The 'error' was that the virtual server was extremely slow. Taking over 200 seconds to boot, when the physical server takes only about 14 seconds. I eventually found the problem. the module kvm_intel wasn't being loaded by the physical server, and so the virtualization was extremely inefficient. It turns out it was a bios update that switched the virtualization off in the bios. Once that was changed back, all the problems went away.
The warning was the only thing I could find that might point to what could be wrong. Until I checked and found that there was no file: /dev/kvm, and modprobe kvm_intel gave an error. Then a tail of dmesg showed that the bios setting was wrong. -- [intrepid] kernel bug https://bugs.launchpad.net/bugs/337551 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
