VirtualBox window doesn’t scale up to full-screen - virtualbox

Sometimes my VirtualBox doesn’t scale up to full-screen and bloats to a very unpleasant stretched mode when I try to maximize the window it.
How do I fix it?

This normally happens when the Graphics controller configured in VirtualBox Display settings isn’t supported.
PS : Guest Extensions needs to be installed for this option to work properly. So install them from VirtualBox website (as per Host OS you have installed VirtualBox upon).
To fix this issue, stop the instance of VirtualBox Guest OS you wish to up-scale to full-screen.
Graphics Controller ==> VBoxSVGA
See settings at link below

VMWare Remote Console not showing any GUI Dialog on MacOS Mojave

Installed VMWare Remote Console 10.0.4 (latest as of writing this) on MacOS Mojave 10.14.3. installation went well, but running the app, nothing is shown on the Mac. seen some unanswered similar questions on VMWare forum here and added my question here. Have anyone seen the same issue and have a solution?
I may have sound something - when i go to a vSphere VM, i have two options: 'Launch Web Console' or 'Launch Remote Console' - if i click the latter, i get the application to open with the UI displaying as it should. so, unlike VMWare Horizon, Player and others, here it seems you need to connect to the VM first via browser, to open the desktop client. weird choice from VMware in my mind, but still some solution. See image below

virtualbox - virtualization is enabled but not working

Ok, I have the most recent version of virtualbox installed, my computer (HP) has an AMD A10, 64bit Windows 10 OS and 6Gb RAM.
I created a virtual machine with Windows 7, there I wanted to create a new virtual machine (a VM2 in a VM1), but I cant run it because I have no virtualization enabled in the VM1.
ok, so I checked the VM1 configuration and the virtualization is enabled in the virtualbox settings. I've tried with all the Paravirtualization interfaces and always having the Hardware Virtualization enabled (VT-x and AMD-V).
I really don't know why this is happening if this is all suposed to be enabled and there arent documentations of similar issues.
I tried changing the number of CPUs used by the VM1 and all the interfaces.
I seach for 2 days and nothing worked for me.. then i find the solution:
The problem is in Windows 10... u need to disable Hyper-V Manager ...
1) make sure in your BIOS cpu virtualization is enable.
2) open your CMD as administrator
3) in your desktop folder type bcdedit and look for hypervisorlaunchtype in the bottom ... if it is Auto or enable we need to disable it !!!!!!
See this picture
4) type in your cmd bcdedit /set hypervisorlaunchtype off
5) Restart your OS and be happy !!!
i know this is a old question ... but for everyone who have a similar problem i hope it helps !!
Turn off the core isolation security provided in the Windows Defender Security Centre.
I found that enabling it turn off your Intel Virtualization technology feature while it is enabled in BIOS.
Steps to follow:
1. Go to Windows Defender Security Centre.
2. Search for Device Security in the left Panel and click on it.
3. Now click on core isolation.
4. Turn off the memory intergrity security.
If it didnt turn off and show (This is managed by your device Administrator) then follow the steps by searching on google.
You may need to download a file and enter into registry to turn it Off. Just google it.
The answer is correct, however there is something worth mentioning:
Usually the Hyper-V Manager is enabled by Docker (Docker runs on top of HV Manager), in my case it only worked after :
Removing Docker
dism.exe /Online /Disable-Feature:Microsoft-Hyper-V
the command line will ask you to restart, then you will able to run VX images!
In my case, my os is windows 10, I enabled virtualization VTx and Vtd in BIOS, but it didn't work. After seaching online, I sovled this problem. Hope this can help people.
Press Windows key + X and select "Apps and Features".
Then click "Programs and Features" link.
Then click the "Turn Windows features on or off" link on the left pane.
Locate "Virtual Machine Plateform" option and check it.
(These two steps I'm not sure : Locate "Hyper-V" and "Windows Hypervisor Plateform" option and unmark them.)
Click OK to save the changes and reboot.
Below is the screenshot:
enable Virtualization
And you can check if it is working fine in task manager, in the performance tab you can see whether the virtualization enabled or not.

