• Get the number of virtual machines per ESX host

  I am able to get the account with the following script command, but what I want to do is to report a 0 if there is no virtual machines on a host.  Currently it just show nothing if there are no VMs.  Any suggestions?

  Get-VMHost | Sort - the name of the property. Select Name, @{N = "VMCount"; E={($_ | Get - VM). County}}

  You can add an IF in the part of the expression.

  Try it like this

  Get-VMHost | Sort-Object Name | Select Name,@{N="VM";E={if(($_ | Get-VM).Count){($_ | Get-VM).Count} else {0}}}

• Script to count total amount of memory allocated to the VM on each ESX host

  Hello

  I'm looking for a script to add all the RAM allocated to virtual machines per ESX host in vCenter.

  I can quite easily show the MemoryUsageMB and the MemoryTotalMB, but I would like to get the total amount of memory assigned to VM-based host?

  Any help would be appreciated.

  Thank you

• help - vm to 100% with Betclic resources cpu, but the ESX host to 15% cpu

  Hi all

  5 * HP BL460c Blade each with two Quad Core Xeon E5450 and and 8 GB of RAM.

  ESX 3.5

  VirtualCenter 2.5.0

  DRM and active HA.

  I need assistance with resource pools. Currently I have them all together for:

  • expandable

  • unlimited

  for the CPU and memory. I tried without reserve and with reservations, and it is indifferent to the result.

  I'm running a server SQL2008 (2 * vCPU, 3.5 GB of RAM) which is pretty hard. and from time to time the cpu usage spikes to 100% (6 GHz) and saturate at this time here. When I go to the graphs of the ESX host, I see up to 3 physical processes responsible... and all the others are dormant...

  I'm working on why he no longer not affected resources of the ESX host. I thought that because of the resource sharing (unlimited), he could catch resource from the pool of resources of the parent (unlimited). And our Installer is very very little used - so much processing power/mem available spare parts.

  I have also some really stupid questions:

  • with SMP, 1 vCPU means only 1 pCPU host is used?
    I never thought that this true, but in this example, it seems that only 2 pCPUs on the host are used... maybe 3,.., it is difficult to tell from the graph

  • a virtual machine can use more resources from a host at the same time?

  with SMP, 1 vCPU means only 1 pCPU host is used?

  I never thought that this true, but in this example, it seems that only 2 pCPUs on the host are used... maybe 3,.., it is difficult to tell from the graph

  Yes, assign you a resource equivalent to a virtual machine to the host.  Therefore, if you assign 1 vCPU which is equivalent to a unique Jepp on the host computer in the slot.

  a virtual machine can use more resources from a host at the same time?

  No. a resource pool is on a cluster, but VM inside this POOL can only use a single host resources.  The case is from ESX can use DRS to load balancing force of the VM, the pool determines the overall consumption and that you assign VM accordingly.  But ESX is not yet there to physical resource take other hosts.  What ever host is on, it is that the only place these resources can be achieved.

  What process the SQL 2008 taking up the CPU process?  I think it's SQL Server, in which case it is not that you can do.  One of the reasons that I discourage using VM for SQL, SQL works not virtualized.

• Is it possible to add an ESX host less CPU

  Hello

  Currently in my farm, I have four Dell R900 ESX host. They have (4) Quad Core Procs and 128 GB of memory. Can I add an additional R900 server that does that (2) Quad Core Procs? I will strengthen the memory based on the existing, but processors are simply too expensive. HA and DRS will manage the differences in the number of procs?

  It is a statement of official support for the use of the CPUID of the forest SSSE3 mask.  Setting this bit can hide the SSSE3 instructions, allowing you to vmotion vm from a server on the 'A' list to a list of 'B', but is not supported by VMware.  While masking is generally safe, the process only "occult" bits for applications that use the CPUID instruction to generate a list of features that a processor is capable of.  If an application does not CPUID use to verify functionality and use them in any case, then you have a problem, that's why this mask is not supported.  Hope that makes sense.

• A server Vcenter 4.1.0 coexist with 5.1.1 ESX hosts

  Hello

  I was planning on upgrading my VMware environment, but I just noticed that my vcenter server running 4.1.0 is enough CPU to run 5.1.

  Is it still possible to upgrade my hosts to 5.1.1 so that I can use the latest etc. operating systems or this will cause my unstable environment.

  any advice is greatly appericated.

  Thank you

  vCenter 4.1 can not handle 5.1 ESX hosts.

