[Bug 1899370] Re: Can not install grub bootloader to /dev/sda

[ajgreeny]

zsync from the "current" to "pending" daily iso and choice of UEFI in
the virt-manager configuration for creating the KVM virtual machine has
now booted successfully.

I do not know if it was the move to the pending iso or to using UEFI
firmware that has made the difference, but it appears that the iso file
now defaults to UEFI when booted directly in KVM, probably also in
VirtualBox but I've not used VirtualBox so not sure about that.
