The challenge is to make the host machine with the VMM, ping the VM router and vice versa. The only difference to a previously working network build exactly like this, is the hypervisor/VMM was not KVM/Qemu/Virt manager. My network has: 1 pyhsical router bridged. 2 physical wired NICs for WAN and LAN. 1 host machine Debian based OS, running hypervisor/VMM KVM/Qemu/Virt manager. 1 VM router OPNsense (FreeBSD based). Please see the attachment for the network topology (note the VM router's install default IP address is , I will change this to when I have GUI access to the VM router's settings). The VM router is pinging the Internet and LAN devices. Here's 5 different /etc/network/interfaces configurations I've tried on the host machine, in attempt to connect the host&...

In SDNs I use mininet and create different topologies such as a tree, fat tree, linear, and others, connecting them with the Ryu controller to monitor flows. The switch I used is OVSK and the links are TC link with bw=0.01MBps, delay=1s, loss=50-90%, queue size=5-100packets, and use_htp=True. Also, change the used queue and Qos by "ovs-vsctl -- set Port s1-eth1 qos=@newqos .....". But when returning to the monitored flow I found that collision and Tx/Rx drop/error were always zero and did not change. The traffic generates using continuous ping, Iperf3, and python server and clients script. I need a dataset like the attached image that contains non-zero values for collisions and Tx/Rx drop/error monitored by the Ryu controller. I pay for the dataset and method. I will provide the ...
