Title:
hv_set_ifconfig script don't check dns is empty when add this
information to network interface.
Status in linux package in Ubuntu:
Confirmed
Status in linux-azure package in Ubuntu:
New
Bug description:
When trying to configure a virtual NIC using Hyper-V's integration services
with no dns entries.
The script will add a line "dns-nameservers" with no arguments (you can see
that in attachment file) into network/interface.
So when we restart network the new configure of virtual NIC can't apply.