  First vCenter Server must be upgraded to 5.1 and then upgrade hosts to 5.1. So that vCenter can manage the hosts in full transparency.

• Logical processors against vCPUs per ESXi host

  Hello

  I am watching the host ESXi Configuration of maximum and to matters that I don't know what's the distinction between the logical processors for each ESXi host (160) and vCPUs per ESXi host (2048). Any explanation is greatly appreciated. Thank you!

  Hmm...

  OK I'll try to explain.

  1LCPU can be pinned to several virtual machines.

  If I have 1 quad core CPU, I have 4 LCPUs

  I can create as many virtual machines

  (1) 1 VM with vcpus 1

  (2) 1 VM with 2 vcpus

  (3) 1 VM with 4 vcpus

  1st VM will be pinned to 1 LCPU.

  2nd VM will be pinned on the 2nd, 3rd LCPU.

  3rd VM will be pinned to LCPU 1,2,3,4.

  If the processor reqquest comes from 1 VM and VM 3rd at the same time, she will be the process queue and do accordingly!

  I hope you have it now!

• How to get the loan from CPU percentage?

  Hi people,

  When I read this blog of Mr. Epping http://www.yellow-bricks.com/ESXTOP/ it seems that CPU ready is indicated as a percentage %, while in the vsphere Performace console | The Advanced tab, it shows you only in milliseconds per 20 seconds.

  If someone here can help me in the creation or modification of the script (created by Luc D) to calculate the loan of CPU percentage?

  $metrics = "cpu.usage.average", "cpu.ready.summation", "cpu.swapwait.summation", "mem.active.average".
  $entities = get-VM-name
  $start = (get-Date). AddDays(-5)
  $report = get-Stat-entity $entities - Stat $metrics - Realtime-start $start |
  Group-object - property EntityId, Timestamp | %{
  New-object PSObject-property @ {}
  Name = $_. Group [0]. @entity.name
  Time = $_. Group [0]. Timestamp
  CpuAvg = ($_.) Group | where {$_.} MetricId - eq "cpu.usage.average"}). Value
  CpuRdy = ($_.) Group | where {$_.} MetricId - eq "cpu.ready.summation" - and $_. ({Instance - eq ' '}). Value
  CpuSwpWait = ($_.) Group | where {$_.} MetricId - eq "cpu.swapwait.summation" - and $_. ({Instance - eq ' '}). Value

  }
  }
  $report | Sort-Object Name, time | Export-Csv "C:\VMstats.csv" - NoTypeInformation - UseCulture

  Any kind of help would be greatly appreciated.

  Thank you.

  It depends on the interval you are looking at.

  The 20000 is valid if you get real-time statistics, where the length of the interval is 20 seconds.

  In the example above, the script gets its Historical interval 1stats, which has a range of 300 seconds.

  That's what I do with $_. Interval * 1000 which is 300 * 1000 = 300000

• Add production ESX hosts to a cluster

  Hi all

  I did some research in the admin guides and community forums, and I'm sure that I know what to do, but I would really appreciate a test of consistency here because the manipulation I do is in a production environment:

  I have a campus that contains two ESX areas that are managed by using vSphere and connected to a San. vMotion of works very well, the performance is very good (although the resources of the two boxes are fairly complete upward). However, I recently realized that I'd neglected to set up a cluster HA and DRS.  I want to remedy.

  I created the cluster with these specs:

  • the two HA and DRS, enabled
  • to the left, she also fully automated.
  • the power management of left
  • monitoring and host admission control enabled
  • leave the default settings for the behavior of the virtual machine
  • monitoring VM disabled
  • EVC enabled
  • the storage value of the swap with the virtual machine file

  I think that the next steps would be to add each ESX host consecutively and merged its resources with the cluster. However, here are a few questions:

  • How do you assess the risk factor to do this in a production environment (1 = perfectly safe, is a proven Scenario; 5 = you are out of your bloody mind? Do not)
  • Should I be triple-checking the SAN snapshots and planning of downtime for servers, or is it possible live and without any major qualms?
  • Am I right in assuming that it will increase my performance as well as provide better robustness of the campus, or should I expect a decrease in performance?

  Thank you very much in advance for your advice!

  Hey red,

  Addressing your particular situation, I would say yes to two questions.  Admission control HA is here to help you.  Ensure there are enough resources on the host computer to run the current and any expected load it will be after an HA event.  50% is close to default (but it is really based on the size of the slot) in an environment with two guests when guest cluster failures tolerates is set to 1 in a two and 25% host environment when the percentage of unused reserved as production capacity cluster resources in failover is left to its default value.

