Hi everyone, When i start a libvirt domain (on KVM) with network filtering (using filterref clean-traffic for example), the filter works ! But ... i don't understand how/why it works :( Indeed when i look at ebtables -L iptables-save & arptables-save (and KVM command), I see no filtering rules (which is surprising because clean-traffic requires at least ebtables to be installed). Is it

Dear all, I configure my kvm vm like this: <interface type='bridge'> <mac address='52:54:00:dd:b2:c5'/> <source bridge='nw-vpc-1017'/> <target dev='if-57'/> <model type='virtio'/> <filterref filter='clean-traffic'> <parameter name='IP'

I have an issue setting a persistent kernel option on a libvirt net device since that device does not exist early enough during the boot of the KVM host. I am using the 127.0.0.0 local net for cluster communication between the KVM host and its guests as well as between KVM guests. In order to use addresses on the 127.0.0.0/8 network, which is reserved for local communication, two configuration

Hi, I'm trying to configure nwfilter for KVM, but so far I haven't managed to figure out a working configuration. Network setup: The dom0 (Debian 7.1, kernel 3.2.46-1, libvirt 0.9.12) is connected via eth0, part of the external subnet 192.168.17.0/24, and has an additional subnet 192.168.128.160/28 routed to its main address 192.168.17.125. The host's subnet is configured as bridge

Hi I am using Libvirt 1.1.2 with Openstack Havana (RC2, nova-network) and openvswitch 1.4.2+git20120612-9.1. Libvirt vif driver ( nova.virt.libvirt.vif.LibvirtGenericVIFDriver) generates config likes this: <interface type='bridge'> <mac address='fa:16:3e:44:30:a4'/> <source bridge='br0'/> <model type='virtio'/>

Hi there. I have configured kvm domain (rhel6.4) with ethernet bridged over macvtap, and found no filtration applied except mac. 'virsh' just silently ignoring attributes 'filterref' and 'ip address' in different formats. No error on validate stage. Config examples: ... <interface type='direct'> <mac address='52:54:00:31:ae:1a'/>

Hello, I would like to make filter that allows communication only between specified VMs. Those VMs should be specified by their MAC address. The filter should extend clean-traffic but I was not able to get it working with that reference. I have came up with modified clean-traffic which works fine [1]. Is there a way to achieve the same behavior with reference to clean-traffic? Thank you. Best

I'm trying to accomplish what I had hoped would be a fairly simple filtering of traffic to my VMs, but I'm hitting a snag. The VMs are allowing traffic when I wouldn't expect them to. Host and Guest are both running the same platform: Ubuntu 12.04.4 LTS 0.9.8-2ubuntu17.19 I have a basic bridge enabled on the host: brctl addbr brdg brctl addif brdg eth1 ip link set brdg up The host

To take advantage of the filters, is it as simple as adding these couple of lines in a guest's xml file like the example from https://libvirt.org/formatnwfilter.html#nwfconcepts ? <devices> <interface type='bridge'> <mac address='00:16:3e:5d:c7:9e'/> <filterref filter='clean-traffic'> <parameter name='IP'

Hi I am using libvirt (0.9.12) with openstack and xen. It looks like libvirt is not creating ebtables rules against arp spoofing etc. Here are my configs: VM definition: <domain type='xen'> <uuid>d49b777f-32f1-4093-ae47-a12efd0efd2c</uuid> <name>instance-00000168</name> <memory>2097152</memory> <os>

Hello, I'm recently stumbled over the libvirt network filter capabilities and got pretty excited. Unfortunately I'm not able to get the the "clean-traffic" filterset working. I'm using a freshly installed Debian Stretch with libvirt, qemu and KVM. My config snippet looks as follows: sudo virsh edit <VM> [...] <interface type='bridge'> <mac

Hello, I have a nwfilter that I'm using to ensure that libvirt domains can't spoof IPv6 traffic. It looks like this: <filter name='no-ipv6-spoofing' chain='ipv6-ip' priority='-710'> <rule action='return' direction='out' priority='500'> <ipv6 srcipaddr='$IPV6' srcipmask='$IPV6MASK'/> </rule>

After we upgraded to 1.2.12, we've been having issues with libvirt... it complains that our formerly valid guest definitions are now invalid: error: Failed to start domain XXXX error: internal error: Cannot instantiate filter due to unresolvable variables or unavailable list elements: DHCPSERVER We looked into this, and found that it's the XML validation that's failing: # xmllint
