Add libvirt/KVM VM scripts for Linux x86_64 testing#5
Merged
Conversation
Add setup and test scripts for running netdevsim DKMS smoke tests and ptp-operator e2e tests inside libvirt/KVM VMs on Linux x86_64 hosts. Scripts: - setup-libvirt-ubuntu.sh: create VM, install DKMS, add SSH config - test-libvirt-ubuntu.sh: full lifecycle including ptp-operator tests Update README with libvirt setup docs and test instructions: ./run-on-vm.sh --dkms --mode oc,bc,dualnicbc,dualnicbcha,dualfollower <VM_IP>
Use LIBVIRT_DEFAULT_URI=qemu:///system so virsh/virt-install connect to the system daemon via polkit instead of requiring root. Only sudo is used for starting libvirtd if it is not already running. The script now checks for libvirt and kvm group membership and gives actionable errors.
- Store qcow2 disk and cloud-init ISO in ~/.local/share/netdevsim-dkms/ so the VM survives script exit - Use LIBVIRT_DEFAULT_URI=qemu:///system with polkit instead of root - Detect QEMU user (libvirt-qemu/qemu) and check ACL permissions - No sudo calls; script exits with actionable fix commands instead - Update README with group membership and ACL setup instructions

Worked great for me under Fedora-43, thank you! |
