Hello, when I try to set my mahicnes to full screen I always receive a message like that:
"La instrucción en 0x00000000 hace referencia ala memoria en 0x00000000. La memoria no se pudo written."
I use virtualbox 5.0.38
Why can't I ?????
Thank you

Please provide a VM log file. With the VM fully shut down, right click it in GUI. Select "Show Log" and save "VBox.log" (ONLY) to a zip file. Attach the zip here.

here it is.
I tell you how I generated it.
1 - I start the VM normally.
2 - When it has started I try to go to full screen... and de message appears... and the VM goes to state "Aborted"
3 - I start again normally. (You told me to get the machine off)
4 - I turn off the VM
5 - I get the vm.log
Thanks.

Topic moved to "Windows Hosts".
Something peculiar is happening here.
00:00:00.988489 SUP: Loaded VMMR0.r0 (C:\Program Files\Oracle\VirtualBox\VMMR0.r0) at 0xXXXXXXXXXXXXXXXX - ModuleInit at XXXXXXXXXXXXXXXX and ModuleTerm at XXXXXXXXXXXXXXXX using the native ring-0 loader
00:00:00.988502 SUP: VMMR0EntryEx located at XXXXXXXXXXXXXXXX and VMMR0EntryFast at XXXXXXXXXXXXXXXX
00:00:00.988504 SUP: windbg> .reload /f C:\Program Files\Oracle\VirtualBox\VMMR0.r0=0xXXXXXXXXXXXXXXXX
What are these? Where are the memory addresses normally found in those fields?
00:00:00.999270 File system of 'I:\Software\Desarrollo\vs2015.1.com_esn.iso' (DVD) is ntfs
00:00:01.000579 File system of 'E:\Virtual\VirtualBox VMs\W764_VS_202\Snapshots' (snapshots) is unknown
00:00:01.000584 File system of 'E:\Virtual\VirtualBox VMs\W764_VS_202\W764_Base clonar-disk1.vdi' is ntfs
Strange paths.
00:00:01.403393 Display::handleDisplayResize: uScreenId=0 pvVRAM=0000000000000000 w=720 h=400 bpp=0 cbLine=0x0 flags=0x0
Again with the strange memory addresses.
Have you missed out any part of your story? Are you using a completely standard install from the offical distribution of VirtualBox?
If so I suggest that you download a more recent version (e.g. 5.1.22) and try with that.

Don,
I have been seeing those weird addresses for some time now. I suspect it is fault diagnostic code in the 5.1.* version that has not been fixed yet, but that is just a guess at this point. Do you not see this in your own guests?

The OPs log is from 5.0.38, hence my suggestion that he try something recent.

I honestly don't remember when I first saw this but 4.0.38 is still getting some updates with regards to 5.1.* work which includes some of the new diagnostic code. If I find the time ( and remember ) Monday I may ask the DEVs what is going on with this.

More information could be that I updated to 5.1 versión however VMs didn't start, I can't remember because of... so I "downgraded" again to 4.0... however I could tell you if the problem was before or after....

Another fact to point out could be that some machines where cloned from others created before...
Anothers created in differents folders...
But, even if I créate a new one... the problem comes as far as I try to set it to full screen. I don`t try full screen everything goes perfectly.
Thanks.

As mentioned, try updating to a current version of VirtualBox. Update the Guest Additions at the same time.
Speaking of the Guest Additions, I see no evidence that they have been installed in this VM, and fullscreen mode certainly won't work without them - though I would not have expected a crash.

If I go to the last versión... I mean 5.1 --> VMs don't start .... I keep 5.0 because of that...
I run 5.0.40, I have tried to installa guest additions in one of my VMs... and I have the same problema with full screen

I stumbled in the answer. From ticket
#15167: Kernel Address Info Leak, you can see what's going on in
CVE-2017-3513:
Vulnerability in the Oracle VM VirtualBox component of Oracle Virtualization (subcomponent: Core). Supported versions that are affected are Prior to 5.0.38 and Prior to 5.1.20. Difficult to exploit vulnerability ...
Bottom line, you're going to be seeing a lot of XXXXX addresses from now on...
