Re: Unable to boot OVMF on qemu-x86_64

["Richardson, Brian" <brian.richardson@intel.com>]

The Ubuntu wiki info isn't quite up to date. We're maintaining updated build instructions on the TianoCore Wiki:
https://github.com/tianocore/tianocore.github.io/wiki/Using-EDK-II-with-Native-GCC#Ubuntu_1604_LTS__Ubuntu_1610 
https://github.com/tianocore/tianocore.github.io/wiki/How-to-build-OVMF

The README in OvmfPkg is going to be more up to date for OVMF specific info, but the wiki will have more general build info for different OS/compiler configurations.

Please let us know if you see issues with the wiki info so we can make updates. 

Thanks ... br

Did you build with "-DDEBUG_ON_SERIAL_PORT=TRUE" to enable the debug to go to the serial port?

Personally, I'd recommend *not* using DEBUG_ON_SERIAL_PORT, and instead of looking at tty0, add this to the qemu command line:

-debugcon file:debug.log -global isa-debugcon.iobase=0x402

Then debug.log will contain the debug messages.

(BTW, thanks Laszlo for implementing this! :)

Yeah. This is more up to date than the Ubuntu wiki. It also has the debugcon info...
