Public bug reported:

Using nova to boot UEFI instances in certain circumstances the nvram is
cleared

e.g. on a deployed node my nvram is set too boot from the grub installed
on the EFI partition

[root@t1 boot]# efibootmgr 
Timeout: 0 seconds
BootOrder: 0004,0002,0000,0001,0003
Boot0000* EFI Floppy
Boot0001* EFI Floppy 1
Boot0002* EFI Hard Drive
Boot0003* EFI Network
Boot0004* centos


This is working I can run 
> nova reboot dbdc6b36-1f17-4722-89e5-117986b10059

but if I run a nova reboot --hard or a combination of nova stop/start
then the libvirt domain is redefined, as part of this process the nvram
is reset, the boot process stalls at the boot menu and I have to select
boot from file

[root@t1 boot]# efibootmgr 
Timeout: 0 seconds
BootOrder: 0002,0000,0001,0003
Boot0000* EFI Floppy
Boot0001* EFI Floppy 1
Boot0002* EFI Hard Drive
Boot0003* EFI Network
