2323* **QEMU and UEFI firmware**: `qemu-system-x86`, `ovmf`, and `virtiofsd` on x86\_64, or `qemu-system-arm`, `qemu-efi-aarch64`, and `virtiofsd` on arm64. `apt install claude-desktop` installs them by default as recommended packages. If you installed with `--no-install-recommends`, or your system is a minimal image that skips recommended packages, the Cowork tab reports "Cowork requires QEMU" and shows the `apt install` command to run. Ubuntu 22.04 has no `virtiofsd` package; the app uses a bundled copy there.
2424* **Access to `/dev/kvm`**: add your user to the `kvm` group with `sudo usermod -aG kvm $USER`, then log out and back in. Some desktop environments grant the logged-in user access to `/dev/kvm` without the group, but Cowork also needs `/dev/vhost-vsock`, which only `kvm` group members can open. Join the group even if `/dev/kvm` already works for you.

26The app checks these requirements once at launch: restart it after installing packages, and log out and back in after joining the group. If your kernel has no module directory under `/lib/modules`, which is common on ChromeOS and in container-based Linux environments, the Cowork tab reports that the kernel doesn't include the virtualization support Cowork needs and that it can't be added manually.
