When installing new virtual machine on a Debian “Lenny” host,
You might get the following error message once you try SSH the new domU:
PTY allocation request failed on channel 0
stdin: is not a tty
One way to solve the problem is installing udev ont the host guest (in case it is not installed yet).
Log in to your Dom0 and than connect your domU’s console with xm console [domU ID]
At the domU console run:
apt-get install udev
Edit and add the following line to /etc/fstab (At the domU Console):
none /dev/pts devpts defaults 0 0execute :
mkdir /dev/pts
mount -a
Another solution can solve the missing mesg y line which you can find in /etc/bashrc or in ~/.bashrc or ~/.profile file. comment the line, and try to log in via ssh.
Now try to login.
Good Luck!
you can do this, or install udev. It also helps.
Thanks for the tip!!
It is the coolest site,keep so!
So goooooood thanks
how do I wrote that on the domU since I can’t even go into a shell in domU ??
I’ve already install udev on the domU using custom role I’ve made.
If you have access to your Dom0, than you should connect your domU console via xm console domU ID.
The problem is I can get a shell even after xm console to the domU. It’s just hang up.
Did you try adding -
extra = ‘console=hvc0 xencons=tty‘
To your domU config file?
If not, than try doing it and xm shutdown domu. and create it again with -c flag.
after add in domU config file and doing xm create domU -c it still silent after
Starting periodic command scheduler: crond.
and if I ssh to it, it still have these output :
PTY allocation request failed on channel 0
stdin: is not a tty
Thanks, it works now after I delete then create the domU again.
