I'm trying to access my MAMP hosts from VirtualBox, and problem seems to be that VirtualBox won't save my network settings.
Here's what I do:
Open up the settings for the snapshot and change the network settings to "Host-only Adapter", and press "OK".
Like this (screenshot)
But when I open up the settings right after pressing "OK" it still shows "NAT" as the network setting.

Is this a bug, or am I missing out on something here?
I used to have this problem and it was by luck I solved it!
The trick is to go to 'Machine' menu and click 'Discard saved state'. This error occurs because Virtualbox cannot change anything with the VM running.

Using vSphere Update Manager I've installed some updates and patches onto my host, however I have an issue with it picking up a datastore now so I want to roll back these changes to see if that fixes the issue.
From my research I understand that you can't uninstall these patches and you have to revert back to a previous ESXi version. I'm attempting to do this following the steps here: https://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=1033604
However it does not give reference on how to access the Console for the Host. I can't find a way to access it in vSphere, but found a way by downloading putty and running the DCUI command.
The problem I have is that it says Reboot and then:
When the Hypervisor progress bar starts loading, press Shift+R.
However when I reboot putty loses connection to the host (presumably because it is rebooting) so I never get to see the boot up screen and Hypervisor progress bar to press Shift+R.
Am I missing something simple here? Server is Dell running ESXi 5.5. Thank you.
Dell ilo interface shall provide you the recover(Shift+R) while rebooting and hence rollback option.
The default credentials for dell ilo would be,
username : root
pwd : calvin
The steps to achieve this would be as follow,
Get ur ILO link, please see if below link is useful to you in this regard.
https://www.dell.com/community/Systems-Management/How-to-get-the-DRAC-IP-address-from-the-localhost/td-p/2374426
otherway would be ping your server FQDN and it would return the ILO IP.
Once you find ilo url or IP, login to it using above mentioned default login credentials(root/calvin).
Now, in ILO interface find the option to launch the console (server -> Virtual console preview -> Launch).
Save the JNLP file and run it.
Further, Press F12 for "Shout down /restart"
Here onward I believe you will get it.
Thanks,

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.
Now I'm facing an error while starting Xamarin Android Player.
Error : OpenGL server is unreachable. Please check that Xamarin Android Player is allowed through your firewall on public networks.
I'm using Windows8.1 (64-bit).
Xamarin Android Player is allowed on public networks.
The screen shots of the errors are attached with this.
Is there any way to get rid of this error !
Screen shot 01
Screen shot 02
Screen shot 03
I got this error all the time. What fixed it for me was closing adb.exe. Go to task manager and close adb.exe before restarting Xamarin.
If that doesn't work, try to reinstall the host only network adapters in Virtualbox. Open virtualbox -> File -> preferences -> Network -> Host only. And remove all the adapters. Then restart Xamarin. It will prompt to reinstall the adapters. Click Ok.
McAfee antivirus blocks Player if you have installed, I tried to stop and now it works well.
I had this same issue in mac OS, in my case I already had virtual box with different network configurations from previous VMs that were causing this issue.
To fix this I had to set the host only network to the appropriate values.
In the VirtualBox settings of the Android Emulator VM, inside the Network Tab -> Adapter 1 verify the name of your host-only adapter (in my case vboxnet0)
With that name in mind navigate to VirtualBox VM -> Preferences -> Network -> Host-only Networks and double click the one selected in step 1.
Set the following values:
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..
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?

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.
