Manage KVM through Cockpit

Sorry if this is a dumb question, I'm very new at Linux in general.

When adding a VM, where do you tell it to store the VM at?

I make another partition and mount it to /data

Ok, I have the file system setup with plenty of space in /var

Trying to install using Cockpit:

@Obsolesce The file is on a USB Drive if that matters.

The ISO might need to have the correct SELinux context. Try copying it to your /var/lib/libvirt/images directory and see if it lets you install that way.

/var/lib/libvirt/images

That's the trick, thanks!

Now the next issue... Appears as if Server 2012 R2 needs a driver to see the filesystem...

I'm guessing you need to set the qcow2 disk to IDE instead of virtio. Then in the VM install the virtio drivers and you can change it back.

I've never installed 2012 R2 in KVM yet. But Windows 10 automatically sets up as IDE when done from virt-manager

I think I have it figured out but don't know how to actually implement it. I'm running Fedora Server 28 Headless - so I have the ISO file for the drivers in /usr/share/virtio-win

I think I just need to mount the ISO for the VM but not sure how to do that.

I run Fedora on my desktop as well as my KVM server. so I just use Virtual Machine Manager most of the time.

@jaredbusch Any idea how to do it in command line?

Easiest for a first timer is virt-manager. Just click the IDE CDROM device and then click connect. You can pick your ISO from the browser.

Can you use virt-manager on a headless install?

You use virt-manager locally.

I get this error in terminal in cockpit as well as locally.

Also, I fucking hate this phrase.

WTF is that supposed to mean? FFS, an install is an install. Ever single modern Linux distro runs just find without a KVM attached.

I installed Fedora Server 28 Minimal. and then disconnected the KVM and never hooked it back up. That makes it headless. But I did not choose some stupid "headless" version of the install.

Yeah. You can either X11 forward from the remote system or use a local install and SSH/HTTP/HTTPS for the QEMU connection.

Sadly virt-manager is the easiest for some things like attaching ISOs. The domain has to be running to attach an ISO however you can't hotplug an IDE device. So you're left with editing the XML for the domain. It's not hard just virsh edit vmname but still annoying.
