Re: [Xen-devel] pvops kernel question

[Onkar Mahajan <kern.devel@xxxxxxxxx>]

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 ?

Regards, 
Onkar

Yes, Fedora's kernel is pvops, since pvops is in upstream kernel.org kernels.

Just grab latest kernel from kernel.org and build with Xen pvops options enabled.
