SYMPTOMS

Assume you have a 4 nodes Hpyer-v cluster with more than 200 Virtual machines and 10 physical network adapters installed on the cluster node, each virtual machine is configured with 2 virtual network adapters; if you start 50 virtual machines on a single node at the same time or you failover 50 virtual machines to another node, you will find virtual machine configuration resources fail to be online after pending state. 

CAUSE

When a virtual machine configuration resource is online, mulitple WMI queries will be sent to query the network properties. The number of queries is decided by the number of virtual machines in the cluster and physical network adatpers on the cluster node. In the scenario described in Symtoms section, it takes more than 10 minutes for all virtual machine configuration resources online. However, the default resource deadlock timeout is 5 minutes, so you will see resource online failure due to timeout. 

RESOLUTION

Change the virtual machine configuration resource DeadlockTimeout and PendingTimeout value. The exact value depends on the cluster environment.
