Hi, Referring to the link http://wiki.libvirt.org/page/VirtualNetworking, the scenario described for the routed mode, explains that "Host has public IP and virtual machines have static public IPs. But one can't use bridged networking, since provider accept only packets from the MAC address of the host" Can someone explain to me why doesn't the s...

Hi, I am referring to the 'Routed Mode' section just under the section 'Other virtual network switch routing types' in the URL ' http://wiki.libvirt.org/page/VirtualNetworking#Routed_mode'. In the above link, for routed mode, it is stated that 'In this mode all virtual machines are in a subnet routed through the virtual switch.' Can anyone explain to me, if the guest machines have to be in the same subnet as the Host machine for the routed mode to work (o...

Hi Every one, I'm hoping some one can point me in the right direction. We are piloting KVM + Libvirt for migrating off Xen and I'm stuck with the network bridge configuration via libvirt. What we have currently with xen is: 1 server with Wan/lan interfaces and a pool of public ip addresses. Using xen bridge scripts I'd start a xenbr0 and attach eth0 (wan) and go ahead and assign

HI, I've just begun using libvirt as part of my KVM installation and have been having some confusion regarding networking of my virtual guests. I'm not sure if I should even be sending this to this mailing list and if not please let me know and if possible where I should be sending this inquiry. I understand I can setup a dedicated bridged interface for my guest. But as for the virbr

...ing that a NAT'd guest network is most likely something that I do not want. I have some choices on how to configure each guest network, it could be an "open <https://www.redhat.com/archives/libvir-list/2016-August/msg00640.html>" or "routed <https://wiki.libvirt.org/page/VirtualNetworking#Routed_mode>" network, but I would still need to configure some static routes. I will take a stab at doing an open or routed network today, but in the meantime, your thoughts and comments about my setup are still welcome and encouraged. Thank you! -Cobin On Wed, May 30, 2018 at 10:4...

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 Libvirt Users, I would like to setup a two node bare-metal cluster. I need to guidance on the network configuration. I have attached a small diagram, the same diagram can be seen here: https://i.imgur.com/SOk6a6G.png I would like to configure the following details: - Each node has a DHCP enabled guest network where VMs will run. (eg, *192.168.1.0/24 <http://192.168.1.0/24>* for
