Yes, you only applied the patches that allow the FreeBSD loader to load 
Xen, but you also need all the patches for the FreeBSD kernel that 
enable PVH mode and Dom0 support.

The list is quite long TBH, and I haven't looked at whether all of them 
are needed or not, but a good start should be:

Re: Need help : 10.2 + Xen dom0 support

2015-10-08 Thread Shree Kantha 
Thanks a lot Roger for this information.

I am able to progress with this. I took below commits of you to stable 10.2:

   - rS280954: multiboot: fix error codes
   
   - Diffusion Commit
   - rS280953: multiboot: zero mod list array
   
   - rS277215: loader: implement multiboot support for Xen Dom0
   

With this, i build kernel, and followed steps mentioned in :
http://wiki.xen.org/wiki/FreeBSD_Dom0.

when my system reboots, I see below error:


"ERROR: Not a Xen-ELF image: No ELF notes or '__xen_ost' section found

***

Panic on CPU 0:

Could not set up DOM0 guest OS
***
Can you please tell me if I am missng anything here. Well, I took the above
mentioned fix to correct the multiboot support.If there are any other
patches to be used, plz let me know.

thanks a ton,
Shree

Any reason you cannot use HEAD instead?

Most of my commits need to be backported in order to have Dom0 support,
but IMHO, I'm not sure how many conflicts you will get when trying to
apply them to stable/10. You can get a list using `svn log --search royger`.

I'm not sure what you mean with this, which build fails?
