KVM config problem with bridge

[roberto.schiano]

NethServer Version: 7 final
Module: KVM

Hello everyone.
I lost the server …
I tried installing a virtual machine, as I wrote in the manual I created a bridge logic network card, gave it an ip and after restart I see nothing more …
Configuration: Network adapter NetH 7 192.168.1.10 + br0 for active directory (192.168.1.11) Ok.
After add br1 (192.168.1.12), nothing is seen again. Help

Hello @roberto.schiano,

when I remember correctly you may use the same bridge(green br0) for the VMs that is used for ad, so you don’t need another bridge br1.

Docs:

OK perfect. I did not know this WIKI.
But I have already done the new bridge and the server is no longer reachable …
Now, how do I disable br1, I can do only in the console, I dno’t know, I’m not familiar with CentOS.
Thank you

You may completely reset your network configuration and start over:

how do I disable br1

Hi,
I’ve found something

# ip link set br100 down
# brctl delbr br100

at the following site, but not tested.

Bring down and delete bridge interface that's up

[roberto.schiano]

with these commands. not solved

[roberto.schiano]

Made to the letter but nothing. after the “signal-event system-init” command, everything returns as before …

[roberto.schiano]

Fixed with VI editor, I edited the “ifcg-ethxx” configuration file, modified the br1 br1 voice edit in br0 and the server came back available.
