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

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).
We should avoid changing defaults. I don't think in this case it
matters, since everyone specifies -m anyway, but as a general rule
changing defaults = breakage for the unwary. At least make the default
part of the machine type to preserve compatibility.
In that case, Alex, where can I find your +384M patch, because I'd like
to carry the same one in Ubuntu...
It's all in the openSUSE build service. The direct access URL (login required FWIW) is here:
https://build.opensuse.org/package/view_file?file=kvm-qemu-default-memsize.patch&package=kvm&project=Virtualization
It merely changes DEFAULT_RAM_SIZE in vl.c from 128 to 384 for the "kvm" package.
We should attempt to do three things with default ram size:
1) bump it up to a more reasonable number
2) make it specified in the global default config
3) make sure we can provide compatibility support for older machine types
