[PVE-User] A problem getting DNS configuration up on debian cloud-init images

[Simone Piccardi]

Hi,

I'm having some problem getting DNS configuration for debian cloud 
images, the one published here:

https://cdimage.debian.org/cdimage/openstack/

I used the current debian-9.7.0-openstack-amd64.qcow2 imange, importing 
it following https://pve.proxmox.com/wiki/Cloud-Init_Support. I used it 
directly (not cloning from a template), because I needed some 
modifications (root login by SSH).

The problem I got after setting an IP address and gateway ans starting 
the VM, is that the network configuration in 
/etc/network/interfaces.d/50-cloud-init.cfg will put the dns-nameservers 
declaration under the lo interface with something like:

auto lo
iface lo inet loopback
     dns-nameservers 213.133.100.100 213.133.98.98 213.133.99.99

auto eth0
iface eth0 inet static
     address 192.168.77.44
     gateway 192.168.77.1
     netmask 255.255.255.0


but this way resolvconf will not setup resolv.conf. Not sure where the 
problem lies, but why do not usemanage_resolv_conf ?


Regards
Simone
