We use OpenNebula on Debian 8 to run KVM guests. Our latest upgrade of the host and guests broke badly. The host can not run guests with the latest kernels from Debian 8 and 9. If we downgrade the kernel on host or guest the problem is no longer present. To localize the root problem, I managed to launch a KVM guest on the command line using the lastest Debian live CD and the problem was the same. This is not a problem of OpenNebula. I need help to collect more information about what is going wrong on the guest and the host. Kind regards Jose M Calhariz
I have made videos of a guest live cd from Debian trying to boot and failing. qemu-system-x86_64 -enable-kvm -machine pc-i440fx-2.1,accel=kvm,usb=off -m 8096 -device cirrus-vga,id=video0 -device virtio-balloon-pci,id=balloon0,bus=pci.0,addr=0x5 -cpu host -msg timestamp=on -smp 4,sockets=4,cores=1,threads=1 -display vnc=:22 -cdrom ~cal/debian-9.5.0-amd64-xfce-CD-1.iso The most informative have 60MB. There is a recomended place to upload videos? If not, I can upload on my homepage at University. Kind regards Jose M Calhariz
This bug was filed against kernel version 3.16 and the chance that an upstream kernel developer will devote time to it is ~ 0%, so I'm closing this bug. If you can reproduce it with - the current version in unstable/testing - the latest kernel from backports please reopen the bug, see https://www.debian.org/Bugs/server-control for details. I'm sorry that a proper solution couldn't be found.
