Good point. Sanity check question: Why not add the select stuff, i.e. this: select NET select NETDEVICES select PCI select BLOCK select BLK_DEV select NETWORK_FILESYSTEMS select INET select EXPERIMENTAL select TTY select SERIAL_8250 select SERIAL_8250_CONSOLE select IP_PNP select IP_PNP_DHCP select BINFMT_ELF select PCI_MSI select HAVE_ARCH_KGDB select DEBUG_KERNEL select KGDB select KGDB_SERIAL_CONSOLE select VIRTUALIZATION select VIRTIO select VIRTIO_RING select VIRTIO_PCI select VIRTIO_BLK select VIRTIO_CONSOLE select VIRTIO_NET select 9P_FS select NET_9P select NET_9P_VIRTIO to the option below which we already have. It is in the same sense a KVM guest support deal. Hmm. KVM people, any objections? config KVM_GUEST bool "KVM Guest support (including kvmclock)" depends on PARAVIRT select PARAVIRT_CLOCK default y ---help--- This option enables various optimizations for running under the KVM hypervisor. It includes a paravirtualized clock, so that instead of relying on a PIT (or probably other) emulation by the underlying device model, the host provides the guest with timing infrastructure such as time of day, and system time -- Regards/Gruss, Boris.
