Thread: Problems using XEN on FC6
Problems using XEN on FC6
user name
 2006-10-29 12:51:24 
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.

--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

Which will show us the actual live virtual hardware

running with

Dan.
