They are *gentoo* vms though, and have to do things non-gentoo hosts |
43 |
don't have to do. Like build gcc for example, and run portage. |

Both of those beasts are memory-hungry. Without them, they would |
46 |
probably run just fine on 64M but I haven't bothered trying - the host |
47 |
has 16G and even with every VM running they still us less than a third |
48 |
of all memory |

I sometimes shake my head and wonder about current RAM usage. I'm old |
51 |
enough to remember programming a Sinclair Mk XIV with 256 bytes of RAM. |
52 |
An upgrade to 512 bytes was a significant and rather expensive upgrade :-) |
