• How to set the processor affinity and memory.

  We have explicit recommendations of our application provider to set the processor affinity for one of our virtual machines running their product. However, this process is not quite clear to me despite the available docs. We are company ESXi 5.1 more.

  By looking at the tab "resources" for the parameters of the virtual computer you see under CPU:

  Actions (I would do that quite high so that it never goes to confront other good?)

  Booking

  Limit

  The requirement is to set aside x cores for the virtual machine while it is never claim to waiting or resource. They would also potentially implement affinity memory related to the same socket for the effectiveness of the NUMA node.

  We have a host with 2 8-core processors with 256 GB of memory. I'm not worried about the affinity of memory. This should be as simple as the control that the 'reserve any memory comments' correct?

  Is it simpler just set up a pool of resources for cela CPU and memory? The only concern I have is it if the processor uses the same memory channels. We do not want a CPU into a socket using the channel memory of another plug for this virtual machine.

  And it's too late to go back to physics for this system.

  Eeghads! Just FYI, the processor affinity is almost never what a seller really wants, even if they think they do. I can imagine there are valid use cases, but I spoke with several vendors who recommend this, and they were all wrong.

  From what I understand in your summary, the application is sensitive to the latency of the CPU. If the physical compute capacity, actions and reservations will address the latency. Latency is the only reason why they want to set the affinity, or are there others? If there is other, know what they are, because there is a good chance to those who are also invalid reasons. The processor affinity tends to exacerbate the problems you're having with loans time CPU and can often cause latency application MORE CPU than that without it. Yes, you can set up reserves of CPU to address these issues for this particular virtual machine, but you made life more difficult for the CPU scheduler. DRS involved in the loan time CPU, which means she won't necessarily move these other virtual machines on this host, even if they are jointly stop like crazy. While we're on the subject, this virtual machine would need to be excluded from automatic DRS migration, since you cannot vMotion with the processor affinity configured. It also means the virtual machine must be powered whenever his current host goes into maintenance mode.

  In any case, verification 'reserve any memory comments' will not affect memory locality. Will just leave all the pages of virtual memory with physical memory pages (another side effect interesting is that creates the virtual machine is no longer a pagefile on the boot). If you REALLY have to set the affinity to the CPU/memory, memory affinity can be set by changing the settings of the VM, the tab "resources", select Advanced Memory, and you can configure NUMBER here. In addition, if you had already seen it, the processor affinity is configured in the tab "resources", under Advanced CPU.

  I highly recommend you challenge the seller and ask if reservations CPU are sufficient. The planner of UC is already aware NUMA. VCPUs how they ask, anyway? Unless they want to more than 8, it is unlikely to split the virtual machine.

• The processor affinity and VMotion

  Hello

  A virtual machine with set CPU affinity can be VMotioned either under a DRS cluster or manually?

  Thank you

  Note that you should not use Affinity processor with VMotion.

  You can disable DRS for a virtual machine, but disable VMotion, you will need to use some tricks (like attaching a local device or an ISO local).

• I tried processor affinity and compatibility mode. Always impossible to install episode I Pod Racer... Help me? :)

  I have Windows 7 Premium Home Edition.

  I try to install Star Wars Episode I Racer. I think that it was designed for use on Windows 95/98.

  When I try to install it gives me an error and says I can install it by using the Setup program. EXE, directly from the CD. However, when I try, I get another error saying "the program or function '------?" \D:Install\Setup.exe"cannot start or run due to incompatibility with 64-bit Windows versions. "Then he told me to check with the vendor to see if a 64-bit version is available (but it certainly won't)

  If someone knows how to solve this problem, I'd be more graceful. Thank you!

• Updated my CPU (Windows 7 64-bit) and DRM rights do not seem to work for Windows Media Center

  After the upgrade, only the specific movie channels in Media center play is more (Record) after approximately 6 seconds.

  (Do not forget that there is a function of pause/forward who s equivalent to check-in for DRM)

  Get a message from copying prohibited.

  Looks like the upgrade of the processor messed up somehow DRM rights for this machine, to the point where no films previously saved are playable AND NO NEW FILMS can be registered and enrolled in some way a Canadian Film Channel. (Bell Expressvu - channels 300 + Movie Network)

  As wired http://www.microsoft.com/windows/windowsmedia/player/webhelp/default.aspx?&id=C00D2798

  Delete the contents of the file DRM (archive first)

  c:/program data/microsoft/windows/drm.

  Restarted...

  Partial contents of the folder have been recreated...

  Problem remains.

  Can Watch all the channels, but those who are 'Movie channels' stop after about 6 to 10 seconds and display a Message of copying prohibited.
  The broadcaster has banned this content to be copied. You can only read this content on the same computer on which it was recorded.
  Note: I don't like on my OLD recorded movies... In fact already deleted... I just want to be able to watch the movie channels and save NEW ones...

  Well after 4 days of effort + a fix was finally discovered...

  (1) exit Windows Media Center is running.

  (2) open a cmd prompt - run as administrator.

  (3) run the following commands one at a time:

  Code:

  net stop ehrecvr CD %programdata%\Microsoft\PlayReady del *.hds rmdir /s Cache CD %programdata%\Microsoft\ehome del *.hds rmdir /s Cache net start ehrecvr

  (4) run Windows Media Center. Update of PlayReady through tasks, settings, TV, TV Signal, PlayReady update.

  It was the only solution to Playready update succeed to in Windows Media Center.
  Playback worked immediately without any loss overall upward or configuration information...

• VSMP: Using Affinity and allocation of resources to evade planning issues

  Hi all

  I just read upwards in the http://communities.VMware.com/docs/doc-4960 about scheduling and I was wondering if set the processor affinity and allocation of CPU resources would be to circumvent the problems associated with the coscheduling. It seems to me the Scheduler would not decide what hearts to use and would be guaranteed resources on them, is that the case?

  Tom

  You decide what core use, but are no guarantee of resources on this topic.  Instead, you could hinder the efforts of ESX coscheduling itself, and if you have multiple virtual machines, then your server will actually last less efficiently than if left to its own devices.  Also, this will cause problems if you try to implement vMotion/DRS, affinity which would cause problems here.  Use the affinity with caution, it can help in some scenarios, but should be the exception and not the norm.

• Why the processor info and his memory will not display on the properties of the computer.

  When I go into properties of the computer, the processor information and memory installed in not illustrated, the fields are empty or say no information available.   How can I fix it?   I can see the processor information using Device Manager.

  In addition, SYSTEM side is not displayed but I see when I select the tools and performance information.

  The computer seems to work fine otherwise, I just want to know how and why the information is not seen in the System Properties screen.

  If the system is stable and functional, I don't think anything really to worry about.

• HP 550: updated hp 550 memory and cpu with the unconventional settings. is not ideal, but not other choice

  HI guys, I hope you can help or at least give a point in the right direction. I am a freelance photographer with a large part of the suite creative Adobe CS6. After a disaster of a week, I came home to find the motherboard on my editing station is fried somehow. I don't know what happened though I wouldn't put past my inattention of roommates.
  I'm desperate. I have to finish my current job until I'm able to afford to buy a replacement. So I have to rely on stop-gap measures, in desperation to finish my project, that are less than ideal, but so far are doing better than I'd hoped.
  Im a photographer, Capture One, Adobe Photoshop Lightroom, Adobe Photoshop and Premiere Pro are the go for workaholic applications that I need to work. without them I have no income. in order to have this machine run these applications,
  the machine I have left is an old hp 550 that was gathering dust in the closet. It was built for 32 bit Win XP and in no case is designed to run adobe products food pork I use, particularly of Lightroom.
  Unfortunately PS with Lightroom and first are 64-bit programs and LR and first are hyper threaded. so I did some research and with the help of the list of the utility windows 7 Advisor to upgrade instructions, I was able to get windows 7 Pro 64-bit to install and run.

  I know that this is not the ideal machine or the situation, but for a few weeks, I need to make it work.

  I really just 2 simple questions. First of all, I went to the HP technical support. but they were not useful. as the guarantee of the laptop are long gone, they would be not even polite and basically told me to shove off. Then on another forum, I called back and comes with a knowledge it all who constantly insisted on the fact that there was no way no how this pc could run 64 bit win 7, which i thought what am I seeing things? It works very well for 3 months. So I decided to come to you. your forums were useful on many occasions.

  Basically, I need this machine to run these programs during the next month or two, until I can buy a new machine.

  essentially, what I want to know, it's the motherboard support an upgrade of the processor? and if anything goes, what do you suggest as a substitute, given my needs? The Core 2 duo is the bare minimum of what I can limp with like photo/video rendering times are excessively slow.

  then I was talking to the support staff essential tech upgraded memory. and possibly set the bios to force to run 8 gigs of ram. They said that they have cold cannot find any version of bios that would make that possible, but only by forcing already run 64 bit, which has already allowed the pc to use the full 4 GB of ram, which was impossible in the 32-bit format. He suggested that I buy 2 4 gig modules such as 4 GB DDR2 PC2-5300 unbuffered NON - ECC, 1.8V 512Meg x 64 which can be seen at http://www.crucial.com/usa/en/memory/ct51264ac667 and try to install the full 8 concerts and see what would happen, saying that he had a feeling that I might get lucky. his logic is that the 64-bit system already open the ram limits and who knows, you can't make an omelet without cracking of eggshells! It seemed very optimistic. So, what do you think? It seems likely you because I love to work. or do you think the guy was a quack? and this whole endeaver is a waste of time and money?

  also, any other suggestions on how to time this month long storm that do not involve suggestions of buying new machines would be appreciated!

