similar to: creating a network on existing bridge

I also have problems with a live migration. I’ve experienced that migrating over tcp instead of ssh is more stable. But with big disks ( > 30Gb) and –copy-storage-all, I keep getting problems… for now I don’t use it.

Hi everyone! I have the following setup: domain0 |-domU1 |-domU2 |-domU3 I am running this with libvirt on a XEN server. Right now the server is connected to our office network, but later it will be in a hosted environment. I need domU1 and domU3 to have a public IP, and all of the domUs and the dom0 should have an internal IP address to communicate with each other. So this is what I would like

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

Greetings, I'm trying to add a virtual nic to an existing and active vm and I'm getting this error: error: internal error: No more available PCI slots the cmd I'm trying to run is: virsh -c qemu:///system attach-interface --domain router --type bridge --source virbr0 --model virtio --config --live the lspci output within the vm is this: # lspci 00:00.0 Host bridge: Intel Corporation

Hi, I have an existing OVS bridge, that I can see in ovs-vsctl and use for other purposes. I've edited the machine's XML as instructed in http://docs.openvswitch.org/en/latest/howto/libvirt/ When I try to start the VM, i get error: Cannot get interface MTU on 'ovsbr': No such device Any ideas? (Note: I can't see the ovs switch in brctl show or any other regular kernel tool,

Hi, All! I found a bug!

Hi all, When I defined a network use the host bridge "virbr1" an error occurred : "libvir: error : Unable to create bridge virbr1: File exists" But how can I define this network use the host bridge "virbr1" ? <network> <name>def1</name> <bridge name='virbr1'/> <forward mode='nat'> <interface dev='eth0'/>

Hello all! I try to use network filters for openvswitch interfaces.  This is the xml configuration of my bridge interface <interface type='bridge'>    <mac address='00:11:22:33:44:55'/>    <source bridge='virbr1'/>    <virtualport type='openvswitch'>         <parameters interfaceid='0529d6b5-627c-4330-803f-0d7018e6d496'/>

Hi: Currently we encounter a problem where OpenStack may forget or misconfig the bridge hairpin setting, and will cause some unexpected behavior [1]. Although this bug is marked fixed, but if we manually restart the vm by virsh will also trigger the problem. And because the bridge interface is created and managed by libvirt, we are considering move the hairpin configuration to libvirt.

Hi all, Can you please explain to me what is the difference (or maybe the relation?) between a libvirt defined network and an openvswitch bridge? best, Po

Hello, I'm just wondering why I can't manage my network interfaces through libvirt when the following kernel parameters are turned on: net.bridge.bridge-nf-call-ip6tables net.bridge.bridge-nf-call-iptables net.bridge.bridge-nf-call-arptables Is it a bug or by design? If the latter, could someone explain me premises of such decision? I'm aware of security implications of mixing
