Scalable VMs are an interesting idea, but for a typical session > how much RAM are we talking about? If you look at some contemporary VM hosting providers, like e.g.: http://bloggerkhan.com/vps-hosting-vps-servers/185 You'll see that most of them are in the 384-1024 meg of ram range, and almost none are larger than 4 gigs. I'm sure most of these run 32bit images, but the hosts are likely 64bit, so it seems to make quite some sense to use an x32 ABI here. -- devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/devel
