HyperVoria has listed the features that will be introduced with Hyper-V V2.0, some of which were public knowledge (live migration, cluster file system), some of which a few of us heard about but couldn’t comment on publicly (boot from VHD – the VM has dedicated hardware and the bootloader loads an OS from VHD instead of hard disk) and some of which were new to me (dynamically pooled RAM for VM’s, i.e. RAM over subscription as in ESX).
The latter may not make it into RTM of Windows Server 2008 R2. Hopefully it will.
