With scores of step-by-step solutions, this cookbook helps you work with VMware ESXi in a wide range of network environments. You’ll not only learn the basics—how to pool resources from hardware servers, computer clusters, networks, and storage, and then distribute them among virtual machines—but also how to overcome the stumbling blocks you’ll encounter when you monitor systems, troubleshoot problems, and deal with security.
This expanded second edition covers recent advances in vCloud Director and vShield cloud security. Ideal for system administrators of any level, VMware Cookbook also includes valuable information to help you determine your virtualization needs.
- Move into the cloud with vCloud Director, and secure virtual datacenters with vSphere
- Secure and monitor your virtual environment from the command line
- Manage disk, SSD, and SAN storage implementation and configuration
- Discover options for managing resources, such as clustering, shares, and hot add/hotplug support
- Configure logical and physical networks, including virtual switches and software and hardware adapters
- Make virtual machine replication easier by automating ESXi installations
- Gain valuable tips for configuration and fine-tuning

VCenter server) will be disconnected. It’s important to note that in your vCenter server, the host will show as disconnected while the management network restarts; however, your virtual machines will continue to be unaffected. Reset Customized Settings Resetting the customized settings will reset all the variables on the ESXi server to factory defaults. 4. The DNS servers and hostname will need to be configured as well. Select the DNS Configuration menu as shown (Figure 1-6). Primary DNS Server.
Will assign a different number to access the storage device. The first number can also change if the card is moved to another PCI slot in the server. • The third number will change if any modifications are made to the mappings on the Fibre Channel or iSCSI targets that are visible to the ESXI server. 2.4 Creating a Network for the Software iSCSI Initiator Problem You want to create a separate iSCSI network to isolate storage traffic for servers when communicating with the storage device.
Very important when your virtual machines vMotion from server to server inside your cluster. In a traditional vSwitch configuration, you had to worry about the naming conventions of your vSwitches to ensure compatibility when doing vMotion. This is resolved when moving to a Distributed Switch, because it provides a common naming scheme across the ESXi hosts attached to the distributed switch. Like traditional vSwitches, the Distributed Switches act like a hub, providing ports for the virtual.
Example of exporting the network and storage information in Perl format as follows (we’ve truncated the output in this example to save space): ~ # esxcfg-info -s -n -F perl > test1.log $host = { { #network_info current_max_virtual_switches => 256, next_reboot_max_virtual_switches => 256, { #console_nic_info console_nics => [ ], }, { #routing_info kernel_gateway => "0.0.0.0", kernel_ipv6_gateway => "::", console_gateway => "0.0.0.0", console_gateway_device => ", console_ipv4_gateway_interface =>.
