[PATCH 0/4] xen 4.3.0 recipe and updated xen-image-minimal

[PATCH 0/4] xen 4.3.0 recipe and updated xen-image-minimal

[Chris Patterson]

This set of patches should provide a user with the ability to generate a xen 4.3.0 based dom0 image.

[NOTES]

With these patches, xen-image-minimal requires "xen" and "aufs" to be present in DISTRO_FEATURES to function correctly.  

[DISTRO TESTING]

This image has been tested using:

machine=sugarbay
DISTRO_FEATURES += " aufs xen"

[BUILDING IMAGE]

bitbake xen-image-minimal

[QEMU BUILD TESTING]

To start up and test core-image-xen using kvm on hardware supporting nested virtualization:

kvm -hda deploy/images/xen-image-minimal-sugarbay.hddimg -cpu host -no-kvm-irqchip -m 4096 -net nic,model=e1000 -net user -serial stdio

..or..

kvm -hdc deploy/images/xen-image-minimal-sugarbay.iso -cpu host -no-kvm-irqchip -m 4096 -net nic,model=e1000 -net user -serial stdio

[XEN TESTING]

To test the runtime core-image-xen and boot a debian PV virtual machine:

# bring up networking
ifconfig eth0 up
brctl addbr br0
brctl addif br0 eth0
udhcpc -i br0

# place test debian vm in /test/debian
mkdir -p /test/debian
cd /test/debian

# pull example kernel, initrd
wget http://ftp.debian.org/debian/dists/wheezy/main/installer-amd64/current/images/netboot/xen/initrd.gz
wget http://ftp.debian.org/debian/dists/wheezy/main/installer-amd64/current/images/netboot/xen/vmlinuz

# create 4G disk
truncate -s 4096M disk.img

cat > debian.cfg << EOF
kernel = "/test/debian/vmlinuz"
ramdisk = "/test/debian/initrd.gz"
extra = "debian-installer/exit/always_halt=true -- console=hvc0"
vif = ['bridge=br0']
memory = "256"
name = "debian"
disk = ['file:/test/debian/disk.img,xvda,w']
EOF

xl -v create -d debian.cfg

xl console debian

Nice. The fragment looks good. I'd actually like to bump this up to the level of
in-tree support that we have for KVM.

And by that, I mean that I can merge this to the meta branch of the linux-yocto
kernel (and also found in the tracking yocto-kernel-cache repository).

Once there, it can be built and tested standalone, as well as shared by other
feature fragments. You'd then be able to just enable it via a KERNEL_FEATURES
entry, just like KVM.

Cheers,

Bruce

"Thou shalt not follow the NULL pointer, for chaos and madness await

Re: [PATCH 1/4] linux-yocto: add kernel fragment and scc for xen dom0 kernel support.

[Chris Patterson]

[-- Attachment #1: Type: text/plain, Size: 1935 bytes --]

That'd be great.  There are a couple areas that could perhaps use some
work, as the fragment is a little excessive in some of the options and/or
could be broken up a little better, if desired.  On this topic, I have a
couple questions that would help steer me in the right direction in the
future:

1) One thing that's not immediately clear for me is the question of how to
best handle a case where a CONFIG_XXX option may in one instance, be
desirable to be built in - vs being a module in another?  Doing a quick
test seems to imply the first defined instance is the one used, but I'm not
sure if there are any well defined rules for conflict resolution.  The
reason I'm asking is there are CONFIG_XXX=y instances in this config - some
of which need to be built in, some required, and some just *preferably*
built in for various use cases. Specifically CONFIG_XEN_PCIDEV_BACKEND=y
provides some useful functionality before a module could otherwise be
loaded (prevent a pci device from being owned by a linux driver).

2) The other thing I am curious about is how to negotiate the inclusion of
a KERNEL_FEATURES which has a number of built-in bits.  The approach used
by kvm is to effectively always enable the fragment if one is including
meta-virtualization.  This in and of itself isn't really polluting the
target image for those that don't want KVM, because they likely simply
don't include the built kvm modules (ignoring CONFIG_TUN=y).  However, when
you have the =y cases, the user of the layer doesn't have a choice without
going through and commenting out the KERNEL_FEATURES_append...?  This was
the reasoning I took for choosing the base_contains() functionality instead
of just including it like the other bits (ebtables, vswitch, etc.).  Is the
goal for the layer's linux-yocto bbappend to support a "generic" kernel (by
default) to support all of its packages/images?

