Just for this reason, our automated scripts for installing VMs call 
virt-install with 1GB RAM and 1 CPU and then use a non-interactive virsh 
edit to set the desired values before the first boot after install.

Here is how it can be done, if you are interested:

This example resets from 1GB used during the install, to whatever was 
passed to the script as $ram.


echo -e "g/mory>1048576/s//mory>${ram}/\nw\nq\n" | env EDITOR=ed virsh 
edit $name


Good Luck!
