Networking

The Phoenix lab has several networks used for various purposes.

Name	VLAN ID	Subnet	DNS suffix	Description
DMZ	91	66.187.230.0/25	phx.ovirt.org	Internet-facing, used for external services
guest	92	209.132.185.0/24	guest-phx.ovirt.org	Internet-facing, used for various unrelated services
storage	913	172.19.10.0/24	-	storage network, isolated (no access to Internet or other nets)
infra	911	172.19.11.0	infra-phx.ovirt.org	hypervisors are located in this subnet
workers	912	172.19.12.0/22	workers-phx.ovirt.org	Jenkins slaves reside in this subnet

Only the DMZ and guest subnets are reachable from the Internet. Systems from other subnets are behind NAT served by a dedicated gateway VM, gw01.phx.ovirt.org which also provides DHCP, DNS and OpenVPN services for these subnets. DHCP and DNS for the DMZ is provided by foreman.phx.ovirt.org. To connect to systems in internal networks, use any system from the DMZ network as a jump host or set up OpenVPN.

Note: DNS for the upper level ovirt.org zone is managed by Red Hat IT. To apply changes to it an internal support ticket mut be opened by a Red Hat employee.
