Hello Prajith, 

Can you elaborate better what are you trying to achieve? 

ifdown brings the interface down but it will not remove it. ovirtmgmt is a 
bridge "interface". list your bridges with `brctl show`. 

You can remove this bridge using `brctl delbr ovirtmgmt`. And yes, network 
connectivity will be gone because the IP is on the bridge as you can see on 
your output. 

You can configure your regular interface (eth0) with the IP that's on the 
bridge now, and that should do the trick. nmcli/nmtui are your friends or edit 
/etc/sysconfig/network-scripts/ifcfg-* files manually. 

Best regards, 
Wagner Sartori Junior

Subject: [ovirt-devel] How to remove ovirtmgmt network interface in centOS 

Hey everyone, 
Could someone please point me in the right direction?. 

Im unable to remove network interface ovirtmgmt, commands like ifdown results 
in a state where the ip is unreachable and a manual network restart had to be 
done to bring it back to normal. 

could someone help me with removing ovirtmgmt network in centos?
