Add multiple Local Storage for the XEN Server. Assume that your XEN Server has two hard disks. Sda and sdb are used as the system disk, and the default Storage of the XEN Server also uses sda. What we need to do is to load the sdb to the xen Server as Storage. Step 1: Use fdisk format sdb (you can skip this step if for

0. the net bridge works on the data link layer. Under eth0 and eth1, after receiving the data packet, the net bridge forwards the packet to one or more NICs connected to the net bridge according to the MAC address. That is to say, if the bridge is not working properly, the network will be disconnected (if there is a bridge) 1. The default bridge started in xen is xenbr0. If you want to change it to your own bridge/Etc/

Kernel-based virtual Machine is an open source system virtualization module that has been integrated into various major distributions of Linux since Linux 2.6.20. It is managed using Linux's own scheduler, so its core source code is few compared to Xen. KVM has become one of the mainstream VMM in academia today. KVM Virtualization requires hardware support (such
