Hi Michal, Ok. Please can you try this scenario once you get free time. Currently my hypervisor is Ubuntu 14.04 LTS 3.13.0-24-generic. Meanwhile I will try this with some other Linux kernel also.

Hi Folks: I have a strange problem with multiple (2) NICs on a CentOS 5.5 dom0 setup running xen 3.4.3 and have been struggling to fix it for some time. I could not find anything by googling or searching through this list but that is probably because I couldn''t figure out the correct search terms. After I configure my bridges the command "system network restart" fails for eth1

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

Well, for a start, if you do that then the dhcp server that is running on virbr0 will be exposed to the physical network and begin answering DHCP requests from devices out in the real world. And then you

Hi, I got this NOTE on most of the link. But I am not getting reason for this. Why someone should not add physical NIC to virbr0. I tried to add my eth1 to virbr0 and it get added. So whether it affects to some functionality of NAT network? -- Sagar Dilip Shedge, Pune. With Regards.

Hi, I have an existing fedora14 system with two interfaces and several virtual interfaces (as in eth0:0, etc). They are currently configured to not be controlled by NetworkManager, but just standard network services. I've recently started working with libvirtd, so I also have a virbr0 interface as well that has its own network and is masquerading the networking for the single KVM instance I

Hi, I have a fc14 box with two interfaces that I'm having some difficulty setting up a bridge properly. I have a few kvm guests set up and running, but I've switched from using NetworkManager to using standard networking with a bridge. I've modified the ifcfg-eth0 and created ifcfg-br0 as per the standard documentation, but I think I'm having routing problems. This is what the

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

Hi We have the following situation: A hypervisor using KVM-Qemu/libvirt with a single VM. The VM has the internal IP 192.168.122.151 on the default network pool using virbr0 on the hypervisor. We've set up netfilter rules to DNAT requests on one IP of the hypervisor to the VM. So, first of all, forwarding to the internal IP range is allowed: > $IPTABLES -I FORWARD -m state -d

Hi, I am trying to fix a problem I have for about a week now.

Hi, In my office I have an HP Proliant server running CentOS 7. It's a minimal install without GUI. The machine has two network interface cards, and for now it's acting as gateway/firewall, and it's running ntpd, Dnsmasq and Rsnapshot. I'd like this machine to also be a KVM virtualization host, so I installed qemu-kvm and libvirt. The interface facing the LAN is enp3s0, so I
