According to this article: http://blog.xen.org/index.php/2011/06/02/xen-celebrates-full-dom0-and-domu-support-in-linux-3-0/
Xen is now fully supported in the Linux kernel without patches.
What is missing for xen support in e.g. 18.104.22.168 that you would download from kernel.org that is now available in 3.0?
It's a little confusing. I'm new to Xen and I am putting together a xen server that has GPU passthrough for 2 ATI Radeon cards and I'm just wondering whether I should straight go with Linux Kernel 3.0 if it's all there? I thought it was previously.
I'm looking at starting off with Ubuntu Natty. Any recommendations or links that might help me along the way?
