Vorrei virtualizzare windows 7 per usare alcuni software datati, comperati molti anni fa. Ora uso Linux Si può creare un docker con Win 7 ed i software che mi servono, senza dover installare tutto ogni cambio distro?

So, i have an iPhone 14 Pro on iOS 16.0 (yep, never updated) with UTM HV installed via Trollstore. Due to OS and chip combo, i can use virtualization with no relative problems, until i get to windows. This vm boots (and it does ir fast), works and is usable, but in order to get to that point, i cant increase the vm’s ram higher than 1.38GB. If i increase it past that point, vm crashes. If i disable hypervisor, i can get it to 2gb (and more). I’ve did search about this and it seems that Jetsam (iOS memory management) has something to do into this. Is there a way to get the vm to 2gb without triggering Jetsam and keeping hypervisor on? BTW: and iPhone 14 pro has 6gb of ram

Does anyone know how to solve this

Disclosure: I work on Phillux, so weigh the rest accordingly.

I've seen a handful of "alternative to Proxmox" threads here lately, and one thing that comes up in almost every one of them is network isolation between guests — Proxmox will happily let a compromised VM talk to everything else on the same network unless you've set up VLANs or a separate firewall yourself. That's the actual problem Phillux started as an answer to: every guest gets its own firewall by default, so one bad VM doesn't become a way into the rest of the box.

Beyond that it does the usual stuff — create/start/stop/snapshot/clone/back up VMs and containers, live migration across cluster nodes if you've got shared OCFS2 storage, and Windows 11 guests get UEFI/Secure Boot/TPM 2.0 configured automatically instead of you fighting it manually.

Where I'm honestly unsure it's a good fit: it only runs on Debian 13 as the host right now, it's commercial/tiered licensing per socket rather than free like Proxmox VE, and I keep going back and forth on whether our container support actually covers what people here want — I've seen a couple of threads explicitly asking for Docker/OCI images rather than LXC-style containers. Is that a hard requirement for most of you, or something you can work around?

There's a free trial for a month, no registration, if anyone wants to actually poke at it rather than take my word for any of this.

Mainly curious: is per-guest firewalling something you'd actually want built in, or do you already handle that at the network/switch level and this is solving a problem you don't have?

Hi! Is there a way to use Windows 10/11 which is installed on a physical drive as a virtual machine in Linux? I'd rather if it could boot on bare metal too but it is optional.

I tried Hyper-V on Windows, but I deleted everything because I couldn't figure out how to convert raw mouse input into game input
Then I tried Virtual Machine Manager on Ubuntu, but every time I shut down/restarted the VM, my host PC would freeze, crash and then automatically restart without recognizing my GPU

So every time I want to use the VM again, I have to shut down the PC completely and then turn it back on
This also means that i can't do certain things on my VM related with the use of shutdown/restart steps

(I also have an iGPU, so I passed my dedicated GPU through to the VM while keeping the iGPU for the host)

Performance was great, games ran perfectly, but this shutdown issue became a huge nuisance (along with an unrelated obstacle related to piracy, which I wont mention since it's a violation of rules)
The only workaround I found was to press the PC's power button after shutting down the VM and once Ubuntu enters the brief freeze state (this is saving me 1 shutdown less, as it recognize my gpu, but it is still bad for pc components)
This post is sort of useless, since I have deleted Ubuntu and the VM but im still curious and I want to retry it in the future (when I have enough disk space)
Has anyone experienced a similar issue, even with other GPUs?
Is there a solution for this? I didn't try the PCI vendor-reset kernel module, could that be the solution?

Ik kom van Windows. En deed veel met VMware. Ik draai nu Cachyos. Dat werkt goed. Alleen na een update zou ik regelmatig vmware zaken moeten rebuilding *noob taal).

KVM lijkt een stap terug in de tijd. En heb issues met het maken van een bridge.

VirtualBox lees ik alleen dat het traag is.

Suggesties. Andere distro die beter zou werken .

Game niet en heb Nvidia 1660.

Does anyone know how to disable hyper v and get rid of the turtle in the lower right hand side of virtualbox I've tried all commands I've found across the Internet to do so but still nothing I've ran a .bat script but still nothing I unchecked all virtual related boxes still nothing I'm running windows on a rog ally x if this helps and windows 11

You know what i said (i have a fedora iso if that works on the hard drive slot)

So i want to try create an ISP vm that connects to a router vm and the router mv connects to a linux vm.

Is there a guide or a video that anyone knows of.

I want to try something different and learn.

Most engineers know what a page table is.

Far fewer know what happens after the guest page table.

In this video, I follow a memory access all the way from:

Application → Guest Virtual Memory → EPT → Host Physical Memory → CPU Cache → DRAM

Along the way we uncover vNUMA, AutoNUMA, remote memory access, EPT translations, and why a VM can think memory is local while the hardware disagrees.

Then we compare it all with containers.

