Hey there ... a question about UEFI booting of VMs. i.e. glance image-create --file cloud-2730. qcow --disk-format qcow2 --container-format bare --property “hw-firmware-type=uefi” --name clear-linux-image
in order to specify that you want to use UEFI (instead of BIOS) when booting VMs with this image i.e. /usr/share/OVMF/OVMF_CODE.fd /usr/share/OVMF/OVMF_VARS.fd and I believe you can boot into the UEFI Shell, i.e. to change UEFI variables in NVRAM (OVMF_VARS.fd) by booting VM with /usr/share/OVMF/UefiShell.iso in cd ... e.g. to changes Secure Boot keys or something like that. My QUESTION ... · how does NOVA manage a unique instance of OVMF_VARS.fd for each instance ? o i believe OVMF_VARS.fd is suppose to just be used as a template, and is supposed to be copied to make a unique instance for each VM that UEFI boots o how does NOVA manage this ? § e.g. is the unique instance of OVMF_VARS.fd created in /etc/nova/instances/<UUID>/ ? o ... and does this get migrated to another compute if VM is migrated ? Greg.
