Visualbox newspaper Vt-x is disabled in the BIOS. (verr_vmx_msr_vmxon_disabled). The reason is very simple, the process is very twists and turns

Write in front:

Coincides with the 70 anniversary of the victory of the anti-Japanese war, around the friends are taking advantage of the three-day small long vacation tourism, dashing and unrestrained, for my lonely house, holiday is the most boring thing, basically is bored lying in bed, brush micro bo, Brush Friends Circle, and then brush QQ space, look at them on the internet all kinds of drying, point , and finally brush the news, basically sent away most of the time. When there is no more to brush, then lazy to climb up, open the computer to start the code, stroll blog.

Some time ago, I recommended an Android simulator--genymotion, so I downloaded an integrated Visualbox installation package, and then use the Android Studio plug-in call, really immediately fell in love with, you can configure the emulator parameters, such as screen resolution, Memory size, number of CPUs, easy download, deployment of the latest genymotion virtual appliance, and the ability to run multiple versions of Android at the same time. In fact, it should be a virtual machine, not a simulator.

Problems and Solutions:

Because of personal idle egg pain, yesterday in Visualbox configured a CentOS server, everything is very smooth, look at the time is more than 1 o'clock late at night, so do not give up the computer to go to bed to sleep. However, the problem immediately came to the door, because the customer about the evening to talk about the project needs, so the morning to get ready to look at the Android, when I opened as call Genymotion, but how can not open, has been prompted genymotion virtual device failed to start:

Look at the hint is visualbox can not start, so the direct manual start Visualbox, directly in the Visualbox launch Android virtual machine, sure enough to start:

The problem comes again, my Computer BIOS Intel virtualization is open, is it yesterday installed CentOS changed the BIOS? (although this is unlikely), or restart the computer into the BIOS to see a bit, is the state of the open, in case I first banned and then enabled, and then F10 save restart. But it's no use for eggs. So search on the Internet, this problem seems to be a lot of people have appeared, online a lot, according to the online statement tried a few:

According to this netizen's saying I checked the next own virtual machine configuration, already is VirtualBox host-only Ethernet adapter, does not apply my situation.

According to this netizen, I uninstalled genymotion and Visualbox reinstall and reconfigure, try not to, and then uninstall and the registry C disk residue files and other related to delete, the problem remains.

Read this Netizen's statement, gave me the revelation, I went into the visualbox to check the hardware acceleration options in the settings, sure enough this option is not selected and not editable, but the above this netizen is editable. The problem is definitely here, because the vt-x in my hardware acceleration option doesn't start properly, so it won't start. Finally on a foreigner's website to see a more comprehensive analysis:

According to him, my computer is really a i3 processor, and the system is 64-bit, his description exactly match, so began to check the program log, it is true. So what is the cause of this? I used it well before, how come suddenly? Eventually found the root cause of the problem, very brain-crippled, but also very silent. It's my outfit. 360 Make a ghost, 360 have a nuclear crystal protection function, when the program needs to run the virtualization technology, it for the stability of the hardware will temporarily shut down the technology, it must not be able to run, then decisively quit 360, again configured, OK success! (Egg hurts!) ）。 Set the next 360, and then create a new test as project, but also happy to play!

Conclusion:

Look at the time, it's 1:30 P.M., and the holidays are halfway through. I level limited, write down just a little summary of their own learning process, but also to share entertainment and entertainment, welcome to shoot Bricks ~ ~
