Hello, I defined a vm with filterref like: <filterref filter='clean-traffic'> <parameter name='IP' value='192.168.1.161'/> </filterref> and now I need to add another IP parameter for this vm,is there any way to achieve this? thanks.

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'/> <source dev='em1' mode='private'/> <filterref filter='clean-tr...

...e> <rule action='drop' direction='out' priority='1000'/> </filter> The goal is to allow any traffic coming from the entire prefix (e.g. 2001:db8::/32). This theoretically would work fine when passing in the variables from the domain definition like so: <filterref filter='no-ipv6-spoofing'> <parameter name='IPV6' value='2001:db8:1:6:dc:d2ff:fef2:2181'/> <parameter name='IPV6_MASK' value='32'/> </filterref> But the problem comes when wanting to allow multiple prefixes (and thus multiple $IPV6 a...

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)....

...onestly I think the way you've done it is the right way. "clean-traffic" is best thought of as a simple demo. If it does what you need, great, but we'd expect people to create their own filters for anything more advanced. The clean-traffic rules were modularized so you can use <filterrefs> to avoid too much duplication. So what you've done looks fine to me. > [1] > <filter name='clean-traffic-gateway'> > <!-- An example of a traffic filter enforcing clean traffic > from a VM by > - preventing MAC spoofing --> > <filterr...
