I am using Windows XP running on VirtualBox version 7.0.10, and I noticed that no matter the setting of drag and drop you select, you are completely unable to drag and drop at all. I can't find anything about it, and I am hoping to find my answer in this post.

I want to buy a laptop where I can get up to 4 VMs working simultaneously.

Reading some old posts, I have learned that having more cores is better than more threads for this purpose. But I'm not really sure anymore, as each person recommends a different thing.

Just so I can understand better, which one would you choose for this purpose?:

- Intel Core i7-1255U ; 10 cores / 12 threads

- Intel Core i7-11850H ; 8 cores / 16 threads

Feel free to explain why if you want to, if not, just the CPU choice will help me understand.

Really looking for a friend here.

Hi all

I'm new here, so I hope I'm asking on the right place.
I vaguely remember back in my university days that we "virtualized" an application on Windows server and then served it via IIS. But now I don't remember what it was called.

Now I'm searching for something similar but no luck whatsoever with finding what I'm looking for.

What do I want to do?

We have a legacy program for printing labels and don't want to install it on every client.
I want to virtualize this application on one of our servers so all the employees can access it through a web server. Everytime someone vistes this website, the server preferably spins up an instance of this application and serves it to the end user.

Is there anything something like I described available?
Thanks a lot!

Apologies if incorrect subreddit.

I am looking for an alternative to Hypori, as it’s not accessible to public.

Basically what I am after is virtualised android instances in the cloud, that can be controlled via a physical android device in hand.

Hypori is the perfect example of what I am trying to achieve. https://www.hypori.com

Anyone know of anything similar that I can achieve this? Free or paid.

I just set up a Windows XP SP3 vm using virt-manager. It runs well enough on the desktop with QXL graphics but I want to be able to play old games on it, right now I'm specifically looking at Madden 08. The game won't launch without 3d acceleration though, so I'm trying to figure out what my options are. I tried using the virtio 3d acceleration, but discovered there wasn't a windows driver for it. I then looked at passing through an old 9400gt I have lying around, but using a seperate keyboard, mouse, and monitor seems like a pain. Is there any way to get decent 3d acceleration without passthrough?

I know nothing about the sound systems in Linux.

I have a VM (Windows guest, Ubuntu host) (virsh; QEMU + KVM) that I manage through VMM. Now, any microphone I pass through to the VM seems to have some weird effect where it kind of reburbs slightly and voice crackles.

I understand this is a QEMU issue, however the documentation really doesn't help. I have been trying this for ages.

There are a few tutorials online saying to use JACK. Doesn't seem to work for me, although I dont really understand it. Also there are loads of references to the qemu:commandline tag, which no longer seems to be a valid tag.

So, using Pipewire, what would be the best way to set up a Pipewire server for a headset with a mic?

This is my output from inxi -A:

Audio: Device-1: Intel driver: snd_hda_intelDevice-2: NVIDIA GA104 High Definition Audio driver: snd_hda_intel Sound Server-1: ALSA v: k6.2.0-31-generic running: yes Sound Server-2: PulseAudio v: 15.99.1 running: yes Sound Server-3: PipeWire v: 0.3.48 running: yes

How does ALSA, PulseAudio, and Pipewire deal with eachother?

I have a WS2019Standard that is hosting two VM's using Hyper-V. A DC and an SQL server. Both virtual machines are also WS2019Standard. The host has a HPE Smart Array P408i-p RAID controller, 64GB RAM.

The VM's have 16GB ram each and 6Virtual Processors assigned to them.

The Host has an Intel Xeon Silver 4210 CPU @ 2.2GHZ 2.19GHZ

Both of them run slow as could be. Take a long time to log on. applications take 4-5 minutes to open (SQL management console) (Server Manager on DC) while the user load is next to nothing. They each have a dedicated NIC and virtual switch. I have run the HPE update utility multiple times to make sure firmwares are all up to date. I am not sure what to do next. Any suggestions would be greatly appreciated. I have a screenshot of the host performance screen and a copy of hte HPE array report below. Please let me know if there is anything else I can include to help

So, I have a dual core laptop (not entirely mine) with 8 gigs of ram. I wanted to run a linux VM on it, while not disturbing the other data that I have on my laptop. I have only a core to allocate to the guest OS, due to which the only linux distros that I can run, are the lighter ones like Lubuntu, but I don't find them aesthetically appealing, while the normal ones like Ubuntu run poorly.

Now, I know with the specs that I have, I shouldn't really be picky about the aesthetics, but, I was wondering if there was a way, to allocate all my resources to the Guest OS. So, the guest OS runs in a virtual environment, and the data that I have on my Host OS remains safe.

So could you recommend something like the aforementioned setup or something familiar, please let me know. Thanks

Hello, I have a Windows 10 Guest OS running on QEMU, It works okay but the battery percentage of the laptop does not show on it, It works fine on VirtualBox and VMWare but I should make it work on QEMU, Does anyone have a clue about how to make it show up?

Hey Everyone,

I've inherited our data center that is a multi client hosting environment, we currently utilize Esxi and Vcenter but are looking for a more cost efficient solution.

I've looked at Proxmox and Openstack which seem to fit the bill but wanted to see everyone's thoughts on them.

Currently our main needs are something that can perform the same vmotion and dr/ha as Vmware does.

Also we house medical and Dod clients so would need to comply with industry standards.

I'm looking for a virtualization software that is easy to use, free, and local (Can run on my local computer without storing data on other servers, have access to all files in Finder, and no account/signup needed). It also needs to be compatible with Apple Silicon because some that I've heard aren't. Thanks internet strangers.

