pty
vzctl exec VEID /sbin/MAKEDEV tty
theese commands make links to devices on / directory instead of /dev/
may be
vzctl exec VEID /sbin/MAKEDEV /dev/pty
vzctl exec VEID /sbin/MAKEDEV /dev/tty
?
On our installation we successfully fixed this error simply by executing
apt-get remove --purge udev
without creating any device by MAKEDEV.
What is the purpose of tihs package inside VE?

Here's the Fix:
vzctl exec VEID /sbin/MAKEDEV pty
vzctl exec VEID /sbin/MAKEDEV tty
vzctl enter VEID
|
It`s don`t work in ubuntu
Ubuntu 9.04
vzctl exec 3333 '/sbin/MAKEDEV /pty'
/sbin/MAKEDEV: warning: can't read /proc/devices
/sbin/MAKEDEV: don't know how to make device "/pty"

FIX
vzctl exec 3333 'dpkg --force-depends --purge udev'
After entering in VE for resolve depends you may install udev and disable boot scripts in sysv - udev & udev-finish.

i had similar problem. run the following commands on host node
you need to replace only <CTID> with the container id and make the .../etc/devices and .../dev if the don't exit
if your virtual machines are installed in /vz/privae/
/sbin/MAKEDEV -d /vz/private/<CTID>/dev -x {p,t}ty{a,p}{0,1,2,3,4,5,6,7,8,9,a,b,c,d,e,f} console core full kmem kmsg mem null port ptmx random urandom zero ram0
/sbin/MAKEDEV -d /vz/private/<CTID>/etc/devices -x {p,t}ty{a,p}{0,1,2,3,4,5,6,7,8,9,a,b,c,d,e,f} console core full kmem kmsg mem null port ptmx random urandom zero ram0
but if your virtual machines are installed in /var/lib/vz/privae/
/sbin/MAKEDEV -d /var/lib/vz/private/<CTID>/dev -x {p,t}ty{a,p}{0,1,2,3,4,5,6,7,8,9,a,b,c,d,e,f} console core full kmem kmsg mem null port ptmx random urandom zero ram0
/sbin/MAKEDEV -d /var/lib/vz/private/<CTID>/etc/devices -x {p,t}ty{a,p}{0,1,2,3,4,5,6,7,8,9,a,b,c,d,e,f} console core full kmem kmsg mem null port ptmx random urandom zero ram0
let me know if it works for you. it worked for me

I ran into the pty problem when I tried to create a container from a template that I had created from a git repository, using git export. I wanted to use git to keep track of my unpacked templates, but apparently git does not handle device files. So I recreated my template using tar on my stopped template container, and I was able to use it to create other containers.
