Hello

How Xen  allocate memory between dom0 and domU ?
What (maths) relations are between dom0-min-mem and domU memory ?

grep memory  /etc/xen/vm01-config.sxp
memory=32


xm list
Name                              ID Mem(MiB) VCPUs State  Time(s)
Domain-0                           0       33     1 r-----    16.5

grep dom0-min-mem  /etc/xen/xend-config.sxp
# 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 16)
