With a clean ~/.virtualbox, I installed Debian Jessie Linux (8) on virtualbox-ose version 5.1.6 r110634.  Either during the install of Debian or afterward the virtualbox guest partially freezes.  If running a desktop environment in the Debian guest, the clock applet in the panel still keeps proper time, but little else seems to respond.  The following comes up in the guest's log:

  00:25:36.638384 AioMgr0-N: Request 0x000008261b36c0 failed with rc=VERR_TRY_AGAIN, migrating endpoint /home/will/VirtualBox VMs/Debian Testing/Debian Testing.vdi to failsafe manager.
  00:25:36.900555 AIOMgr: I/O manager 0x0000082d5933a0 encountered a critical error (rc=VERR_FILE_AIO_NO_REQUEST) during operation. Falling back to failsafe mode. Expect reduced performance
  00:25:36.913330 AIOMgr: Error happened in /wrkdirs/usr/ports/emulators/virtualbox-ose/work/VirtualBox-5.1.6/src/VBox/VMM/VMMR3/PDMAsyncCompletionFileNormal.cpp:(1669){int pdmacFileAioMgrNormal(RTTHREAD, void *)}
  00:25:36.913333 AIOMgr: Please contact the product vendor

When I try to close the guest with 'Power off machine' (either by closing the guest's window or by closing in the vbox manager), a small dialog comes up estimating the time it will take to close the machine.  The machine never closes and the estimated time in the small dialog grows to hours.  I must issue a 'killall -SIGKILL VirtualBox' in order to successfully close the guest.

No special options are being used for the installation and use of the Debian guest machine.  I will attach the config file, along with any relevant logs.

It appears on some of these freezes that the guest OS is still somewhat responsive, but there is a problem reading the disk.  Almost all commands that I enter into the guest's terminal return with "Input / Output error".  dmesg also returns the same error from the guest.
Comment 5 Will B 2016-12-23 21:30:45 UTC
Tests with Slackware 14.2 amd64 also yield the same issue.  So far, Windows XP guests don't have this issue.

This seems like AIO issue, these adjustments might help: bug #168298, comment #3

Thanks for the information Dmitri.

I have found that SATA virtual controllers need to have 'Use Host I/O Cache' enabled, then the freezes (mostly) go away.  

Virtual IDE controllers don't seem to need 'Use Host I/O Cache' enabled, however.

Is this still an issue? With e.g. 5.2.32_1

Unfortunately I'm unable to run FreeBSD on my current hardware to check right now.  Last recent experience didn't seem to have issues with this as I already knew to set the virtual controller to 'Use host cache'.

Hopefully one day FreeBSD will support my hardware and I can use it again. :-)

I can confirm that this is still an issue as of 2020-02-13.

hashbrown/home/jason-124957: uname -a
FreeBSD hashbrown 12.1-STABLE FreeBSD 12.1-STABLE r357056 JKERN12  amd64

hashbrown/home/jason-124958: pkg info virtualbox\*         

I'm using a Fedora-31 guest, but saw identical symptoms to OP.  Enabling "Use Host I/O Cache" on the virtual SATA controller fixed it for me.

Let me know of any other info I can provide or testing I can do.
