+In this figure there are examples of two virtual deploys:
+   - Jumphost 1 has only virsh bridges, created by the deploy script
+   - Jumphost 2 has a mix of linux and virsh briges; when linux bridge exist for a specified network,
+     the deploy script will skip creating a virsh bridge for it
+
+**Note**: A virtual network "mcpcontrol" is always created. For virtual deploys, "mcpcontrol" is also used
+for PXE, leaving the PXE bridge unused.

+In the baremetal deploy all bridges but "mcpcontrol" are linux bridges. For the Jumpserver, if they are already created
+they will be used; otherwise they will be created. For the targets, the bridges are created by the deploy script.

+**Note**: A virtual network "mcpcontrol" is always created. For baremetal deploys, PXE bridge is used for
+baremetal node provisioning, while "mcpcontrol" is used to provision the infrastructure VMs only.
