• VMW Virtual Machine CPU Utilization - script

  Hello team,

  As you know the virtual machine CPU usage will check for crampons, drops drama or sustained high levels in the use of the CPU on a virtual machine.

  But I'm looking Foglight to trigger alert when it reaches more than 95%, I want that all alerts to change radically.

  Here's the script available right know.

  could someone let me know how?

  history = #utilization of $scope.hostCPUs for 90 min #;

  average = avg (history);

  STD = stddev (history);

  If (mean.isNaN (): std.isNaN ()) return false;

  If (Max (History)< 0.5="" *="">

  Returns false;

  If ((#utilization de $scope.hostCPUs # > (moyenne + Registre ("VMW:cpu.)))) ((STDev.warning') * std)) | (#utilization of $scope.hostCPUs #)< (mean="" -="" registry("vmw:cpu.stdev.warning")="">

  || (#utilization of $scope.hostCPUs # > registry ("VMW:virtualMachineCPU.warning")))

  )

  Returns true;

  on the other

  Returns false;

  Thank you

  Vivek

  Hi Vivek,

  You could disable this rule of origin and create a new one with this condition:

  If (#utilization of $scope.hostCPUs # > registry ("VMW:virtualMachineCPU.critical")))

  Returns true;
  on the other
  Returns false;

  Let me know if it works,

• Difference between the hosts and virtual machines

  Happy new year!

  I guess that's a stupid question, but I don't know the answer to it.

  I created pools from VM. Some jobs in the pool are hosts and some virtual machines. What is the difference between the hosts and virtual machines. I thought I could only create virtual machines, but I guess I could create hosts as well. -What happened?

  Thanks for your help.

  where does say desktops are hosts?  A host is usually referring to an ESXi server.  A virtual machine is just the guest OS running on the host computer.  A pool is a group of VMs that can extend over several hosts.

• To cut and paste between Mac and Virtual Machine

  My husband and I have VMware Fusion installed on our MacBooks. We use it to run WIndows XP.

  His continues to have problems. Windows crash then left outstanding programs. Now, he can not copy / paste between Mac and Virtual Machine.

  I can't find all the differences in our backgrounds. I'm not having problems he knows.

  Any advice on how to solve this problem, so it can copy / paste between systems again?

  Assuming that the MAC is stable and not giving any problems I try and see why the XP VM crashes and at least re - install VMWare Tools on XP because that is what is needed to copy and paste between host and guest operating system.

  Look in XP Event Viewer to see if you can see what happens wrong... Click Start and then right-click my computer and then click on manage, and then click Event Viewer.

  Perpahs try running a virus scanner or applications malicious XP if you think that it might be infected.

  If all else fails, try and repair the machine virtual XP from your XP CD...

• ESXi on SD card and virtual machines on a NAS raid-6, performance?

  Hello!

  I'm planning an ESXi with HP Proliant DL380 G6 environment, which I already have.

  The server has an internal port SD card and according to this article , it is supported to run ESXi from an internal SD card.

  1ST QUARTER

  Someone hwo as tried this, what of the downside to this, except the redundancy on the SD card. I had a hard time finding comments on this

  Q2

  I intend to run virtual machines on a NAS via iSCSI, (thecus N8800, have another thread on the subject to know if it would work or not here)

  With this config I don't need any HD in the DL380.

  However, I do not know if a good high-performance NAS is good enough for my VMs and if maybe I need to run the OS on internal disks with higher performance.

  First of all, my plan was to run the OS partitions on a raid with internal 10 k SAS drives. And have all the data on the NAS partitions.

  But since I'm the new implementation of ESXi on SD or USB I think about the ability to run the DL380 without HD

  But, as noted above, is it possible that there is performance enough for that.

  Having in mind that my environment is and will be VERY LOW, we speak up seven windows server 2008 and totally 150 users.

  But I still haven't any idea if theres a chance that my 7 virtual machines running windows server 2008 will be capped at a lot by running NAS. The Nas will take place with eight 7.2 k RPM Sata disks, they are high of preforming sata drives, but not yet a SCSI raid. I have the ability to run a raid 10 on it instead of 6 and I will consider and try how much better performance, he gives me. 1 TB sata drives are 70% less expensive than the 300 GB 2.5 '' SAS 10 k disks.

