Xen Virtualization on Linux and Solaris

This is the best book i’ve ever read in my life about architecture of Xen Hypervisor, concepts of paravirtualization, dom0,domU, performance advantages of PV guests.
I would say that core theoretical background of Xen Hypervisor is written pretty clear. It brings comprehension of Xen to persons, which even wouldn’t be willing to work on this topic too much. The last is very important from my standpoint.
I also believe that Xen 4.0 + PVOps kernel based Jeremy’s git branch xen/stable would bring Xen far ahead KVM in about one year. “Kernel to support Dom0” problem is pretty much solved. Xen Hypervisor itself doesn’t require any additional comments.
Regarding Sun xVM 3.4.2 i would add that “virt-install” was always considered by Sun as core installation technology, “virsh & virt-manager ” as a tool for domain management. Sun was
focused on Libvirt interface to Xen on OpenSolaris ( former Nevada) from the very beginning ( SNV_75)
