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.
