Bug 215526: emulators/virtualbox-ose: Machine freeze with Linux guest
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=215526

VBoxSVC.log.1

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.
