the VMM for processing, and in this design concept, modifying the guest OS kernel.The ability to modify the guest OS is a technical core of para-virtualization. By modifying the kernel of the guest OS. Making the guest OS clearly aware that it is running on the 1 ring, rather than the 0 loop of the usual OS, effectively avoids the problem of virtualized execution conflicts. The Guest OS also knows that VMM provides itself with a virtual register grou

Environment: Virtual Server: CentOS 1, 5.4 192.168.10.6 VM: CentOS5.4 192.168.10.8 The Virtual Server XEN is installed using yum, and the virtual host is installed using virt-install. Steps: 1. To facilitate the operation, replace the default yum source of the system with the source of HKUST, which is faster in China.
