[libvirt] virt-install ERROR Host does not support any virtualization options

Hello, I face this problem and I am willing to provide a patch in order to have a more informative message. This, of course with our help. I am not quite certain. First of all: What is the problem? On a fresh Install (ArchLinux for me), if ever forget to install Qemu and launch "virt-install" with "--type kvm", I get the message: "Host does not support any virtualization options" According to me, this message should be improved: if Qemu is not found, this should be "Did not find Qemu, please install it". As I searched, the message is generated by this piece of code: https://github.com/virt-manager/virt-manager/blob/c92aade081687b19f5a60cd... As I write now, I cant find the pice of code actually calling the "quemu" binary. I think I should add a try/catch block there and Raise the right Exception. Would someone help me a bit? Thank you.
