Hello all, I’m currently trying to figure out how to forward ports to guests that are on a NAT Network. I have followed the directions on https://wiki.libvirt.org/page/Networking under the “Forwarding Incoming Connections” Section and get connection refused when attempting to connect. System: Ubuntu Server 18.04.1 Virsh / LibVirtd Version: 4.0.0 Here’s the contents of /etc/libvirt/hooks/qemu  

This is a continuation of the thread about redhat vs centos and the thought of moving from centos due to redhats new business model. Forgive the length, but I had to share. I went ahead and downloaded the 5 year supported version of ubuntu server. You think centos/redhat is a bit tough or not polished? One day with ubuntu server and you will look at centos install and setup as a god! Where do

inquiry about differences between the tap and the vnet in the virt-manager Greetings!

Hi, I am an experienced libvirt user on Fedora versions from F15 to F17. I have developped scripts to route trafic from outside on multiple interfaces/multiples IPs to multiple VMs, and back to affect each VM the required external IP address. I have servers with more than hundreds external IPs, and up to 4 VMs, each of them route trafic on different external IPs. I have servers with Fedora

Hi everyone. Those are the iptables forwarding rules associated with the two virtual networks on my machine: ----------------------------------------------------------------------------------------- -A FORWARD -d 192.168.100.0/24 -o virbr1 -m state --state RELATED,ESTABLISHED -j ACCEPT -A FORWARD -s 192.168.100.0/24 -i virbr1 -j ACCEPT -A FORWARD -i virbr1 -o virbr1 -j ACCEPT -A FORWARD -o

hi everybody I have a simple network: <network> <name>default</name> <uuid>1e71fa47-4893-4435-8b60-575d2b51c231</uuid> <forward mode='nat'> <nat> <port start='1024' end='65535'/> </nat> </forward> <bridge name='virbr0' stp='on' delay='0' /> <mac

Running CentOS 6 I have noticed that Libvirt will automatically configure IPtables once a VM is using the built in NAT , or "default" network. How do I modify the IPtable rules without breaking libvirt's ability to configure these rules? This is the firewall settings on a fresh install with no VMs using virbr0... -------------------------- Table: filter Chain INPUT (policy ACCEPT)

I've got a Centos guest and a Windows 2003 server guest running in Xen under Centos (5.2 in both cases), and they can get out to the network, and I can ping them from dom0. This is my first Xen install, and I haven't used Linux as a router before (I'm very familiar with it as a webserver and development platform) so I'm a bit weak on the bridging code and NAT / IP masquerading.

Hello, I'm a little confused on which networking option I need to choose when setting up a VM. I set up two VMs this past weekend both with NAT. Both able to were access the internet. The first one, I created in my / file system but didn't really have the space so I deleted it. The second one, I created in /home/kvm, but deleted it as well when I couldn't access it FROM the

I just wrote this to assist some Red Hat folks understanding what libvirt does with iptables, and thought it is useful info for the whole libvirt community.

Hi! I want to forward the port 3389 from the domU to the virtual server with ip address 192.168.122.77 with not success... I tried a lot of iptables rules with no luck so far. Is this possible?

Dear libvirt users, I am encountering problems with network connections from VMs while running net-update on the host. I would be very grateful for suggestions of fixes or workarounds. I am using libvirt in the context of an automated test system which creates and destroys VMs fairly rapidly, hence network updates occur often. ## Reproducer The issue can be reproduced as follows. Run in a VM:

I need some help in understanding libvirt's virtual networking. I have configured bridged networking (shared physical device) on libvirt+KVM system which is working fine. Also, I am using default NAT network on with virbr0 bridge device and virbr0-nic. I would like to get better understanding on virbr0-nic works in this virtual network configuration. I understand that traffic from virbr0
