OVMF.fd <http://minnowboard.57273.x6.nabble.com/file/n1611/OVMF.fd>  

Thee is one more simple example:
we run qemu by using of the following line:
*qemu-system-x86_64 -bios ./OVMF.fd*
(the file OVMF.fd is in the attachment to the email)

Then we  run the command:
*dmpstore Boot0** and see 4 variables BootXXXX created

Then we run the command *setvar BootOrder =*

Then we run the command *reset*

After starting of Uefi shell we run the command *dmpstore Boot0** and see not 4 but 8 varables BootXXXX created.

We can repeat the operation sequence again but then by next start of uefi we will get not 8 but 12 variables BootXXXX created.

Could you please explain this situation?
