Bug#867594: cloud.debian.org: vms lease the same dhcp ipv4 address in kvm/libvirt
Package: cloud.debian.org
Severity: important
official debian/stretch64 v9.0.0 vagrant box has wrong dhcp configuration.
As far as I understand, Stretch switched to using DHCP Client Identifier (DUID)
by default, which is generated from /etc/machine-ip, which should be different
due to installation procedure. As Vagrant boxes have no regular installation
procedure, machine_id is embedded into the box, and so, is the same for
all vms and Client Identifier also. As libvirt uses that DUID for assigning
IPv4 addresses, all stretch vms get the same initial IP - new one
makes unusable all previously started.
As DHCP client has an option to use MAC for DUID (or instead DUID?), I propose
to update network config inside vagrant box to use MAC.
