Comment 1 for bug 2004618

For reference, I'm attaching the logs I was looking at yesterday that pointed me to the virtinst issue. I collected it by turning on the following debug settings in libvirtd.conf:

log_filters="1:qemu_firmware"
log_outputs="3:syslog:libvirtd 1:stderr"

And ran libvirtd in the foreground to collect it.

You'll see that the probing pattern between old ovmf and new ovmf changed. After applying a patch to virtinst that also matches the 4M variants, the probing pattern when using the new ovmf now matches the old one.
