Introduce file locking for the virtio block device's disk image to prevent multiple processes or VMs from accessing the same disk image concurrently, which could lead to data corruption. A shared lock is used for read-only access, and an exclusive lock for read-write access. Signed-off-by: Changyuan Lyu <changyuanl@google.com>