  Here is the Manual:

  Unfortunately, the maximum configuration is a processor T5670 1.8 ghz and 4 GB of DDR2-667 memory, you already have. The CPU includes the 64-bit instructions is not surprising, that it can run Windows 7 64-bit. My best advice is to save your money for when you can get a real working machine. The only other likely to help is a solid state drive, you might use in the laptop and then also use the new computer that you intend to buy.

• Request to modify the script to collect the CPU Ready in percentage by VM instead of milliseconds

  Hi all

  I would ask for help here with the script that I found in this forum by Mr. LucD to collect % VM CPU ready to be changed according to the famous formula for calculating the percentage of CPU of VM ready:

  ((Valeur de sommation UC / (< intervalle de mise à jour par défaut graphique en secondes > * 1000)) * 100) / number of vCPU = CPU % ready

  
  

  
  

  From my understanding, the script must be changed because:

  1. Don't divide the percentage CPU Ready by the number of vCPU for each virtual computer
  2. The refresh interval is not set 'for a week. for simplicity, this script will be used to collect last week performance data ($start = (Get-Date). AddDays(-7))

  Note: The refresh rate can be found this KB: VMware KB: conversion between the summation of values CPU and CPU ready %
  

  the purpose of this script is to classify VM of the result is greater than 10% determined as having problems with CPU Ready. Article source: http://docs.media.bitpipe.com/io_10x/io_107330/item_605784/Basic%20VMware%20vSphere%20Performance%20Guide_201211.pdf)

  I have tested and run script below:

  $allvms = @()
  $vms = Get-VM  
  $start = (Get-Date).AddDays(-7)
  $metrics = "cpu.usage.average","mem.usage.average","cpu.ready.summation" 
  
  
  Get-Stat -Entity $vms -Start $start -Stat $metrics | 
  Group-Object -Property {$_.Entity.Name} | %{
    $cpu = $_.Group | where {$_.MetricId -eq "cpu.usage.average" -and $_.Instance -eq ""} | Measure-Object -Property value -Average -Maximum -Minimum
    $mem = $_.Group | where {$_.MetricId -eq "mem.usage.average"} | Measure-Object -Property value -Average -Maximum -Minimum
    $vmstat = "" | Select Time,VmName, MemMax, MemAvg, MemMin, CPUMax, CPUAvg, CPUMin, CPURDYMaxPercent
    $vmstat.VmName = $_.Group[0].Entity.Name
    $vmstat.Time = $_.Group | Sort-Object -Property Timestamp | Select -First 1 | Select -ExpandProperty Timestamp
    $vmstat.CPUMax = [Math]::Round($cpu.Maximum,2)
    $vmstat.CPUAvg = [Math]::Round($cpu.Average,2)
    $vmstat.CPUMin = [Math]::Round($cpu.Minimum,2)
    $vmstat.MemMax = [Math]::Round($mem.Maximum,2)
    $vmstat.MemAvg = [Math]::Round($mem.Average,2)
    $vmstat.MemMin = [Math]::Round($mem.Minimum,2)
    $vmstat.CPURDYMaxPercent = &{
    $interval = $_.Group[0].IntervalSecs * 10
      ($_.Group | where {$_.MetricId -eq "cpu.ready.summation" -and $_.Instance -eq ""} | 
    Sort-Object -Property Value -Descending |
      Select -First 1 | 
      Select -ExpandProperty Value) / $interval
    }
    $allvms += $vmstat
  }
  $allvms | Select Time,VMName, MemMax, MemAvg, MemMin, CPUMax, CPUAvg, CPUMin, CPURDYMaxPercent | 
  Export-Csv "C:\TEMP\AllVMs-7days.csv" -noTypeInformation -UseCulture 
  

  I hope that this will be the most useful script to understand where particular VM is experiencing problem with percentage CPU Ready.

  Thanks in advance,

  I have my version here, I use to use of the CPU.

  {Function Get-Ready

  . LOGBOOK

  This unique feature provide several reports and information. IE: convert ready value into a readable format (for real-time, day, week, month, year).

  . DESCRIPTION

  This unique feature provides multiple information of esxi host, as the list below.

  The CPU usage of the virtual, Mhz, the use of the processor CPU ready computer

  vCPU allocated to the VM (jailbroken in the casings and core)

  VMHost name

  Information physical VMhost CPU (jailbroken in the casings and core)

  To convert between value of CPU ready summons in vCenter performance tables and the value of loan % of CPU that you see in esxtop, you must use a formula.

