I read here http://wiki.xensource.com/xenwiki/XenParavirtOps
this :
Using Xen/paravirt_ops
Building with domU support
1. Get a current kernel. The latest kernel.org kernel is generally a good
choice.
2. Configure as normal; you can start with your current .config file
3. If building 32 bit kernel make sure you have CONFIG_X86_PAE enabled
(which is set by selecting CONFIG_HIGHMEM64G)
- non-PAE mode doesn''t work in 2.6.25, and has been dropped
altogether
from 2.6.26 and newer kernel versions.
4. Enable these core options:
1. CONFIG_PARAVIRT_GUEST
2. CONFIG_XEN
5. And Xen pv device support
1. CONFIG_HVC_DRIVER and CONFIG_HVC_XEN
2. CONFIG_XEN_BLKDEV_FRONTEND
3. CONFIG_XEN_NETDEV_FRONTEND
6. And build as usual
My question is :
I have original kernel of FC12 that has all the configuration options as
shown above ? Does this kernel can act as a
pvops kernel ?
If I choose to build my own pvops kernel , how do I do it ?
Regards,
Onkar

Thank you very much, Pasi , for your help. Just a novice question - when I build xen-4.0.0 (from here http://bits.xensource.com/oss-xen/release/4.0.0/xen-4.0.0.tar.gz) , it downloads pvops kernel , is there any way I can use my own pvops kernel instead of this ?
