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/1555705/

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?

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?

BR,

Zhenyu

Hi,

Any other comments for this topic?

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.

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.
