The Cockpit main package is for remote management of physical servers. They have the extra -machines and -containers in case you don't use those remote machines as a hypervisor or a container host. Modularity is flexibility at the expense of ease of use
VMs are saving my arse. With it help i learned to install Arch linux and right now I learn to install gentoo linux. And all this within a couple months thanks to RU-vid Tutorials and the second Lockdown here in germany. It is just so much fun. I love it. Thank you and thank you, linux community. You're the best.
I use cockpit with Debian trough OpenMediaVault and runs fine! Yesterday i bring a friend to Linux 😊 2021 is the Linux years my friends. Thanks to the shitty Windows updates you can see a lot of people jumping into libre boats hehe. Perhaps the Stallman GNU dance makes this possible 😋
I use cockpit to manage my VMs, Containers, and two physical servers. Because it's a server management interface. Not a Virtual Machine Managment suite.
The intro might be a bit confusing for people who are new to KVM, because virt-manager is very well able to connect to remote hosts. It does so pretty well too, i.e. by supporting SSH tunnels.
Oh cool, I had only ever used cockpit to check logs and restart services. It comes on with Fedora Server. I have never used it to manage virtual machines though.
Cockpit can just manage raw machines, servers or desktops. You could use cockpit to manage a house full of systems from one seat. I believe it might run across distros. Thanks for a great video.
I like the idea of Cockpit. Hopefully it gets fleshed out a bit more. I've been planning to either build or buy an old rack server (maybe an r620) to VM some stuff like a PiHole, Windows Deployment Server (for when family inevitably gets malware'd), and various nix machines. So far the best suited software for management has looked to be Proxmox but maybe Cockpit will eventually prove a nice alternative. I can definitely see how it's already overkill for just fiddling with a handful of VMs locally but I dig the networking integration even if I'll likely never tie anything remote into the mix.
I use virt-manager all the time to manage local and several dozen remote VMs running on various servers. I manage my MAAS nodes with virt-manager that sit inside a local container and a remote MAAS region controller, it works great, and secure, and I can do that without the need to install, load and use a web browser. Cheap web interfaces to these tools are really considered legacy at this point. Also look into Boxes, a GNOME project that replaces virt-manager.
That is what I was thinking while seeing this. I wonder what's the difference between using proxmox and just a relatively basic arch installation with these packages though.
Proxmox and Cockpit are enterprise tools, not really user tools.. Yes you can use them singularly on your home system for your one or two VMS, but where they really shine is when you have to deploy and service a few hundred systems.
If i am right then the Cockpit is the Fedora Server UI you can get out of the box. But to extend the basic functionality you need to install modules. You can get module to manage containers as well. And some other modules. I see some similarity to Webmin/Virtualmin project. Also i think there is something similar for Ubuntu servers. I believe once they will get the architecture right, there will be standard API to develop your own modules, let's say to manage specific software like Bind, DHCP, PXE, etc, etc. Just a speculation.
Nice video DT, actually i didn't now that Red Hat is the dev. Funny thing it's embedded on openmediavault as a special tool along with portainer and other things and it actually works just fine :)
You definitely don't need two computers for Proxmox, I've got it installed on a single server with the default installation method. Highly recommend if you need something that can do nearly everything.
Why would the resulting VMs only be accessible through a browser? As far as I know KVM-QEMU uses spice - remote-viewer spice://127.0.0.1:5900 most of the time I just use SSH after setup anyway
So, they are adding features to the 'old' cockpit which I used to manage Headless Fedora servers. Which was a cool tool. I think you can install it on Ubuntu Server too...
WHAT!? I just spend the weekend setting up Virt-Manager :(. Is it still "usable" or because it is deprecated for so long, I should use something that is maintained?
They also got rid of Spice protocol in RHEL 9. No audio, No local filesystem sharing, No spice accelerated video, no easy dynamic USB redirection. Big downgrade for those that used Spice extensively for desktop dev/IT.
