system, installed on bare metal (server, desktop, etc.), can also be installed in the VMware Workstation's. VCenter Server 5.5 centralizes all ESXI5.5 and gives it to VMware VSphere 5.5. VMware VSphere 5.5 is used to manage all of the servers submitted by Vcenter Server 5.5 and provides a centralized configuration management interface that can be used to implement vmotion (online migration), DRS (distributed resource Scheduling), HA (high availability), and FT (fault tolerance) capabilities.

Three versions of VMwareWorkstation: Single level, used in personal desktop system, requires operating system supportServier: Workgroup level, for server, requires operating system supportESXi: Enterprise level, for servers, no operating system support requiredWorkstation, Server: An application on Windows or Linux that must have a host operating system installed to install Workstaion or server before the virtual machine can be installedESXi: is a standalone virtual machine that can be installed
Simply record the first of the virtual machine.
1. viclient Login to Vcenter or ESXi, add a disk to the virtual machine
Add disks to the virtual machine online.
2. Log into the virtual machine Linux system execute the following command to identify the newly added hard drive
echo "--" >/sys/class/scsi_host/host0/scan
3. The following is the partition, add LVM volume.
No downtime is required for the entire process system application.

One or more of the three virtual machines will be migrated to other idle hosts.B. Suppose we set these three VMS to a test group and run the loop script bat in the VM, 3 Virtual opportunities are migrated to a host with a large amount of idle resources (including the local machine. This method applies when there is a Dongle)C. Suppose we s

Recently I changed my work. During work handover, I found that many esxi hosts do not have a password and all of them can only be cracked.
To restore the password, perform the following operations:
Use Linux to start a CD, such as an rhel5 installation CD or knoppix.
Create the/mnt/sda5 directory, mkdir/mnt/sda5
Mount command:
Mount-tvfat Mount/dev/sda5/mnt/sda5
