8 (Optional) On the IPv4 seings page, select an option for obtaining IP addresses.
Option Description
Obtain IP settings automatically
Use DHCP to obtain IP seings. A DHCP server must be present on the
network.
Use static IP settings
Enter the IPv4 IP address and subnet mask for the VMkernel adapter.
The VMkernel Default Gateway and DNS server addresses for IPv4 are
obtained from the selected TCP/IP stack.
9 (Optional) On the IPv6 seings 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.
Static IPv6 addresses
a Click Add to add a new IPv6 address.
b Enter the IPv6 address and subnet prex length, and click OK.
c To change the VMkernel default gateway, click Edit.
The VMkernel Default Gateway address for IPv6 is obtained from the
selected TCP/IP stack.
10 Review your seing selections in 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 congure
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 satised for the operation to proceed.
vMotion without shared storage, migrating virtual machines to a dierent 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.
