I'm trying to run a pre configured Debian machine on my Mac Pro with Yosemite 10.10.4 on using VirtualBox 4.3.30. I import the appliance successfully but when trying to start it I run into the following error:
Failed to open a session for the virtual machine XXX.
Unsupported version 17 of data unit 'cpum' (instance #1, pass 0xffffffff) (VERR_SSM_UNSUPPORTED_DATA_UNIT_VERSION).
Result Code: NS_ERROR_FAILURE (0x80004005) Component: Console Interface: IConsole {8ab7c520-2442-4b66-8d74-4ff1e195d2b6}
It works fine with the 5.0.3 test version of VirtualBox, but I'd rather use the older version, and I really want to understand what's the problem. I scoped around the VirtualBox's Mac Users forum but couldn't find anything useful. Also, I had a friend of mine run it on her Mac air with Yosemite 10.10.2 on and it works fine, so I am guessing it is a problem of the last Yosemite release. But stil...
Any help would be appreciated :)
Thanks
