similar to: Problems setting up bridge

Hi, I have an existing fedora14 system with two interfaces and several virtual interfaces (as in eth0:0, etc). They are currently configured to not be controlled by NetworkManager, but just standard network services. I've recently started working with libvirtd, so I also have a virbr0 interface as well that has its own network and is masquerading the networking for the single KVM instance I

Hello I have a problem with attaching VMs to a VLAN interface. Here is my setup: I have several physical hosts connected by a physical switch.  Each host has two NICs leading to the switch, which have been combined into a team, team0. Each host a has a bridge br1, which has team0 as a slave. So communication between hosts is based on the IP address of bridge br1 on each host. Up until

Even more puzzling, I reverted back to the old configuration to confirm what I had seen and found that it works in one direction but not the other: i.e. from 192.168.0.110 to 192.168.0.120, but not the other way around. Must be something with my configuration....which I can follow up on. So, thanks again for your help. Richard On 12/3/19 11:36 AM, Richard Achmatowicz wrote: > Laine >

Hi Laine What you have suggested sounds eminently reasonable. Thanks for your advice. I'm going to give it a shot and report back.

Laine I made the change and I can now ping across both bridges: br1 (192.168.0.0/24) and br1600 (192.168.1.0/24): br1: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500         inet 192.168.0.110  netmask 255.255.255.0  broadcast 192.168.0.255         inet6 fe80::1e98:ecff:fe1b:276d  prefixlen 64  scopeid 0x20<link>         ether 1c:98:ec:1b:27:6d  txqueuelen 1000  (Ethernet)

G'day, I have a host running two kvm guests. One of them gets very poor network performance, testing with iperf I get ~10MBit/sec to guest A, >400MBit/sec to guest B (running iperf between the host/guest). Both guests are using the same bridge: Guest A: <interface type='bridge'> <mac address='54:52:00:75:24:91'/> <source

Hello, I have problems with installation of my second DomU. I cannot ping it from the outside world and I cannot access outside world from this domain. I see it from Dom0 and my first DomU, same as my second DomU can ping Dom0 and my first DomU. I use xen 3.0.3 on ubuntu 6 LTS. DomU is running on debian. I also network-bridge script in the xend config.

Well where do I start...I have a domU (ubuntu) booting and appears well but I don''t have an eth0 listed at all, dom) looks good.

Our small network is 10.10.11.0/24, gateway 10.10.11.252. dhcp is set up. I'm using virt-manager to install VM's with kvm-qemu on an F14 host - 10.10.11.100. qemu-kvm-0.13.0-0.6.rc1.fc14.x86_64 libvirt-0.8.3-2.fc14.x86_64 I'd like all the VM's to be on the same network as the physical machines with an address range of 10.10.11.110-10.10.11.130. I have virt-net set up. ifconfig

Hi I''ve got a (gentoo) box set up for xen, 2.6.21-xen kernel as per portage about 2 weeks ago. Already got all my guests set up and almost good to go, except for very erratic networking issues. Networking on the domU''s does not always work. I have set up two physical adapters, and bridged both (by use of the modified network-bridge script from the archives) adapters for use

Hi all, I have a problem to get my Linux machine to masquerade for other computers on the network. My main machine is connect to the ADSL modem on eth0. The machine also has another network card, eth1 which connects directly to the other computer. Both machines can ping each other fine, but I can''t access the net from the other (Windows) system.

I am running Fedora 16 64bit and installed libvirt. I have the VM running with arm emulation with this one issue I can't figure out. I used Virtual Machine Manager to manage the VM and can access its console there. The Ethernet appears to be eth1 and the guest can set an IP on it etc. However, I cannot see any traffic from the Host when dumping any of the interfaces. I've tried
