Re: [Xen-devel] Really really small xen0

Rather than have to carry python and all the rest of the toolset, would
it be possible to:
1) Save a pre-built configuration database to send to xen
and/or
2) Save a recording of the control message traffic between dom0 and the
other domains using a BIG xen0, store the recording in an initrd and
then replay it back at startup time? (and log any errors somewhere!!)
It would be nice not to have to carry any shared libraries...
I am doing the following for my self-migration stuff:
- Building my own domain creation etc tools using straight libxc. All
statically linked. Now I can instantiate a new domain in 0.017s.
- Sticking with Xen 1.3 which has all the drivers in ring 0, until xend
is either massively simplified or rewritten in C. The old way of
handling networking was much easier for what I am doing.
- Writing my own unprived mini-os, running the tiny UIP TCP-stack, to
receive incoming migrations, so that ultimately I can remove dom0
completely. Almost there now, at least I can ping the thing now.
