I'm on Ubuntu 14.04 running kernel 3.19. I'm trying to use virt-manager to start a virtual machine. I have installed ovmf for EFI firmware and booted the machine with a Gentoo ISO in the CD slot.I see the OVMF firmware logo, then some log messages like this:Boot failed. EFI DVD/CDROMBoot failed. EFI Floppy.Boot failed. EFI Floppy 1.It then initializes the network card, presumably for network boot, and then drops to an EFI shell:How do I get EFI booting working in KVM/libvirt?
