IPAM + VM Configuration

[wajwuz]

Is there an existing feature request for this?

• I have searched the existing issues before opening this feature request.

Describe the feature you would like to see.

Support for IP's over DHCP (MAC address), MTU setting for VM's.

Describe the solution you'd like.

Convoy doesn't support IP's over MAC address from DHCP network also if someone is tunnelling his IP's he might have lower MTU than 1500 but Convoy overwrites this even VM template has all this setup correctly.

Additional context to this request.

No response

I can make it so that Convoy doesn't override configuration, but you're going to have to elaborate about support for IPs over DHCP. It's not clear whether it is possible through Proxmox's API to do this.

[wajwuz]

I think adding option MTU while adding node would be great and when it's empty it will use default value 1500.

And here's the option I talked about:

• First is "Bandwidth limit" which is rate in PVE

• Second is "MTU" which convoy overwrite by default and I had to manually change the code.
  ^ Screenshot above

• Third is "Setting only MAC address on IPAM". Currently we need to provide: IP, GW, CIDR which we can replace by MAC addresses with DHCP. And this is because Netplan on Ubuntu doesn't like gateways outside the subnet of allocated IP, for example: 1.2.3.4/32 and gw: 4.3.2.1. Maybe there should be and DHCP option with -- input MAC address

Also I found this:

Which can be located at PVE API: https://pve.proxmox.com/pve-docs/api-viewer/index.html#/nodes/{node}/qemu POST

Should MTU be set depending on the network interface or should all VMs in a node have the same MTU? I'm looking for what's the best way to implement this.

[wajwuz]

Yes, MTU should be inherited from network interface.

But convoy should not override if something custom is set already in proxmox.

Well that would be a bit hard to tell if a value was set by a user or was supposed to be overridden.

You could set it during installation, and not override every few seconds (not like the network speed thing)

The rate limiter currently only sets the network speed in the latest release.
