Attempting to run VMs located on an external USB 3.0 HD crashes OS X.

I'm running Fusion 5.0.3 on Mountain Lion 10.8.2 on my RMBP. Running VMs from the local SSD (256GB) works, but when I attempt to run VMs (either newly created or ones I copy after OS install) from an external NTFS-formatted USB 3.0 hard drive, OS X crashes and reboots. I enabled writing to NTFS by following these instructions. I'm able to read and write to the external hard drive with no issues, in fact it's significantly faster than other USB 2.0 external hard drives I own. Is anybody else having this issue and know how to fix?

Below is the "problem" that was reported:

Two things:

1) Upgrade to 10.8.3, it had a HUGE number of bugfixes.

2) The issue is highly likely to be the NTFS format on the external drive.  OSX doesn't support it, and third-party drives are problematic at best.  Reformat the drive as either FAT32 or HPFS+ (Mac format).  I'd avoid exFAT at the moment too, as it's more prone to corruption.  If you use FAT32, your VM's will need to be split into 2GB chunks.

dlhotka, thanks for the response. I upgraded to 10.8.3 and still get the same error. It does look like it's one of the components I installed to get RW working with NTFS (fuse4x). I guess that I'll use the external drive for VM storage (and only run from the internal HD) for now as I'd prefer to keep the drive formatted NTFS for compatibility.

FAT32 is the most compatible file system out there :-).

But yeah, if you're on 10.8.3, then it definitely looks like it's the NTFS issue.  You may experience issues going through the shared folders function too (since that'll trigger the OSX drivers).  If you can, just mount it directly in the VM.

As a general rule I normally do not write to NTFS Volumes from OS X on a daily basis however I do on occasion and at times write some individual files that are large, 10 to 50 GB and have yet to have any issues.  I normally do not run VM's from the NTFS Volume under OS X although today I played around for a while doing lots of disk activity seeing if it would be problematic and it wasn't.

Now I did not use the same methods you did to enable write support for NTFS under OS X and though I'd share with you what I'm using.  On my newest MacBook Pro I installed just two things, OSXFuse 2.5.5  (2.5.6 has been release since I install 2.5.5 however I've not updated it yet) and the commercial version of Tuxera NTFS for Mac 2012.3.6.

As a general rule I normally keep Tuxera NTFS for Mac disabled and enable it on the fly when I need to write to an NTFS Volume as it is something I do more as the exception not necessarily the rule. However since over the last year I've written a couple terabytes of data, especially very large files to NTFS Volumes from OS X and making sure MD5/SHA1/SHA256 checksums match and have yet to have issues and I consider it safer then using ExtFAT for my use.

This is a defect or limitation in fuse4x.  Its complaint, "mmap being attempted with no region accessibility", is entirely bogus, since it is specifically permitted to mmap a region with no accessibility.  The documentation for mmap(2) even reveals that there is a defined constant, PROT_NONE, that the caller of mmap should use to request that the region be mapped with no accessibility.  That's what we are doing when this failure occurs in fuse4x.

I would expect that this failure will occur whenever an attempt is made to power on a VM whose .vmem (the file which backs the virtual machine's RAM) is located on a filesystem provided via a version of fuse4x with this problem.

You may be able to work around the problem by using virtual machine config options to move the .vmem file to another volume which does not need fuse4x.  (I don't immediately recall which options... others here might, or I can try to dig them up...)

To really fix this issue, you'll have to find a filesystem driver without this limitation, whether it's a newer version of fuse4x or another filesystem driver altogether.
