Apparently OVMF was trying to set up data structures inside the BIOS memory,
which no longer worked with the combination of BIOS-as-flash in QEMU and ROM
execution support in KVM. OVMF r14494 fixed this:

OvmfPkg/Sec: Build identity mapped pages in RAM for X64
This is based on MdeModulePkg/Core/DxeIplPeim/X64/VirtualMemory.c.
Previously we would run using page tables built into the
firmware device.
If a flash memory is available, it is unsafe for the page
tables to be stored in memory since the processor may try
to write to the page table data structures.
Additionally, when KVM ROM support is enabled for the
firmware device, then PEI fails to boot when the page
tables are in the firmware device.
