the main new features of vhdx format are:

  • support virtual hard disk storage capacity of 64 tb.
  • protection against data corruption during power failures logging updates vhdx metadata structures.
  • improved alignment of virtual hard disk format work on large sector disks.

the vhdx format provides following features:

  • larger block sizes dynamic , differencing disks, allows these disks attune needs of workload.
  • a 4-kb logical sector virtual disk allows increased performance when used applications , workloads designed 4-kb sectors.
  • the ability store custom metadata file user might want record, such operating system version or patches applied.
  • efficiency in representing data (also known “trim”), results in smaller file size , allows underlying physical storage device reclaim unused space. (trim requires physical disks directly attached virtual machine or scsi disks, , trim-compatible hardware.)

all os in windows server 2012 hyper-v supported guested operating systems list can installed in vhdx disk, of course include windows server 2008 r2. vhdx disk format technology not supported in windows server 2008 r2.
