Historically, VMs with vhost-user devices could hot-add memory a maximum of 8 times. Now that the VHOST_USER_PROTOCOL_F_CONFIGURE_MEM_SLOTS protocol feature has been added, VMs with vhost-user backends which support this new feature can support a configurable number of ram slots up to the maximum supported by the target platform. This change adds VHOST_USER_PROTOCOL_F_CONFIGURE_MEM_SLOTS support for backends built with libvhost-user, and increases the number of supported ram slots from 8 to 32. Memory hot-add, hot-remove and postcopy migration were tested with the vhost-user-bridge sample.
