In the topology of the distributed switch, check the VLAN IDs of the physical NICs that are assigned
to the active uplinks on the distributed port group. On all hosts, assign physical NICs that are from the
same VLAN to an active uplink on the distributed port group.
n
To verify that there is no problem at the physical layer, migrate the virtual machines to the same host
and check the communication between them. Verify that inbound and outbound ICMP traffic is
enabled in the guest OS. By default ICMP traffic is disabled in Windows Server 2008 and Windows
Server 2012.
Attempt to Power On a Migrated vApp Fails Because the
Associated Protocol Profile Is Missing
You cannot power on a vApp or virtual machine that you transferred to a data center or a vCenter Server
system because a network protocol profile is missing.
Problem
After you cold migrate a vApp or a virtual machine to another data center or vCenter Server system, an
attempt to power it on fails. An error message states that a property cannot be initialized or allocated
because the network of the vApp or virtual machine does not have an associated network protocol profile.
Cannot initialize property 'property'. Network 'port group' has no associated network protocol profile.
Cannot allocate IP address for property 'property'. Network 'port group' has no associated network
protocol profile.
Cause
By using the OVF environment, the vApp or virtual machine retrieves network settings from a network
protocol profile that is associated with the port group of the vApp or virtual machine.
vCenter Server creates such a network protocol profile for you when you install the OVF of a vApp and
associates the profile with the port group that you specify during the installation.
The mapping between the protocol profile and port group is valid only in the scope of a data center. When
you move the vApp, the protocol profile is not transferred to the target data center because of the
following reasons:
n
The network settings of the protocol profile might not be valid in the network environment of the target
data center.
n
A port group that has the same name and is associated with another protocol profile might already
exist in the target data center, and vApps and virtual machines might be connected to this group.
Replacing the protocol profiles for the port group might affect the connectivity of these vApp and
virtual machines.
