Yes, I had the same issue with 4.3.0. Same crash. Disabling 3D acceleration prevents crash but is then slow

Oops, I attached the wrong log file. I have replaced it with the correct one now -Sorry :oops: Also adding the VBoxSVC.log here: VBoxSVC.log I don't know if the guest is crashing or the Virtual Machine hosting the guest. The crash report comes from Windows stating that "Oracle VM has stopped......

Hi,
I did a complete fresh install of Ubuntu 13.04 guest on Windows 7 64 bit.
After installing the guest additions, enabling 3D acc and after reboot, the VM crashes when I try to log in.
Attachig the VM Log
Any suggestions on how to recover?

Hello, VBox 4.3 Running on Win7/64 with Ubuntu 13.04 guest. After installing Guest additions and with 3D acceleration enabled. After booting properly to the log in screen, the screen turns black when trying to log in. It does seem like it is operational: Alt-Ctrl-T apparently brings up a terminal an...

Ok, -very good. I'll be waiting for the maintenance release then.

The log is here with (The problem present when this log was created) VBoxSVC.log.6.log But actually, after upgrading from 4.2.18 to 4.3 this time, the problem with 64 bit, acceleration and CPU:s is gone. That part is now working. When I had the problem, I first upgraded from 4.2.12 and when it did n...

I downgraded to 4.2.18 and then 64 bit operating systems are available
I noted another thing as well
In 4.3 the Acceleration tab in system settings is grayed out while it is enabled in 4.2.18

I see he did in fact post a log (just above his screenshot), however the log seems inconsistent with the report. It shows an Ubuntu 64 VM successfully using VT-x on 4.3.0. I take it this log is from a different VM. Was it on the same host? If yes then has anything happened to the host since the VM ...

I bet your real issue is that VT-x/AMD-V is disabled on your system or used by something else. Then VirtualBox does not offer 64 bit guests and doesn't allow increasing the VCPU count. If only you'd have provided VBox.log as mentioned in the Troubleshooting chapter of the manual then we could say a...

Thanks Ramshankar,

The command VBoxManage did the trick and my VM Started.
Still the CPU-Count is grayed out, i.e. no warning could be given. (Running much slower now but I'll take that in another thread)

I just upgraded to 4.3 hoping to run Ubuntu 13.04 smoothly. However, the 64 bit version of Ubuntu does no longer appear as choice when creatng a new VM. When trying to install from the ubuntu iso, I get a message that 64 bit CPU is required In addition, the number of processors is grayed out. (pre 4...
