I ran into this many many times with RHEL 5 and the problem looked like a ballooning issue to me (but I am not developer-savvy enough to fix it myself). I ended up using the dom0_mem param at boot time, as was suggested in this thread, and set it to 1024M. That gives you a 1GB dom0 and should give you 7GB or so for domUs. That seemed to fix the problem for me. I also ran into a problem with trying to run more than 80 domUs simultaneously... that seemed to be a hard limit, but looked more like a network issue than a memory issue.
