I run in this problem today.
I hope the above helps you.
Thanks for your reply. Interestingly, the file /var/log/xen/console doesn't exist on my machine. There is no any file or directory called /etc/default/xen*. So how did you address the similar problem? Could you please be a bit specific? Do I need to generate these files manually? Or How can I generate these files automatically? Is this issue caused by these missing files?

domain is to be called "f13" I would have expected a Fedora mirror to be
listed rather than the CentOS 5 mirror. Is this normal?
Do you know if this command will create a PV or an HVM guest?
If this is an HVM domain then it is possible that it simply doesn't have
a text console which you can connect to with xl console. The "Could not
read tty from store" message is often indicative of this.
It appears you have configured VNC for this domain, have you tried
connecting a vncviewer to port 5901 on the host? e.g. vncviewer
localhost:1 or localhost::5091 (check the vncviewer manpage, I'm not
sure of the syntax). Perhaps virt-* includes a command to do this for
If you want a text console from an HVM guest then you can do the
virt-install equivalent of adding
series = 'pty'
that with virt-install though.
If this is a PV guest then I have no idea what might be wrong.
