similar to: domU packet forwarding

Hi all, my dom0 is centos5.2 and domU paravirtualized is centos5.1 I can play sound on dom0 but not in domU (name: gasphar), moreover I use wifi as my inet connection and on installing domU cento5.1, I used virt-manager. I know that libvirtd made virbr0 and when changing to xenbr0, I cannot connect to internet but ssh to dom0 is fine! so how do I enable sound device on domU and changing to

Thanks for the reply! output: net.ipv4.ip_forward = 1 What do you mean "The out:any and" Anywhere else I can look as to why the connection isn't going? Do I need some kind of listener at that port on the host? I'm not even seeing the packet count on the prerouting chain increase when the connection attempts are made.

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  

I just did a fresh install of centos 5.0 from cd, followed by yum update which installed 399 packages. No failures or errors that I can see. I have three nics in the box, but am only setting up one at the moment. The box can ping others in my network, but if I try ssh, telnet, ftp, etc I get this: [root at cm network-scripts]# ftp watchdog ftp: connect: No route to host ftp> [root at cm

At work I have a script that provisions a vm for use by employees. One step in this process is to fetch hadoop, which we happen to get from cloudera. I noticed the script always failed when I used libvirt's default networking (nat) but worked fine when I used user mode networking. My instinct is that this is related to (potentially uncommon) network traffic from the server in question, and

Hi, I am running a webserver on the libvirt host and would like to add a nwfilter such that a VM can access that server. The corresponding iptables rule would look like this: iptables --append INPUT --in-interface virbr0 --destination 192.168.122.1 --protocol tcp --dport 80 --jump ACCEPT where the network is using virbr0 and sits at 192.168.122.1. I don't want to hardcode the host IP

I am running Xen on a RHEL4 dom0 and have two RHEL4 domU''s. The domU''s are both running Oracle 10g R2 database. I want to connect to these databases from another computer. Xen is set up with NAT network and all dom''s have access to the internet and they can ping eachother so the network is up and running. My problem is that I cannot connect to the different oracle

Hi, I just migrated my office's server from Slackware64 14.1 to CentOS 7. So far everything's running fine, I just have a few minor details to work out.

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? I take a look at other post and I don''t found an answer. By example: /sbin/iptables -t nat -A PREROUTING -p tcp -i xenbr0 --dport 3389 -j DNAT --to 192.168.122.77:3389 the virtual nic for the

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'm having some port forwarding issues issues with iptables. We are using iptables as a firewall with 2 nics and on ip alias.

Hi. I have a machine with a local DHCP server and a couple of virtual networks and I've configured the server for each virtual interface, so that I would be able to install VMs on the corresponding subnets using PXE. The problem is that the two DHCP servers (my local server and dnsmasq) are conflicting with each other causing the boot process to either fails or takes ages untill a VM can
