Hello,
I am trying to use the vsocket interface for the RPCIn channel (Host-->Guest communication) in order to receive TCLO messages using vsockets.
However, this channel is always falling back to backdoor as seen in the guest's vmsvc.log. Thus, the events for power operations like suspend, resume, shutdown etc arrive in guest VM through backdoor and not vsock.
The RPCI channel for guest-->host communication seems to work successfully using vsockets.
Also, in host's vmware.log the
"GuestRpc: Using vsocket for TCLO messaging is disabled" message is displayed.
I use the default settings of VMware Tools in host and guest.
Could anyone help me how to explicitly use TCLO channel with vsockets?
Some usefuls logs can be seen below:
