Hello there!. I wanted to share the good news that we've managed to migrate virtual Filr servers from SUSE Xen to SUSE Kvm.
For this I had to download the OVF version, convert the format vmdk -> qcow2 and then proceed with the usual migration procedure. I hope this is useful.
Note: if you need to deploy new Filr servers over KVM, you need to download the OVF, convert the vmdk to qcow2 and proceed normal following the normal importing the vm .
We love Filr. I'll look forward to hearing from you about when KVM could be officially listed in the supported virtualization platforms.