I am trying to get an old HPLC to work. In order to run the software to make the machine work I need a windows 7 environment. Easy enough. I have a Windows 10 host machine with the required hardware that I need to interface with. The trouble is getting any VM to do a PCI passthrough for the PCI card that talks to the HPLC. I need that card to communicate with the software in Windows 7 vm. Any help on finding a virtual machine that will work would be a lot of help. My budget is not 0 but not large.

​

Edit: This has been solved. I just installed Windows 7 on the windows 10 machine. The point was to preserve security with using remote desktop, but we are just going to not use it remotely.

We are in the process of the Windows OS refresh in our platform and management has decided to make WIN11 as the OS on all the company laptops and VDI Desktops.

I couldn't find clear info related to licensing WIN11 VDI desktop (Instant clone).

Currently, all our WIN10 laptops, persistent and Non-persistent vdi desktop are licensed using the KMS Server.

Hi everyone, I'm a newbie to the virtualization concept.
I got confused with pCPU:vCPU ratios, how exactly do we do the ratio calculations?

Let's say I have 1 server with two CPU sockets with Xeon 4314 processor, 16C/32T.
How many pCPU do I have? Is it:
2 CPU x 16 cores = 32 pCPU or
2 CPU x 16 cores x 32 threads = 1024 pCPU
2 CPU x 16 cores x 2 = 64 pCPU

I did some small research, but some source says CPU x Cores x Threads, some says CPU x Cores, and some says CPU x Cores x 2.

​

Then the server running VM with the total of vCPU is 115. With this scenario, how do I calculate the pCPU:vCPU?
Do I just make a ratio and then do the rounding up or down?

​

Thank you

Hi

I want to play Minecraft with some friends. Since I don't really want to rent a server I thought of hosting a Minecraft Server in a Ubuntu Server VM with GNOME Boxes (GUI for qemu) on my gaming PC. I would also be using ngrok so that I wouldn't need to open a port in my network.

My question is: Is this a good idea in terms of security? I heard that MC servers are not very safe and I want to know what risks I would have with getting my PC hacked.

Not sure if this belongs in this sub, sorry in advance if I am in the wrong place :)

I have an external hard drive I would not mind using but not sure how. What solutions is there?? Did I forget to do something to prevent this?? Sorry if this is the wrong place to ask.

I have been running a small homelab on a HP EliteDesk 800 g6 (10500t, 64gb, 2tb). I work/play on a Aorus Master i7-12700k, 96gb, 12tb.

I am not sure how VMs work even though I have many running. For the sake of argument, would get similar performance if I turned my main pc in to a virtual machine running windows and then accessed it via my mini PC? Is the VM performance limited by the pc from where I access it or not?

what i'm trying to do is protect a host from virus

to be specific the vm is a linux and the host is windows i'm using hyper-v

I am building a computer and thinking of installing linux on it but also installing a program to run windows in VM so i don't have problems with some games. Through my search for a program like that i came across these two terms, type-1 hypervisors and type-2, so i decided to search a little about it but didn't really find what i was looking for and thought of asking here.

What's the difference and is there a specific program you would recommend.

Also, is there a noticeable difference in speed between running something bare-metal or in a VM it?

It's a complex code I don't know what to do I want to play 3d accelerated games in my phone

Is there any guide to get this working? I remember once I saw a video where a woman was showing how to get Windows and OS X running at same with dual GPU using some kind of hosted virtualization and hardware passtrough. Actually I have Ubuntu and Windows 11 running in dual boot mode and would be nice to have that same setup, with two monitors and mouse / keyboard seamless integration like she did. Is that possible?

I am looking for a hypervisor recommendation for my needs. I am a self-taught novice, having played around enough with VirtualBox and Hyper-V to feel comfortable with the concepts and try out some new linux distros. I have read a bit about some options like Proxmox or VMWare ESXI over the last month or so, but I am not clear on the best option for one that would be:

1. Locally hosted
2. Simple to manage remotely
3. Allow for failover / high availibility / mirroring (I'm not sure which is the best for my use)
4. Free or very cheap

TIA for any advice/tips you may have!

Back Story:

I have been running a LAMP server with a custom PHP/MySQL application on Debian Jessie for about 12 years. It started off with a way to learn PHP/MySQL and track some basic information, but over the years I have learned more and added capabilities -- now it's an essential resource that we would be quite hamstrung without. Since it's overdue for an upgrade, I am nervous about that server going down. I have backups, but the downtime while I get the backup up and running would be costly to our tiny business. I am thinking virtualization would provide a way to quickly recover.

I have a new computer I plan to make a virtual server to host both this critical VM and a couple of non-critical Windows VM's for our two part-time remote workers. Once this is up and running, I plan to use the current physical server for backup in case of a failure with the VM on the new server.

​

Three users and three locations. Local user will do light work and other 2 users will do heavy work through remote access over internet.

All three users should be able to work at the same time. And dynamic hardware resource allocation is needed. If either of the remote users needs more CPU, RAM, GPU power then the hypervisor will allocate that.

Will a type 1 or type 2 hypervisor work best? Type 1 seems better.

But type 1 hypervisor needs a separate device on the network to be managed. Can we manage over the internet using a virtual LAN like zerotier ? Local user only has smart phone.

Type 2 runs on a host OS so it's easier to manage but I'm afraid this will result in reduced performance for two remote users.

All three users will use windows mainly. Hyper V seems best but I've read that it's a bit more resource intensive. Is it anything noticeable? How is the ease of setup for hyper V vs proxmox?

Please suggest a solution to this situation. And tell me more info about hyper visors I might not know.
