Bug 236380 – app-emulation/xen-tools-3.3.0 does not install pv-grub

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Rambaldi 2008-09-01 18:49:23 UTC]

Xen 3.3.0 introduced pv-grub, a more secure replacement for pygrub. 
The current ebuild does not install pv-grub.

Reproducible: Always

Steps to Reproduce:
1. emerge xen-tools 
2. create a domU based on /etc/xen/xmexample.pv-grub
3. boot the new domU


Actual Results:  
xen # xm create /etc/xen/xmexample.pv-grub
Using config file "/etc/xen/xmexample.pv-grub".
Error: Kernel image does not exist: /usr/lib/xen/boot/pv-grub.gz

Expected Results:  
Using config file "/etc/xen/xmexample.pv-grub".

From a post at http://forums.gentoo.org/viewtopic-t-709908-postdays-0-postorder-asc-highlight-pvgrub-start-25.html

I had a similar problem with the stubdom tools not being built, I emailed Robert Buchholz who maintains the ebuild and he explained that the build script downloads files in the build phase and that causes problems, so stubdom and pv-grub support is disabled in the ebuild.

I say this is a bug, not an enhancement! I'm also not buying that this situation has yet to be encountered in portage and no general solution worked out. In any case, it seems that the ebuild should be doing the downloading and the Makefile edited to present it with the downloaded stuff.

work in progress ebuild for pvgrub support

this ebuild uses the 'gentoo' way to download the needed components.
It fails however with a gcc error. I tried to fix this but have thus far failed in doing so.

app-emulation/xen-tools-3.4.0-r2

Attached my attempt to build xen-tools with pvgrub support. This ebuild uses downloaded files in $DESTDIR instead of wget, but it's still a hack.

patched ebuild for xen-tools-3.3.1

note: requires xen-tools-3.3.1-udevinfo.patch (see bug #236819)

[Comment 7 Nathan March 2010-06-22 19:15:17 UTC]

This is still an issue in xen-tools-4.0.0. pygrub should not be getting included due to security issues and this patch seems to work fine.

Can this please get addressed?

I got tired of patching the xen-tools ebuild, so I wrote ebuilds for pv-grub only.
They can be found in our overlay: http://subversion.fem.tu-ilmenau.de/repository/fem-overlay/trunk/ in app-emulation/xen-pvgrub.

We are using pvgrub on productive servers for some time now and didn't have any problems worth noting. Tested with Xen 3.3, 3.4 and 4.0.

Added a pvgrub howto using Peter Grobe's overlay:

Thanks Peter for the fine overlay.  Works great!

Cheers,

Xen 4.1 in tree. Please test with it and reopen if it doesnt work

[Comment 11 Rambaldi 2011-03-27 16:17:38 UTC]

After installing xen-tools-4.1.0 the support for pv-grub is still missing.

[Comment 12 Ian Delaney (RETIRED) 2011-10-04 14:21:51 UTC]

pv-grub works in 4.1.1 and has been tested.
Fixed in the tree.
