Hey guys not sure why but ive changed the bridge method for eth0 to the following (see pic below) but since doing so it has broken the network on the VMs. previously the VMs were set to virbr0 but the VMs cannot find the network anymore, i've change it to br0 but still nogo, I dont have any other network options in the VM config.

so apparently i lost my virbr0 interface when i reconfigured the nics?

is there a way to manually rebuid the virbr0 interface? 

so here is my current network.cfg

i looked at my old in but dont see any mention of virbr0 

no error in the VM logs

 
it just dont want to connect, even with a static IP 

 

been messing with it all day today.. still zero success. any recommendations? 

You reset the network settings by deleting/renaming network.cfg and network-rules.cfg (if it exists), both will be on flash/config.

i did that sir and still no luck. 

You likely have other issues as that would reset all network settings.

virbr0 is a virtual network created by libvirt (VM manager) and has nothing to do with network settings.

 

Please provide diagnostics.

 

here you go sirs

Your diagnostics show virbr0 is present.

Try to re-assign the interface in your VMs

oh wow.. didnt see that. i wonder when i did the Unraid Nvidia  plugin and did the OS upgrade then OS swap to the Nvidia Plugin one if it reinstalled it? this is what i see now under network settings 

 

before virbr0 wasnt there.. see above screenshot. now i need to change it to 192.168.1.0/24 because its not getting any traffic still. 


edit:  nope all good. it had the static setting in there from trouble shooting. changed to DHCP and its working we have web again!! 
thx
