I was trying to convert windows 8 P2v on vmware ESXi 5 . Windows 8 converted successfully . but when I powered on it stuck windows start up screen and endless spinning circle .I was thinking P2V was not successful then i tried to install fresh windows 8 but there was same issue .
I Google it and got VMware article to patch the ESXi 5.0 to fix this bug. But there was easy solution .While creating virtual machine for windows 8 choose windows 7 64 bit operating system and install windows 8. Its resolved the issue for me .
