Hi oVirt,
We are currently trying to make oVirt work on ARM64 platform, since I'm quite new to oVirt community, I'm wondering what is the current status about ARM64 support in the oVirt upstream, as I saw the oVirt Wikipedia page mentioned there is an ongoing efforts to support ARM platform. We have a small team here and we are willing to also help to make this work.
Hi Zhenyu, I think this is a great idea, both supporting more hardware, and enlarging the oVirt community. Regarding hardware support we depend mostly on libvirt and qemu, and I don't know that is the status. Adding relevant lists and people. I don't know about any effort on oVirt side, but last week I added arm builds for ovirt-imageio and it works: https://copr.fedorainfracloud.org/coprs/nsoffer/ovirt-imageio-preview/build/... We have many dependendencies, but oVirt itself is mostly python and java, with tiny bits in C or using ctypes, so it should not be too hard. I think the first thing is getting some hardware for testing. Do you have such hardware, or have some contacts that can help to get hardware contribution for this? Nir
Hi Nir, Thanks alot for the quick response and information, actually I also worked a little bit on libvirt and other from our team has experiences in qemu, those projects works OK on ARM platform, it is just the capability might be less when comparing to other platforms, for example, myself just added the getHost() capability for ARM64 in libvirt and now planning to work on compareCPU() API, after that we will have better migration workflow on ARM platform. For resources, actually, yes, I think we can provide those for oVirt community, could you tell me more details about what kind of resources are more suitable, our current resources are mostly VMs from public cloud, will that be OK?

libguestfs, nbdkit and virt-v2v have also worked (upstream) for years out of the box on aarch64, so there should be no problem there. If you're interested in RHV (ie. oVirt downstream on RHEL) then note we don't build virt-v2v for RHEL on aarch64. Virt-v2v is not very useful on aarch64 since there is not (yet) any public VMware version for aarch64, although VMware do have an internal build and rumoured plans for ESXi on aarch64.

Supports shell scripting, bindings from many languages. http://libguestfs.org

libvirt and qemu both support aarch64 guests and hosts for years now, as do various KVM mgmt apps, so I think its largely just a matter of the oVirt code that needs porting and updating to deal with any aarch64 specific aspects.
