Re: [Xen-users] [Xen-devel] How come Linux kernel 3.10 does not have Xen configuration options any more?

["Singapore Citizen Mr. Teo En Ming (Zhang Enming)" <singapore.mr.teo.en.ming@xxxxxxxxx>]

Even though I have enabled CONFIG_HYPERVISOR_GUEST=y, I still don't see 
the xen configuration options.
