Re: [ovirt-users] DevConf.CZ 2016 - my experience

Hello, "Would be cool to support ARM based hosts running virtual machines!" I would also be very interested in that. I recently visited the Centos Dojo in Brussels and also came away with the idea that the ARM road is very long. This seems like an opportunity to ask: this is not possible on any board right now?

I was thinking: http://www.lemaker.org/product-hikey-specification.html Hummingboard Edge https://www.solid-run.com/freescale-imx6-family/hummingboard/hummingboard...
