We'd better change it. Suppose your vcpu is spinning, and you want to find out why? One nice thing would be to add an on_vcpu(void (*func)(void *data), void *data), so that people don't have to open-code it for things like this. I tried to do this once, but backed off due to the mess that qemu-kvm threading was at the time. I think it's much better off now. -- error compiling committee.c: too many arguments to function ------------------------------------------------------------------------- This SF.net email is sponsored by the 2008 JavaOne(SM) Conference Don't miss this year's exciting event.