Take care,
-Chris

It should be last through the gate that wins, which gives the fragment that
includes another one a chance to tweak and override what it doesn't like.

If you were really seeing first one being set, then something has broken and
I'll hunt it down, I never assume that something hasn't managed to break
itself, but it should still be behaving as it has before.

What you may have seen is that KERNEL_FEATURES and .scc files on a
SRC_URI are applied in a particular order. .scc files and then KERNEL_FEATURES,
so if you want to override a feature, you need to do it with another features.

So in your case, you can have that base fragment sets the requirements as
built in, that's a good start. You could then have a secondary fragment which
sets the preferable options, and more fragments that had completely optional
values. Leaving the recipes and higher level fragments to chose the mix they
want.

Alternatively, you can set them all in the single fragment like it is, and then
the including feature can always override, or from recipe space additional
features be triggered override the values.

An excellent point .. and yes, a layer shouldn't really be setting
values like this
unless it was single purpose. If we have Xen and KVM both active and available
via meta-virt, then we really don't want that.

I'd convert KVM to trigger via a IMAGE or DISTRO feature as well, just as you've
done with your fragments.

Cheers,

Bruce

I went back and double checked - you are right - last fragment wins as you
expected. I typo'd something in my test :)  Thanks for the clarification,
that makes more sense to me now.

Bruce,

I'm working on a v2 of my patches and I was curious how would you like to
handle the xen kernel fragment.

Should I go back and make a patch suitable for linux-yocto and submit
there?  Or stage for meta-virtualization and submit again (with signoff and
3.10 support)?

Thanks,
-Chris

Let's keep it simple, submit everything here, and I can do the leg work to pull
it into linux-yocto as appropriate. It'll give me a goo chance to test
things as a
side effect!

Also nice. I like the change. With my previous comment about pulling
the xen fragment into
the kernel itself, you'd be able to make these two lines consistent.

Moving up the chain to new kernels is simple after that, since I'll
pull it forward as I uprev
support. (in fact, we can also add a new 3.10 fragment along with
these changes now :)

Cheers,

Bruce

I was going to ask if you are seeing any QA warnings with this, since
in the past we've had
to use update alternatives and priority to ensure that the right init
was used in an image .. but
then I noticed this is only pulled into the minimal config and there
shouldn't be any conflicting
init providers!

Re: [PATCH 4/4] xen-image-minimal: update image to support xen 4.3.0 base with xl toolstack.

[Chris Patterson]

[-- Attachment #1: Type: text/plain, Size: 13758 bytes --]

The reasoning for xen-image-initramfs was that I had minor issues with
using stock core-image-minimal-initramfs and initramfs-live-boot.

However, I have since tracked down the issue I was having with
initramfs-live-boot, and determined we could drop initramfs-boot-xen in
favor of initramfs-live-boot simply by adding LABEL=boot to the kernel args.

Beyond that, vanilla core-image-minimal-initramfs would hang at "Waiting
for removeable media..." indefinitely.  After some testing, It appeared
that adding coreutils to core-image-minimal-initramfs would resolve the
issue (though not yet sure why, but looking into it).

Re: [PATCH 4/4] xen-image-minimal: update image to support xen 4.3.0 base with xl toolstack.

[Chris Patterson]

[-- Attachment #1: Type: text/plain, Size: 15027 bytes --]

Tracked down the issue to the busybox defconfig in the meta-virt layer.

There were patches upstreamed to udev's mount script to require 'stat' in
addition to a similar update to busybox's config to provide it.

commit ef7e1239b95dbef4e461007d6d0612c27a7919ec
Author: Andy Ross <andy.ross@windriver.com>
Date:   Tue Sep 18 14:38:44 2012 -0700
busybox: add /usr/bin/stat applet...

commit 3543d0db691e82098c1da7bf12f43e0c57551a3d
Author: Andy Ross <andy.ross@windriver.com>
Date:   Tue Sep 18 14:38:45 2012 -0700
udev-extraconf: Don't mount root filesystem under /media...

I suppose this could be resolved by updating the busybox defconfig to a
fragment turning on only the extra bits it wants?  Or should I be
prioritizing my layers differently?

Re: [PATCH 4/4] xen-image-minimal: update image to support xen 4.3.0 base with xl toolstack.

[Philip Tricca]

Chris,

Do you have a meta-virt mirror where you're staging all of this? I went
through to test and build this against the master branches of oe-core
etc and had to make a few tweaks. Figured sending changes back to you
might speed this along.

Thanks,
- Philip
