@@GWFO With virt-manager you can use kvm which is a type 1 hypervisor and thus runs very close to the hardware. Virtualbox on the otherhand is a type 2 Hypervisor which is running on top of your Operating System and is therefore slower. Also with kvm you can easily passtrough real hardware.

I have a Ryzen 3 2200G (4C4T) and I always give all VMs all 4 Cores. I see no reason to slow down a VM artificially, also because the Linux kernel of the Host is perfectly capable of scheduling the processes of the Host and the visible processes running on the cores of each VM. I only limit the number of CPUs for e.g Windows XP Home, because that OS only supports 1 core.

Virtualization is perfect for scenarios where you have to configure a piece of hardware with very dubious software running only on Windows. I luckily haven't run into this scenario for some time now but if I were using Windows I still would use a throwaway VM like this to configure the devices avoid permanent junk shitted all over your system.

@bertnijhof5413 Жыл бұрын

QEMU is an emulator and as an emulator it can emulate different hardware architectures (instruction-sets) including x86, MIPS64 (up to Release 6), SPARC (sun4m and sun4u), ARM (Integrator/CP and Versatile/PB), SuperH, PowerPC (PReP and Power Macintosh), ETRAX CRIS, MicroBlaze, and RISC-V. Virtualbox is NO EMULATOR, because unlike QEMU it can't emulate ARM instruction on your x86-PC! The hypervisors of KVM and Virtualbox both consists of 3 modules that run inside the Linux kernel.

@anon_y_mousse Жыл бұрын

For most people that won't matter and/or they won't care. If safety and security are a concern, obviously an emulator would be the best option because it mitigates attack vectors. If speed, not safety or security, is your main concern, then a hypervisor based VM would be your best bet. If you're a competitive gamer, obviously you'll want to go with a hypervisor based solution.

@@anon_y_mousse There are much better ways to protect your VM, while improving security and performance. Like suggested in the video, split up your work over more VMs, so only one VM gets infected. I have the next 6 main VMs and all VMs are closed for inbound traffic, except one: - Communication (Email; WhatsApp; etc), with a few open ports; - Banking, Ubuntu 16.04 ESM is encrypted by Virtualbox and used exclusively for banking, while Firefox uses the latest stable snap container; - Multimedia; - Try-outs and experiments; to concentrate the risks during experiments here and to avoid cluttering up the disks of other VMs with left-overs; - Windows 11 Pro, just in case I need it; - Windows XP to play the wma copies of my CDs and LPs with WoW and TrueBass effects. Note that I installed and activated the VM in March 2010 and it survived 3 desktops with 4 CPUs and 2 laptops :) Security: I run the VMs on the OpenZFS file system, so in case of any problem I rollback that VM. I had to use it once for an infection by Email. Performance: The VM runs from L1ARC, the ZFS memory cache, it is like running the VM from a RAM disk :) I used the Virtualbox encryption, because it was easy and convenient for one VM, you only have to remember one passphrase. However nowadays OpenZFS supports encryption for datasets (super folders) too.

Windows doesn't have the a KVM hypervisor, so you'll need a different hypervisor like Hyper-V. Passthrough can work, however you cannot share devices for use on both devices simultaneosly. E.g. you can't load a driver in a VM and use the device on the host

Linux also offers other alternatives short of full virtualization: for example, containers, in the form of LXC and Docker and systemd-nspawn. For example, I want to run up two versions of an application I built for a customer on their server -- one for production use, the other for testing. I put the testing version in a separate container, isolated from the production code. This way they can share some aspects of their configuration, while being isolated in other ways.

I wouldn’t attempt to use OpenGL on an Nvidia card if you have one. I believe it doesn’t work on purpose. Just thought I would mention it, so I hopefully save someone some headache. Also, I use a RDP software for my windows VMs like Remmia to just RDP directly into it. For me, it fixes a ton of stuttering in my windows vms. As a final note, on your windows machines, install Virtio drivers if you use virtio. Makes a handful of things either work, or work better!

9:52 I'm curious, what happens if you pass it through? Wouldn't it be sick if you could like launch an "app" that is really a shorcut from a Windows VM that runs the app and kinda "freezes" the guest OS? It would be a brute solution to run apps that won't work in Linux like Photoshop or some AntiCheat games. What about gaming latops with two GPUs? (One from the CPU integrated and the dedicated NVIDIA GPU) If I'm not mistaken, Mac does something similar integrating VM with the desktop itself. When the VM is powered off, it could restore the Guest OS to the previous state before passing the only GPU, something like an snapshot. Of course, even if this existed, it wouldn't be a real fix to programs not running on Linux, but it could make more people making the switch. Hence, the desktop scene would grow bigger. I am also pretty surprised that you didn't talk about VirtualBox.

@MichaelNROH Жыл бұрын

Passing through your active GPU can result in crashing the host operating system, it's Desktop Environment, or even the Guest OS, so it's best to do it before booting the Guest. If you have several GPUs then yeah, you could pass one through without many consequences though it should be noted that Windows VMs are still not tolerated by most Anti-Cheats. If detected, you will face a legitimate ban sadly.

If you have a guide on this, I would be very interested. I run only a single GPU (Radeon RX 6700XT) but if I can pass the GPU pretty easily then I can gain some graphical smoothness.

