Adding / changing uplinks in vs0 virtual switch configuration failed at nutanix single node cluster

The update of a virtual switch vs0 failed at nutanix single node clusters because the cluster is unable to perform a rolling reboot. You have to convert the switch and change the uplinks via the old manage_ovs commands and convert it back:

1. Disable the cluster VS(No downtime)
1. acli net.disable_virtual_switch
2. Then upgrade the bridge via the CVM with the correct details:

1. Uplink with LACP:

                                                              i.      manage_ovs --bridge_name br0 --interfaces <interface names> --bond_name br0-up --bond_mode balance-tcp --lacp_mode fast --lacp_fallback true update_uplinks

2. Uplink without LACP:

                                                              i.      manage_ovs --bridge_name br0 --interfaces <interface names> --bond_name br0-up --bond_mode <active-backup/balanced-slb> update_uplinks

3. Then verify connectivity to the CVM and AHV host
4. Migrate the bridge back to a VS:
1. acli net.migrate_br_to_virtual_switch br0 vs_name=vs0
