[Bug 1001325] [NEW] grub pxe not working in qemu

[Pali]

Public bug reported:

I installed grub into /var/lib/tftpboot/ (which is root of tftpd-hpa)
$ sudo grub-mknetdir --net-directory=/var/lib/tftpboot/

Then I created tap0 interface:
$ sudo tunctl -t tap0 -u pali

I trying to boot grub via pxe, but only rescue grub mode is started. I show error "error: no such disk."
$ qemu-system-x86_64 -curses -net tap,ifname=tap0,script=/bin/true,downscript=/bin/true -net nic
