Hello peoples, I am neww here and already got a problem.
I have setup an debian 64bit minimal, installed the xen-system-2.6.26 for amd64 and with the xen-tools I was ready to go. I set up a guest by using xen-create-image and installed an etch guest. now when I start the guest by invoking "xm create vm1.cfg" and looking into "xm list", the state of vm1 is "blocked". opening the console of vm1 "xm console vm1" prints the following:

That's all. Invoking an "xm shutdown vm1" tells me that the vm1 properly changes the runlevel and cleanly shuts down.

Does some body have any idea 'bout that? Thanks!!!

I to am having this exact problem. Xen 3.2.1-amd64, Debian 5.0 Lenny (Dom0 and the DomU with the issues). SSHing into it gives me: "PTY allocation request failed on channel 0
stdin: is not a tty". Any suggestions anyone?

Edit: I got it working by uninstalling and reinstalling Xen and all its related packages. No idea why it happened, but it seems to work now *fingers crossed*.

Try to add extra parameter to your domU configuration file
extra = ‘console=hvc0 xencons=tty‘
It helps me.
