XenServer 7.0 performance improvements part 3: Parallelised plug and unplug VBD operations in xenopsd

The XenServer team has made a number of significant performance and scalability improvements in the XenServer 7.0 release.

As such, if the local root user's (LRU) password for a XenServer 7.0 is forgotten physical (or "lights out") access to the host and a reboot will be required.  The contrast comes with grub2, the methods to boot the XenServer 7.0 host into single...
