[Qemu-devel] [PATCH v2 3/4] vmdk: support vmfs files

[Fam Zheng <famz@redhat.com>]

From: Paolo Bonzini <pbonzini@redhat.com>

VMware ESX hosts also use different create and extent types for flat
files, respectively "vmfs" and "VMFS".  This is not documented, but it
can be found at http://kb.vmware.com/kb/10002511 (Recreating a missing
virtual machine disk (VMDK) descriptor file).
