I remember seeing the exact same thing. AFAIR if you keep destroying and
creating the VMs it will not run out of memory. It might appear to use
more memory. I take it you were using "xm top" where you saw the memory
decreasing for dom0 evertime you destroyed and created a vm?
I wouldnt worry too much about it, unless it does eat up and not release
the memory. If you set the dom0_mem in the menu.lst xm top and free will
correctly report the memory been used dom0.
Just a last note about putting dom0_mem into grub/menu.lst, when you
upgrade to a new kernel, this entry will be removed. If anyone knows how
to correctly keep this boot option between upgrades, it would be good to
know.
