I'm very sorry. > > Now, how do you start your guest exactly? Full cmdline pls. I used the following auto-test tool (its backend is ktest). https://github.com/satoru-takeuchi/elkdat This problem can be reproduced by the following command on Ubuntu 16.04. ``` $ sudo apt-get install git vagrant libvirt-bin libvirt-dev kernel-package qemu-kvm libssl-dev libncurses5-dev ... $ sudo usermod -aG libvirt <username> ``` Log out and back in here. ``` $ sudo sed -i'' "s/Specification.all = nil/Specification.reset/" /usr/lib/ruby/vendor_ruby/vagrant/bundler.rb # See https://github.com/vagrant-libvirt/vagrant-libvirt/issues/575 for more details about this patching $ vagrant plugin install vagrant-libvirt $ git clone https://github.com/satoru-takeuchi/elkdat.git ... $ cp -r /path/to/linux/source elkdat/linux $ cd elkdat $ ./init # start guest ... $ pushd linux ... $ git checkout v4.11-rc8 ... $ popd ... $ ./test boot # build and boot v4.11-rc8 ... # kernel panic happens here ``` The core of the starting guest process of above mentioned tools is as follows. 1. Add the vagrant box for the guest VM ``` $ vagrant box add elastic/ubuntu-16.04-x86_64 --provider libvirt ... ``` 2. Start the VM with the following Vagrantfile. ``` $ cd elkdat $ vagrant up ``` The summary of Vagrantfile is here. ``` Vagrant.configure("2") do |config| ... config.vm.define :ktest do |vm| vm.vm.box = "elastic/ubuntu-16.04-x86_64" vm.vm.synced_folder './', '/vagrant', type: 'rsync' vm.vm.provider :libvirt do |domain| domain.cpus = 2 end end ... end ``` Thanks, Satoru > > -- > Regards/Gruss, > Boris. > > Good mailing practices for 400: avoid top-posting and trim the reply.
