Wherein, the configuration instruction includes a new processor characteristic configuration file, namely a modified processor characteristic configuration file.
It should be noted that, after purchasing the cloud host, the user may modify the configuration file of the processor characteristics according to the configuration specification (i.e., the product specification or some operation instruction, etc.) of the cloud host to form a new configuration file of the processor characteristics.
As a possible implementation manner, after modifying the configuration file, the user may upload the new processor characteristic configuration file to the cloud host management platform, and then the cloud host management platform may send the new processor characteristic configuration file to the cloud host.
As another possible implementation manner, in order to meet different requirements of different users, some modified processor characteristic profiles (or templates that can be understood as some processor characteristic profiles are stored in advance) may be stored in advance on the cloud host management platform, and a user may directly select a new processor characteristic profile without separately writing the profile.

1. and the cloud host management platform sends the configuration file to the cloud host.
2. And the cloud host judges whether the configuration parameters in the configuration file are first parameters, if so, the step 3 is continuously executed, and if so, the step 4 is executed.
Wherein the first parameter is host, and the second parameter is custom.
In some embodiments, the cloud host may call the Set _ mode () interface of Libvirt to obtain parameter information in the configuration file features. And if the parameter is host, executing the step 3, and if the parameter is custom, executing the step 4 and the following steps.

The Default value can be understood as a Default characteristic used when the cloud host is started. I.e. new processor characteristics information is entered in the Custom Features.
6. QEMU calls ioctl interface, and assigns modified Custom Features to Emulated Features.
In the embodiment of the application, the ioctl interface is modified, so that the processor characteristic information of the cloud host can be modified and adjusted online. That is to say, the ioctl interface in the embodiment of the present application may be used to modify processor characteristic information of the cloud host.
