Re: [Qemu-discuss] Multi-node QEMU

[Javier Picorel]

Dear Wacha,

Thanks for your reply. The cycle-accurate models are built on top of QEMU. As 
an example, MARSS86 in as cycle-accurate x86 simulator that 
works on top of QEMU. Going back to my question, can we boot a multi-node setup 
within one QEMU process? Thanks!

Regards,
Javier
