Having issues figuring out networking

[Red Squirrel]

I'm trying to figure out networking but running into issues.

So the node has two NICs, ens32 is management, connected to my management vlan, as a regular connection. Ens34 is a trunk port to the switch. So I tried to follow various tutorials on how to setup the vlans, but no matter what I did, I could not get any vlans to show up as an option when assigning an interface to a vlan. I only see the physical nics as an option. If I pick the physical nic and then assign the vlan within the vm, the vm sees nothing. It doesn't get an IP or anything (I have dhcp running on the vlan I tested with)

Through deleting and trying stuff and overall trying to figure this out, I seem to have bricked the networking. I get this error now when I try to save, even a basic config.

In this particular config I'm just trying to restore it back to what it was before I played with it, and it won't let me go back anymore.

Running ifreload -a -d seems to have fixed it. Without -d I was getting these errors but -d somehow fixed it.

I just want to be clear though, by setting the vmbr1 (vlan aware) trunk interface on a vm, and specifying the vlan at the vm level, the VM is still only seeing that vlan correct? Ex: The VM OS is not seeing a trunk prt, but is equivalant to being plugged into an ethernet switch with a port set to that vlan? I just want to make sure I'm doing this right from a security perspective. I'm used to the vmware way where you need to create individual vlan interfaces too so want to make sure I'm not suppose to still do that for Proxmox as well.
