Jakub Staron a3411eaac1 crosvm: virtio-pmem device ... Adds support for virtio-pmem device as an alternative for virtio-blk. Exposing disk image to guest as virtio-blk device results in both guest and host independently caching the disk I/O. Using virtio-pmem device allows to mount disk image as direct access (DAX) in the guest and thus bypass the guest cache. This will reduce memory foodprint of the VMs. BUG=None TEST=cargo test TEST=Boot patched termina kernel in crosvm; mount virtio-pmem device as DAX and run xfstests.
