Can you specify more RAM for the guest? The default is 128 MB I think.

The "minimal" (no network) command line I recommended most recently was
<http://thread.gmane.org/gmane.comp.emulators.qemu/197386/focus=197403>.
Maybe you could try that first and work from there. You can also grab a
prebuilt OVMF binary from the link in that post.

The serial console is not only output under OVMF but input too, so
redirecting it to a file is not optimal. If I use serial for the debug
messages rather than the qemu debug port, I connect to the serial
console from within "screen", which both works as a terminal and can
capture the output in a file. (The edk2 / OVMF text UI and the debug
messages will be intermixed.)

Also, gEfiMdePkgTokenSpaceGuid.PcdDebugPrintErrorLevel should already be
in OvmfPkg/OvmfPkgX64.dsc, you only need to change the value for
DEBUG_VERBOSE. However even without touching it at all it should produce
lots of DEBUG_INFO and other messages.
