Xen users - Mar 2008 - how to make virtual machine in xen allocate memory automatically?

hi,
recently I installed  xen 3.0 at  centOS5.1 server with one centOS5.1
virtual machine, and I set the virtual machine allocate 2 vcpu and
minimum memory allocation is 256mb, and maximum memory allocation is
750mb. and the virtual machine running fine at idle status, and
allocated 256mb memory.
And today I install an application called dotcms, and it :
Using JAVA_OPTS: -Ddotserver=dotcms_1.5.1 -Xss2048k -Xmn100M -Xms500M
-Xmx500M ,
the application is hanged until I manually allocation 515mb memory for
this virtual server.
Why the guest os didn''t allocation available  memory itself when it
needed? How can I make it automatically?
And if I set minimum memory allocation as high as maximum, will it
affect other virtual server''s memory requirement?
Thanks!
Jimmy
