...ransport provides both g2h and h2g behaviors in a single transport. We are able to set (or not) the g2h behavior, detecting if we are in a VMware guest (or not), but the h2g feature is always set. This prevents to load other h2g transports while we are in a VMware guest. This patch adds a new 'transport_hg' to handle this case, reducing the priority of transports that provide both g2h and h2g behaviors. A transport that has g2h and h2g features, can be bypassed by a transport that has only the h2g feature. Signed-off-by: Stefano Garzarella <sgarzare at redhat.com> --- net/vmw_vsock/af_vso...

...we are in a > VMware guest. In the vhost_vsock.ko case we only register the h2g transport when userspace has loaded the module (by opening /dev/vhost-vsock). VMCI has something kind of similar: /dev/vmci and the vmci_host_active_users counter. Maybe we can use this instead of introducing the transport_hg concept? -------------- next part -------------- A non-text attachment was scrubbed...
