Re: [libvirt] [Qemu-devel] [PATCH] vl.c: Support multiple CPU ranges on -numa option

Which you didn't ;) What about -numa node,cpus=A,cpus=B,cpus=C,cpus=D Yes, QemuOpts lets you do that. Getting all the values isn't as easy as it could be (unless you use Laszlo's opt-visitor), but that could be improved.
