Preparing Machine Images for qemu/KVM

Building on our previous video around libvirt/qemu/kvm, now we'll explore the idea of creating base images we can clone. This enabled us to quickly create base images that are easy to replicate!

fantastic details for cloning machines without using same ip address this is vitally necessary to know....

[harunafaruk]

This is the best video on youtube about this topic I have found. It has help save me a ton of work. Thanks a lot

[ericgorder]

Thank you Josh! You did a well job of explaining everything. I never got bored and it was well worth my time!

[lamkask]

Amazing video as always!
Thank you for more in-depth explanation how all this works. This is certainly better way than "binding" the IP address to the server's MAC address.

[munir]

This is really COOL. I can't thank you enough to prepare such a video. Please keep doing :)

[varenneriocha]

Very valuable. Many thanks!

On a side note, your video technique is perfect: Terminal full-size and the talking-head with transparent background. ;-)

[anasir]

amazing explanation, easy, clear, and right on point. thanks a million

[krishnachaitanya]

Excellent Video! Taught me more in 20 mins than over 2 days of reading blogs and articles from google search. And a great companion blog to follow through.

Very helpful videos. I got into libvirt with your videos and had it up and running in no time. Bye bye to VirtualBox and expensive commercial tools I cannot afford. Thanks a lot and keep up the good work!

[davidllanes]

"pretty freaking cool" but very instructive and with a lot of different topics which show how you master them. Complementary web post is really appreciated. A cool feature would be to create a script that would be able not only to clone the image but also to automatically boot up the k8s cluster with one admin and the rest workers. Congratulations and thanks!

You can use hostnamectl to set the hostname without rebooting. For example you can set a hostname to "cool-new-vm" by running `sudo hostnamectl --transient hostname cool-new-vm`.

[Mrhennayo]

been struggling with the reason for like 2 weeks now!
thanks mate for the info

I'm very new to visualisation and this and your other video on libvirt really helped me understand what's going on. Great delivery, really clear and we'll prepared - and thanks for using a sensible font size on your terminal so we can read it! So many YouTubers omit that.

Would love to see a video on networking options in QEMU/KVM and/or libvirt. Thanks again and all the very best.

[scottseymour]

totally new to all of this, another great video! cheers :)

[arborrell]

Thanks again for a wonderful tutorial. The level of content, the exposition and quality production are very, very good. You've mentioned some kubernetes/ansible possible videos, I'll be looking for that, and would also like a video about migrating vm's to another machine.

[emmanuelaboagye]

Great Video. Thanks very much for the in-depth explanation. I would like to also request that you give a tutorial on automating the image preparation process as you mentioned during this video. It will be very helpful to me. Kudos..., the Best so far videos I have seen on libvirt-Qemu-KVM is from you.

[vandanasippy]

As usual, very informative. Simple workaround will be to clone the VM from existing VM. empty the /etc/machine-id file. change hostnamectl set-hostname <requried hostname> and restart the cloned machine. We have so many versions of VMs running, will be difficult to manage so many base images.

[GrahamAtDesk]

Awesome video, thank you! You've literally saved me hours with these two vids on libvirt.

[igielv]

What about using 'virt-sysprep' for cleaning up stuff from base image? ...otherwise pretty good job and still lot of cool ideas to take from your videos, really like them, keep up. 👍

[micleh]

Good or bad? - definitely good or rather excellent. Just seeing you tinker with kvm is awesome, and I learned a lot. If you intend to extend the kvm series, perhaps you can do a more ordinary example of setting up a vm correctly. In my workplace I need to use Windows or a Mac, but I don't want to install those on my machine. Perhaps you can show how to set them up with passthrough.
