Phone flashes KVM hardware virtualization 10

Hello, the official website does not provide flashing software. Due to the risks associated with flashing, such as mobile phone problems caused by self-flashing, it may also affect the repair, so we do not recommend that you flash your phone by yourself.

If the mobile phone cannot be used normally due to system failure or causes problems with the mobile phone after flashing the phone by itself, it is recommended that you send the machine to the after-sales service center for the help of the engineer to check and deal with it. "

I'm also shopping for this thing.,Recently win10 arm64 came out.,It just so happens that my phone is also aarch64 architecture.,I want to kvm a win10 on the phone.,There is no simple solution to open kvm on the phone.,I haven't succeeded.,But I've collected some solutions.,It's good to toss around.。

First of all, you have to know whether the chip of your mobile phone supports virtualization,32-bit ARM doesn't have to think about it,It's useless to turn it on (armv7 armhf),MediaTek and Hayes don't have to think about most of them don't support,Snapdragon 6xx or more can try,Broadcom and the like have to go to the official website to see the documentation,If you can't find it, look below。

Go to github or the official website of the mobile phone to find the source code of your mobile phone kernel, for example, I am Xiaomi, it is easy to search on github, like Huawei, you don't have to think about it, they hide the kernel that should be open source tightly.

Then you need an x86 64 Linux computer, it is recommended to have a physical machine, put the kernel ** to this computer, install the corresponding cross-compilation tool, use apt to search for two of the three keywords arm gcc gun, and you may need other things, look at the documentation given by the kernel, which will generally prompt you to lack something.

Next, the same as compiling the Linux kernel,Compiling with make will prompt you to set some support class things,For example, disk format support and the like,Most of the defaults are OK,It's best to go through one line at a time,And then see if there is an option for kvm,If there is, choose yes,If not, the phone is estimated not to support,Flash the compiled kernel to the phone with adb or fastboot,It's generally good after restarting。

It's really dangerous to do this, be cautious, if you have poor hands-on ability, forget it, not only easy to break but also easy to pigeon cooing, it's better not to waste time, **buy a raspberry pie or latte panda, isn't it better, no money? Anything in the dream!!

Declared a failure,Even if you brush into the kvm kernel,The boot of the Android phone is still turned off by defaultKVM,If you want to open the firmware leakage of this mobile phone, you need to modify the compilation boot again,This will be a very complicated process,And the firmware leak excludes most of the mobile phones,At present, XDA has also encountered Xiaomi Mi6 and Mi 8 were guided by the Russians,These projects are still cracking,Wash and sleep。

KVM virtualization technology consists of several parts, KVM core module (CPU and memory virtualization and management), KVM other hardware device simulation. Among the other hardware devices, the more important ones are disk and network devices, and this part of the virtualization is done by using QEMU, which is called modified QEMU, that is, QEMU-KVM. Of course, QEMU technology is used, so its management and use of disks is done by QEMU-IMG.

Kernel-based Virtual Machine, short for Kernel-Based Virtual Machine, is an open-source system virtualization module that has been integrated into major Linux distributions since Linux. It is managed using Linux's own scheduler, so it has very little core source code compared to Xen. KVM has become one of the mainstream VMMs in academia.

Virtualization of the KVM requires hardware support (e.g. Intel VT technology or AMD V technology). It is fully virtualized hardware-based. In the early days, Xen was based on para-virtualization based on software emulation, and the new version is based on full virtualization supported by hardware.

However, xen itself has its own process scheduler, storage management module, etc., so it is relatively large. The VMware ESX series, the widely circulated business system virtualization software, is also based on software simulation.

This still needs to be taught, and it will be used as soon as it is used.

This means that the new QEMU version does not support some CPU flags for the host system.

You can change the CPU type of the VM to a more conservative "KVM64" type and see if it solves your problem.

Disk and network device virtualization.

Do you want to have one CPU 1 core and virtual multiple cores?

KVM isn't very clear, VMware ESXi may not be able to do it. However, with the hyper-threading of the term, the difference between creating a new virtual machine with one CPU and using multiple virtual machines is only the processing speed of the CPU.

KVM is specially used for the same screen, and now Jiamei Xun has the same screen software technology in software mode, and this kind of screen sharing software is based on the virtualization software developed by KVM.
