Package: isc-dhcp-client
Version: 4.3.5-4
Severity: important
Dear Maintainer,
*** Reporter, please consider answering these questions, where appropriate ***
* What led up to the situation?
I run a virtual machine that sets its address using isc-dhcp-client.
The dhcp server is dnsmasq spawned by libvirt.
The virtual machine is assigned a static ip address 192.168.208.2 based on
its MAC.
* What exactly did you do (or not do) that was effective (or
ineffective)?
I start a virtual machine.
* What was the outcome of this action?
The dhcp client inquires for an address, it receives the address
192.168.208.2 from libvirt dnsmasq. It assigns the address 192.168.208.2
to the interface, but it also sends a "decline" message. dnsmasq responds
to the decline message and assigns a different address on next virtual
machine reboot. The result is that the virtual machine can't be reached
with the assigned address.
* What outcome did you expect instead?
The dhcp client should accept the offered address and shouldn't send the
decline message.
