After upgrading to 3.1.6 it worked again!

<div>
<div class="content wysiwyg-content">
I use VB for classcomputers and now I am going crazy?<br />
<br />
Until recently (before upgrading VB) after a class I used a commandline:<br />
VBoxManage snapshot &quot;IMAGE&quot; discardcurrent -all.<br />
<br />
Then everything was back to how it was before the class. Now it does not seem to work. I do NOT want to merge the snapshot I want to return to no snapshot without merging. I have Googled my ass of for this. Why is it so difficult??<br />
<br />
I am in a hurry so therefore I give this one 500!

VirtualBox discard all snapshots

Programs written for the Apple operating systems are distinguished from software created for other operating systems in that it must be approved by Apple for use on its devices, whether it is from Apple (Final Cut, iWork, Keynote, Logic Pro and GarageBand are popular titles), or is a third party application from Parallels, Nuance, Microsoft and Amazon, among many others.

Virtualization is the act of creating a virtual (rather than actual) version of something, including (but not limited to) a virtual computer hardware platform, operating system (OS), storage device, or computer network resources. Virtualization is usually the creation of a system that executes separate from the underlying hardware resources, or the creation of an entire desktop for systems located elsewhere, similar to thin clients.

Virtualization

VMware, a software company founded in 1998,  was one of the first commercially successful companies to offer x86 virtualization. The storage company EMC purchased VMware in 1994. Dell Technologies acquired EMC in 2016. VMware’s parent company is now Dell Technologies.

VMware has many software products that run on desktops, Microsoft Windows, Linux, and macOS, which allows the virtualizing of the x86 architecture.  Its enterprise software hypervisor for servers, VMware vSphere Hypervisor (ESXi), is a bare-metal hypervisor that runs directly on the server hardware and does not require an additional underlying operating system.
