Thanks man ;).
By any chance if a system VM does not get its ip assigned, would there be
any way to debug and check what is going on? I mean, if after it is running
on the physical host it does respond on the IP that was assigned to it.
I say check the agent's log (set to debug!) and try to SSH into the SSVM
with the cloudstack-ssh command.

Hi folks,
I was wondering how a system vm gets an IP address. I know they are the
first things that CS needs in order to start up others VMs, so when they
start there is no virtual router to assign IP addresses via DHCP.
Via a local virtio socket from the hypervisor in KVM mode. The VM boots
and via that local serial socket it gets the IP-address.
I also noticed that on the physical hosts with the VM.Start command CS
sends some extra data that includes the IPs that the VM should get.
However, I have no idea how it actually gets those parameters and set its
IP.
The management server sends this information to the KVM agent. User
Instances get the IP address via DHCP from the VR, System VMs via the local
serial socket.

Does anyone here know how it works?
