Hello, I am working on Network-Simulation (VNUML). Our simulator uses linux bridgi= ng to connect the UMLs. So there is one problem: The example is the following: There are two hosts simulating one big net. The two hosts have connection over the external nets Net3 and Net6 (see htt= p://www.uni-koblenz.de/~timbub/verteilteSim3.GIF), but in fact there is onl= y one physical connection between the

hi guys I wonder if any of you might be using SFN6122F-R7 SFP+ (SFC9000, same firmware everywhere, Centos 7.5 too. I'm trying poor man's setup to get the servers onto 10GbE network. Setup is such that three Dell R815 are connected to each other, each has one Solarflare(SFP ports) and each Solarflare is set as net-team(both ports on a card are net-team device) with runner in broadcast

Greetings - I shutdown one of my Centos 6.2 VMs for some offline maintenance and am now unable to get it to restart. I am also unable to create and start a new VM. The host system is Centos 6.2, fully up to date. I have been searching Google for two days and have not been successful in getting a VM to start. I have restarted libvirtd, but did not want to shutdown my other two running VMs and

hi everyone I'm having a bit of a puzzle on one centos system, I have four interfaces: nm-team1 10.5.6.100 em1 192.168.2.17 em2 192.168.2.18 p3p3 172.25.12.222 I do: ping 10.5.6.17 -I em1 PING 10.5.6.17 (10.5.6.17) from 192.168.2.17 em1: 56(84) bytes of data. 64 bytes from 10.5.6.17: icmp_seq=1 ttl=64 time=0.367 ms the same for -I em2, for -I em1 and naturally for -I nm-team1 - all good.

This is unfortunate. https://wiki.libvirt.org/page/TroubleshootMacvtapHostFail To the "normal" user - BRIDGE means guest is on the same network and has access to the host. Bummer. Jerry

hi, I have configured a routed network on my laptop with a ipv6 subnet and dnsmasq is handing out ipv6 addresses to my vms and it works really wel, but finding out which ips have been used is not as easy as with ipv4. [root at lenovo ~]# virsh domifaddr --domain wec --source lease Name MAC address Protocol Address

Hi all, How can I see what vnet is attached to a certain kvm guest?? For example: I have a kvmguest1. When I launch this guest with virsh command, virsh creates a new vnetX interface for this guest. How can I extract this virtual net interface (vnet0, vnet1, vnet2 or so on) using a script?? Thanks. -- CL Martinez carlopmart {at} gmail {d0t} com

I am running NOX controller with a python script that prints out the destination mac and the source mac for each packet arriving at the now controller and then floods it out. So here's what happening: With em1 connected, all the packets that arrive at em1 are coming to the controller and printing out the details. However, without em1 connected to the OVS, when I have the following setup:
