It was reported [1] that on VM with relatively large amount (>12) of vCPUs boot process get stuck just after BdsDxe: loading Boot000C "ubuntu" from HD(15,GPT,...)/\EFI\ubuntu\shimx64.efi BdsDxe: starting Boot000C "ubuntu" from HD(15,GPT,... is printed to the VM console. Matthew Parkinson (topic starter) discovered that disabling SMM_REQUIRE helps to fix issue. Currently we don't know where the bug is, it can be Linux Kernel KVM, Qemu or EDK2. I'm on the way to make a good report for upstream developers. I was able to reproduce an analogical issue on my laptop with VM that has 15 vCPUs and can confirm that SMM_REQUIRE=FALSE fixes issue for me too. Reproducer rate on my environment is like 1/10. I believe that it makes sense to disable SMM as it should not make any troubles for our users but instead make VMs work for some users.
