I have an Ubuntu 20.04 Virtualbox host.
I built an Windows guest VM successfully so that another user runs this. I have made that user account the owner of that particular directory. When I run the VM, it displays this error attached.
Can anyone work out why the attached is displayed?
Windows guest not starting up

Re: Windows guest not starting up
According tou your information, this was working:
Curiously a web-search on
"Linux Hosts" NS_ERROR_FAILURE "exit code 1" site:forums.virtualbox.org
shows one of the results here viewtopic.php?f=7&t=96377#p469342 which says that permissions changes can cause this problem.
then you did this:eastway wrote:I built an Windows guest VM successfully so that another user runs this.
then the error appeared. So if you undo the permissions change, does the VM start running again?eastway wrote:I have made that user account the owner of that particular directory.

I changed the permissions back and still not working.

Didn't actually check, a colleague of mine noticed change of owner and group in /etc, /opt and /usr which caused the issue.