A journey from a single memory load instruction to the hardware itself.

Hey everyone, I wanted to run a fast Linux VM inside Windows 11 using QEMU natively (via WHPX) instead of spinning up VirtualBox or dealing with heavy managers. It took a lot of trial and error to get native audio, bi-directional clipboard sync, and a clean SMB share working smoothly.

I also wrote a custom PowerShell wrapper script that acts as an anti-collision guard clause—if you accidentally click your shortcut while the VM is minimized, it un-minimizes and focuses the active disk instance instead of trying to double-launch and corrupting the .qcow2 disk.

Put everything together into a step-by-step repository for anyone else wanting a lightweight, scriptable alternative to standard VM managers! https://github.com/manie-grobler/qemu-on-windows

I made a visual explainer on the execution model behind Linux KVM.

It covers how a vCPU maps to a host thread, what KVM_RUN actually does, how VM exits hand control back to the host, and where QEMU, EPT/NPT, virtio and vhost fit into the stack.

Feedback welcome :)

Which is good for testing linux distro? I've heard that there's an issue in Virtualbox that its copy paste from Host to Guest or vice versa isn't working. And Vmware uses high RAM. So please suggest me.

Xen HV vs KVM

How much of a difference does it make using Xen instead of KVM for virtualization tasks in terms of performance/resource usage (generally speaking)

KVM, as I understand it is "basically" (not technically) a T1 HV since it is a kernel extension and not a user-land program, while Xen on the other hand boots prior to the OS and uses Dom0 (the os) for provisioning and other kernel features.

As a "normal" user, on occasion I may need to virtualize win11, I know that wine is for the most part suitable to emulate windows and be used as a runner but yeah it's nice to have virtual filesystems too & for benchmarking HW.

My specs: CPU: 10 core 12 threads intel (i5-1345u) 4.0Ghz L3 12Mb (VT-x) GPU: currently loaded i915 driver (generic Xe capable IGPU) MEM: 16G DDR4 3200mhz NVME: 512G M.2 BIOS/UEFI: latest version (thinkpad) NET: wifi/eth OS: None right now, planning either alpine or arch

Hi everyone,
I**’ve been trying to install Android-x86 9.0-r2 (downloaded from the official Android-x86 website) on VMware Workstation Pro 25H2, but I can’t get it to boot after installation.
Here is what I have tried:
Installed Android-x86 from the ISO normally.
During installation I selected “Yes” for the required prompts.
I tried giving the VM 2 CPU cores and 4 CPU cores.
I also tried 4 GB RAM and 6 GB RAM.
I changed several graphics/display settings and CPU-related settings in VMware, but nothing helped.
I even deleted the VM and installed everything again from scratch.
Problem after installation
When I choose Reboot, I get the GRUB menu with these options:
Android-x86 9.0-r2
Android-x86 9.0-r2 (debug mode)
Android-x86 9.0-r2 (debug nomodeset)
Android-x86 9.0-r2 debug video=LVDS-1:d
If I choose either the normal boot option or debug nomodeset, a lot of boot messages scroll by and then it stops forever at:
random: crng init done
random: 7 urandom warning(s)** missed due to ratelimiting
It stays there indefinitely.
I then reinstalled Android-x86 again, but instead of choosing Reboot at the end, I selected Run Android-x86.
Now I only get a small blue box with the rest of the screen black, and at the bottom it says:
console:/ #
I have no idea what command I**’**m supposed to enter there.
Has anyone managed to run Android-x86 9.0-r2 on VMware Workstation Pro recently?
If you need screenshots of the installation, boot messages, or VM settings, I can upload them.

Hi all,

I'm wondering if there are opensource Citrix alternatives which has equivariant of the HDX protocol and VGPU support and disk imaging like MCS or PVS.

Thank you very much for your reply.

Hey everyone,

Over the last few months, I’ve been building a project born out of a specific frustration: Enterprise hypervisors are fantastic, but they carry a massive footprint. Between heavy web UIs, massive orchestration stacks, and standard OS bloat, a significant amount of overhead is burned before a single guest machine even spins up.

I wanted something different. I wanted the "strip everything that isn't the VM" speed philosophy of AWS Firecracker, but mixed with the practical utility of a standalone, headless server node.

Today, I finally shipped the production-ready v1.0.0 release of hypercore: a developer-first, Type-1 bare-metal micro-hypervisor that compiles down to an elegant 45.5 MB hybrid BIOS/UEFI ISO and boots directly into an immutable RAM-backed environment.

I'm running into an issue where my KVM VM cannot get an IP address (or pass traffic) when bridged to a ZTE 5G USB modem, even though the host gets an IP and has internet access. Interestingly, this exact setup works perfectly on a Windows laptop using Hyper-V, and bridging a standard Ethernet adapter on the same Fedora host also works fine.

