That's great.
I've had 3.0-unstable debs prepared for awhile now; hadn't uploaded them, for
several reasons:
1) xen-unstable required a 2.6.12 base kernel; this no longer exists in
debian, so it wasn't possible for me to build-depend on it, so I could
create a standard unified-diff.
My fix for that, is to encapsulate the mkbuildtree logic into the
kernel-package patch system, and not use a unified-diff at kernel compile
time. I've got the apply script done, but not the unpatch
script(basically, the script looks into the tar, notes all modified and new
files, saves them into debian/, and then during unpatch restores things).
2) vif-route.sh is buggy; it doesn't handle the case where multiple adapters
exist. So, dom0_ip(and the functions it calls) ends up returning 2 ip
addresses, which makes ifconfig complain.
I've got a fix hot-patched on our deployed server, I'll be sending that
soon.
3) It appeared that when I tried the final 3.0.0 release, that xenstored was
very sick. I had a previous(20051116 snapshot) installed, and the tdb file
was corrupted(sorta). xenstore-list / shows to local paths, but no vm nor
tools. Removing the file 'fixed' this. I'm not certain exactly what
happend, tho.
4) I currently have 11 separate patches. Most are not debian-specific. I'll
send those soon as well, but acceptance is not required before I upload.
Here's the directory listing; some may be able to take a guess as to what
each patch does.
5) I see it's not possible to have both a xen microkernel that supports both
pae and non-pae. For individuals who are compiling themselves, that's
fine; they can select which they want.
However, for debian, I need to provide versions of xen compiled for both.
The build system doesn't make that as easy as I like. However, I'll fix it
one way or another, even if I brute-force copy the entire directory.
Also, what other options are available, that would require multiple
compiles? Also, I don't see a concise list of what config options I can
tweak for xen itself; the documentation is a bit poor in that regard(pae
isn't even mentioned in the documentation; you have to read a separate
README).
6) This isn't a big problem, and I'll probably just punt on it(by having the
xen3 debs conflict with the xen2 debs as appropriate), but it's not
possible to install xen2 and xen3 support code at the same time. All of
the c binaries, and python scripts could be made to look in versioned
locations; however, the python modules are the problem. It'd be really
nice if instead of placing themselves in a xen directory, they were in a
xen2 or xen3 directory.
I won't be doing much of any of the work above today. I only had 3 hours
sleep last night(had to rush-deploy the xen3 server we were preparing, so we
could migrate a broken real machine to xen). However, this weekend will see
me upload to debian itself. I'll also be attempting to make the deb work on
amd64 and ia64, doing test compiles on debian's machines first.
