Migrate Virtualbox

[Mark Fletcher <mark27q1@gmail.com>]

Hello!

I have been reading from a couple of people on this list that Virtualbox 
is going away and will not be in stretch when it becomes the stable 
distro shortly.

I use Virtualbox for a couple of Windows machines to do the last task I 
cannot yet migrate to Debian (due to specialist software that is not made 
for Linux).

I am starting to contemplate migrating from Virtualbox to a different 
virtualisation solution that will be supported in Stretch.

My needs are fairly vanilla -- I have a 4-core-with-hyperthreading Intel 
Core i7 920 CPU, circa 2009, and 24GB or RAM in the host. I run 2 VMs, 
not all the time, which have 2 CPUs and 4GB of RAM each.

Access to physical optical drive, and virtual disks, is important. 
Shared folders with the host OS (which is currently Jessie and will be 
Stretch in the future) is important. 2D graphics is important, 3D less 
so. Ability to access physical USB equipment attached to the host would 
be nice but not a show-stopper. I have never got that working completely 
satisfactorily with my Virtualbox install, but suspect that is due more 
to insufficient time reading documentation than it is to limitations in 
the software (which should illustrate the importance of that element of 
things).

Minimal time futzing around to get the virtualisation solution working 
is important, as is not having to learn an entirely new paradigm to use 
the software. Stability of the result is also important.

And finally, a neat solution to migrate my Virtualbox machines to the 
new environment is very important -- I would infinitely prefer not to 
have to re-install from scratch into the new environment but would 
prefer to be able to migrate my Virtualbox disks to the new environment 
somehow, if anything supports that.

So my question is, is there an alternative solution in Debian that 
allows for that easy migration path -- any recommendations?

Thanks

Mark