  If you have several virtual machines running that allows you to book 50% of your cluster resources (which it sounds like you have), then you have the option of "first category" your virtual machines and their giving priorities to restart event HA.  For their level, you'll want to active DRS (can be set to manual Automation), resource pools and you will need to configure your virtual machine under your HA settings options.  You'll want to pay attention to the priority of restarting VM here.

  I suggest you take a look at blog Duncan Epping http://www.yellow-bricks.com/ and Frank Denneman http://frankdenneman.nl/blog. They are all two fairly well the definitive answer to the HA and DRS questions and advice.

  See you soon,.

  Note: Epping and Denneman explained that the amount reserved by default resources when you use the host cluster failures tolerates is promising to reserve enough resources to power on virtual machines.  This reserve of resource does not on average current, account, or future default load.  If you want to manipulate this feature, modify the memory and CPU reserves, which are the numbers used to calculate the size of the slot.

• How a VMGuest can see a number of physical ESX host processor

  Hello

  Not sure if this is expected behavior or not, but I have some application that runs from a linux machine to vmguest in my cluster Vsphere 4.0 U1 that is able to see the number of sockets processor busy on the ESX host that it is currently at. I never saw that happen up to now on another system in our environment. On Linux operating plan, when you run the "cpuinfo", the show only reviews the number of virtual processors assigned to it. I don't know how this program is able to see all the way down beyond the virtualization layer to the actual physical hardware layer on the esx host.

  My first thought was that this was triggered after the installation of the VM Tools on the guest operating system, but even after turning off the service tools you can still see the real taken account on the host computer.

  Can someone explain to me how this is possible?

  Thanks for any info you can provide

  Regardless of the tool that allows you to watch the CPU I have a strong suspicion about what is happening here.
  The exact CPU type in/proc/cpuinfo is listed: "AMD Opteron Processor 6164 HE.
  I guess that the tool you are using has some knowledge (using an internal list of program or by retrieving this information somewhere on the internet) that this CPU has really 12 hearts and he only relies on it and reported that the machine has 12 cores, instead of looking at what is really reported by the operating system.
  So, he just does not have the right to work and is not aware of virtualization.
  In any case, it is not really able to look directly into the hypervisor.

• How to test an ESX host

  What are the options for testing performance on ESX hosts?  Are there models of good OVF or vApps for ESX hosts test to determine their ability to stress?  For example, you want to determine how many virtual machines can run safely on a physical machine - is there an OVF template that will peg the CPU, memory usage usage and access hard drive at startup that you run a bunch of one host and one model OVF who will report on the usage statistics?

  Are there other (free) ways to stress tests of your physical servers?

• Open a virtual machine in a san on 2 different esx hosts

  Hi, I have a Vsphere essentials, 2 Esx hosts and an Iscsi san, I need to connect the virtual machine in the two esx hosts (I know I don't have FT and HA), in order to launch the virtual machine never the first Esx and if first host, does not have the virtual machine on the second esx.

  I tryied to connect the virtual machine to the second host, but the Vsphere client tell me that's not possible, because the virtual machine is already present at the first ESX.

  There is a way to establish this setting?

  For some it may depend on your application, if you can run multiple instances of the same application? If it is a web application? It stores its data in files on the server, or it stores it in a database locally? or remote database?

  -VM on a local storage of the army, would not really recommended if you need so that it starts the VMS on host b quickly.

  -If the two hosts have access to permits it storage even say and what the application can really be run only once.  He could only save it to HostA and if it fails at some point that it will be released the lock, have it on the virtual machine and you will be able to manually register the virtual machine to host b and start the virtual machine.  However, you will not be able to really get ahead.

  -HA out of here, as if a host or power failure shuts on HostA, HostB will feed into the virtual machine down automatically

  -FT - here in the spectrum creates a VM ghost on the secondary host in levels (what happends on HostA happens on host b)

  -Another option to the other end of things has implemented Microsoft MSCS Clustering with iSCSI support I think.  You can run VMS with iSCSI to your San and clustered like this application.  Just note that with iscsi client it uses some CPU to create iscsi packets.

  -Web Cluster, Cluster database.    It doesn't matter if one of the nodes of web servers or the database nodes go down really that the user will be redirected to another node in the cluster so really no need for HA/FT.

  Of course, with some of the here above are expenses and pro / con of and there's a few ways to increase availability.
