Hello, I came across an interesting problem in my home lab a few weeks ago as I'm prepping for my RHCE exam using Michael Jang study guide. I've been at this for days now, and I still can't wrap my head around how two or more virtual networks in default NAT configuration are even allowed to communicate with each other despite what the libvirt documentation said. Here's the

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

I am running Fedora 16 64bit and installed libvirt. I have the VM running with arm emulation with this one issue I can't figure out. I used Virtual Machine Manager to manage the VM and can access its console there. The Ethernet appears to be eth1 and the guest can set an IP on it etc. However, I cannot see any traffic from the Host when dumping any of the interfaces. I've tried

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

Hi all, I have 3 guests (2-RHEL4 and 1 RHEL6) and have some issues regarding networking between them. The 2 RHEL4 system's use default bridge virbr0 and get ip's of range 192.168.122.0/24 (192.168.122.207, 192.168.122.167) I created another bridge (virbr1) with NAT forwarding (no dhcp). The network i choose was 192.168.100.0/24. And the third system (RHEL6) was assigned static ip-addres

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  

Just created the first completely new Xen VM with the Virtual Machine Manager after 5.0 became 5.1 and I notice these two differences: - there's now virbr0 instead of xenbr0. Which means I have now xenbr0 and vitbr0 interfaces running. As virbr0 just the new name for xenbr0? If so, can I just change that name in the older configuration files, so that all use the same interface name? -

This is fresh install of CentOS v6 and Xen v4.1 on a new Dell server following the tutorial posted at: http://wiki.xensource.com/xenwiki/RHEL6Xen4Tutorial   Every thing went just fine, yet virbr0 won''t work and when I run brctl show I get the following error message:   [root@pe1950 ~]# brctl show bridge name     bridge id               STP enabled     interfaces virbr0

I actually opened the Virtual Disk Image (.vdi) on http://www.vmxray.com/. I could see that despite my disk being of 100GB only ~65GB was being shown. All the stuff related ot the local user was not visible at all. After I restarted my VM, the OS gets stuck here ( http://i.stack.imgur.com/KVYxV.png). Even after trying the single user login it was stuck there. But the emergency mode worked alright.
