Summary: cannot create a Windows 7 VM with Virtualbox 5.1.26 (FreeBSD 11.[01])
A VM can be created with VirtualBox 4.3.38 (FreeBSD 10.3)

I upgraded to FreeBSD 11.1 and installed VirtualBox 5.1.26 using PKG on 2 Aug
2017. The Windows 7 VMs I had created under FreeBSD 10.3, Virtualbox 4.3.38 OSE
r106717 were imported and ran without problems.  However,  when I tried to
create a new VM on FreeBSD 11.1/11.0 using VirtualBox 5.1.26, both from the
PORTs repository AND when compiled from source,  I got the same set of

When installing Windows 7 you start by creating a virtual machine flagged as
Win 7 64amd.  You boot the virtual machine and provide it an ISO image of the
Win 7 64 bit Install CD.  The VM then boots from the CD,  goes through a
prelimiary setup phase,  and then starts to copy and unpack files from the ISO
image.  During this process it displays a progress bar showing the amount of
work done.

The unpacking operation appears to fail randomly - 10%, 12%, 20%, 26%, 54%.
If you google the failure message,  then problem (according to MS) is that you
have either a bad DVD, or memory and to take corrective actions.

The ISO image checksum matches the published MD5 checksum.  I have tried this
on two different systems with the same result.  I am attaching screenshots
showing the output of the install and the Vbox.log file.

In the Vbox.log file there appears to be a hint of the cause of the failure:
