• Correct allocation of the vCPUs for virtual machines

  Hi all

  We have a physical server with 4 x Quad Core XEON E7310 1.6 GHz CPU

  VMware ESX 3.5

  We have 3 VMs that are assigned to the server

  VM1 (Production Server) as a result of config

  4 vCPUs, 16 GB of RAM and works according to:

  OS - Windows Svr 2008 R2 (64-bit)

  MS SQL Server 2008 (64-bit) (a database with the data of a line and two newspapers file)

  IIS7 with only a single application of ASP .NET (the App-based eXpress Foundation (XAF) from DevExpress) running in Classic .NET AppPool (a work process)

  Connection string Web Application points to the database on the same server (local)

  Web app has a userbase of around 250 users

  VM2 (Dev server) is the same as VM1 except it has only 8 GB of RAM

  Now 4 x 1.6GHz Quad Core CPU = 4 x 4 x 1.6 GHz = 25.6 GHz

  VM1 received 16GHz (reserved) and can use available CPU if necessary.

  Our problem is that when we don't have 10 users on VM1 it grinds to 80-100% CPU usage.

  Usually just open the app on VM1 is slower than if I use a laptop as the server.

  What can we do to improve the speed of VM1?

  Thank you!

  2 things.  DISC is your problem, not CPU.  It can run at 100% CPU, but it's probably because that the e/s DISK is queued up, and thus the CPU is waiting for data.

  try to reduce the CPU at only 2 vCPU, not 4.  More CPU for physical machines working, but the virtual computer without CPU more due to the work of how virtual machines (the same problem applies to any product of virtualization).

• Virtual machines, run extremely slow when the console is consulted 2 virtual machines Windows Server 2008 64-bit, Windows Server 2003 32-bit, 2 VMWare for virtual machine

  I'm in a difficult situtaition here.  I am the daily contact with a new client.  My linux guy, who is also my boss who is very busy, asked me to do some research trying to find answers for what's not on this server. We have a dual Quad Core 2.5 Ghz Lenovo server with 10 GB of ram.  2 500 GB hard drives are Raid 1.  We run Virtual Server VMWare 2 on a Debian with Gnome installation as a user interface for the side of things Linux.  Grub is the boot loader. There are two virtual machines running on the server.  The one machine that serves as a domain controller is a Windows SBS 2008 Server 64 bit, and the secondary machine has no responsibility domain.  The second machine is a Windows Server 2003 32-bit.  the 10 GB of ram 6 GB is allocated to the SBS server and 4 GB to the 2003 server.

  The problem I am running into is that everything is so slow, especially if I connect remotely to do any sort of administration on the network.  Some examples of issues I've noticed is that as soon as I log on the server via Remote Desktop SBS console management Windows Server spike to 80-95% CPU usage and it will not stop unless I close the management console.  Another instance is that if I open Backup Exec 12.5 on the SBS server it will kill the speed of the processor as well.  Long story short, there are a lot of machine to do what we need to do, but something is not configured right and non of us know what it is.  Another point to note is that the server has been in production for about 3 weeks, and the server seemed to have locked up just twice.  My professional guess is that over time, some chose thing is eating causing the crash of the memory.

  Sorry I do not have much technical insight on this topic, but this is the best I have to offer.  Any questions you all have, I'll ask my people and see if I can answer, but I could really use your help here.

  Thank you in advance,

  Heath

  2 things:

  1 you really need hard drives more than 2 in a RAID 1 for proper performance under load. More disks the better. Although I don't think that's what your problem is, he'll probably be the problem Next you will do.

  2. I don't know exactly where the configuration file is on your box of Debian for VMware Server, but you should consider adding the following options in the configuration file (on windows, it's the vmware 'config.ini'):

  prefvmx.minVmMemPct = "100".

  MemTrimRate = 0

  sched.mem.pshare.Enable = "FALSE".

  mainMem.useNamedFile = "FALSE".

  If you do some research, you can read about what these options (the largest is the memory page sharing - it should only be left on if you have a bunch of similar virtual machines running on the same box, that you don't have.) I honestly know why this is on by default, he kills the CPU when virtual machines are running different operating systems). These are the options that I now use standard in VMware Server deployments, with huge performance increases after you have added the. Just give a try.

  Edit: Also make sure that you have installed in your virtual machines VMware tools.

• Folder path as a VM property - for virtual machines in a paralytic

  Hello

  I used the new-viproperty of LucD script to create a folder for each virtual computer property in my inventory. It works perfectly well for virtual machines, but not for virtual machines in a paralytic as these do not have a 'record' in powercli property. they report a $null value.

  Would be much appreciated if someone can help me to modify this script so it creates a VM property for the VMS and VMs in a paralytic?

