Not at all. 

In fact, I'd strongly disagree with Daniel's characterisation that Xen 
has "stopped all kernel development" Redhat need to "finish off" the 
paravirt_ops port.  I've been working on it full time for the last 
couple of years, and have done the vast majority of the work needed to 
get paravirt_ops working.

Redhat have contributed valuable work in areas like the paravirtual 
framebuffer device, and are working on 64-bit and dom0 support.  But all 
of that is based on the work I've been doing on paravirt-ops 
infrastructure itself and the Xen implementation which uses it.

I'm still actively working on pvops/Xen, and currently focusing on 
bringing it up to feature parity with the old 2.6.18-xen patches.  In 
the last few weeks I've implemented balloon support, save/restore and 
starting work on pv-hvm driver support.

Meanwhile, open source Xen is also being actively developed by the 
original Xen developers and anyone who wishes to contribute.
