[pve-devel] rfc : pve-network : idea to generate and reload config accross the nodes

[Alexandre DERUMIER]

Hi,

I have thinked about a way to generate config and reload it to differents nodes


"

make changes in /etc/pve/network/*.cfg

at datacenter level, network panel , click button ->verify config,
this create a 
/etc/pve/nodes/<node>/.networkconfigstatus for all nodes (with something like verify:pending)

each local node (daemon) will generate the configuration and validate if they are no conflict/error 
The ok/error with message will be stored in .networkconfigstatus  (verify:ok)

Reporting of status of all nodes is displayed at datacenter level.


If all nodes verification state are Ok, we can click a button "apply config",

then local daemon apply configuration and reload.
status ok/error is reported in /etc/pve/nodes/<node>/.networkconfigstatus

"

I think it's better than blindly try to reload networkconfig on each change, as network is critical,
and sometimes admin need to change multiple parameters and apply it once.


What do you think about this ?
