      You also need to have your user added to the libvirt group on the KVM host.

        Of course I can just create a directory on the server and then download ISO's directly into it. . .

        But I'd rather not. Hrm. . it works, but seems weird.

        Well I do not download from the KVM server, I do always have a "iso_store" folder on my KVM server that I have ISO files in.

        Sometimes it is a remote share mounted, most of the time it is local to the /root partition.

          Yea so what I did is I SSH'd to the server, and ran sudo mkdir /media/iso and then ran wget <url.iso> and it works. But it seems like the wrong way to have to do this. . .

            I will generally mkdir /iso_store and then from my desktop scp the .iso files over.

              It's the way I've seen folks do it with VMware, or XenServer, or Hyper-V... Why should KVM be any different?

                @dafyre I can't share out a local dvd drive to server (that seems weird). Maybe I'm just trying to set it up incorrectly. But my goal would be to not have to store ISO's on the hypervisor at all.

                Instead share out a local directory and have the server browse that to mount any ISO's as required.

                  then make the mount on the KVM server to the share, what is the issue here?

                    Key based Auth will fix the problem of asking you for your password 500 times.

                    For the ISOs, I usually make a separate folder and add it as a Storage Repo... Then just SCP the ISO's into the folder and you're good to go.

                    Any recommendations on how to setup the keys?

                    As for the "creating a separate folder", do you mean in here? I guess the question is, why can't I either just share the CD Rom with the server?

                    That's what ssh-copy-id was made for. Makes copying your key to a remote host quick and easy.

                      OK so I have my rsa keys shared and distributed, now I'm trying to add the connection in Virt-Manager and it doesn't seem to want to take the combination.

                      I can still connect using root or the user account on the server with the password though.

                          did you put in a password for the key encryption?

                          As Travis said, use ssh-copy-id user@remotehost

                            Nope, no password when generating the key. Just blank.

                            The key is copied to the KVM server, and I can ssh into it with just ```ssh '[email protected]'

                              Did you run ssh-keygen -t rsa -b 4096 -C "KVM01_Root_SSHKey" on your KVM host as root?

                              Did you add the public key of your desktop to the /root/.ssh/authorized_keys file on your KVM host? (or whichever user qemu runs as)

                              If you're connecting virt-manager to your KVM host via SSH, you just need to have made sure to do the above steps... then when you add that KVM host to virt-manager, connect via SSH, type in root as the username (unless you set it up with another), then connect. NO password or anything (unless you used one on your private key).

                                This KVM issue keeps popping up from users every now and then I am talking about the root password prompts.
                                If I recall this is like 4th time I see topic opened for it

                                  Yeah. If you want to run as a non-root user, you need to add your user account to the group created for kvm (I'm blanking on what it's called and don't have access to my lab to check at the office here, doh!)

                                    And that's the user you defined in the connection for Virt-Manager?

                                    0_1512756412354_connection.png

                                    That user has to be part of the libvirt group if it's not root.

                                      keys are the best way to go.

                                        std config for libvirt doesn't allow non root to operate kvm. you must adjust it either changing the config or generating keys for root and run virt-manager with sudo

                                          Of course I can just create a directory on the server and then download ISO's directly into it. . .

                                          But I'd rather not. Hrm. . it works, but seems weird.

                                          Well I do not download from the KVM server, I do always have a "iso_store" folder on my KVM server that I have ISO files in.

                                          Sometimes it is a remote share mounted, most of the time it is local to the /root partition.

                                          Yea so what I did is I SSH'd to the server, and ran sudo mkdir /media/iso and then ran wget <url.iso> and it works. But it seems like the wrong way to have to do this. . .

                                          I think that's the way everyone does it.

                                            as @JaredBusch said. wget on local machine then scp to server iso folder (and set that folder as a libvirt storage)
