New to Xen - Need Help Please!

[HostBigger Admin]

Hello All:
 
I am new to Xen and have been having some problems getting it running. I had
posted on the xen-users list but they recommended that I direct my questions
to this list. So I apologize if this is misdirected. I am just trying to
find a solution to the issue I am having. I have read and followed several
tutorials and tried different fixes for this issue but have had no luck. 
 
Here is my server setup first:
 
Dual Core - Dual Processor Xeon 5120
2GB RAM
Virtualization support in bios is enabled
CentOS 5.2
No direct console access, only remote access via SSH2
 
I have used the tutorial located at http://www.howtoforge.com/centos_5.0_xen
 
Everything works up until I run virt-install to create the domU. I run
virt-install with the -nographics switch and get the following
 
No console available for domain
 
Domain installation still in progress.  You can reconnect to the console to
complete the installation process.
 
 
I then tried to connect to the console using
 
Xm console 5 
 
 
And I get:
 
xenconsole: Could not read tty from store: No such file or directory
 
I looked at the qemu log in /var/log/xen
 
And this is what I see
 
 domid: 5
 
 qemu: the number of cpus is 1
 
 *** image /local/domain/0/backend/vbd/5/768 format raw driver 
 0x80e7940
 
 *** image /local/domain/0/backend/vbd/5/5632 format raw driver 
 0x80e7940 Watching /local/domain/5/logdirty/next-active
 
 Could not initialize SDL - exiting
 
I am however unable to find any information on this error. So basically I am
in need of help in getting a domU started and running. Can someone please
give me some advice, point me in the right direction etc?
 
 
Thanks in advance

This is actually a known bug: xen doesn't abide nographics
and tries to init SDL. This will almost always fail if
run through 5.2 libvirt. This bug will be fixed in 5.3.

What you can try in the interim is specify --vnc to
the virt-install command line. This should prevent the
guest from crashing, and you can continue as normal
with 'xm console' which should just work for a PV guest.
