I had the same problem today and eventually resolved it by following the recommended solution in this thread.
To quote CCIE17603....
The Fix: all you have to do is ssh into your host and run this command from the cli:
# vmkload_mod multiextent
Unfortunately after a ESXi host reboot the multiextent module unloads and you have to perform this again to get your Sims to boot. If anyone can find a way to make this persistent with a switch or write a script that makes it load upon host reboot. I'm sure everyone would be very thankful.
I'm running 8.3 RC1 on ESXi 5.5 U2. As soon as I'd done the vmkload_mod multiextent I was back in business.

To fix the problem permanantely, do this. Use vmkfstools to basically clone off the VDMK into a format that doesn't require the multiextent module loaded.

If you do a lot of work with simulators, its easier to just persistently enable multiextent:
add the following:
localcli system module load -m multiextent
to this file:

Another Way to have some Sim running with ESX 5,5 ....
Put the sim files on a disk accesible by the vcenter, and with the Vmware Converter do a convertion to the vSphere cluster with the files in sources ...
And dollow the documentations of SIM installation

And another way:
Delete the 250gb disk on IDE1:1, and replace it with a new one. Thin provisioned is ok.
As long as its done before the first boot, the sim will partition it during init and mount it on /sim
