Xen users - Sep 2010 - Step-by-step tutorial: Installing Xen 4.0.1 rpms on Fedora 13 with pvops Linux 2.6.32.x dom0 kernel

Hello,

I just wrote a step-by-step tutorial how to install the latest Xen 4.0.1
hypervisor
on Fedora 13 (x86_64) host from src.rpm packages, and the pvops dom0 kernel from
git repository.

Check it out: http://wiki.xensource.com/xenwiki/Fedora13Xen4Tutorial

It also shows how to install various Xen PV guests using the native distro
installers:

	- CentOS 5.5
	- Fedora 13
	- Ubuntu 10.04 LTS

Hopefully this is helpful to someone! :)

Could you , please , explain why ?

It''s "just in case". It''s not really required. 
I prefer making sure every tool out there can read /boot partition
to avoid problems :)

Via my experience :-

title Xen 4.0.1 on F13
rootnoverify (hd1,7)
chainloader +1

might have problems with ext4.
I have not notice anything else.

pvgrub can''t handle ext4 partitions, and does so in a non-obvious way
(often by just going into a spin loop...).

There are ext4 patches in various distro grub1 packages, such as those
which inspired the patch in 20652:c6ee21dca848 to pygrub/libfsimage.

If someone were looking for a project then rebasing pvgrub onto one of
the grub1 distro patchsets which is actively maintained would be useful.

Ian.

I don''t know how is it with pvgrub but pygrub is using libfsimage where
ext2fs-lib subdirectory resides. If you''re having e2fsprogs version
that
supports ext4 (should be available in Fedora 10 and higher AFAIK) you 
should have no problem with ext4 support there.

pvgrub is native grub running as a PV stub domain, it uses the regular
grub filesystem backends not e2fsprogs or libfsimage etc.

It was written concerning Dom0 set-up  on top F13 not DomU

Well, you need to have ext4 support in your dom0''s e2fsprogs or
directly
implement in libfsimage in order to have pygrub (I don''t know how are 
the things with pvgrub) working for PV domUs that have ext4 boot 
partition and this resides always in dom0.

It''s done for e2fsprogs-devel on F13.
I should care only about :-
# yum install e2fsprogs-devel

The last is mentioned in XenWiki 4.0 in section -

Packages required to build Xen 4.0 from source on Fedora 11, 12, or 13, in
addition to all the usual development tools and libraries:
yum groupinstall "Development Libraries"
yum groupinstall "Development Tools"
yum install transfig wget texi2html libaio-devel dev86 \
 glibc-devel e2fsprogs-devel gitk mkinitrd iasl xz-devel \
 bzip2-devel pciutils-libs pciutils-devel SDL-devel \
 libX11-devel gtk2-devel bridge-utils PyXML \
 qemu-common qemu-img mercurial glibc-devel.i686Boris