• Use the diskette of esxi for virtual machines

  Hello
  I would like to set up a lab and I have hp g6 server but just with a single 600 GB sas disk
  is it possible to install esxi on it and also use it as a storage device for virtual machines on?
  I know that I can install esxi on a cool drive but if what I've said, it's possible I prefer to use that
  Thank you very much

  It's true.

• 1 or 2 processors? 32 or 64 bit? for virtual machines

  I had a discussion with the network administrator about using 2 processors and OS 64-bit for virtual machines.

  It uses 1 proc and 32-bit on Proliant G5 servers for virtual servers ordinary.

  When it will be beneficial to use 2 procs and 64 bit?

  THX.

  Hello.

  When it will be beneficial to use 2 procs and 64 bit?

  It will be useful to use 64-bit when you have an application that you want to run 64 - bit, and it will be useful to add a second processor when you discover that a vCPU is not enough.  If by 'regular' virtual servers, you're talking low-end Windows servers, then the 32-bit single vCPU approach will be generally better.  Without knowing more about your applications or operating systems, it is difficult to give a more precise answer.

  Why do you think that you might need for 64-bit or 2 vCPUs?  Can you elaborate on what you put on foot?

• Search for virtual machines with function "Shared Folders" (HGFS) running

  I'm looking for advice on creating a script to find all VM with HGFS running, or where the service is actually used.

  Apparently, VMware posted the notice of security VMSA-2016-0001 | United States yesterday and my security people are panicking.

  Any information you have would be useful.

  Thank you

  Ludi

  The only way I know is questioning the guest operating system itself and check the registry path:

  HKLM\System\CurrentControlSet\Control\NetworkProvider\Order

  and check if the value string ProviderOrder hgfs, vmhgs or vmhgfs.

  You should remove these values and restart the virtual machine for the change to take effect.

  Wise PowerShell:

  $VM = get - VM NameofVM

  $Reg = [Microsoft.Win32.RegistryKey]: OpenRemoteBaseKey ("LocalMachine', $vm.extensiondata.summary.guest.hostname")

  $RegKey = $Reg.OpenSubKey("System\CurrentControlSet\Control\NetworkProvider\Order")

  $RegKey.GetValue ("ProviderOrder")

  VMware KB: Guest Windows cannot update hgfs.dat or vmhgs.dat

• How everyone counts the total amount of GHz for virtual machines on a host-cluster?

  Hello

  I want to do some basic sizing and I may\may do not go the way to write about it.  For example, suppose I have a cluster of 4 nodes with a total of 200GHz and 1 TB of RAM on all four hosts with 100 VM.  How can I get the total amount of GHz\Memory that each virtual machine is configured with (not necessaryly to aid real-time) so that I can workout or demonstrate what fits on one or two hosts in the cluster, for example?

  Thanks for your help and advice in advance

  You can do this via the inventory tool called RVTOOL which allow you to do an inventory of all your virtual machines and hosts with the resource assigned and served. hope, it will help you.

• Attached device PCI host to query for virtual machines

  In the web client, on a host, we can see in the peripheral PCI if one or several virtual machines are attached to it. The field is called "VMs using it."

  I was passing through the API Explorer but unable to find a way up to even with Orchestrator - to find out if a host PCI device is to be used by any machine virtual or not. Is this possible?

  If anyone is interested, this is the solution;

  var features = host.configManager.graphicsManager.graphicsInfo;

  for each {(device in devices)

  If (device.pciId.match("46")) {}

  System.log (Device.VM);

• What is the type of object to use for virtual machine model in the Points of Extension?

  Hello

  I added my plugin point of extension vsphere.core. ${objectType} .monitorViews. My plugin is for all types of objects (vm, file, vApp, resourcePool, etc) except the model of the virtual machine. My understanding is that the vm object type would be required for the virtual machine template, but that doesn't seem to be the case. Am I missing something here? Should the plugin appear for the model of the virtual machine when I use the vsphere.core.vm.monitorViews extension point?

  Thanks in advance.

  Kind regards

  Ashutosh

  Sorry, I got confused by your original question. ExtensionPoint id you are looking for is the one for adding views a model virtual machine monitor tab:

• define an id scsi for a disc newly added for virtual machines via script

  Hi Experts,

  I used the script below to add disks to several virtual machines
  http://blog.mattvogt.NET/2013/03/14/PowerCLI-mass-add-hard-disks/

  But currently our requirement for change as if we must add 3 2 GB drives, the disks must the controller use SCSI (1:0) - (1:2)

  And next bunch of disks, for example, should use use SCSI (2:0) - (2:2).

