Public bug reported: Cloud Hypervisor is an open-source Virtual Machine Monitor (VMM) that runs on top of KVM. It is built on top of the rust-vmm project and focuses on running modern cloud workloads on a narrow set of hardware architectures and platforms (x86_64 and aarch64). Cloud and container workloads are its primary targets, emphasising simplicity, security, and minimal attack surface over legacy device emulation.
URL: https://github.com/cloud-hypervisor/cloud-hypervisor License: Apache-2.0 OR BSD-3-Clause (upstream), vendored crates under various DFSG-free licenses PPA: https://launchpad.net/~gjolly/+archive/ubuntu/cloud-hypervisor Notes: This package is submitted directly to Ubuntu rather than going through Debian because cloud-hypervisor is a Rust application with ~293 transitive crate dependencies (per Cargo.lock). Packaging it the Debian way would require individually packaging each crate via debcargo, which is impractical given the volume and the fact that many of these crates (rust-vmm ecosystem: vm-memory, vhost, kvm-ioctls, etc.) have no other consumers in Debian. For this reason, all Rust dependencies are vendored into a separate orig tarball. The package builds for amd64, arm64, and riscv64. Two patches on top of upstream 52.0 were needed for riscv64: one fixes missing imports/cfg coverage for the RISC-V UEFI loader and migration timing code (upstream commit 1e18716fbdc0), the other permits readlinkat and unlinkat in the riscv64 seccomp filters so the hypervisor is not killed by its own seccomp policy at runtime (upstream commit 7d1321515cac). Both are already merged upstream and can be dropped once a newer upstream release is available. It builds and installs cleanly from the PPA linked above. Lintian (lintian -iIE --pedantic --profile ubuntu) reports no errors or warnings, only minor informational tags. The package includes autopkgtests that verify a kernel can be booted under cloud-hypervisor. Upstream maintains OBS-based packaging for .deb and .rpm at: https://github.com/cloud-hypervisor/obs-packaging/tree/main/cloud-hypervisor/deb Two differences with the upstream OBS packaging worth noting: - The OBS package sets cap_net_admin+ep on the cloud-hypervisor binary so unprivileged users in the kvm group can launch VMs with networking. This Ubuntu package does not set that capability for now, but I am open to adding it if reviewers consider it acceptable. - The OBS package also ships vhost_user_block and vhost_user_net helper binaries. This Ubuntu package omits them as they are not strictly needed for core VMM operation, but I am open to reconsidering if there is demand for them. ** Affects: ubuntu Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2158959 Title: [needs-packaging] cloud-hypervisor To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/2158959/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
