[Xen-users] problems with initial xen install and domains on fc4

[Chris Kanich <ckanich@xxxxxxxxxx>]

Hi, I've been following 
http://fedoraproject.org/wiki/FedoraXenQuickstart to get a xen install 
up and running for myself. I successfully rebooted into the xen0 kernel, 
however when attempting to initialize a second domain, the bootup (xm 
create -c rawhide) stalls out while booting up, here's a snippet of the 
output leading up to the stall:
---

[root@cse-air-dhcp-128 xen]# xm create -c ./rawhide
Using config file "./rawhide".
Started domain rawhide, console on port 9611

So I ctrl+] out, and if I "xm list" once I see rawhide running, but if I 
"xm list" again, rawhide is gone. checking /var/log/xend.log and 
xend-debug.log don't show any errors, and unfortunately I'm not versed 
enough with linux to be quite sure what's going on with IPSec's 
initialization. Another bit of oddness is that I made sure SELinux was 
off in the redhat.img's /etc/selinux/config file, however I still see 
some messages regarding SELinux initializing. Any pointers or further 
questions about my setup would be greatly appreciated.
Thanks much,
Chris Kanich
