Sorry to bump my own thread, but does anyone have any ideas about this?
<div><br>
</div>
<div>I've now tried virtually every combination of options in virt-manager and virt-install, and nothing seems to avoid this error (or let me get beyond the networking screen in virt-manager).</div>
<div><br>
</div>
<div>Has anyone encountered anything like this before?</div>
<div><br>
</div>
<div><br>
</div>
<div>Thanks,</div>
<div><br>

Hi there,
<div>I've been happily installing VMs in CentOS 5.2's Xen implementation using virt-manager. However, my latest attempt to use the install wizard in virt-manager failed when I got to the networking screen. The 'forward' button was unresponsive, and I was unable
to proceed. I checked the virt-manager logs, and saw this appearing immediately after I tried to proceed:</div>

<div>There was also a lot of this in the main system log (1-2 messages per second):</div>

<div>So I tried to use virt-install on the shell instead, but got much the same error:</div>

<div>It suggests I try to start the domain anyway, but it hasn't been created:</div>
