Mastering KVM Virtualization – Book
As mentioned in earlier chapters, in a KVM environment, the guest memory lies in the process address space of the qemu-kvm process in the KVM host. These guest memory pages can be swapped out by the Linux kernel at any time based on the requirement the host has. locked helps us here! If you have set the memory backing option of guest to locked, the host will not swap out memory pages that belong to the virtual system or guest. The virtual memory pages in the host system memory are locked when this option is enabled:
Note that, when setting locked, a hard_limit must be set in the
element to the maximum memory configured for the guest, plus any memory consumed by the process itself.
