So, it should be some problem inside the changes in the 6.1.32 version, because 6.1.30 works, 6.1.32 doesn't.

Then I used the old 6.1.30 installer file (that fortunately I still had), installed it, system shutdown, re-boot, and again my virtual Windows-XP machine executes without any problem. I did a system shutdown and reboot, installed 6.1.32, again shutdown and reboot, started 6.1.32, tried to execute again the Windows XP virtual machine and same error came. Then I did a fresh download of 6.1.32 version to be sure I have a correct one and not one that could have any error. I checked again everything that the two post you refer to indicates, and everything is OK and as expected. Sorry for being late in answering, but, even I subscribed to this topic, I didn't get indication of your post. It was working yesterday, no changes in the system. I tried all the possible solutions for the problem I found, no way, it doesn't work. In the virtual machine settings-Acceleration-Hardware of Acceleration-Enable nested paging is not enabled and in grey, no way to enable it In the virtual machine settings-Acceleration-Interface: Predetermined (I tried other options, same result) VT-x/AMD-V is disabled and in grey, no way to enable it. In the virtual machine settings-processor-PAE/NX is enabled. Virtualbox is 6.1.32r149290 (just updated a couple of days ago) Virtual machine is defined with 1Gb, it is a Windows XP Pro. Hyper-V of Windows is not enabled in windows characteristics. If I ask in Windows taskmanager, it says Virtualization is Active (for the case I disabled it, reboot, then shutdown, enabled it, and reboot, no way) VT-x is disabled in the BIOS for all CPU modes (VERR_VMX_MSR_ALL_VMX_DISABLED). Not in a hypervisor partition (HVP=0) (VERR_NEM_NOT_AVAILABLE). Hi, I am running Virtualbox in a Lenovo T500 with Processor: Intel Core 2 Duo T9550 running with 64bits and 8Gb memory, today when I tried to load the virtual Windows XP Pro I have defined, I get following and well known error:įallo al abrir una sesión para la máquina virtual Windows XP Pro.

I maintain the original post in order to give them the problem information. Something to have people from support or development to think and work on it. Simply I downgraded VirtualBox to 6.1.30r148432 and problem dissapeared, SOLVED.
