Virtual Machine Cloning Is Failed At 33%

English 1 Minute

I got two exactly same hardware, installed same ESXi version. Somehow cloning from  other ESXi to one server was working, but another one always failed at 33%.

It only impacts to existing VM cloning but not impact to new created virtual  machines. I spent lot time on the troubleshooting. We replaced cables, switch ports, reinstalled ESXi.

There was no  abnormal logs except following:

VMware support eventually provided me following KB to workaround the problem. Looks like it’s a bug on ESXi 5.5 2068190.
