Thanks for giving more details.
I will give a try with each of them (netplan, ..etc)

@olivierlambert
ok thanks for the well written explanation

hi
I didn't know if this is the expected behavior, but after completely (install and configure with added vif during setup) deploying a VM,
when i add another VIF(on debian 13 ), i noticed that the interface is created but remain down. i had to manually
edit /etc/network/interfaces and add new line specifying the new interface with options (auto and dhcp).
Is that the expected behavior?
Thanks
