Re: [libvirt-users] inquiry about differences between the tap and the vnet in the virt-manager

inquiry about differences between the tap and the vnet in the virt-manager

when I establish the network by the first method: create a bridge with the help of Linux commad: brctl, tap0 device is created in the host and assigned to the guest OS. tap0 device gets a name “eth0” in the guest OS. I use “ping ” command to test network state . I get the following result : concept explanation : local host: the OS where the guest OS is running remote host: another server which is connected to the local host using ethernet network . and this is my results: ping local host from guest OS is OK, I get reply from local host; ping remote host from local host is OK, I get reply from remote host; ping remote host from guest OS is not OK, I don’t get any reply from remote host; and this is my question.
