Hi, i want to disable the nwfilter functionality of libvirt. It's surely nice for some people, nevertheless i don't want libvirt to alter any netfilter rules, neither i want the according functionality even available. I know about nwfilter-undefine, but what i'm looking for is an option to globally disable this functionality at all. Some config flag or similar. How can i achieve

I'm trying to determine if it's possible to edit/attach/apply nwfilter rules at runtime? I.e., after a VM is already running, can I apply a nwfilter to the VM and have it work without rebooting the machine? Thus far, I've not come across a way to do so, but I thought I'd ask here before I chase my tail around Google. Thanks! -- Andre Goree -=-=-=-=-=- Email - andre at

Hello! I just spent the last four days working with nwfilters only to decide that they are apparently unusable. I've come to the mailing list seeking input on this subject. First off, please forgive my offensiveness. I'm sure people worked hard on nwfilters and it looks like a lot of effort went into providing this functionality. This is also an...

Hi all, I'm trying to install libvirt for xen on a brand new, minimal installation of CentOS 7.5.1804. After installing the OS, I did a 'yum update' and followed the basic how-tos at https://wiki.centos.org/HowTos/Xen/Xen4QuickStart and https://wiki.centos.org/HowTos/Xen/Xen4QuickStart/Xen4Libvirt From previous experience, I know that the above steps worked fine. However,

Let's say I have some iptables rules defined to restrict guest traffic. If I restart the hosts firewall 'service iptables restart', all the guest-specific rules get blown away. Is there a way to reapply all the guest firewall rules, without restarting each individual guest? It looks like if I edit a nwfilter with `virsh nwfilter-edit` it goes and reapplies the rules to all the

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>

I'm trying to apply a nwfilter rule for two networks on the same guest interface, like so: ~ # virsh nwfilter-dumpxml 1081532-private-both <filter name='1081532-private-both' chain='root'> <uuid>16004b94-2b62-4568-9467-169908eb4040</uuid> <rule action='accept' direction='in' priority='500'> <ip

Hi all, I'm unable to upgrade my Dom-0 from CentOS 7.5 to CentOS 7.6 with the sigvirt centos-xen-48 repository enabled and Xen components enabled. It breaks down to down to the fact that 7.6 has a newer version of libvirt included (4.5), while the Xen repository's packages are build against 4.1 version of libvirt. I also tried to enable the libvirt-latest repository, but that does not

Hi, I contact you as i have difficulties to use nwfilter with KVM host. I want to implemente flow filtering between my Linux guests. I created the following filter : cat admin-dmz-internet.xml <filter name='admin-dmz-internet'> <!-- this zone is an SSH ingoing only zone --> <!-- but SSH can go to an other SSH proxy --> <filterref

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 All, I have two kvm guests running with a bridged configuration bound separately to br0 and br1 on my Fedora 15 host. I'm attempting to create some nwfilter rules on br1 and am running into a bunch of problems that have me scratching my head. libvirt version: 0.8.8-7 What I've noticed on the second host is as follows: - Most all nwfilter rules that I create for the host on br1
