:-) They are *gentoo* vms though, and have to do things non-gentoo hosts don't have to do. Like build gcc for example, and run portage. Both of those beasts are memory-hungry. Without them, they would probably run just fine on 64M but I haven't bothered trying - the host has 16G and even with every VM running they still us less than a third of all memory I sometimes shake my head and wonder about current RAM usage. I'm old enough to remember programming a Sinclair Mk XIV with 256 bytes of RAM. An upgrade to 512 bytes was a significant and rather expensive upgrade :-) -- Alan McKinnon alan.mckin...@gmail.com
