I got the 2.6.39-rc3 kernel full source from http://www.kernel.org.
And CONFIG_PARAVIRT is turned on.
 
Here is the steps I configure the kernel:
1. Processor type and features
High Memory Support--->
64GB
(Then I can see PAE and some xen related options)
 
2. Processor type and features
--- Paravirtualized guest support--->
[*]Xen guest support
 
3. Device Drivers
Xen Driver Support--->
(All turned on by default)
 
4. Device Drivers
Metwork device support--->
<*> Xen network device frontend driver
<*> Xen backend network device
 
5. Bus options
<*>Xen PCI Frontend

Where did you get the 2.6.39 kernel from?
Did you turn on CONFIG_PARAVIRT=y
