VM's on br0 cannot access the internet after 6.12.0

I resolved this issue by changing my network model for my VM's from 'virtio-net' to 'virtio'

 

Does anyone know why virtio-net does not appear to work anymore?

This did not resolve the issue for others and stops working after an unRAID restart.

Turns out the problem was actually with my network settings, when I restarted my unRAID server, the network connections stopped working again for both VM's. To resolve it I discovered that under network settings I had to enable bonding for eth0.

I enabled bonding for the NIC, set the mode to backup and only included eth0 in the bond.

After starting the VM's again, their network connections started working and the connections continued working after an unRAID restart.

Hi, 

 

think I am having the same problem, but not certain as I have only tried setting up a VM this weekend, after I had already updated to 6.12. So I've not yet been able to get it running at all, I checked my network settings and bonding appears to be on already. Do these settings look correct for what you guys used to get it working again?

Just ran into this issue myself, the above fix unfortunately did not apply.

I already had bonding setup. I was able to get it working by swapping my VM over to virt0 for now. But that means it no longer has direct visibility of my network. 

For now this works for me, I'll have to plug more at it later, but I'm thinking it might just be an issue with this version of unRAID.

Hey mate, did you get it working eventually? In the exact same spot now; unsure if I should just toss the VM if there’s no simple way to get it working.

Hi Zazer, 

 

I did not find a solution, and no one replied to either this or another post I made with a fix. To be honest I had forgotten all about it until your reply reminded me to have a look again, so I fired up the VM today and for whatever reason it now works. I have absolutely no idea why, I have not changed the configuration of anything, so I'm guessing an update to something fixed it (I haven't updated Unraid OS). Sorry I know that's obviously no help to you.

 

Cheers

Charlie
