Subject: [alpine-devel] Xen-guest-only kernel configs?

Congrats to Natanael and everyone else who helped get 2.6 into shape!

I've got Alpine installed as a Xen guest on a Linode instance. To do
this, I built my own stripped-down Xen-guest-only kernels. (The x86_64
linux-grsec also worked, but the x86 one doesn't have Xen stuff turned
on. I didn't try Alpine's linux-xen package, which is intended for Xen
hosting, and so enables stuff I didn't need/want on my guest instances).

If anyone else is interested in these stripped-down kernel configs,
perhaps we could make an additional kernel package. Or I could at least
post the current version in a gist for others to lookup if they ever
have the need down the road (and stumble across this email).

They're here: https://gist.github.com/dubiousjim/5538673. That's
currently for 3.8.11, but I have versions for kernel 3.9.2, too. I'll
update the gist files sometime soon.

Thanks!

Yes, to support older hw. (if you have really acient hw, what distro
would you pick?)

Yes, I am interested, but I'd like a kernel for a generic virtual guest
that works for xen, kvm, virtualbox, vmware and hyper-v. We have the
linux-virt-grsec kernel for this purpose
http://git.alpinelinux.org/cgit/aports/tree/testing/linux-virt-grsec

Unfortunally, it is lagging behind. If you use it and plan to maintain
it anyways... maybe you could help us maintain it?

I would be ok to start over with your config and then add other virtual
drivers on request.

Ok, that makes a lot of sense. I hadn't grokked what that kernel package
was for. When I get a chance, I'll work on merging my configs and the
configs from that existing package.

I just pushed today testing/linux-virt-3.9.3.
I tested that booted in qemu, and it worked. If there's something
missing/broken, please just let me know.

Thanks!

And 2 days ago I upgraded it to 3.9.4 -- everything works so far under
Xen and KVM. Is anyone against moving it to main?

We don't have an official maintainer yet iirc. I don't ncopa is keen on
maintaining it. I can help with maintaining it, but I'd welcome an
hand :)

I didn't test it extensively, but I don't have objection in moving it to
main if we have maintainer(s).

Just tested under my KVM VPS and it hangs at this:

"rtc_cmos 00:00: setting system clock to 2013-06-02 12:26:31 UTC
(1370175991)"

I think we should disable this option:

CONFIG_GENERIC_CMOS_UPDATE=y

I'll build a new release with above option disabled tm.
