NetworkManger creates extra bonds; is this a bug?
Hi All, I see an unexpected beahviour from NetworkManager on CentOS 7.1. Using nmcli tool, I create a bond with two slaves as explained in the Red Hat 7.1 Networking guide. I enable slaves and master; bond works as expected. When I restart NetworkManager, it creates a new bond with the same name but not connected to any device. Two bonds with the same name is confusing for my other...

...ses \via the host network > adapter, while the host retains its fixed IP. If you are running NetworkManager (the default), it's not too hard. Here's an example step-by-step for changing an existing interface "em1" to be a bridge "br0": # Create a bridge interface nmcli con add type bridge ifname br0 bridge.stp no # Copy all the IPv4/IPv6 config from an existing interface nmcli con mod bridge-br0 $(nmcli -f ipv4.method,ipv4.addresses,ipv4.gateway,ipv6.method,ipv6.addresses,ipv6.gateway con show em1 | grep -v -- -- | sed 's/: */ /') # -or- just set an IPv...

What's the difference between nmcli fields ipv4.addresses and IP4.ADDRESS?
Hi All, nmcli tool in CentOS 7.1 uses same fields with upper and lower case with different meanings. What's the difference between pv4.addresses and IP4.ADDRESS in "nmcli con show" command? Where nmcli fields are documented? I searched online but didn't find nmcli documentation. RHEL 7 Network...

ifcfg-link?
This is happening with the Centos7-armv7 image 1804, but I was wondering if it is a broader C7 issue. My image has only 2 ifcfg files:? ifcfg-l0 and -link.? 'ip a' is listing the ethernet as eth0.? ifcfg-link has contains: DEVICE=link BOOTPROTO=dhcp ONBOOT=on I then used nmcli to create my ifcfg-eth0 nmcli con delete eth0 nmcli con add type ethernet con-name eth0 ifname eth0 ip4 192.168.129.11/25 gw4 192.168.129.1 nmcli con mod eth0 ipv4.dns "50.253.254.2 192.168.129.1" nmcli con mod eth0 mac "02:67:15:00:81:0B" I moved the cable to the 192.168.129...

enp0s25 disconnect
I tried to boot a Centos 8.2 install CD, one burned with Centos-8-2-2004-x86_64-boot . In the setup, it persisted in telling me that ethernet thing enp0s25 was disconnected. Nyet. 'Twas working several seconds previous and is working now. This is a showstopper. How do I debug it? Also, whatever else it did, I now have environment variable

about the script /etc/qemu-ifup with nmcli command
Hi, I have tried the qemu-ifup script as below with nmcli command as brctl is deprecated on rhel8, but the guest network can not work. I think the script needs update. Could you please help to have a look? Thank you in advance. 1. prepare a linux bridge on the host named br0; 2. prepare the qemu-ifup script as below: # cat /etc/qemu-ifup #!/bin/bash # A...

Since there's no ifcfg file, I suspect you're using NetworkManager to manage your network. Run 'nmcli con' to get a list of your network connections, and then run 'nmcli con edit "Connection Name"' (replace "Connection Name" with the name of your ethernet connection). You can then set ipv4.ignore-auto-dns to 'yes' and then set ipv4.dns and ipv4.dns-search....

How to set macaddr with nmcli
I see my problem.? I mis-read what nmcli con mod eth0 mac "02:67:15:00:81:0B" does.? It sets HWADDR; which interface to link to, not MACADDR, what MAC address you want for your interface. So I have read the nmcli pages and googled a bit.? I cannot find a way to set MACADDR.? I suppose I can set HWADDR then use sed to change...

I think it does so and you may...

Qemu - enabling "bridge mode" for primary physical interface for VMs
I have a physical host with a single physical network adapter. I want to host several VMs on host. (guest1 - guest4) The guest systems are accessible via 192.168.122.* as is the default with qemu/virsh. There are 4 IP addresses being routed to the primary interface on host. I can set up an alias for the NIC and "see" these ip addresses. I understand that it's possible to allow
