Well put, I also think that too.

I think the failure of Xen was it's failure to get included in the Linux kernel
early on. Now it's too late, there is such a wide gap between their
2.6.18 kernel and the current 2.6.27 kernel and the work to catch up
their hypervisor/kernel to current is going to make the work of polishing
their existing code suffer, not to mention that the distributions out there
are readying new releases on more current kernels that won't have the
Xen api built in and will need to either drop or patch/maintain them
which is too much work/effort = $$$.

Not getting Xen into the kernel earlier is going to be Xen's downfall.
