## Summary Fixes Defend Workflows Cypress CI failures caused by VirtualBox kernel module not being loaded on CI agents. The CI image ships with VirtualBox 7.0.x, but recent GCP kernel updates (`6.17.0-1008-gcp`) break module compilation for that version. ### Changes **New: `ensure_virtualbox.sh`** — shared pre-flight script sourced by all Defend Workflows CI scripts. It: 1. Checks if `VBoxManage --version` reports a healthy state (not just exit code — parses output for "kernel module is not loaded" warning) 2. Attempts to load existing kernel modules (`modprobe vboxdrv`, `/sbin/vboxconfig`) 3. If module build fails (kernel too new for VirtualBox 7.0.x), upgrades to **VirtualBox 7.1** from Oracle's repo which supports newer kernels 4. Exports `VAGRANT_DEFAULT_PROVIDER=virtualbox` to skip Vagrant's provider auto-discovery 5. Prints full diagnostics on failure (packages, kernel version, DKMS status) **Updated: `vm_services.ts`** - `VAGRANT_DEFAULT_PROVIDER=virtualbox` set in vagrant env on CI (local dev keeps VMware auto-discovery) - Pre-flight disk space check **Updated: `Vagrantfile`** - Installs `unzip` via `apt-get` for provisioning ### Files changed - `.buildkite/scripts/steps/functional/ensure_virtualbox.sh` (new) - `.buildkite/scripts/steps/functional/defend_workflows*.sh` (4 files — source ensure_virtualbox.sh) - `x-pack/.../endpoint/common/vm_services.ts` - `x-pack/.../endpoint/common/vagrant/Vagrantfile` --------- Co-authored-by: kibanamachine <42973632+kibanamachine@users.noreply.github.com> (cherry picked from commit 11333fb)
