[Xen-users] domUs high memory usage (FC5 -- Xen 3.0.2)



Situation:

I start up my domU's (in a console) and they seem to run at ~75MB (out of
256MB) of memory.  The only thing I have done on the VMs is to use ping to
test RTT's.  I come back to the VM's the next day and notice that all of
them are running ~256MB.  I haven't started any other services.

My environment:

dom0 -- FC5  (2.6.17-1.2157_FC5xen0, using 512MB RAM)
domUs -- FC5  (2.6.17-1.2157_FC5xen0, using 256MB RAM)
domUs HD -- 5GB, only 42% used

domU 'top' output:

Questions:
1) Any recommendations of services to check?
2) What other commands could help diagnose this? 'ps'?
3) Has anyone noticed if any services are getting started and never freed
up when finished?
4) Could dom0 be the culprit?

Thanks in advance for any help.
