This section describes the network-related issues in Oracle Solaris 11.4.
You cannot configure a Datalink Multipathing (DLMP) aggregation on an SR-IOV NIC virtual function in a guest domain.
When a zone is running inside a guest domain and the zone is allocated one of the domain MAC addresses, migrating the zone to another guest domain might cause networking to silently fail. The MAC address is allocated by using the following command:
# ldm set-vnet alt-MAC-addrs
Network failure occurs when the same MAC address is configured on the destination guest domain, both the guest domains are on the same physical host, and both domains share the same virtual switch configured on the control domain. This failure applies to cold migration of zones and live migration of kernel zones.
Workaround: Migrate to a guest domain on a separate physical host. Otherwise, if the migration is already complete, halt the guest domains, unbind and rebind them, and boot the guest domain. This process resets the networking configuration and enables the zone networking to function again.