The one thing I can't replicate from VirtualBox is bridged networking, so that a VM can get its own IP via DHCP from the router and be accessible to other machines on the network, on a machine which connects to the router via Wifi and DHCP. The tutorials I've tried so far assume e.g. ethernet with a fixed IP, and so far I've only succeeded in totally messing up my Wifi config to the point that I needed to reinstall. VirtualBox fails to load VMs on some of my Linux boxes. So my main VM host is my Windows box for now.

If you want to create a disk without preoallocation you have to do it manually using command: qemu-img create -f qcow2 -o preallocation=off,compression_type=zstd /var/lib/libvirt/images/mylinux.qcow2 30g This will create a 30G disk with preallocation disabled and compression type zstd (it normally uses zlib which is slower).

Virtualisation in Linux is genuinely levels above Windows (even had way better experience on a lower spec hackintosh with Parrallels compared to a workstation grade computer running Windows). One thing I just can't seem to figure out how to do is to set up a virtual machine in Linux to boot a physical install of Windows (as it has so much stuff installed and configured on it that it would take weeks if not even an entire month to re-do from scratch on a brand new config), and I'd really be up to give up booting Windows on bare-metal fully.

If Proxmox uses around 1GB of RAM and is a Type 1 Hypervisor and Lubuntu with QUEMU/KVM uses around 0.5 GB RAM and also allows the kernal / bare metal virtualization. What are the performance bottle necks and performance differences between these two options?

@MichaelNROH 4 ай бұрын

RAM usage on Proxmox is handled differently than on regular distros because it's mean for pure virtualization. Many default settings have been tuned to optimize speeds for virtualization (e.g. ZFS ram cache is set to 50% by default). If you set all these settings on Lubuntu as well, then the story will be the same. It's all about finding a sweet spot between speed and compatibility. --- Most performance bottlenecks come from RAM and storage.

GPU passthrough plz in linux

@MichaelNROH 5 ай бұрын

I showed PCI device passthrough in my Proxmox tutorial: kzfaq.info/get/bejne/ir2IZsyIyNHFj2Q.htmlsi=KaY_gp0zuzqB0kA6 It's basically identical with the Virt-Manager in the hardware screen.

Yea I also recently got into Windows VMs with gpu passthrough. Cool that I don't need to dual boot for my VR games. Maybe will also look into installing photoshop on it as gimp is an utter trash

no matter what I did, my vm was slow for me, like with synthetic benchmarks and actually playing games, it was fine, but windows was generally quite slow, not to mention I didn't particularly enjoy handicapping my linux and to not be able to play games with kernel anticheat wasn't great either...

make sure to avoid getting vm banned. Suspicious hardware activity has started receiving bans as of late, so if you can make your virtualized machines look normal try to do that.

can we play RDR2 using this vm ?

@MichaelNROH 5 ай бұрын

I would not recommend it because of the performance hit in comparison to just running it just on Linux

For Virtual Machine Manager, I go a step forward and edit the CPU topology in the CPU settings for the VM. For some reason, after specifying the number of CPU cores, my VMs are configured to have the same number of CPU sockets as the number of cores I specified. I've noticed worse performance. So I always manually set the CPU topology: 1 socket, number of cores specified and 2 threads per core. I get better performance this way. Idk why this happens and I wonder if I'm even passing my CPU cores to the VM (which I'm guessing is the best yielding for performance). If someone can confirm if those cores are being passed through when setting up the topology manually would be greatly appreciated because I also see host-passthrough as an option but that option defaults to having multiple CPU sockets. Maybe I'm missing something here

@MyAmazingUsername Жыл бұрын

Your settings are bad. Now that I have your attention, "RFE: default VM topology to use cores instead of sockets #155" has the answers you seek. The short: Use 1 socket, X cores, 1 thread (never more than 1).

@@MyAmazingUsername What if I wanted the VM to think it has hyperthreading? Btw I tested it out between 1 thread and 2 and there is far less CPU usage for 2 threads, probably because of the 2 extra vcpus. I'm running a Windows VM. Performance seems to be the same so I'm guessing it is more of a limitation on graphics rather than processing power since I don't have 3D acceleration enabled

@MyAmazingUsername Жыл бұрын

@@pialdas6835 Read the reference I mentioned. :) But the short summary of the info you seek is: It will not use hyperthreading unless you manually pin every vCPU to real CPU cores. By default, hyperthreading is broken unless pinned to the correct physical cores, and you should therefore only use 1 thread per vCPU.

@Hello World Ah I see what you mean. Btw idk if I was supposed to click that #155 link but it basically points to me a bunch of youtube shorts. I tried to search up that phrase you had in quotes (although not extensively) and didn't get much useful information. I'll search up CPU core pinning and read up on it when I get the time to tinker with my VMs again Thanks for the help!

@@pialdas6835 Try it without the quotes, it's a Bugzilla discussion. But yes if you manage to pin the vCPUs you can enable multiple threads. I haven't bothered doing it though.

VirtualBox supports Linux right , why isn't it used ?

@MichaelNROH 9 ай бұрын

Because QEMU utilizes KVM and Virtual Box does not. It's therefore more performant. Some downsides would be scalability by default, but that's not a issue for 90% of use cases

There is no real difference anymore between modern type 1 and type 2 hypervisors. Nowadays the type-1 hypervisor has inherited a lot of standard OS functionality to be able to offer the functionality required in "state of the art" VM Host systems. Type 2 hypervisors are integrated in the kernel of the Host OS. So both type 1 and type 2 offer sophisticated OS functions integrated with the hypervisor. There is no difference in performance other than the difference in the quality of the implementation just like between different internet browsers.
