Re: [Kimchi-devel] [PATCH V2 2/7] (WIP) Storagepool SCSI/FC: Function to check libvirt version

As Kimchi supports a large range of Linux distributions and libvirt versions may differ. Libvirt functionalities may not be available, what requires different implementations of kimchi code. This patch implements a function to help identify libvirt version.
