Hi,
I have Ubuntu 16.04 installed in a Dell Precision M6500. The guest is Centos 7. Until yesterday everything was working just fine. At certain point the guest crashed, so I attempted to restart. What I was seeing is that the three superimposed progress bars were moving very slowly, when finally they got to the end the system got stuck there showing the bars as well as a black screen. I attempted to boot from different kernel versions in the grub menu, but the result was the same. I also attempted to boot into single user mode by adding the word "single" at the end of the grub boot statement but again, it didn't make any difference. I even re-installed virtualbox from the synaptic menu, but nothing changed.
I would appreciate very much any help.
Daniel

Post the guests log file ( as an attachment ). Right click on the guest in the Main Manager then click show log. Save and post as an attachment. Compress if it is too large to post.

Re: Guest machine does not start
I understand. One general question: how do I mount the vdi image so I can poke inside the guest?
Thanks
Thanks

Re: Guest machine does not start
Easiest way if the OS is not totally trashed is to attach it as a second drive to a working guest, and mount it as such.
Of course a backup of the guest before it crashed would be preferred.

Re: Guest machine does not start
can this working guest be a windoze?
or what method would be available to mount it under the host?

Re: Guest machine does not start
Maybe if your "windoze" supports the format of the guest.can this working guest be a windoze?
There are some 3rd party programs that say they will do this but I have never used them ( you would need to search for them ). I find it easier to mount as a second drive. Even a livecd will do the trick.or what method would be available to mount it under the host?

Re: Guest machine does not start
You were right - it was an issue with selinux, so booting from the install media allowed me to re-install the selinux-policy-targeted and voila! The system booted.
Thank you very much for your time and promptness.
