As announced last month, newest Linux kernel version, 2.6.21, includes for the first time an adapted version of VMware Virtual Machine Interface (VMI), able to interoperate with paravirt_ops virtualization interface.

At this point new Linux distribution going to use this kernel version will be able to run paravirtualized in upcoming VMware Workstation 6.0, and at a later time in Server and ESX Server new releases.

But kernel 2.6.21 also introduces remarkable new KVM features:

  • Initial paravirtualization support
  • Live migration (the guest continues running even while being migrated) support
  • Host Suspend/resume support
  • CPU hotplug support
