xen monitoring

When using Xen virtual machines, we typically expose the virtual machine (DOMU) directly to the network in a bridging (bridging) way, just like a single server on the network, which is easy to use without any port forwarding in DOM0 without any iptable rules. However, in addition to bridging, Xen also supports the routing and NAT configuration of virtual machine networks. For example, we want to install 5 v

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
