There is an ongoing discussion in the background between the maintainers for more then a year how to get rid of the hw-id node in general and do such a detection once during initial boot.

And similar example, using same interfaces and host, but instead of GRE tunnel, using a Wireguard site to site tunnel:

Example of using flowtables on mater interfaces, and communication between a local host that is on a VLAN (vlan eth2.22 and host 10.22.22.222), and a remote host that is reachable through a GRE tunnel (tunnel established using interface eth0):

By looking at this and the documentation, I do not see any proofs that flowtables support any encapsulation except VLAN and PPPOE.

Can you try with newver version?

Ok, that makes sense. Still need to place the tag.

Not all targets have username/password
For example for the future "location"

set system config-management commit-archive aws authentication access-key
set system config-management commit-archive aws authentication secret-key
set system config-management commit-archive aws bucket <my-bucket-name>
set system config-management commit-archive aws path '/'

This way, predefined targets are more preferred.

@peter, did you try various offloading settings for the NIC being used with reboots in between?

Packet drops are still an issue with XCP-ng 8.2.1 and the latest rolling releases, e.g. 1.5-rolling-202404290019. Roughly 7% of pings are dropped and TX-DRP is nonzero. The same rolling release works flawlessly under Proxmox without any TX-DRP show in netstat.

The format I started playing with looks like this:

set system config-management commit-archive 1 username 'xxx'
set system config-management commit-archive 1 password 'xxx'
set system config-management commit-archive 1 scheme 'scp'
set system config-management commit-archive 1 location '192.0.2.1/backup'

Adding additional PR to add bonding.py to op-mode-standardized.json: https://github.com/vyos/vyos-1x/pull/3408

What about this format?
We still have named/predefined targets (scp|ftp|sftp|http|https) and <name> as tag

set system config-management commit-archive target scp <name> authentication username 'xxx'
set system config-management commit-archive target scp <name> authentication password 'xxx'
set system config-management commit-archive target scp <name> server '192.0.2.1'
set system config-management commit-archive target scp <name> path '/'

need configuration index too or maybe name
so we can have several destinations for same protocol

I already looked a bit into it. What complicates it is the old location is a multi and one can add a list of locations.

Should be fixed after rewriting commit-archive T6304

NETNS was removed from the 1.4 series the other day so hopefully that feature can be worked on for 1.5 since its needed:
