<div dir="ltr">I see. Thanks for the info! now I know how I can work around this. The BSD system was pfsense, so I can just install new and reload the configuration, as for atomic, I don't have a large number of them so I will just install new and docker load the containers in. </div><div class="gmail_extra"> <div class="gmail_quote">On Fri, Apr 7, 2017 at 1:12 AM, Pino Toscano <<a href="mailto:ptoscano@redhat.com" target="_blank">ptoscano@redhat.com</a>> wrote: <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">Hi, On Friday, 7 April 2017 03:57:30 CEST solarflow99 wrote: > I have a Fedora 24 system I can already get this working for most OVA > files, just the BSD and atomic ones weren't recognized. BSD systems are not currently supported by virt-v2v, they need an ad-hoc conversion module. Inspection of Atomic systems currently does not work, see also <a href="https://bugzilla.redhat.com/show_bug.cgi?id=1102241" rel="noreferrer" target="_blank">https://bugzilla.redhat.com/show_bug.cgi?id=1102241</a> > Assuming my > version of virt-v2v is just old, I installed rawhide on a different system > and tried with virt-v2v-1.37.8-1.fc27.x86_64 and now its having another > problem. Is there a known version of virt-v2v I should be using?

On Fedora, libguestfs uses libvirt by default to spawn an appliance, and libvirt uses by default a non-priviledged user when running as root. We have a (ugly IMHO) workaround for some of the cases, as you can see from a snippet of the output: | virt-v2v: warning: making OVA directory public readable to work around | libvirt bug <a href="https://bugzilla.redhat.com/1045069" rel="noreferrer" target="_blank">https://bugzilla.redhat.com/1045069</a> but it doesn't always work. The ways to overcome this problem are 1) run virt-v2v as non-root 2) temporarly export LIBGUESTFS_BACKEND=direct for that virt-v2v execution -- Pino Toscano</blockquote></div> </div>
