To add a new system call to a Linux system, three steps are required:1. register a new system call number2. Update the system call table3. Add a new functionAdding a hypercall to xen is similar to adding a system call to Linux. The preceding steps are basically the same. Here is a specific example:For example, we want to add a hypercall for printing a message to xen. The parameter has a type of char *, whic

The Xen virtual opportunity defaults to bind the network adapter to the XENBR0,So if you need to switch to a different physical NIC, you need to configure the script or execute the command yourself.1.

When Xen is testing or tuning, you need to perform a lower level of detail analysis (such as the frequency of statistics vmexit, the type of vmexit, how much CPU time is consumed by vmexit), and then you can use the Xentrace tool.Xentrace is a tool that comes with the Xen source code and is generated by default when make Tools is compiled. Xentrace generated data is a binary format, the human eye can not di

Early Xen used the "ring" to exchange Io between guest and driver domain, because of the design constraints, the maximum IO for one processing was 1408K, so it became a performance bottleneck when dealing with large IO. In order to solve this problem, the Xen community has put forward the concept of indirect descriptors by reference to the realization of virtio. The following references and translations fro
