Hi, I wan?t to add iptables rules between existing rules and the rules created by libvirt (forward type=nat). I did try the hook /etc/libvirt/hooks/network network_name start begin - and /etc/libvirt/hooks/network network_name started begin - It seems like the libvirt iptables rules are already inserted when this hook is executed. Simply use ?I instead of ?A does not work either because the rules should be inserted between the existing one and the libvirt r...

Hi, I’m an openstack developer trying to use Assignment from a pool of SRIOV VFs in a libvirt <network> definition from this link http://wiki.libvirt.org/page/Networking My question is is it possible for nova (the openstack compute) to know which VF out of the pool will be allocated to a VM before it invokes libvirt to launch it? Thanks In advance, Robert

Hello, I have a set of iptables rules that I need to insert *after* libvirt has set up all of its firewall rules. Is there a hook that I can tap into in order to run something like a custom script to make sure this happens? Any ideas? -GN

...; > -GN > You should be able to use a libvirt network hook script to do this: https://libvirt.org/hooks.html Basically you put an executable script in /etc/libvirt/hooks/network Once the network is started, the hook will be called with this commandline: /etc/libvirt/hooks/network network_name started begin - stdin will contain the entire network XML definition in case you want details, or want to extract some task-specific metadata from the network definition (syntax for that is here: https://libvirt.org/formatnetwork.html#elementsMetadata ) The same script will be called before t...

What is the best way to stop CentOS 6 from renaming the eth0 interface to em1? I've googled a bit and found many relevant posts, but have still not come up with an elegant solution. One of the resources I found was http://www.arachnoid.com/linux/network_names/index.html, and while the Python script contained therein does create a new udev rule that renames em1 back to eth0 it feels kludgy and requires me to manually create the ifcfg-eth0 script. I'm looking for a way to stop udev from renaming the interface in the first place, preferably somethin...

Hello, I wanted to get an extra IP on my local NIC, so I ran `sudo ip addr add 192.168.1.130/24 dev enp4s0`. This didn't work as intended, so I thought I'd restart the Ubuntu system to have things back to how they were. Alas, this didn't happen. While the host still has network as usual, none of the VMs are able to get a DHCP lease from the router, or any connectivity at all. I can

...nodes participate in the spike. Some nodes just have a spike on output, some only on input. ? I see a bunch of these lines in the logs on all the servers with the spikes, each about one or two other nodes: ``` Got late or replayed packet from <NODE_NAME> (<INTERNAL_IPv6_ADDRESS>%<NETWORK_NAME> port 655), seqno 235266, last received 235410 ``` ? What causes this and is there a way to prevent these spikes? I estimate an extra 4-5GB of extra bandwidth usage per node because of this. ?
