Newly Configured Virtual Network Fails to Establish a Connection With the Virtual Switch

Bug ID 6765355: Under rare conditions, when a new virtual network (vnet) is added to a logical domain, it fails to establish a connection with the virtual switch. This results in loss of network connectivity to and from the logical domain. If you encounter this error, you can see that the /dev/vnetN symbolic link for the virtual network instance is missing. If present, and not in error, the link points to a corresponding /devices entry as follows:

/dev/vnetN -> ../devices/virtual-devices@100/channel-devices@200/network@N:vnetN

Workaround: Do one of the following:

• Perform a reconfiguration boot of the logical domain, whenever a vnet is added to the logical domain.

• If the logical domain is already booted, run the devfsadm(1M) command before plumbing the vnet.
