First popup reads:
It appears over the top of a popup which simply reads:VirtualBox - Error
Start LM-MATE64 errors:
You must specify a machine to start, using the command line.
Usage: VirtualBoxVM --startvm <name|UUID>
Starts the VirtualBox virtual machine with the given name or unique identifier (UUID).
When I click OK on the error window, both of the above popup windows close and a second error popup window opens which reads:Starting VM
Creating process for virtual machine "LM-MATE64"
I am starting the VMs from VB Manager by selecting the VM and clicking the Start button, as I have always done. Oddly, on Tuesday, Sept. 21, I was able to start my primary VM from the saved state in which I had left it the previous Friday, was able to use it for a short time, and I intentionally shut it down (i.e., not saved state). Since then I always get these errors no matter what I've done from restarting the host to restarting VirtualBox. I think my IT dept. changed something on the host the week before it stopped working, but I can't tell what. And I am so far getting no response from the ticket I raised with them to investigate. I am hoping to get some insight into what might be causing my problem from the forum so I can take it up with them when I do finally get a response. I can provide the VBoxHardening.log file if it would be of use, but it ends with this, which doesn't tell me anything intelligible:VirtualBox - Error
