Migration of VMkernel adapters is supported on transport nodes using an N-VDS or VDS host switch. In the scenario illustrated in this section, VMkernel-1 (vmk1) adapter is migrated to an N-VDS switch on a host where host profile is applied. The vmk1 adapter supports infrastructure traffic for vMotion, Fault Tolerance, and other infrastructure services.

Scenario Error Workaround
vmk1 migration on a standalone target host by applying reference host profile.

The target host is not configured as a transport node. As the target host does not know about any NSX-T objects, host profile application fails. Remediation of host profile on the target host fails.

Error: Received SOAP response fault :
 generate HostConfigTask Spec..
  1. Before applying the reference host profile to migrate vmk1 to the logical switch on the target host, configure the target host as a transport node, which installs NSX-T VIBs, creates an N-VDS switch and migrates vmk1 adapter from the VSS switch to N-VDS switch.
When configuring the host as a transport node because the host profile on the ESXi, ensure the following conditions are met:
  • Host must belong to the same transport zone.
  • vmk1 adapter must be connected to the same logical switch that is used by the reference host.
  • Target host must use the same IP pool that is used by the reference host.
  • Uplink profile, LLDP, NIOC, network mapping for install, N-VDS configured on the target host must be the same as configured on the reference host.

    Host profile remediation is successful when the target host is configured with the same logical switch name that is present in the host profile.
vmk1 migration on target hosts in a stateful cluster. Before applying the host profile to the target host, if you prepare the cluster by applying TN profile configured with vmk1 mapped to the logical switch, then vmk1 migration fails.
Error: vmk1 missing on the host.
  1. Apply the reference host profile to the target host that joined the cluster.
  2. Remediate the host profile on the target host to create vmk1 adapter on the target host.
  3. Re-apply the TN profile to the cluster to migrate vmk1 to the target cluster.
vmk0 and vmk1 migration on a standalone host. When configuring NSX-T on the standalone host, if the Network Mapping for Install field does not specify vmk0 or vmk1 mappings, then migration fails. When configuring NSX-T on the target host, ensure that the Network Mapping for Install field is specified with vmk0 and vmk1 mapped to the same logical switch on the N-VDS.
vmk0 and vmk1 migration on a cluster host. When applying TN profile to a cluster, if the Network Mapping for Install field does not specify vmk0 or vmk1 mappings, then migration fails. Apply TN profile to the cluster. When configuring TN profile to the cluster, ensure that Network Mapping for Install field is specified with vmk0 and vmk1 mapped to a logical switch on the N-VDS.
