virtual machine

So far I've been using VM's only either for fun or for testing purposes. But now I need to use it rather heavily such that the guest will consume significantly more CPU resources than host. My CPU is quad core (no hyper threading), therefore only 4 cores available, out of these 4 I allocate 2...

I'm having trouble getting my KVM virtual machine to start automatically when my Ubuntu host boots up. The state of VM is always "Shutoff" unless I manually "Run" it. Details: Host OS: Linux Ubuntu 24.04 VM OS: Linux Ubuntu 24.04 fresh install Virtual Machine Manager version 4.1.0 virsh...

Hello, I downloaded Virtual Machine Manager to use multiple OSes on my laptop, and I made Windows 11 virtual machine. but the screen was too small...(640x480 in bios settings, 1280x800 in Windows settings. Native is 1920x1080) So I searched about this problem and it said "Go to bios>Device...

I'm just curious what VM software people recommend? Merits of this software? I've used VirtualBox from Oracle (and thought it was pretty slick), but there are other options out there. I've heard of Qemu... thinking I may give that a go, as I've heard it's sort of the Linux thing (?). So...

For a while now, I've been checking out other distros so I can eventually switch to one, and Nitrux is one I want to try. I downloaded Gnome Boxes because the description said it's very easy to set up VMs. The problem is every time I try to set up any distro in a VM, I get an error message...

Hello, all I am new and this is my first post. I'm glad to be here! I have been playing around, and reading/learning about, Linux the past several weeks. (I have a Raspberry Pi 400 I've been checking out and I have a small Lenovo laptop with Ubuntu). I have an ASUS 17" gaming laptop and I...

Because I've been using Mint for the last 10 years, I recently decided its time for a different change in pace. For my new distro, I want to try out Zorin, but every time I click on "create virtual machine from file", and then click on the iso, nothing happens.

Hello I am new to the site but the information you have on here is great. I have a question regarding virtual machine drives. I was cleaning up my files and deleted the .vdi for a machine I no longer wanted. The goal was to wipe it and then start over with the same machine type/OS. When I go...

Dear friends, I want to start using Linux. My hardware is a M1 MacBook Pro and I installed Kali under the actual Paralles version. I become aware of the first „little“ problems… .Mac Keyboard (where are the special keys…@…|…\…) I started thinking about investing money in a second notebook to...

I've been trying to solve this problem for days now. When I try to launch my Virtual Machine in Virtualbox 6.0 I get an error message: Failed to open a session for the virtual machine llllele. The virtual machine 'llllele' has terminated unexpectedly during startup with exit code 1 (0x1)...

Last night, I was running Ubuntu MATE in Virtualbox, and when I was installing updates for it, it ate up too many resources and severely slowed down my computer. Even though I am running relatively-old hardware, and I did close down any programs I wasn't using (as @Tolkem suggested in a previous...

I often keep a virtual machine running for relatively long periods of time, and after a while, the fan on my desktop gets loud (probably because it's using so much energy at the time). After I shut the VM down, the fan quiets down. I've been thinking about upgrading the hardware since its...

Ok here’s my problem : I broke my laptop so I have it hooked to my tv via hmdi. For some reason I can’t get the bottom icons (Firefox , etc ) on my host machine . So being as though I couldn’t click on Oracle VM I entered “ VBoxManage startvms “kali Linux”” on my host terminal .From there I had...

problem is. I don't know where to start or what to learn. the terminal? which distro should I start with and which one should I end on? obviously all this sounds very generic and over-asked, yet I'd like to clarify that I had prior experience with linux. Pop!_OS in particular, I used it for...

I hope whoever is reading this is doing well. The issue is that I am getting screen stuttering/lagging on some distributions when I run them as VMs using virt-manager. The issue occurs with distros like Fedora, Kali, and Manjaro. However, the VMs of Ubuntu and ParrotOS (I think it is based on...

I used to have two USBs: a SSD with my Kali Linux and a 16gb stick with Tails. I'm planning on creating a Tails VM so i can use the security this Linux distro provides, and i need to know what are the best network options (NAT? Host-only?) to pick and if using Kalitorify while changing the mac...

Hello, I want to make a script that monitorizes the cpu utilization and sends that data to a mysql database. I have two VMs made with ORACLE, they both can comunicate with eachother, I made a script using the top command on VM1 and on the VM2 I have installed myqsl server. I only found how to...

Hello, I have a personal project that includes some ideas of using Oracle VM, monitoring and some network commands. So far, I have two VMs that can communicate with eachother, I made a database using mysql on one of the VMs and on the other I want to access and see the database on a web server...