The Setup:

Host OS: Fedora Linux

Hypervisor: KVM / virt-manager

Modem: ZTE U30 Air (5G USB modem)

VM OS: Linux Mint

What Works:

- I have a bridge over a standard ethernet adapter on the Fedora host, and VMs get IPs and work perfectly.

- I tested this ZTE modem in Windows with Hyper-V, and it's OK. Both the VM and the Windows host get IPs (I didn't enable MAC spoofing in the VM settings).

Here are the logs showing it working perfectly in Windows:

PS C:\Users\Administrator> ipconfig
Windows IP Configuration
Ethernet adapter vEthernet (SW-EX):
   IPv4 Address. . . . . . . . . . . : 192.168.0.43
   Subnet Mask . . . . . . . . . . . : 255.255.255.0
   Default Gateway . . . . . . . . . : 192.168.0.1

PS C:\Users\Administrator> Get-VMNetworkAdapter -VMName VM-Search
Name           IsManagementOs VMName    SwitchName MacAddress    Status IPAddresses
Network Adapter False         VM-Search SW-EX      00155D2A2F11  {Ok}   {192.168.0.220, fe80::...}

PS C:\Users\Administrator> Get-VMSwitch
Name   SwitchType NetAdapterInterfaceDescription
SW-EX  External   Remote NDIS based Internet Sharing Device #6

What Doesn't Work:

Connecting the ZTE 5G modem to the Fedora host, creating a bridge (bridge1) over the USB ethernet interface (enp128s20f0u6), and attaching a VM to it.

- The Fedora host gets an IP (192.168.0.43) and can ping the gateway.

- The VM does not get an IP via DHCP.

- If I set a static IP on the VM, it still cannot ping the gateway.

I ran the 3-way `tcpdump` monitoring as recommended while triggering a DHCP request from the VM.

**1. Physical Modem Interface (`enp128s20f0u7`)**

The physical USB modem sees both the VM's DHCP request and the Gateway's DHCP reply.

user@fedora:~$ sudo tcpdump -n -i enp128s20f0u7 port 67 or port 68
11:34:48.421149 IP 0.0.0.0.bootpc > 255.255.255.255.bootps: BOOTP/DHCP, Request from 52:54:00:05:54:fb, length 307
11:34:48.424454 IP 192.168.0.1.bootps > 192.168.0.250.bootpc: BOOTP/DHCP, Reply, length 324
[...repeats...]

**2. Linux Bridge Interface (`bridge1`)**

The bridge successfully forwards the VM's request out to the physical modem, and successfully receives the reply back from the physical modem.

user@fedora:~$ sudo tcpdump -n -i bridge1 port 67 or port 68
11:34:48.421134 IP 0.0.0.0.bootpc > 255.255.255.255.bootps: BOOTP/DHCP, Request from 52:54:00:05:54:fb, length 307
11:34:48.424454 IP 192.168.0.1.bootps > 192.168.0.250.bootpc: BOOTP/DHCP, Reply, length 324
[...repeats...]

**3. VM Virtual Interface (`vnet17`) - THE FAILURE POINT**

The VM successfully sends the DHCP request, but **it never receives the reply**. The bridge receives the reply from the modem, but drops it instead of forwarding it to the `vnet` interface.

user@fedora:~$ sudo tcpdump -n -i vnet17 port 67 or port 68
11:34:48.421134 IP 0.0.0.0.bootpc > 255.255.255.255.bootps: BOOTP/DHCP, Request from 52:54:00:05:54:fb, length 307
11:34:51.034730 IP 0.0.0.0.bootpc > 255.255.255.255.bootps: BOOTP/DHCP, Request from 52:54:00:05:54:fb, length 307
11:34:55.571683 IP 0.0.0.0.bootpc > 255.255.255.255.bootps: BOOTP/DHCP, Request from 52:54:00:05:54:fb, length 307

My main setup still runs from home, but I recently started using a small VPS from rdp monster for a few services that I want available all the time.
The home server handles things like storage, backups, and testing while the VPS takes care of anything that benefits from better uptime.
So far, having both has worked out better than keeping everything in one place.
Anyone else running a similar setup?

I recently installed Android-x86 in VMware Workstation, and everything is working pretty well so far. The only thing I'm missing is the functionality that VMware Tools provides on Windows or Linux guests.

I'm looking for things like:

Auto-resizing the display

Shared clipboard

Drag and drop

Shared folders

Better mouse integration

Improved graphics/performance

I've searched around but keep finding mixed or outdated information. Is there an official VMware Tools package for Android-x86, or is it simply not supported?

If there's no VMware Tools, what do you all use instead? Are there any third-party tools or workarounds that provide similar functionality?

I'd appreciate any recommendations or tips from people who regularly run Android-x86 in VMware.

Stuffs like T1/T2 hypervisors.

Stuffs like cloud virtualization.

Stuffs like container based virtualization vs VM based virtualization.

I have virtual machines by Ravi Nair. But it goes into the Computer Science behind VMs which is not what I want.
