vCenter 5.5 - Grub error hot-cloning Ubuntu 12.04

[JDDD]

Hi All--

I am having quite a time hot-cloning an Ubuntu 12.04 VM from one vHost to another vHost.

Both vHosts are running ESXi 5.0.0 build 623860.  I am using the VMWare vCenter Converter Standalone Client 5.5 build-1362012.  The VM in question is running Ubuntu 12.04.2.  The VM is using LVM, which I have read may have an impact.

When running the converter, I get to 97-99% done, then get the error as follows:

an error occured during the conversion: grubinstaller::installgrub: /usr/lib/vmware-converter/installgrub.sh failed with return code: 126, and message: chroot: can't execute '/vmware-updategrub.sh': exec format error

error running vmware-updategrub.sh through chroot into /mnt/p2v-src-root

/usr/lib/vmware-converter/installgrub.sh: line 143: /mnt/p2v-src-root: is a directory

I have looked all over trying to find anyone that has received that exact error message, but cannot.  I have tried the steps outlined here but have been unsuccessful.

If anyone has any insight into why this error is occuring, how to fix it, etc, it would be greatly appreciated!!

Well... I finally went ahead and rebuilt the server on which vCenter Converter Standalone was running.  I then did a fresh install of the converter and reran the task and all went well.  I think it might have been an issue of the wrong version *.iso being mounted as the converter helper.  I had to keep manually mounting the iso to the new VM and boot before it would actually go through, and occasionally i would get prompted for "converter login" credentials.

I will chalk this up to a bad upgrade/install/accumulated junk on the vCenter system.
