Problems using XEN on FC6

[Jamie Burns]

Hello,

I am having problems using XEN on FC6.

I have installed a fresh FC6 machine from the DVD, only running "yum 
update -y" after the install.

I have attempted to start a DomU install but it just won't work.

====================================================

# xenguest-install --debug --file /dev/sda4 --location 
http://10.0.0.101/FC6 --name export1 --nographics --paravirt --ram 256

Domain installation still in progress.  You can reconnect
to the console to complete the installation process.

====================================================

And attempting to connect to the console displays:

====================================================

# xm console export1
xenconsole: Could not read tty from store: No such file or directory

====================================================

Why will it not allow me to install?

Jamie.

For some reason xenstored is missing the data specifiying what
Psuedo TTY the guest console is on. The /var/log/xen/xend-*.log
files may contain useful information.

This is good - the neccessary Xen daemons are all running at least.

The guest you created appears to have started up too - so for some reason
just the console is messed up. Can you also post the output of

virsh dumpxml export1
