The first one is my shiney almost new desktop (Dell Inspiron 660) and
the second one is my "hot backup" (more like emergency backup, 6-year-old
Dell Dimension 530). I'll be on the new machine unless it breaks. But
I do want to be able to port the QEMU VM to the older machine as part of
its "hot backup" status.
On any other distro, it wouldn't matter, but I have "-march=native" in
make.conf, so I do have to worry about keeping binaries compatable. If
I build for "Intel Core 2 Duo CPU E4600" on both machines, would I be
losing noticable performance? Right now, it's just one Windows program
that I'll be running occasionally. So I'd rather trade off a bit less
speed on the new machine, versus compatability issues. I also prefer to
be able to scp the VM disk images to the backup machine, rather than
having to do a separate install on each machine.
