VMware vCenter Server 4.0 Patch 1


VMware has released vCenter Server 4.0 Patch 1 to address an issue with VMware HA. From the VMware KB:

You experience these symptoms:

  • In vCenter 4.0, VMware HA might not failover virtual machines when a host failure occurs.
  • When the ESX host’s IP address in a VMware HA enabled cluster is configured with certain IP addresses, the node failure detection algorithm fails.
  • You are susceptible to this issue when all of your Service Console Port(s) or Management Network IP address(s) on your ESX host fall within the following range:
    3.x.x.x – 9.x.x.x
    26.x.x.x – 99.x.x.x

Note: You are not affected if one of Service Console Port(s) or Management Network IP address(s) on your ESX host falls outside of this range.
