I upgraded to proxmox 8 last night. All my VMs now can't get an ip adress from the dhcp server. Not sure how to troubleshoot this. Other appliances on the home network get ip addresses just fine.
 
- please share your PVE host "/etc/network/interfaces"
- (from PVE host) what is the output of : # ip ad
- can the PVE host reach (ping) the dhcp server?

Here:

Code: 
auto lo
iface lo inet loopback

iface enp10s0f0 inet manual

iface enp10s0f1 inet manual

iface ens4 inet manual

auto vmbr0
iface vmbr0 inet static
    address 10.1.5.33/24
    gateway 10.1.5.1
    bridge-ports enp10s0f0
    bridge-stp off
    bridge-fd 0

auto vmbr1
iface vmbr1 inet manual
    bridge-ports ens4
    bridge-stp off
    bridge-fd 0
    bridge-vlan-aware yes
    bridge-vids 2-4094


- Ouput of ip ad:

- Yes the proxmox host can ping the dhcp server successfully.

How can I rollback to v7? My network has been messed up on v8 and not getting anywhere to resolve it for a couple days now. Now, I cant even access the GUI anymore. Was available yesterday. Nothing has changed.

You can try and use one of the two Intel nics.
Maybe the Aquantia nic is not compatible with PVE8 and kernel 6.2.

I have tried all of them. The network seems to have completely disappeared. All the unifi switches are in offline mode now.

I think if there is a clean way to roll back, I'd like to do that an wait this out.
