[-- Attachment #1.1: Type: text/plain, Size: 382 bytes --]

hello all!

are you interested in port xen-4.1 to illumos(OpenSolaris) based platform?
I have found old Sun works with xen-3.4.2 and updated it to xen-3.4.4

I'll try to port xen-4.1.

can I file a bugs with issues on solaris based platform?
where can I file a bugs - I have bout some issues and I'd like to provide
fixes for solaris.

Nice to hear you're working on Xen on Illumos! 

Does the Illumos kernel still run as dom0 properly?

I think you should follow the usual Xen development workflow; post patches
against xen-unstable, and when those patches are merged to xen-unstable, 
they can be considered for backports to stable branches (4.2, 4.1).

Thanks!

[Igor Kozhukhov]

Hello Pasi,

Yes - illumos is working as dom0 - I have tested it on my illumos based
platform - http://www.dilos.org.
I have tested with xen-3.4.4.

I have installed and started CentOS 5.8 as guest, and original DilOS iso -
paravirt.

I have problems with Debian 6, but I think it is scripting problem with
grub2 - with pygrub.

I hope xen-4.1 will be better.

Could you please point me to the Xen development workflow - where can I
find how to do it ?
I'll try to learn and contribute.

Yep, Xen 3.4 doesn't have pygrub grub2 support. Xen 4.1.3 (and later versions) do have it.

It will.

Just use mercurial to fetch xen-unstable:
hg clone http://xenbits.xen.org/xen-unstable.hg

To send/submit patches against xen-unstable:
http://wiki.xen.org/wiki/Submitting_Xen_Patches

Also if you want, you can write documentation about Xen+Illumos on wiki.xen.org.
Hopefully that helps,

I'm interested specifically in HVM domU support. I'm using NCP3 on a 
minimal Debian 6.0 dom0 (with a kernel from XCP 1.5 and the Debian 6.0 
version of Xen 4.0.1 with patches to qemu-dm to support custom graphics 
and input servers for desktop use), but would like to update to both a 
newer Solaris distribution and a newer Xen version. NCP3 hangs on boot 
on any versions of Xen newer than 4.0.1 that I tried (even on 4.0.1, the 
kernel needs to be patched ), and illumos hangs on boot on all the Xen 
versions that I tried. These hangs are related to the PVHVM drivers (the 
install systems run OK, and they don't include them). Right now, I am 
trying to debug the problem with NCP3 and then will move onto illumos 
(I'm not sure if the problem is the same or not; illumos hangs sooner in 
the boot process than NCP3).

I thought opensolaris (and derivatives) runs well as PV domU? What do
you use HVM for?

Also, doesn't illumos support KVM? If you need full virtualization
with *solaris, wouldn't it be easier for that particular purpose to
try KVM instead?

For some workloads it makes sense to use HVM (PVHVM). 
So the kernel bugs/issues in Illumos should be ironed out..

It's great to know there's still interest for Xen on the Solaris platform!

Please work against xen-unstable, it will be much more easier to
upstream the changes and get Solaris support in newer versions.

If the Solaris kernel is still working as Dom0/DomU, there's probably
not much work, you will have to look at the tools side, and check that
the remaining Solaris pieces are still working, and probably add new
ones, for example libxl currently doesn't have any kind of Solaris
support, but I see that libxc seems to have support for Solaris (don't
have any idea if that's in working condition).

Mmmmmh... KVM lacks AMD support :(

Oh, and please post the current patches against Xen 3.4.4,
it'd be interesting to take a look at the patches to see how much changes
are needed for Illumos/Opensolaris.

I assume these are the ex. Sun/OpenSolaris XVM bits, that Oracle discontinued?

Re: xen on illumos(OpenSolaris) based platform

[Igor Kozhukhov]

NCP3 have old kernel - ON134 build.

DilOS based on illumos.

But these systems have Debian package manager - dpkg+apt.

I have updates for DPKG+APT for DilOS - added '-R' flag for more friendly
with IPS, added zones support.

We can install new packages to another root.

Example:
apt-get -R /<mount> install pkg [pkg1 pkg2 pkg3]

IPS:
pkg -R /<mount> install pkg [pkg1 pkg2 pkg3]

And I have updates for solaris zones.

New DilOS 1.1a2 will have packages with xen-3.4.4 and will be released Sep
18.
If you want - you can try.

Re: xen on illumos(OpenSolaris) based platform

[Igor Kozhukhov]

About KVM - you need to have EPT support CPU - I have no it.

Driver for KVM without EPT support have coredumps and need more works for
stable.

OpenIndiana(OpenSolaris fork) have xen-3.4.2 with solaris patches - but
have no builds for it.

I have found sources on opensolaris.org site, port it to userland build
system, and try to upgrade to xen-3.4.4.

DilOS contain packages with KVM drivers and you can try to use it.

I'm interested in XEN on DilOS.

Re: xen on illumos(OpenSolaris) based platform

About patches - I'll try to post, but I have dilos-userland on bitbucket
and if you are interested in it please send me your account on
bitbucket(free registration) - I'll add you to the dilos-userland-review
repo - it's free registration.

Or you can send email through bitbucket form to account 'dilos'

I'm working on xen-4.1.

As I know Oracle have no interest to xVM, because it have another
virtualization.

Btw Xen 3.4.4 doesn't have the latest security updates, just so you know..
Also they seem to be missing from 3.4 branch: http://xenbits.xen.org/hg/xen-3.4-testing.hg/

Keith Coleman (cc) is maintaining the "old" Xen 3.4 tree.

Re: xen on illumos(OpenSolaris) based platform

[Igor Kozhukhov]

Thanks for your info.

I'd like to see xen-4.1.3 port on DilOS :)

But - I have some problems with libxl ...

I'm working on build xen-4.1.3 by gcc44(with patches for illumos builds)
on DilOS build env.

Will se what I'll have.

I also have problems with build hvmloader with acpi - I have no acpica
compiler ... - I'll try to port it too for xen build.

Can I disable libel now ? Or I need it for next build steps ?

libxl has seen major changes in upcoming release (4.2), which I think
will be interesting for Solaris, and will make the port easier. Also
xend has been deprecated, so you should aim at porting libxl to Solaris.
I've been working on porting libxl to NetBSD, so if you need I can help
you on that.

You can disable libxl and use xend instead, but as I said above xend is
deprecated and libxl (xl) is going to replace it.

Re: xen on illumos(OpenSolaris) based platform

[Igor Kozhukhov]

Roger,

Thanks for your update.
Yes - I have questions with libxl and we can talk about it.

I'll try disable it for xen-4.1.3 and use xend - the same with xen-3.4.4 -
I have scripts for it.
