First of all, backup your virtual machines, as they are, before trying this stuff. For windows virtual machines, I will sometime de-fragment the virtual drives prior to zero-ing out free space using sdelete: sdelete64.exe -z c: This is a prerequisite if you intend to shrink a dynamically-allocated virtual disk. Yet, even if you don't shrink them, de-...

Starting the VM from VirtualBox itself you can choose Detachable Start: This will bring Detach GUI -option to the VM menu: This also gives an additional shutdown option that just closes the GUI but leaves the VM running: To start the VM with detachable GUI on commandline, use command VBoxManage startvm <VMNAME> --type separate. This also works when ...

As a workaround, after using: VBoxSDL --startvm Win10 --separate from a putty command line, I close the GUI by Ctrl+C at that command line, followed by: pkill VBoxSVC -9 Thereby, the Virtual Machine seems to continue in the background the whole time and I might be able to open the GUI again in the same manner.

You can use a USB Key to transfer files (enable USB Passthrough). The safest way is to burn a DVD on the host with the malware included, then read the DVD on the guest or vice versa. Internet, Networking (file sharing), or physical devices are the only ways. DVD is the safest. Alternative Approach: Since allowing a machine with virtual machines access to the ...

Sorry for the thread necromancy, but I fixed it in case, anyone comes across this thread from DDG (as I did), on arch with sudo pacman -Syu linux-headers and a restart.

-S says "don't actually start running the guest". So it is expected that nothing happens, and in particular that the guest hasn't done anything to program the graphics device to display anything. QEMU is waiting for you to attach a debugger to the gdb stub, and then tell QEMU to start via gdb's "continue" command. (It is also possible to ...

The solution is to add an IDE controller and select your Windows XP iso and do NOT use an SCSI controller. If you already have the SCSI controller, DELETE it and add the IDE instead.

Easy Switching? no, just boot into Linux and access Windows partition from there. Linux can R/W NTFS via the NTFS-3G pkg but Windows cannot see Linux. No Special partitions or magic required.

Use a thumb drive or a shared directory / partition on the windows side for your code shared with your VM and duplicate that share on the Linux VM. Linux can access (R,W,X) everything in the Windows partition / drive via the ntfs-3g package but Windows cannot see or access anything on the Linux side so that is why you set up the initial share on the windows ...

The Azure VM are already virtualized, and only in combination of HyperV Therefore, there is no hardware accel available But you may use qemu as an emulator ( so is not VMWare ) But the latest versions of WMWare 16 should ( need to test ) be integrated side by side with HyperV

Explanation: This is caused by the WLMS (Windows License Monitoring Service). Some suggested to try: slmgr /rearm, which will only temporary fix this issue, but you will need to run this every 30 days or so, and it didn't seem to work on my machine. (Windows 10 x64 Virtualbox) Permanent solution (and the only thing that worked in my case) is to delete WLMS ...

You do not HAVE TO add the tag unless you do not want it on your desktop. If it works with it then that's great for you, but from my experience Sandbox prefers your location to not have the / after the folder at the end. My 1st one ran where maybe 1 in 5 times the mapped folder wouldn't be there & I'd just close & restart. Then I removed the ...

Mir Rahed Uddin's answer work for me!!! Originally, my 「reinstall vm tool」 option was greyed out. But I followed the following command which was from Mir Rahed. sudo apt remove --auto-remove open-vm-tools sudo apt purge open-vm-tools The 「reinstall vm tool」 option was not greyed out anymore. It was turned to install vm tool option. So I click the option. ...

I had the same error Could not find an open hard disk with UUID {ab625445-c564-4ed5-ab89-2a3e75de7d6c}. The solution which worked for me was simply to execute the following command: cd ~/VirtualBox VMs/Win7-VirtualBox/Snapshots VBoxManage showhdinfo \{ab625445-c564-4ed5-ab89-2a3e75de7d6c\}.vdi After that the problem was gone and it works again very well. :-) ...

Parallels can only snapshot a running VM. See https://kb.parallels.com/5691 I don't know whether you could run the VM without the Windows installation recognising that as its 'first launch' date or whether that would survive so long as you don't run through the entire setup procedure. If you want to preserve the exact state before first run, I'd just ...

Had an SOB time converting this. I had backed up all of my hyperv's before moving to linux, only to find out you have to specifically export them from Hyper-v in the vhd format. After getting on linux I realized virtualbox doesn't support vhdx. I had to boot a windows 10 VM, move the files over, install hyper-v and all associated components, just to convert ...

Yes, this exists, though it's vendor-specific (just like CPU virtualization) and it tends to be limited to a separate product line – both AMD and NVIDIA have separate "data center" or "virtualization-oriented" products. The audience seems to be mostly companies which use virtualization for centrally hosting everyone's workstations (i.e. ...

