Description

Currently ACS waits for 15 seconds (hard coded) for hot-plugged NIC in VR to get detected by guest OS. The time taken to detect hot plugged NIC in guest OS depends on type of NIC adapter like (E1000, VMXNET3, E1000e etc.) and guest OS itself. In uncommon scenarios the NIC detection may take longer time than 15 seconds, in such cases NIC hotplug would be treated as failure which results in VPC tier configuration failure. Making the wait timeout for NIC adapter hotplug as configurable will be helpful for admins in such scenarios.
Also in future if VMware introduces new NIC adapter types which may take time to get detected by guest OS, it is good to have flexibility of configuring the wait timeout.
