Ideally, as vcpu as just normal threads, the usual userspace tools can be used to set cpu affinities mask. However, It makes it very difficult to _start_ a vm with vcpus pinned, since we don't know the thread ids from qemu in advance, nor do we know when are the vcpus created. The patches introduce a -cpu-map option, that, if specified, starts the virtual cpus with the specified affinities. Comments? Welcome. Random rants? Not welcome, but... how can I stop you? So go ahead! ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
