IPVS is not a kernel process. It is part of the core kernel. And it runs on multiple cores, just as the rest of the core kernel does - assuming an SMP kernel. As IPVS acts on packets, and packets come from network interfaces (usually), some control over which CPU ip_vs is executing on can be had by setting the affinity of a particular interface (PCI device) for to a core. -- Simon Horman VA Linux Systems Japan K.K., Sydney, Australia Satellite Office H: www.vergenet.net/~horms/ W: www.valinux.co.jp/en _______________________________________________ Please read the documentation before posting - it's available at: http://www.linuxvirtualserver.org/ LinuxVirtualServer.org mailing list - [email protected] Send requests to [EMAIL PROTECTED] or go to http://lists.graemef.net/mailman/listinfo/lvs-users
