256 MB, 128 MB, 64 MB machines
Prior to ordering a VPS, I've been experimenting with KVM virtual machines on my PC. I can't even get a yum update to run in a 256 MB box. The minimum that works is 512 MB. Even a machine that's just been created uses about 122 MB of memory. How are you all able to use 256 MB, 128 MB, or even 64 MB boxes?
