We have developed [`kraft`](https://github.com/unikraft/kraftkit), an open-source tool which facilitates this across a number of different virtual machine monitors, [including QEMU](https://github.com/unikraft/kraftkit/tree/staging/machine/qemu). + +We are receiving increased reports of the following error from our users: + +``` +could not start and wait for QEMU process: qemu-system-x86_64: -qmp unix:/Users/__USERNAME__/.local/share/kraftkit/runtime/37a7691a-d402-4760-b493-692bb8d0460a/qemu_control.sock,server,nowait: UNIX socket path '/Users/__USERNAME__/.local/share/kraftkit/runtime/37a7691a-d402-4760-b493-692bb8d0460a/qemu_control.sock' is too long +``` + +We systematically build the relevant QEMU process command line and arguments with flags [via our Go SDK](https://github.com/unikraft/kraftkit/blob/staging/machine/qemu/v1alpha1.go#L180-L229) and include what has become an erroneously long UNIX path for the QAPI control socket which we use to manage instantiated VM instances. + +This issue tracks the increasing of maximum path length for the `-qmp` (and maybe other) flags which accept paths. +Steps to reproduce: +1. Install [`kraft`](https://github.com/unikraft/kraftkit), [Unikraft](https://unikraft.org)'s companion command-line client; +2. Update KraftKit's config file to include an arbitrarily long path for `runtime_dir` by editing `~/.config/kraftkit/config.yaml`; +3. Start a QEMU unikernel instance with `kraft run --arch x86_64 --plat qemu unikraft.org/helloworld:latest` +Additional information: + |
