Environment: rhel7.5
I. Configuration firmware source
wget http://www.kraxel.org/repos/firmware.repo -O /etc/yum.repos.d/firmware.repo
II. Installation ovmf
edk2.git the install-ovmf-yum x64-
yum the install OVMF #uefi pattern of virt-manger component
III. libvirtd configured to enable UEFI
Configure libvirtd to advertise UEFI support
Libvirt needs to know about UEFI->NVRAM config file mapping, so it can advertise it to tools like virt-manager/virt-install.
As root, edit /etc/libvirt/qemu.conf, and add this section at the top of the file:
nvram = [
"/usr/share/edk2.git/ovmf-x64/OVMF_CODE-pure-efi.fd:/usr/share/edk2.git/ovmf-x64/OVMF_VARS-pure-efi.fd",]
IV. Restart libvirtd
systemctl restart libvirtd
V. Creating a Virtual Machine
virt-manager
So you can choose the firmware is uefi
note that if the video mode is vmvga or QXL will lead to a black screen at startup, and replaced it vga mode