Wamp on Windows 7x64 causes graphical bugs in contextual windows and menus

Each time I launch WAMP on my Win7x64, I see some graphical bugs in windows ui, such as grayed menu on right-click window (anywhere), menus in app (Notepad++ for example) and so on.
The only way to restaure my initial configuration is to stop server and reboot pc... It's not really important but i can't find out why this issue is still there, even after having reinstall several versions..
Search and researches led to nowhere... am I the only one, THE CHOSEN ONE?
THX !
By the way my current wamp conf is : Apache 2.4.9, php 5.5.12, MySQl 5.6.17..

Unable to power on VMware

I installed VM ware recently now whenever i try to power on VMware it shows the below message:
"Not enough physical memory is available to power on this virtual machine with its configured settings.
To fix this problem, adjust the additional memory settings to allow more virtual machine memory to be swapped.
If you were able to power on this virtual machine on this host computer in the past, try rebooting the host computer. Rebooting may allow you to use slightly more host memory to run virtual machines."
I am not able to change the memory setting .It just shows an option to resume the virtual machine, All other options are disabled. I have by mistake increased the VM ware memory in run time .Could any one help?
For anyone who encountered this problem recently, please visit this link:

Go to Control Panel -> Programs -> Programs and Features,then uninstall the Windows 8.1 Update KB2995388 may help
--* Edit *--
The Optional Update for Windows 8.1 for x64-based Systems (KB2995388) published on 10/13/2014 may causes issues when running VMware Workstation on a Windows 8.1 host with it installed.
And a message saying "not enough physical memory" will be reported.
Because the VMware team hasn't fix the issue, you can follow steps below to uninstall the update to boot your virtual machine:
1.Go to Control Panel -> Programs -> Programs and Features, then select View installed updates at the top left corner.
2.Scroll down the list and locate Update for Microsoft Windows (KB2995388), select it and click on the Uninstall button.
3.Follow the steps to finish the uninstallation.
In the comment list, someone also reported a fix from VMware communities:
Open the config.ini file located at C:\ProgramData\VMware\VMware Workstation.
Add this line:
vmmon.disableHostParameters = "TRUE"
Save & reboot your PC
It sounds like your VM machine is in a suspended state. What you need to do is follow the steps outlined here in this help ticket. Do these steps while vmware is not running. And once you do this, start vmware again and then you should be able to edit your memory settings.
Run it in Administrator mode in Windows 8.1. Probably a Windows Update... Deleting the suspended state didn't work for me.
Before proceeding with any alternative solutions/workarounds, please always double ensure you have updated to the latest version of VMWare Player.
My machine was running VMWare Player, Version 6.0.*, and this issue was occurring (my local machine's Operating System is Windows 8.1). The relevant error(s) were resolved after updating to the latest build currently available, VMWare Player, Version 7.0 (Please note: I did not have to remove/uninstall any Windows Updates/Features)
Just spent a few hours trying to get my VMware to boot. Power flickered off enough to shut down the computer while the VMware was in suspension and recieved this message.
Make sure the update isn't installed. Make sure to follow the accepted answer. What made it work for me was:
Right click on your development name tab
Click on "Manage" and then "Clean up disk"
It worked for me. I'm not sure why it worked, but it was able to fix my issue. Didn't need to restart.
Follow these steps:
Close the VMware.
Select VMware icon.
Run VMware as Administrator.

Programatically detect if I'm in VirtualBox seamless mode

Is there a way to detect whether I'm in VirtualBox's seamless mode from a guest machine? Or is there any command line option from VBoxControl.exe to detect this that I'm not seeing?
If that can't happen, can I programatically detect if a guest is in seamless mode from the host?
There are several ways;
check what API access you have to the information reported by the device manager; if you are on a VBox guest, you'll find a couple of unusual devices (VBOX CD-ROM, VirtualBox Graphics Adapter, VBOX HARDDISK, VirtualBox system device). Already the PC's hostname is "VIRTUALBOX".
Another, quite similar source of information is the systeminfo command. Also there, several specific parameters would contain names or values defined by VBox
You could also check if VBox additions are installed; they leave trace in the program directory, in the registry reg:\HKEY_LOCAL_MACHINE\SOFTWARE\Oracle\VirtualBox Guest Additions and as a running task in the task manager.
