I am struggling to create a virtual machine with UEFI and working networking. I have multiple virtual machines with the default SEABios that can connect fine, with DHCP, even during the installs. However, when I create a q35 machine with UEFI, and pre-enrolled keys unchecked, I cannot connect to the network. This includes trying to assign addresses in the VM statically. It seems like a host issue, considering all SEABios VMs have no issue.
 
Hello,

Have you tried to disable the secure Boot in the UEFI settings of the VM?

Can you please provide us also with the output of `pveversion -v` and `qm config <VMID>`?
 
I have misdiagnosed the issue. I performed some checks before collecting the information above. I have two interfaces, and one interface was off in proxmox. This interface was for VMs, not for the web GUI. After checking the cables, and restarting proxmox, all interfaces are back up and both SEABios and UEFI machines have network connectivity. Thank you for your reply!
