ESXi is completly isolated except the "backdoor" to communicate between guest and hypervisor (VMware HA, memory-ballooning) nearly all big software vendors are certifying for VMware (Microsoft, Oracle....) and even "hardware-appliances" are available for VMware: https://www.barracudanetworks.com/ns/products/vm_overview.php in fact ESXi is a own kernel VMkernel esx.thelounge.net 4.1.0 #1 SMP Release build-800380 Aug 2 2012 11:45:34 x86_64 unknown