VirtualBox is a general-purpose full virtualizer for x86 hardware. It might not function correctly on other hardware (e.g. cannot run x64 guests). Disable hardware acceleration in VirtualBox to fix some problems. That is often (well, sometimes) a cure for virtualization failures. Both Intel and AMD add dedicated tools for virtualisation into their processors,...

The obvious solution is to run Windows XP, not Windows 7, in the virtual machine. It's perfectly safe to connect your virtual machine to the internet. Your emulated Windows XP is running in a 'sandbox', and, although it's exposed to the internet, if a virus was to run within the virtual machine it could only compromise Windows XP. It couldn't affect Windows ...

The problem is the nested virtualization not being supported (meaning: you can't run a VM inside a VM; Windows Virtual PC mode is a VM for all intended purposes, it's even in the name). You may need to run it in a native Windows XP VM, just don't allow it to connect to the internet, but the same goes for the now defunct Windows 7. A better solution is to use ...

Vmware 15.5+ will work even if Hyper-v is enabled With the release of VMware Workstation/Player 15.5.5, we are very excited and proud to announce support for Windows hosts with Hyper-V mode enabled! As you may know, this is a joint project from both Microsoft and VMware.

You install Firmware and UEFI in the Host Machine and not in the Virtual Machine. Make sure your host is set for UEFI and Secure Boot and that works. Then install your Virtual Machine (any machine VMware supports) and it will use the VMware machine for hardware and devices. That is how Virtual Machines work. I posted this from my Kali virtual machine inside ...

Let's start with a note that WSL2 is running in a virtual machine (whereas WSL1 did not). It makes use of some of the underlying features of Hyper-V, but it is not Hyper-V. However, since they use the same hypervisor, they can coexist happily, unlike some other VM platforms. WSL2 is not, however, a virtual machine platform like Hyper-V where you can create ...

WSL and Hyper-V (or VMware) are two different things. WSL is a facility to permit running Linux Commands in Windows. The GUI interface also helps manage documents and things you may wish to do. But it is not a full fledged Virtual Machine and does not function like one. Notably the WSL interface is owned by the WSL terminal and cannot be restarted or shut ...

If you still have your original VM on your laptop, a better way to move it to a new host is to export it as an OVA. In Virtualbox, click File | Export Appliance. That will generate a single .ova file. Then on your new host, click File | Import Appliance and point it to the OVA file.

I have used this procedure on both Windows 10 and Ubuntu 21.04 hosts with an Ubuntu guest. These instructions begin by copying the VM, so as to preserve a backup. These instructions use VMware Player, not Workstation, but I believe the steps are largely the same. Make sure VMware is not running. Copy the VM's entire folder. To copy in Ubuntu, I ran sudo ...

In my case, resolve of a locally defined name myserver.local was slow and was fixed by the following modification - 10.0.0.5 myserver.local alias.local # original config changed to (added ServerName and moved myserver.local to end of list) - 10.0.0.5 ServerName alias.local myserver.local # altered config Fixed the issue.

It appears VirtualBox no longer exposes this setting in the user interface. As mentioned in my comment, the real solution is to enable hardware-assisted virtualization for your PC. It not only offers much improved performance but is also required for 64-bit guests. Barring broken BIOS/UEFI implementations, any modern system should support Intel VT-x or AMD-V ...

I believe Windows 95 has SMBv1 file sharing, so you could enable it in Windows 10 and check if it works (see link). A simple-minded method to copy files into the VM would be to package your files in an ISO file and set it as the CD of the virtual machine. For a list of products that can create the ISO see the article How to Convert Folder to ISO on Windows ...

Windows 95 needs direct disk access - without getting too much into technical details, an image file is definitely needed to support that and there is no way around that. Some possible solutions: If you have networking working in the Windows 95 VM you can try using Windows file shares to get data in/out of the VM. I don't know how strong networking support ...

In my experience Windows can occasionally hang network devices(/connections) during sleep, or power reduction cycles, if you make no other changes but to reboot the Ubuntu server you may be looking for an issue outside of VirtualBox/Ubuntu directly into the mirky world of drivers, etc. It is possible that changing your power management settings in BIOS, or ...

I would look for problem in DHCP lease. Does it have enough time? Maybe it does not lease again the IP address? First of all you should look into /var/log/syslog for any errors and network related issues.

You can install a Mesa3D OpenGL DLL alongside the program you want to run and this will give you OpenGL 3 support. But this is a software renderer, so how useful it is will depend a lot on what you're trying to do with it. If it's something that has demanding 3D rendering requirements, it will not be useful. If it's something that has very low rendering ...