  The form requires that you know the default update intervals for performance dashboards. These are the default update for each chart intervals:

  Realtime: 20 seconds

  Last day: 5 minutes (300 seconds)

  Last week: 30 minutes (1800 seconds)

  Over the past month: 2 hours (7200 seconds)

  Last year: 1 day (86400 seconds)

  To calculate the % of CPU ready of the summation value ready CPU, use this formula:

  (Value of summons UC / ( * 1000)) * 100 = ready % CPU

  Example: Stats in real-time for a VM on vCenter may have an average CPU ready summation value of 1000. Use the appropriate formula values to get the loan % of CPU.

  (1000 / (20 sec * 1000)) * 100 = 5% CPU ready

• Question about on VM consolidation number and percentage of CPU Ready

  Hi people,

  I'm trying to consolidate as many VM in simple ESXi servers on HP on AMD Opteron blades with 32 CPU available logic (based on the number on the vSphere console)

  Can anyone here please share some thoughts and comments about what is the best indication to avoid adding more VMS that ESXi hosts can treat?

  I must ensure that the number of vCPU altogether exceed is not 32 logic processor available, or it can be more than that?

  Running a script powershell LucD to collect CPU ready percentage shows that some virtual machines had prepared more than 10% CPU (for the most part 2 x vCPU) up to 22% (this one with 8 x vCPU)

  Hello

  I had the same situation on HP Blade and DL serer with two different CPU vendors.

  Intel CPU based on my experiences, has better performance compared to AMD CPU when the CPU is too committed on ESXi server.

  I have HP BL460c G6 and G7 on one of our sites, the server has 12 physical and 24 cores logic core.

  I assigned four cores to each customers (to fix the voice problem) and virtual machines are working properly, RDY CPU is less than 5% in general and there is no performance problem.

  Each blade server hosts 20 VMs and total virtual cores are 80 cores, so we attribute 1:3 (Physics: virtual) core.

  On the other hand, I DL585 G7 on our sites some server has 64 physical cores (4 Sockets and each catches have 16 cores). Servers host 50 active VMs usually but RDY CPU is greater than 10% or 7% on them. Total virtual cores are 200 and CPU assignment ratio is 3.

  I think that, if you want to optimize performance on AMD CPU, 1:1 or 1:2 CPU assignment report is the best choice.

• waiting for CPU and cpu ready

  Hello

  We have very high CPU wait times on our virtual machines (19000ms).

  We have also very low cpu ready time (20ms)

  I did notice on one of the 2 networks performance issues

  I was hoping someone could give, in terms laymans terms, a definition of waiting for cpu and cpu ready.   The technical definitions I've seen online were not very clear to me.

  Also - who would be initially high such a timeout of the CPU on the virtual machines?  It seems to be that the same time limit on all the VMs on the server whether or not they have 1 vcpu and memory 2 or how much they were awarded.

  Info about our server:

  HP Proliant ML350G6

  CPU cores: 4CPus x 2,555 GHz

  Processor type: Intel Xeon processor x 5550 @ 2.67 Ghz

  processor socets 1:

  Logical processors: 8

  Hyperthreading: assets

  No vm: 33 (especially Server 2003 Server VM)

  Enjoying any assistance.

  Kind regards

  Simon

  CPU wait time is the time a virtual machine did get on demand, but the processor has

  Nothing in the process and so the CPU to simply waiting for then the time scheduled for the virtual

  machine clicks by.

  CPU Ready is the time that the virtual machine is ready, but could not get scheduled to run on the physical processor.

  Bascially ready cpu the prompt is queued on the host computer, waiting for cpu means that the host is queued on the prompt.

• DRS and CPU % ready

  What VC & DRS seem to make decisions to migrate virtual machines with respect to the use of the processor?  Is it only in overall CPU utilization on ESX hosts in the cluster or is he looking at other factors such as the ready values % of CPU on the host computers?  For example, that you have a 16 core host and several 4 virtual computers vCPU that perform poorly and have very high CPU % ready times, but the overall use of the CPU on the host computer is low, DRS trying to rebalance these virtual machines?  Thank you.

  I made this request even in queries.  Now its only looking at the CPU usage and does not know about the other factors regarding the use of the CPU.

  I had some older hosts that while the CPU was used only to values of RDY % medium, about 30% were constantly 5-15 then it became unacceptable and once DRS passed everything was when one or more of the virtual machine started going to 100% on my old plug cores doubles one.  New hardware that resolved completely so (more than hearts) for me so it's not a problem anymore for me.
