VM SDA drive cache, modprobe FAILED, reboot FAILED

[-TJ-]

When booting a new Management Server VM on R80.20.   (built from ISO  R80.20 T117)   -Thick provision lazy 

The maintenance mode prompt and that white bar that moves from left to write doesn't display.  Instead, I see:

sd 0.0.0.0: [sda] Assuming drive cache: write through

--30 second pause---

modprobe startup FAILED

When I issue a reboot from GAIA, the standard "the system is going down for reboot NOW!" message, then

--short pause--

FAILED

please stand by while rebooting the system...

I recently lost my primary management server file system was corrupted, unable to retrieve local snapshot and VM restore failed.  [rough day] I had to promote secondary.  I build a new primary which has no issues.   Now I'm building a new standby.  That info isn't relative to the issue above.  I'm only sharing that to convey how wary I am to discount any error messages.

sk126473 says to reinstall GAIA.    Which I have now twice.  but message continues.  

ISO image MD5 is matchy matchy too.     Anybody have advice?  Phoneboy

Nevermind. Fixed it.
Needed to use vmware compatibility mode.

Can you give further information on how to set this option? I have a similar situation.
