I had a very similar error after cloning a machine and trying restart either one of them. My problem seemed to be related to sharing the CD- ROM drive. I noticed any new machine I created would boot, but the original and its clone would not.
Here's what I did to fix my problem: Go into the hardware details by double clicking on the machine, clicking view details, click on IDE CDROM 1, and click disconnect. THIS machine now booted for me. The clone didn't boot until I did the same thing for it. I have little to no idea what the "disconnect" button does, but clicking it solved my problem. -- Unable to create a new VM when selecting PXE boot and kvm-pxe is not installed https://bugs.launchpad.net/bugs/478527 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
