ESX and VMware scripting Backend process...

Hi all

I look forward to hearing the internal processes that continue on the street within the ESX Server. For example:-that the ESX actually did when the user fires rescan command esxcfg-rescan & lt; vmhba. & gt;. Is there any script is triggered on commanded this shooting? and even on the backend to another ESX processes orders too. I want to update my self on these things. Hope someone here could give me a helping hand.

Concerning

MRM

If you are interested about how ESX (i) and some of the inner workings, you should take a look at some of the documents/charts architecture, this is available on VMworld if you have an account, and the majority of it should be free of previous years, less the recent VMworld Europe / U.S..

Here is another good site for a collection of documents to help: http://vsphere-land.com/top-10-list/top-10-list-index.html

If you are only interested in some of the esxcfg-* commands, a good way to learn what it is doing and the parts of the system it touches is to download the vCLI/RCLI: http://engineering.ucsb.edu/~duonglt/vmware/#vmware_rcli

These commands are similar to that of those on the classic ESX which are used to manage/configure remote both ESX(I) hosts and they use the VI API http://www.vmware.com/support/developer/vc-sdk/visdk25pubs/ReferenceGuide/index.html

You can open each of these scripts and get a good understanding, most of the classic esxcfg-* commands are compiled binaries which makes internal calls to the system, but some are normal Perl/bash scripts such as esxcfg-rescan or vmware-cmd and you can open these and take a look at what he does.

So it really depends on what you're trying to understand and explain how you want to enter.

I hope that gives you an idea of where to go.

  • New to 5 of ESX and VMWare

    Stupid question, I just installed ESX5 and it keeps warning me that require a license.  I got the license for 60 days when I signed and downloaded the software but there is no place to enter!  I use the Client software and try to create a new machine, whenever I start the machine, it disconnects the ISO I want to use to install an operating system.

    1. where can I enter the license number and

    2 How to install a new OS in a new virtual machine if she keeps disconnect the ISO as soon as I start the new virtual machine?

    Any help would be appreciated.

    Thank you

    Hello and welcome to the forums!

    1. you must enter the license key in the vSphere Client: in the 'Configuration' tab, click on "Software/Licensed features" on the left, click the 'change... '. "link at the top to right.

    2. If you want to connect to a CD-ROM / ISO type 'Client' while this is possible when the machine is under voltage. Then, turn on the virtual machine first, then use the menu in the console for you connect to a local ISO file or a local CD-ROM drive. If the Starter goes too fast, restart again by pressing Ctrl-Alt-INS to the console.

    I suspect that you posted your question to the wrong thread

    This requires only a minor change to the script above actually.

    Something like that

    $groupName = "group"$accountName = "user"$accountPswd = "password"$accountDescription = "A user"
    
    $esxlist = Get-VMHostforeach($esx in $esxlist){    Connect-VIServer -Server $esx -User root -Password "password"
    
        Try {      Get-VMHostAccount -Id $groupName -Group -ErrorAction Stop | Out-Null    }    Catch {      New-VMHostAccount -Id $groupName -GroupAccount | Out-Null    }

  • Script - missing and hotfixes installed for ESX and ESXi

    Can I have the script i.e. missing and hotfixes installed for ESX and ESXi using the CLI power only? out put should be csv format

    You reset the content of the table $Results on each iteration of the baseline.

    Try like this

    $Results = @()
    foreach($esx in Get-VMHost) {
      foreach($baseline in (Get-Compliance -Entity $esx -Detailed | where {$_.Status -eq "NotCompliant"})){
        $Results += $baseline.CompliantPatches |    Select @{N="Host";E={$esx.Name}},    @{N="Status";E={"Compliant"}},    @{N="Baseline";E={$baseline.Baseline.Name}},Name,ReleaseDate,IdByVendor,    @{N="KB";E={(Select-String "(?http://[\w|\.|/]*\w{1})" -InputObject $_.Description).Matches[0].Groups['url'].Value}}
    
        $Results += $baseline.NotCompliantPatches |    Select @{N="Host";E={$esx.Name}},    @{N="Status";E={"NotCompliant"}},    @{N="Baseline";E={$baseline.Baseline.Name}},Name,ReleaseDate,IdByVendor,    @{N="KB";E={(Select-String "(?http://[\w|\.|/]*\w{1})" -InputObject $_.Description).Matches[0].Groups['url'].Value}}
      }
    }
    $Results
    

    It will give the installed and lack of patches which are defined in the non-compliant baslines related to the ESXi host.

    If you want to see all the lines, also the most consistent, omit the Where clause on the base line (foreach) loop.

  • Stop the Service Console and shell scripts

    Now that VMware announced ESX 4.1 is their last hypervisor with a service console, I was wondering-

    What are the options to make what is now a large number of Linux shell scripts perform the same functions on ESXi - i.e. PowerCLI, Host Profiles, etc. and how long we have until officially support chips for the ESX service console?

