Re: [Qemu-discuss] Sparc Solaris Virtualization

[Jim Jarvie]

I think the issue is that the qemu-system-sparc64 emulates a PC style
bus (IDE devices etc.) rather than a SUN style bus, so the system starts
up and then discovers the IO devices it's expecting don't exist.

The standard 32 bit SPARC seems to properly emulate the SUN ESP bus.

Trying to select this on the sparc64 just gives an error that it is not
supported on this emulation.

Any other thoughts ?
