Maciek Swiech f4c5cd8e42 balloon: return balloon_actual with wss 
balloon size is useful for balloon policies using working set size, so
we return the balloon-device cached balloon size. unless there is some
error in adjustement of the balloon, this should reflect that real
balloon size and saves having to query the guest an additional time.

crosvm - The ChromeOS Virtual Machine Monitor

crosvm is a virtual machine monitor (VMM) based on Linux’s KVM hypervisor, with a focus on simplicity, security, and speed. crosvm is intended to run Linux guests, originally as a security boundary for running native applications on the ChromeOS platform. Compared to QEMU, crosvm doesn’t emulate architectures or real hardware, instead concentrating on paravirtualized devices, such as the virtio standard.

crosvm is currently used to run Linux/Android guests on ChromeOS devices.