    Thank you

    PowerCLI does not rely on a service console. However, you must have paid the ESXi version for them to work.  With respect to the profiles of the host, which is a characteristic of vCenter and has more no dependencies on the COS.  You can start watching to convert all of your shell scripts PowerCLI and use scripts.

    What about when VMware will stop support for ESX, I do not anticipate happening any time soon.

  • Question: ESX and vShield

    Hello

    I am conducting a study on the safety in the vrtual environment and I have a question about VMWare Hypervisors.

    ESX and adjustable vShield upward on the same server cluster? They both will remain as hypervisors? because from what I've read, I've heard that ESX and vShield are hypervisors and vShield is only for reasons of security, while ESX is a more general hypervisor...

    Could you confirm or explain my mistakes?

    Thank you

    ESXi is the hypervisor - taking the material resources of a host and delivering them to virtual machines. vShield provides a layer of security to the virtual environment using virtual machines / devices that run on the computer host ESXi - hope this clears up it

  • ESX and ESXi

    What are the fundamental differences between ESX and ESXi. Someone could it say please interview point of view. Just need about 4 to 5 differences.

    Thank you

    Prashant

    The difference between ESX and ESXi, ESX was the classic version with a dedicated Service console embarked with him, however, ESXi is the version of Vsphere without the Console service. Because ESXi is without the service console, so its size is very small and its called summer have footprint small disc. With the release of VSphere VMware 5.0 and later versions has deprecated the classic ESX version there is therefore no now unavailable ESX and we only ESXi now.

  • Differences between ESX and ESXi

    Hai,

    As I am new to VI environment I doubt that where features ESX and ESXi are different, it may be stupid but can help me a lot.

    Hello

    Please check the link to the differences between ESX and ESXi below.

    http://www.VMware.com/products/vSphere/ESXi-and-ESX/compare.html

    Please note ESX is present in version 3.x, 4.x. starting vsphere 5.0, we have only ESXi.

    ESXi doesnot have a service console and has the smallest footprint of 70 MB and so is safer and more reliable, because it has a smaller surface set.

    Please allow points if you find the article useful.

  • VMotion with ESX and ESXi in the same cluster.

    My client wants to spend his whole army ESX 4.0 to ESXi 4.1 host. I know that it requires a clean install of the host. But vMotion always works in a cluster with a mix of the host ESX 4.0 and ESXi 4.1?

    You will be fine to have a mixed group of ESX and ESXi hosts.

  • Server 2008 and VMware issues

    I just heard a rumor that there may be some

    problems with Microsoft Server 2008 and VMware version 4.0.   We are in

    If there is a problem.

    in fact, there is a problem (again), involving most of the time the upgrade of virtual hardware version 4 virtual hardware version 7, and she is related to the way Windows 2008 handles the mounting of 2 or several disks (standard windows 2008 t - it a way, Windows 2008 Enterprise made the opposite effect)

  • Licenses of Microsoft and VMware data center

    Hello

    You have a question regarding Microsoft Licensing and VMware ESX hosts.

    We have a Microsoft School Agreement and a lot of our windows servers are running standard edition. One is business running. All about the physical servers.

    We are virtualizing some of our Windows servers and schools prices are very favourable if we buy a license of data center. Its about £70 and it means that we can run an unlimited number of Microsoft server VM in VMware. relation to the enterprise which is only £5 cheaper, but only allows you to run a maximum of 4 people.

    Question, I realized that a Windows license for data center would be per processor, so if I have 2 physical processorsin each esx host, I need to get 2 X Datacenter license per ESX host, is - that correct?

    If I bought 6 data center licenses (3 ESX host with 2 physical processors in each), what version of Windows server can be used, I understand his only standard or Premium, can anyone confirm this? It also covers Windows XP?

    Thank you

    > Question, I realized that a Windows license for data center would be per processor, so if I have 2 physical processorsin each esx host, I need to get 2 X Datacenter license per ESX host, is - that correct?

    Fix.

    License from Microsoft Windows Server 2008 to run with Virtualization Technologies

    Page 13:

    Instead of license servers with enough licenses Windows Server 2008 Standard to satisfy the greatest number of simultaneously running instances of Windows Server, the processors in servers could be allowed with Windows Server 2008, Datacenter Edition. This would allow an unlimited number of instances of Windows Virtual Server to run simultaneously in operating systems. Because the servers have two processors, two licenses of Windows Server 2008, Datacenter Edition for each server should be. Licenses of Windows Server 2008, Datacenter Edition provides the flexibility to move instances of Windows Server without concern to maintain the license compliance.

    > If I bought 6 data center licenses (3 ESX host with 2 physical processors in each), what version of Windows server can be used, I understand his only standard or Premium, can anyone confirm this? It also covers Windows XP?

    Anton is correct - Datacenter license covers only the OS Server.
