Hi - In a KVM/qemu environment is it possible for the host to back only a portion of the guests memory with huge pages? In some situations it may not be desirable to back the entirety of a guest's memory with huge pages (as can be done via libvirt memoryBacking option). What would be very useful is to request huge pages in the guest, either at boot time or dynamically, and have the host back them with physical huge pages, but not back the rest of the normal page guest memory with huge pages from the host.
The equivalent in Xen is setting allowsuperpage=1 on the hypervisor boot line. Thanks Chris -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
