Managing Virtual Machines Usingthe VMware Virtual InfrastructureSDK with Dell OpenManage andAltiris Deployment SolutionDave Jaffe and Todd MuirheadMichael HopkinAltiris, Inc.
Introduction VMware is great but how do you manage allyour ESX Server hosts and virtual machines? Automated installation of ESX Server Just like you have tools to install any OS Virtual machine management Traditional management challenges (How to create virtualmachines, install OSes, apply patches) New challenges stemming from this new pool of computeresources (load balancing, failover, cloning) Answer: Virtual Center scripting thirdparty tools
Management Solutions For VMware Dell offers several approaches toVMware management Use of VMware virtual infrastructure SDK scripts,either standalone or in combination with othertools such as Dell OpenManage software Use of third party tools such as Altiris Deployment Solution for Dell Servers, which workswith the Dell Deployment Toolkit to providemanagement of virtual machines and ESX Server
Dell OpenManage: VMware Integration A technology demonstration to show howscripting can be used with managementtools to provide, in this case, afailover capability Components: IT Assistant: One-to-many mgmt console OpenManage System Administrator: Agentinstalled on server to monitor hardware Version available for ESX Server VMware Virtual Center: Manage virtual machines,run scripts using web services interface
Dell OpenManage: VMware Integration,cont. Virtual Center script: VMALL When called, moves all virtual machines offspecified ESX Server host to other hosts in farmin load-balanced fashion Called by IT Assistant when error or warning isdetected on an ESX Server host For ions/OM-VMware-Integration.pdf

VMALL Script Details Moves virtual machines sequentially from aspecified ESX Server host to the least loadedhost in ESX Server farm First need to turn on performance counters To the vmaConfig.xml configuration file add thefollowing line anywhere between the subject and /subject tags: periodicPerfRefreshEnable true /periodicPerfRefreshEnable Then restart the VMware VirtualCenter Webserviceservice from the Windows services control panel
VMALL: Perf Counter Codestring perfhandle vma .ResolvePath("/perf/0000000060");vc vma .GetContents(perfhandle);c (Container) vc.body;items c.item;for (i 0; i items.Length; i ){if (items[i].type.ToString() "PerfCollection"){vc vma .GetContents(items[i].key);stats (PerfCollection) vc.body;for (j 0; j stats.source.Length; j ){vc vma .GetContents(stats.source[j].key);if (vc.body.GetType().ToString() "VMware.vma.Host"){host (Host) vc.body;if (host.info.hostname hostname){PerfSample[] sample stats.source[j].sample;PerfStat[] sample stats sample[0].stat;
VMALL: Perf Counter Code, cont.for (int k 0; k sample stats.Length; k ){PerfStat stat sample stats[k];PerfStatType statType stat.type;if (statType PerfStatType.cpu){CPUPerf data (CPUPerf) stat.data;used string data.used.ToString();used total Convert.ToInt32(used string);} // End if (statType PerfStatType.cpu)} // End loop on k} // End if (host.info.hostname hostname)} // End if (vc.body.GetType().ToString() "VMware.vma.Host")} // End loop on j} // End if (items[i].type.ToString() "PerfCollection")} // End loop on i
VMClone Script Creates clones of a specified virtual machine withhostname, IP address and storage specified in aconfiguration 8.50.165[NewSAN1] For Windows can call Sysprep in script toautomate Windows setup of clone Uses autoprep object (see code, next slide)
