Re: [libvirt-users] libvirt remote connection



It seems, that I have turned off all encryption for tcp in libvirt.conf, but still rpc packets are not showed, only tcp. I suppose, that I don't need to add additional plugins to wirehark for libvirt and rpc, am I right?

Libvirt uses a custom RPC protocol running above a number of different
transports (TCP with SASL, TCP with TLS, SSH tunnel, etc, etc). Libvirt
ships a wireshark plugin that can be used to analyse the network stream
but you would have to turn off all authentication and use plain TCP
to be able to see it otherwise it'll be encrypted and wireshark won;t
see anything
