In HP-UX, any LAN port with port number 900 or greater is an APA (for example, lan900 or lan901). • None This creates a local vswitch. When no physical network device on the VM Host is chosen, the vswitch is a local vswitch. A local vswitch has no connection with any physical network device on the VM Host. Virtual machine virtual network interface cards (vNICs) 88 Working with Virtual Machines can communicate only with other virtual machines on the same VM Host that are connected to the same local vswitch. 4. Specify whether or not to start the vswitch after it is created. The default is to start the vswitch. Clicking OK does the following: • Creates the new vswitch, using the hpvmnet command. • If you chose to make the vswitch dedicated, configures the vswitch as a dedicated vswitch, using the hpvmdevmgmt command. • If you chose to have the switch started, starts the vswitch, using the hpvmnet command. A preview of these commands is shown in the Command Preview area. After you click OK, any errors that occur with the execution of these commands is displayed on a separate error page that lists each command and whether the command succeeded, failed, or was not attempted. Clicking OK on the error page returns you to the Create Vswitch page. Starting, Stopping, and Deleting Virtual Switches To start or stop a virtual switch, select Tools>Start Virtual Switch... or Tools>Stop Virtual Switch... from the VM Manager menu bar. To delete a virtual switch, select Delete>Virtual Switch.... Access these menu options from a view that allows you to select one or more virtual switches, such as the VM Host Virtual Switches tab. In this way, you can act on several multiple switches simultaneously, if selected. (You can also access the menu options from the Vswitch Properties view, in which case the action is performed on a single virtual switch: the one being viewed.) To start a vswitch, select Tools>Start Virtual Switch.... Once a vswitch is started, the virtual machines that are connected to it can use it for network connectivity. Before you start a vswitch, it must be stopped. To stop a vswitch, select Tools>Stop Virtual Switch.... The selected vswitch must currently be started. Once a vswitch is stopped, the virtual machines connected to it can no longer use it for network connectivity. To remove all configuration information for a vswitch, select Delete>Virtual Switch.... Before you remove a vswitch, you must first stop it. NOTE: For information about creating and managing vswitches, see the HP Integrity Virtual Machines Installation, Configuration, and Administration manual. Deleting Network or Storage Devices To delete a network device or storage adapter, use the hpvmmodify command at the Integrity VM CLI. For example, to delete the virtual disk at hardware address 0,1,0 from the virtual machine miney01, enter the following command: # hpvmmodify -P miney01 -d disk:scsi:0,1,0 You can determine a storage device's hardware address by viewing the VM Properties Storage tab and inspecting the box that represents the storage device in the Virtual Storage column. The following figure shows a portion of the column. In this example, the address is displayed as “bus 0, dev 1, tgt 0”. Starting, Stopping, and Deleting Virtual Switches 89 The following command example shows how to delete the AVIO network device at hardware address 0,1 on virtual machine miney01 : # hpvmmodify -P miney01 -d network:avio_lan:0,1 You can determine the network device's address in a similar manner by inspecting the Virtual Network Interfaces column of the VM Properties Network tab. 90 Working with Virtual Machines A Error Messages and Troubleshooting This appendix discusses error messages and troubleshooting related to VM Manager problems, and describes the error and status labels that might appear with utilization meters (bar graphs) displayed on certain VM Manager screens. This appendix includes the following sections: • “Error Messages” (page 91) • “Utilization Meter Status/Error Information” (page 92) • “Troubleshooting Virtual Machine Problems” (page 93) Error Messages Error messages visible in VM Manager are returned primarily from the Integrity VM commands themselves. This section describes how to review such error messages as logged by Integrity VM and includes information about error messages that might be seen when attempting to access VM Manager. Other errors or problems are discussed in “Troubleshooting Virtual Machine Problems” (page 93). Reviewing Error Messages To review an error message that resulted from an Integrity VM command run by VM Manager in the past (and so is not currently viewable), you can select View>Integrity VM log for VM Host... or View>Integrity VM log for VM.... The former menu item displays events logged by Integrity VM that pertain to the VM Host and all its guests. The latter menu item displays events logged by Integrity VM that pertain to a specific virtual machine. For more information, see “Viewing Integrity VM H...
