Re: [Qemu-discuss] Any trick to booting off a eufi USB flash drive?

[Pascal]

hi, I'm on ArchLinux and I don't use libvirt, so my answers won't
completely cover your questions.

I'm using OVMF-pure-efi.fd from edk2.git-ovmf-x64 from
https://www.kraxel.org/repos/jenkins/edk2/ and I'm calling qemu like this :

/usr/bin/qemu-system-x86_64 -enable-kvm -m 2048 -bios OVMF-pure-efi.fd -hda
/dev/sdx

(assuming your USB flash drive is /dev/sdx and is readable)

are your really sure your USB flash drive is UEFI ready ?

I hope it will help.
