Wtf is going on here... everyone is making it so difficult... it's not!
Step 1: On your KVM host, run the following command:
ssh-keygen -t rsa -b 4096 -C "KVM01_Root_SSHKey"Step 2: On your desktop/vm used to manage the KVM host, run the following command:
ssh-keygen -t rsa -b 4096 -C "PCName_userName_SSHKey"Step 3: On your desktop/VM, copy your public key:
cat /home/username/.ssh/id_rsa.pub
...then copy it.Step 4: On your KVM Host, paste what you copy in Step 3 into the file here:
vi /root/.ssh/authorized_keys
...then save the file.Step 5: On your desktop/VM using virt-manager, add the server like below... type in the host name then click connect.
No password required.But see doing it this way has skipped a bunch of stuff that
ssh-copy-iddoes. This will end up with more questions later on.I would be willing to be dollars to donuts if someone uses this they will have to change permissions on that authorized_keys file because it's not created by defualt.
Seriously just generate the key (RSA is the default):
ssh-keygen -b 4096and copy to the server:
ssh-copy-id user@serverYes, but this assumes you've already got SSH going and unsecure enough to do a ssh-copy-id to the server. This isn't the case for me.
But you are right, generally the ssh-copy-id is the way to go as I suppose I'm the only one here who does things securely, or this is done before securing SSH on the server.
hahahahaha. Wtf are you talking about. What does "unsecure enough to do a ssh-copy-id" possibly mean?

@stacksofplates I can break your 4096 bit encryption with $5.
If your worried about state-level actors you have bigger concerns

When I try to do a ssh-copy-id to my servers, I get this:
Permission denied (publickey,gssapi-keyex,gssapi-with-mic).This is expected, as I do not allow root logon, I do not allow password auth, and only allow RSA key based authentication.

Pst me your email and I'll give you a key to break.
Leave me an audit trail so I can confirm.

I use my user in the libvirt group so I do not have to bother with the root user.
gpasswd -a jbusch libvirtThen this works.

How did you get into that state? How do the initial keys get there?

Ok? We are talking about an initial hypervisor setup. Passwords are enabled by default. You copy your key, then shut the passwords off. Idk what the eff is going on here.....

Never tried it that way. I've always used:
usermod -a -G libvirt <username> -

On a physical hypervisor initial install. How do you do that?

Anyone who goes to a brick and mortar store.

THe cheapest one I found on Amazon is $4.22. Better hope that comes with free shipping.

See.... you'd just use a brick for a fraction of the price.
