Okay, I've just tried an F11-Preview install and it worked for me, grub
installed just fine.

No, it won't help the problem you saw where anaconda didn't install the
bootloader because anaconda/booty doesn't suffer from this grub-install
issue ... it just runs:

Note, anaconda/booty doesn't suffer from the grub-install problem
because it does:

Running... ['/sbin/grub-install', '--just-copy']
Running... ['/sbin/grub', '--batch', '--no-floppy', '--device-map=/boot/grub/device.map']


    GNU GRUB  version 0.97  (640K lower / 3072K upper memory)

 [ Minimal BASH-like line editing is supported.  For the first word, TAB
   lists possible command completions.  Anywhere else TAB lists the possible
   completions of a device/filename.]

 Filesystem type is ext2fs, partition type 0x83

No device.map is used by default. And AFAIK, you need one with virtio
because the BIOS doesn't know anything about the drive.
