A problem with live migration of UEFI virtual machines
We found a problem with live migration of UEFI virtual machines due to size of OVMF.fd changes.
Specifically, the size of OVMF.fd in edk with low version such as edk-2.0-25 is *2MB* while the size of it in higher version such as edk-2.0-30 is *4MB*.
When we migrate a UEFI virtual machine from the host with low version of edk2 to the host with higher one, qemu component will report an error in function *qemu_ram_resize* while
checking size of ovmf_pcbios: *Length mismatch: pc.bios: 0x200000 in != 0x400000: Invalid argument.*
** We want to know how to solve this problem after updating the version of edk2.

Hi all,You can only migrate a machine that is identical - so instantiating a
empty machine with a different EDK image is bound to cause a problem
because the machines don't match.
