hi all, (this events ocurred before my previous mail about the uuid incident) so, I installed a vm host: rhel6 guest: centos6 network: bridge (br0, eth1 as slave) but then, I changed the name of the bridge from br0 to br1 (because br1<->eth1 seems pretty than br0<->eth1) so: - mv /etc/sysconfig/network-scripts/ifcfg-br0 /etc/sysconfig/network-scripts/ifcfg-br1 - edited /etc/sysconfig/network-scripts/ifcfg-br1 change DEVICE=br0 by DEVICE=br1 - edited /etc/sysconfig/network-scripts/ifcfg-eth1 and cha...

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 recently, using libvirt and KVM, I was creating VMs which had one interface attached the default virtual network and one interface attached to the bridge: virt-install ....

Maybe my google-fu is failing me, but I have spent the past couple hours looking at how to add a vnet? Device to my KVM host running CentOS 6, and for the life of me I can't get this going. >From all my research if I want to add a device I should just do 'brctl addif br1 vnet14' if I want to add a vnet14 to bridge br1.

I am experimenting with routing tables to obtain a little understanding of how things work. I have a kvm hypervisor host (KVM1) with two physical Ethernet nics configured as bridges (br0 and br1). KVM1 br0 is configured with a public ipv4 address [x.y.z.42/24] and br1 is configured with a private ipv4 address [192.168.216.42/24]. A second kvm hypervisor, KVM2, is similarly configured albeit with different IPv4 addresses of course. Packet forwarding is enabled on both hypervisor hosts and...

...nd in consequence it has been constantly shoved to the background as other issues arise. Here is the situation: I have two dual-homed kvm hosts both running CentOS-6.7 and identically configured. These are connected to the same LAN segment via br0/eth0 and to each other via a cross-over cable on br1/eth1. The IPv4 assigned to br0 on both is a publicly routeable address. The IPv4 assigned to br1 on both is a private address in the 192.168.0.0/16 address space. The guests on each host have their virtual eth0 bridged with their host's br0 and eth1 bridged with their host's br1. The ad...

The basic installation works fine until I start libvirtd; at this point, the host machine loses access to the external network: step 1: ping from host to network works; external machine on network can ping both eth0 and br1 on the host step 2: /sbin/service libvirtd start step 3: ping from host to network fails; external machine on the network can't ping either eth0 or br1 on the host Stopping libvirtd (/sbin/service libvirtd stop) makes no difference - the network remains unreachable.
