[Xen-users] Contending RAM

[Andy Davidson <andy@xxxxxxxxxxxx>]

Hi, guys --

We make fairly extensive use of Xen on our QA and testing platform.   
We like to pseudo-physically separate apache instances running  
different release candidates of our software.
This works well.  However, we could do with more ram in our 'child'  
virtual machines.
We have 4GB on each host computer.  We like to install 10 or so  
virtual machines on each host.  This leaves each VM very resource  
starved.  Since we only tend to hit environments on an ad-hoc basis,  
we need the vms available, but a lot of resources get wasted as they  
tend to be hit one after the other.
Ideally, we'd like to content system ram - so each machine is  
configured to have 1GB available.  This obviously means we need to  
contend memory .. probably 3:1 (including the requirements of the  
Dom-0). Is this possible ?
cheers

(sample config file from oru setup below)

kernel = "/boot/vmlinuz-2.6.12.6-xenU"
memory = 256
name = "qa01"
vif = [ 'ip=10.22.22.101' ]
disk = ['file:/vm/p1/qa01.img,hda1,w','file:/vm/p1/qa01.swap,hda2,w']
netmask="255.255.254.0"
gateway="10.0.12.1"
root = "/dev/hda1"
extra = "4"
