Fully Qualified Domain Name Length Limit is Changed in ESX Server 3.0.1 and VirtualCenter 2.0.1

Details

In the ESX Server 3.0 and VirtualCenter 2.0 release, you were limited to 29 characters for the Fully Qualified Domain Name(FQDN). If the FQDN was longer, the VMware High Availability(HA) configuration task failed or your virtual machines did not failover. See http://kb.vmware.com/kb/2259 for more details.
 
The ESX Server 3.0.1 and VirtualCenter 2.0.1 release relaxes this limit, raising the maximum length of FQDN to 255 characters.
 

Solution

With the ESX Server 3.0.1 and VirtualCenter 2.0.1 release and later releases, you will not encounter problems resulting from FQDN length as long as you observe these guidelines:
  • Make sure the FQDN is 255 characters or less.
  • Make sure the hostname portion of the FQDN is 31 characters or less.
