Install and configure Xen on Ubuntu

The server hard disk has been upgraded and the memory is still waiting. The memory is ordered with the hard disk. I don't know why it hasn't arrived yet. I finally found out why the RAID0 test result was abnormal the day before yesterday, A hard disk is faulty ~ There is a problem with the newly purchased unpacked hard disk. Currently, most SUN servers only have 2 GB-8 GB of memory. After the upgrade, the memory size should be 8 GB-32 GB, so that more memory can be allocated to each Xen virtual machine. Some of our operating systems are still 32-bit and must be upgraded to 64-bit to cope with the arrival of large memory. Today
