Yes, I know Christopher Wojno has shared a method to install XS Tools in a Gentoo guest.

I just make a script that automates the process.

But, with a significant improvement (in my not-so-humble opinion): My script does not install the RHEL/CentOS initscript, but installs its own custom OpenRC-compatible initscript.

The script itself, at 402 lines, is perhaps too long to post here. So I share it for all on BitBucket:

https://bitbucket.org/pepoluan/install-xe-guest-utilities-for-gentoo

Comments are welcome!

Edit: IMPORTANT NOTICE: The script has been fixed, and just pushed to BitBucket. Sorry for the inconvenience.

Are you using a custom kernel? If so, can you post your .config as well? I have a gentoo VM running on a citrix xen host, but the kernel was taken from a different distro, and is pretty ancient.

Just the most recent hardened sources, but with deeply-customized .config (had to dig around to enable *all* Xen guest pv_ops options. (And disable all unnecessary options).

I'll post my .config here on Monday when I get back to the office.

BTW, the script -- and the .config -- has been tested, and it works splendidly on my VMs, which has gone into production. I'll post the .config of my latest VM, which is a Squid3 server. And I definitely am *very* satisfied of its performance after addition of the guest utilities :)

I feel ashamed...

Please read the 'VERY IMPORTANT NOTICE' on the 1st post before anyone thinks of trying my script.

*Nearly died of embarrassment*

Edit: Script at BitBucket has been fixed.

Hmm... lots of people seem to have problem with paravirtualization of x86 kernel.

I'm currently writing an article for Gentoo Wiki. I'll post the link here when it's finished.

As promised, here's my .config:

Code:
Linux/x86_64 2.6.39-hardened-r4 Kernel Configuration

ebuild for XenServer Tools is finished. I think. Find it here:

https://bitbucket.org/pepoluan/xe-guest-utilities-ebuild

IMPORTANT NOTE: It is NOT YET tested!! Just eyeball it, and tell me if I made some stupid or not-so-stupid mistakes.

Looks great!

2 questions, can you include your kernels .config and do you have a base template you would share?
