I have an init program that configures the eth0 interface with an IP and gateway when the container starts.

hello i have a server colocated in a datacenter with several external IP addresses available to use. the physical server is using one of these IPs, and i want to assign another, unused IP to the virtual machine. i thought i could just do this by editing the container's /etc/network/interfaces, setting a static IP address for eth0 much like i did for br0 on the host machine.... but doesn't

I have CentOS 7 host. Two guests on bridge network setup by GUI and virt-manager. 1 CentOS 8 guest 1 Win 10 guest Both cannot access the host. They can other machines on the network. Guests can access the internet just not the host. I used virt-manager GUi to set up everything. Selected the eth0:macvtap and Bridge. I "desire" bridge network. If I select something else I get access to

Hi Cole I tested the LXC VM with libvirt 1.2.12 after applying the patch http://www.redhat.com/archives/libvir-list/2016-April/msg00505.html I'm now getting following errors.. virsh -c lxc: start test error: Failed to start domain test error: internal error: Unsupported network type ethernet I'm using the below XML file for launching LXC VM.. <domain type="lxc">

Thanks Cole. I need to use network type="ethernet" with LXC instead of Qemu. I have reopened my bug.

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

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

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 Hi list, I searched the web for bug reports regarding this phenomenon I see on *multiple* machines of a customer, however, I didn't find an exact fit. So, I'd like to ask here whether anyone else has run into this. I have multiple CentOS 6 machines running using KVM to virtualize a bunch of machines on them (LVM-based). Software releases
