Re: [Qemu-discuss] more memory, more resolution

[Hua Wang]

Sorry I have not much experience on QEMU so might not be able to help on your 
question, but I would like to ask a related question. 
Does anyone know how to emulate X86 OS/application on a ARM host? Is there any 
successful case?

Thank!

Regard,
Hua
