Whoa I didn’t see that coming along so quick…

I was anxiously awaiting some VM/386 diskettes I ordered from Amazon to show up.

The main changelog hasn’t been updated since 0.12.5 so I really don’t know what to expect in this release.

One thing that is new, is QMP, the The QEMU Monitor Protocol.

Another interesting thing at a glance, is that 0.14 seems to have far more modes for the i386-softmmu..

pc         Standard PC (alias of pc-0.14)

The NE2000 still has a conflict on 0x300 IRQ 9, so removing it from hw/pc.c will allow the ISA NE2000 to function…

I also see the addition of the Intel HD Audio Controller, or hda, not to be confused with the first hard disk.

So for those of you who wish to give it a shot, here is the x86/x86_64 only version (what 99% of you want), and for the 1% crowd, the ‘other’ version which has all the OTHER cpu’s (mips,m68k,sh4,ppc).

And for some shameless google juice, here is the options for the new version of qemu-i386softmmu:

And because some people wanted it, here is *every* version of qemu I’ve found… in source!