  Y at - it an option to set the SCSI ID when adding new disks.
  Please let me know if there is nothing we can achieve through scripts.

  Thanks in advance.

• How to install VMplayer 3 network for virtual machines to comminicate with each other?

  People,

  Hello. I use VMPlayer 3.

  SE host: Windows 7
  Comments to: Windows XP and Oracle Linux 5

  I need to set up the network and activate Windows XP communicate with Oracle Linux 5.

  I followed this tutorial http://www.vmware.com/support/ws5/doc/ws_devices_serial_2vms.html to configure 2 virtual machines in Windows 7 host machine.

  I tried to test 2 virtual machines in the way as below:

  In Linux, [user@localhost ~] $ping WindowsXP_HostName
  Release: Unknown host WindowsXP_HostName

  
  At the Windows XP command prompt:
  C:\ping localhost.localdomain
  Its release: ping localhost 127.0.0.1 with 32 bytes of data...
  Reply from 127.0.0.1: bytes = 32 time = 2ms TTL = 128

  
  He meets a few times and then disconnected by itself. It seems that Windows XP is ping itself and not Linux server. The host name of the Linux server is 'localhost' as well. It is a kind of confusion for me.

  
  From the information above, we can see that 2 VMs cannot connect between them.

  Can any folk provides a tutorial or example or case study to set VMPlayer 3 allowing 2 virtual machines communicate with each other by step?

  Very grateful in advance.

  In the guest machine, all I see is click on VMplayer-> VM-> settings-> network-> Network adapter Connection-> select Bridged: directly connected to the physical network. After that, nothing to keep.

  That's it for the network card in Virtual Machine of its parameters, and the rest is done to each guest at the guest OS level.

  In Windows 7 host machine, I don't see anything first.

  What we need to do is to assign 3 IP addresses to 3 machines: Win 7, Win XP Guest and Linux host.

  Why the world can't bring you up Google in a browser and type, the ip static windows xp, then static ip rhea of windows 7 and finally static ip.  As I have already said there are more then enough tutorials on the Internet about how to configure a static IP address by a given operating system then I suggest you Google it!  It makes absolutely no sense to write the instructions step by step for you when there are already dozens of tutorials available on the internet.

• What is the I/O profile for virtual machine workload?

  Hi all

  As we know, different applications may have different profiles of I/O, for example. OLTP system would generally with [random, samll, report R/W 7:3]

  1. What is typical I/O profile for a virtual machine VMWare?

  2. do you have a guide of best practices configuration for SAN storage LUN available?

  Thx a lot!

  1. What is typical I/O profile for a virtual machine VMWare?

  2. do you have a guide of best practices configuration for SAN storage LUN available?

  There is absolutely no such thing as a 'IO profile' typical of a VMware VM. Always, forever everyday, depends on.

  A hypervisor sits between the OS and the Application and the storage Bay are not because the needs of profile and e/s storage are suddenly turned upside down or scrambled at random in all directions.

  An inactive VM does not generate any more or different IOPS / s only idle physical server. A busy database VM behaves different than a physical server with the same database/application in terms of IOPS profile / s and e/s either.

• Need a script for virtual machine availability

  I know there is a metric for sys.uptime.latest which pulls the elapsed time in seconds surveyed of the virtual machine startup. Two questions

  This allows VM cacluate uptime in a perspective of avalability host?

  It only takes into account availability time between reboots to the vCenter level, or it takes into account all the running time? (example: uptime since a restart triggered via vCenter client vs a shutdown - r resulting in a virtual machine)

  Does anyone have a scipt that could be used or modified to give VM uptime? PowerGUI has a performance data plugin which can show it on a unique basis of VM. But I need to interview all the data for the whole vCenter and all virtual machines.

  Thank you!

  The metric of sys.uptime.latest gives you the time since the last poweron of the virtual machine.

  All reboots of BONE, of in the comments or via the vSphere client, do not reset the counter.

  This script gives you a report of the availability for all your virtual machines

  $vms = Get-VM Get-Stat -Entity $vms -Stat sys.uptime.latest -MaxSamples 1 | ` Select @{N="VM";E={$_.Entity.Name}},@{N="Uptime";E={$_.Value}}
  

• SRM failover for virtual machines but not all VMDK disks to include

  Hi, I have a number of VMs that need failover protection, but not all the VMDK disks must be included when switching to the opposite site. For example, a virtual machine can have 3 discs and players only need 1 & 2, switch to the recovery site - SRM can be configured to ignore the 3rd disc?

  Thank you

  I was not aware of a fact that replied vmdk cannot be detached. I think that this is normal.

  Why you are replicating data, you do not need? You can place these VMDK on LUN not replicated?
