The configuration for dom0 and for each domU specifies exactly how much
memory it should have. I believe that it is also possible to increase
the memory allocated to a running VM.
And what are correct (at least in theory) minimal or recommended
values (xyz1,xyz2,xyz3) to be passed as parameters for:
* dom0_mem in
kernel /boot/xen-3.0.3-1-i386.gz dom0_mem=xyz1
* dom0_min_mem in /etc/xen/xend-config.sxp
# Dom0 will balloon out when needed to free memory for domU.
# dom0-min-mem is the lowest memory level (in MB) dom0 will get down to.
# If dom0-min-mem=0, dom0 will never balloon out.
(dom0-min-mem xyz2)
* memory(param) from configuration file used to create domU virtual machine(s)
/etc/xen/vm01-config.sxp
memory=xyz3
for 512 MB physical memory.
