10 (Optional) On the IPv6 settings page, select an option for obtaining IPv6 addresses.
Option Description
Obtain IPv6 addresses automatically
through DHCP
Use DHCP to obtain IPv6 addresses. A DHCPv6 server must be present on the
network.
Obtain IPv6 addresses automatically
through Router Advertisement
Use router advertisement to obtain IPv6 addresses.
In ESXi 6.5 and later router advertisement is enabled by default and supports the
M and O flags in accordance with RFC 4861.
Static IPv6 addresses a Click Add IPv6 address to add a new IPv6 address.
b Enter the IPv6 address and subnet prefix length, and click OK.
c To change the VMkernel default gateway, click Override default gateway for
this adapter.
The VMkernel Default Gateway address for IPv6 is obtained from the selected
TCP/IP stack.
11 Review your settings selections on the Ready to complete page and click Finish.
After you create a VMkernel adapter on the provisioning TCP/IP stack, you can use only this stack for
cold migration, cloning, and snapshots on this host. The VMkernel adapters on the default TCP/IP stack
are disabled for the provisioning service. If a live migration uses the default TCP/IP stack while you
configure VMkernel adapters with the provisioning TCP/IP stack, the data transfer completes successfully.
However, the involved VMkernel adapters on the default TCP/IP stack are disabled for future cold
migration, cross-host cloning, and snapshot sessions.
Limits on Simultaneous Migrations
vCenter Server places limits on the number of simultaneous virtual machine migration and provisioning
operations that can occur on each host, network, and datastore.
Each operation, such as a migration with vMotion or cloning a virtual machine, is assigned a resource
cost. Each host, datastore, or network resource, has a maximum cost that it can support at any one time.
Any new migration or provisioning operation that causes a resource to exceed its maximum cost does not
proceed immediately, but is queued until other operations complete and release resources. Each of the
network, datastore, and host limits must be satisfied for the operation to proceed.
vMotion without shared storage, migrating virtual machines to a different host and datastore
simultaneously, is a combination of vMotion and Storage vMotion. This migration inherits the network,
host, and datastore costs associated with those operations. vMotion without shared storage is equivalent
to a Storage vMotion with a network cost of 1.
Network Limits
Network limits apply only to migrations with vMotion. Network limits depend on the version of ESXi and
the network type. All migrations with vMotion have a network resource cost of 1.
