I'd like to see some indication though other than "seems reasonable" as to what the value should be. For instance, if a Fedora 12 install doesn't work without 256M, that's a solid argument to bump the allocation. Short term, I'd like to see this globally configurable. >> > I keep a patch in the SUSE version for quite some time now that bumps the default to 384 for qemu-kvm. That was the first "round" number where an openSUSE installation worked. > If someone works up a patch and tests at least a couple types of guests to confirm that they all install with that number, I'd be happy to apply it (although we need some trickery to support older pc versions).
