Subject: [PATCH] feat(proxmox): add datanet NIC provisioning script for
 k8s+ultix VMs
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Adds second virtio NIC (net1) to all k8s nodes and ultix VMs, bridged to
the VLAN 1000 storage network. Handles both bridge names (datanet on most
hosts, storagenet on tsys6). IPs tracked in phpIPAM (10.100.100.10-19).

+# add-datanet-nics.sh
+#
+# Adds a second virtio NIC (net1) to all k8s + ultix VMs, bridged to the
+# storage/datanet network (VLAN 1000). Records the assigned IP in phpIPAM.
+#
+# Runs from the workstation — uses tests/remote.sh to reach each hypervisor.
+# Hot-adds the NIC (no VM downtime). Guest-side IP config must be done
+# separately (the guest OS needs the IP configured on the new interface).
+#
+# Usage:
+#   bash add-datanet-nics.sh             # add NICs (hot-add, no reboot)
+#   bash add-datanet-nics.sh --status    # show current state only
+#
+# IP allocations (phpIPAM VPTechOps, subnet 10.100.100.0/24):
+#   .10 = cnode1    (102/tsys1)
+#   .11 = cnode2    (705/tsys7)
+#   .12 = cnode3    (603/tsys6)
+#   .13 = wnode-tsys3 (313/tsys3)
+#   .14 = wnode-tsys5 (500/tsys5)
+#   .15 = wnode-tsys6 (601/tsys6)
+#   .16 = wnode-tsys7 (701/tsys7)
+#   .17 = wnode-tsys9 (905/tsys9)
+#   .18 = ultix-streaming (5111/tsys5)
+#   .19 = ultix-offstage  (5112/tsys5)
