This has been known to happen when dom0 is initially allocated all free memory 
and then shrunk by a substantial amount using xm mem-set in order to make 
space for domUs.

You may well find that you can fix it by moving to a static allocation of 
memory for dom0.

Alter /etc/xen/xend-config.sxp to set dom0-min-mem to 0 (this disables 
automatic resizing of dom0 by Xend).  Edit /boot/grub/menu.lst and add 
dom0_mem=256M (or whatever size you want) to Xen's commandline.

Reboot and enjoy.  I've known this fix the problem for others on similar 
versions of Xen, so I'm quite hopeful that this will solve your problem.  
Please complain at us if it doesn't!


Dave: Just a question. What use is a unicyle with no seat?  And no pedals!
Mark: To answer a question with a question: What use is a skateboard?
Dave: Skateboards have wheels.
Mark: My wheel has a wheel!
