I'm off topic here (my problem happened on gentoo, not Arch) but in case it might be useful to someone: I upgraded from vbox-4.3.30 along with the matching extensions and fired up my gentoo vbox guest machine (this was an existing guest, not a newly created one) did the usual update process and then saved a new snapshot. All of that seemed to work normally until I tried to restart the guest machine and got lots of error messages from vbox that it couldn't load (or parse) some of the files defining the guest, i.e. on my host machine, these files: ls -l ~/VBoxVMs/gentoo/ total 21162196 drwx------ 2 wa1ter wa1ter 4096 Aug 2 07:02 Logs drwx------ 2 wa1ter wa1ter 4096 Aug 2 09:20 Snapshots -rw------- 1 wa1ter wa1ter 54745 Aug 2 09:20 gentoo.vbox -rw------- 1 wa1ter wa1ter 54745 Aug 2 09:20 gentoo.vbox-prev -rw------- 1 wa1ter wa1ter 21669961728 Jul 29 19:23 gentoo.vdi I stopped at that point and reverted to vbox-4.3.30 because I just wanted to avoid any further damage. When I used vbox-4.3.30 to restart the gentoo guest machine, it wouldn't run. I don't recall now what error messages appeared. I saved gentoo.vdi but deleted the rest of the gentoo guest machine and recreated it using gentoo.vdi as the starting point. Everything returned to normal after that. I just noticed that gentoo offers two different versions of vbox-5.0.0: the one I compiled myself using the normal gentoo infrastructure, and a binary package (virtualbox-bin) which is downloaded directly from the virtualbox.org website. I'm wondering now if the package I compiled was faulty somehow. Based on all the good reviews in this thread (thanks guys) it seems likely.
