ESXi host hangs on “usbarbitrator starting”

While upgrading our ESXi 4.1 hosts to ESXi 5.5 I found that the host would hang for almost a half hour on “usbarbitrator starting”. I did a little research and found this article http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=1023976. It said that you should disable the usbarbitrator service.

Start the ESX host and enter the following command at the Linux service console command line:
chkconfig usbarbitrator off

After I did that and rebooted the host, it was a much faster boot time and I was much happier.

Install of vCenter 5.5 hangs on Server 2012 R2

When I was installing vCenter 5.5 on a Server 2012 R2 vm in my home lab I had a problem with it hanging on “Installing Directory Services”. After trying to uninstall and reinstall a few times I discovered that Server 2012R2 does not include the OCSetup.exe file in %WinDir%\System32\ folder. I went to an existing instalation of Server 2008R2 and copied the file to my Server 2012R2 installation and reinstalled vCenter with no problem.
