Hi Dexter, Joe, I read Joe's question as "is there bhyve on ppc64". Unless there's a private fork, today bhyve exists on amd64, arm64, risvc only - see the subdirs https://cgit.freebsd.org/src/tree/usr.sbin/bhyve . > Power, RISC-V, and ARM64 virtualization came up on Thursday with > enthusiasm about various Power platforms: > > https://www.youtube.com/watch?v=VQwnlNL4cOI > > Does anyone know why there are no PPC VM-IMAGES? > > Dexter In answer to your question, why no PPC VM IMAGES, it needs 2 things: - patches to /usr/src/release/tools/ to build the appropriate images from sources (i.e. locally for developers) - an indication of enough demand to add the plumbing so that these images are built as part of releng tooling like we do regularly for stable/current/releases etc (i.e. on downloads.freebsd.org ) The patches themselves aren't typically complicated, you just need to get familiar with the Makefiles that are used for other platforms in here https://cgit.freebsd.org/src/tree/release/ . The latter question is up for debate, I expect the venn diagram of people using ppc, and people who will use VM images *but can't build them from sources* is not big enough to justify building & storing the images every week on all the mirrors, but making it available for people to build them from sources seems reasonable, if somebody wants to work on it. It *may* also require proper qemu ppc64 support, I don't know if that's already possible, to cross-build packages on amd64 builders, for ppc64 architecture. A+ Dave
