Eduardo, As you have two hosts, I suspect the issue is related to the VLAN configuration.
The VLAN range you allocated to the guest network needs to be setup on the switch ports the Hypervisors are connected to.

I only have 1 zone (advanced/vlan/no security groups). Problem: about a third of new instances I launch seem to be "networkless". Although they have an IP assigned in the NIC page, they don't get any answer to their DHCP requests.Even if I assign a static IP to them I'm unable to to ping other instances. I've tried stopping them, restarting them, but only option is to launch a new instance. Are the instances from Ubuntu templates? If yes - is this also a problem with the VMs based on CentOS builtin template? I don't see anything out of the ordinary in the logs.