Red Hat announced a year or so ago that they would deprecate Virt-Manager in favor of Cockpit: www.redhat.com/en/blog/managing-virtual-machines-rhel-8-web-console
Virt-manager is FOSS so as long as people want to contribute, it won't die. It's mainly that RHEL and it's derivatives are deprecating it. But keep using virt-manager if you want to. I know I plan to still use it.
@Mr. Rich B.O.B i agree with that but we need also a simple gui for simple users that do not use the command line and do not want to use a web tool with monitoring features that's is "bloat" for them.
Arch Wiki (Text) : wiki.archlinux.org/index.php/display_manager Video : ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-R2jgZErXeOI.html Though the video may appear aged to you, it is still relevant to today's techonology. Lightdm Customization: wiki.archlinux.org/index.php/LightDM 1. Install display manager (Lightdm, GDM, SDDM, etc.) Terminal: sudo pacman -S lightdm 2. Enable the service | Terminal command: sudo systemctl enable lightdm (You will type gdm, sddm, or the respective name if you select anything other than lightdm) 3. Reboot Lightdm Customization: wiki.archlinux.org/index.php/LightDM Greeter Used in example: lightdm-slick-greeter 1. Install a greeter for lightdm | yay -S lightdm-slick-greeter --noconfirm (paru will suffice as well) 2. sudo vim /etc/lightdm/lightdm.conf (You can replace vim with your favorite text editor such as nano) 3. Edit the line that contains greeter-session (Use "/text" in normal mode to search for specific text) 3b. Command to discover which greeters are installed: ls -1 /usr/share/xgreeters/ 4. Reboot This information is contained within the Arch Wiki and is still relevant to today's technology. Startx is used whenever display managers are not. wiki.archlinux.org/index.php/Xinit You will have to install xorg-xinit. (sudo pacman -S xorg-xinit) Then copy the startx file to home directory | Terminal command: cp /etc/X11/xinit/xinitrc ~/.xinitrc Then use the text editor (vim, nano, etc.) in order to edit the .xinitrc file. The last line must contain the "exec window manager/desktop environment" (openbox-session, /usr/bin/qtile start) If the other lines are unnecessary, you can delete them. The default configuration will remain in /etc/X11/xinit/xinitrc in case you with to refer to that configuration.
Qemu(kvm) / virt-manager isn't faster for desktop, only stated to be for servers, VirtualBox is more optimized for that(desktop), which I also found, and clearly saw a diff on lower powered(2gb 2cores) vms. Virtualbox has a complete cli interface which has more options than the gui, btw, so nicely scriptable no-matter requirements, hence I personally stick to that, though would prefer the more lightweight non-gui and kernel backed qemu/kvm, but I tried everything to make qemu comparable, but failed, I.e paravirtualized disk and network and propper drivers etc.
Dear Thanks for the great explanation! How can I manage Different Physical Hypervisors(Qemu/KVM)s from a single console ? I keep loggin in to the different physical Qemu/KVM to manage the VMs on it now and it is difficult, since we do have many Physical Hypervisiors (Qemu/KVM)
Fun fact: I almost distro hopped to Arch. (Un)fortunately, sudo worked (i was going to reset my main hdd due to the so files not being linked right). Also, i was considering using virt manager for testing my distro, but Im glad you told us that its deprecated beforehand. Nevertheless, I'll still use it Edit: Just got manjaro. Never going back.
Overkill, DT! Cockpit is an enterprise level virtual management tool and your using it for local user use...Such Bloat! Luke Smith would not approve! You might as well advise people to kill houseflys with shotguns...lol.
Have you ever successfully created a VM through cockpit-machines interface? Every time I try it, when I finish SO installation e reboot, got message stating virtual HD is not bootable.
Why is your CPU running at 80C? or is that F? If its C id look into a better cooler, or at least clean out some dust. Wouldnt wanna run such a expensive cpu at those temps at any time really :)
Something about NVIDIA released virtual upgrade for gpus it wasnt really an upgrade they blocked GTX cards for ages now its availble linux virtual machines . EDIT - Look up - * Dummie plugs hdmi- 4k increase GPU by 30% used on Bitcoin machines eg- 6x rtx 3060s 1 IS plug in Monitor the others all Dummie plugs = +30% hashing 💯
