No bias or spin ? #
"support as many as 64 processor sockets ... (VMware's ESX Server 4.0 hypervisor ... can't come anywhere close to this ..."
I suspect only the large IBM/HP/Sun boxes support this number of sockets, which isn't exactly mass market. I bet most people buy machines with 2-4 sockets.
"With the bare metal hypervisor, it is running right on the iron and it is in theory more secure..."
So there's been no security warnings about VMs under XEN being able to see other VMs on the same box ?
"...more reliable..."
And no-one's ever crashed one of these super-duper hypervisors, have they ? Oh I'm the only one, am I ?
"..and more efficient."
VMWare released a white paper a while ago comparing the speed of their ESX against a native/hardware virtualisation (i.e. using the processor extensions) Their conclusions: It depends. In some workloads the hardware virtualisation is faster, in others, the software is faster.
To be fair, it does seem cheap compared to VMWare.