  Yes, there is a good reason THAT SATA is less expensive than SAS.  SATA drives do not have the same command line than to use SAS drives, more the bottom of basket on SATA relies on the CPU, SAS can unload it on DEMAND.  The discs themselves seem to be competitive, but they are a far cry from the performance of SAS/SCSI, you get good performance until you start to make the e/s simultaneous sessions and hit heavily then you'll start to see performance degrades

  If do you some tests and that you are happy with it, still great.  I really hope it works well.  RAID 10 can be a good idea with SATA, which can help to compensate for this loss of performance.

  The PIN number is the best way to get the best performance, the physical drives of player throw you into a RAID of any kind the better you will be.

• go esxi hosts and virtual machines in one vCenter to another

  I built a new vCenter (Windows vCenter), I intend to move on ESXi hosts the old vCenter (Virtual appliance vCenter) to the new vCenter. I don't know if it's feasible, please notify my step is correct or not: 1) build a new vcenter 2) create a cluster with two esxi hosts first 3) Mount data (NetApp Filer Storage) to the new vCenter warehouses 4) add an empty host for the new vCenter VMs) 5 download then upload to the host in new vcenter

  Hi friend

  Its doable without any problem.

  Please follow the procedure below.

  1 build a new vCenter (your first step is correct)

  2 creating a cluster (because it is new vCenter there will not be any available host.) That is why cluster creation wizard will not get to add in the new cluster host). While initially empty cluster would be created.

  3. once the cluster is created, immediately do a right-click on the cluster and add your hosts one by one. Not necessary to cancel the registration and the VM. Virtual machines will automatically be added who were there on the data store available with all guests.

  Don't forget,

  1. we do not mount any store data in vCenter, we assemble the data store on the host.

  2. If you mount the new data store (which did not exist before), you can mount once the new hosts are added to the new cluster. (Your SAN admin help)

  3. If you want to move your virtual machines from data store before the newly added/mounted data store, please SVMotion these virtual machines (by right-clicking on the VM > migrate > data store > select the data store that is new)... Please follow the same procedure for all virtual machines.

  4. you don't need to add empty hosts to the new cluster, add just as soon as all guests without you register VMs. Later, you can migrate to other store of data according to the requirement. NO need to download or download the VM.

  5. Please make sure that your ESXi hosts will be compatible with the new vCenter. Old version of ESXi always compatible with the new version of vCenter. Just check if you have all valid licenses.

  Please let me know if you need any clarification

• Attempt vSwitch configuration change and now the ESXi host and virtual machines offline

  So I have no doubt, I have myself to blame for this one. I was trying to change my vSwitch from 100 Mbps to 1000 Mbps when an 'operation timed' error out jumps-to the top and my vCenter Server lost connection with my ESXi host. I tried to restart the host manually, but that did not help. The host is not the ping requests and all the virtual machines on that host are offline; None of them vMotion off to my other ESX Server.

  I tried to reconnect the host computer in vCenter, but it is obviously does not connect because it can't ping it. I logged the ESXi console and all the network settings appear to be correct. I'm used to connect to the ESX console where you can execute commands, but it's my first ESXi host, so I don't know what I can do.

  Any help is greatly appreciated!

  -D.

  If you had your management port and VMs on different vSwitches / NIC leave on framework would eliminate a false positive. As in your case the management port reportedly follows the cable / about speed, but the virtual machine network would be intact (and I'm assuming that your storage space as well).  In this case the VMs system would have worked very well even if the management port did not work.

• ESX, ESXi and vCenter and virtual machines

  Hello all - I need to re - certify my VCP this month so I decided to sit down this weekend to set up a virtual lab.  I managed to get ESX, ESXi and vCenter working all in s vm on my laptop in less than 4 GB.  I use Player version 3 for now.  I have Workstation 6.5 but I have to spend my VCP to get a key of 7 workstations and improve it.

  The manual is a bit long, but here is the link if you are interested.  I'll update everything to Workstation 7 after my review.  I hope that some of you find it useful!

  Nice - Thanks for posting.

  I doubt that you must update for Workstation 7 as VMplayer 3 is nothing else than a torn Workstation 7. It has the same basic functionality.

  So, nothing will be different if you use Workstation

  By the way - Starwind is really nice simulate a San.

  Another interesting thing, that you know may not...

  It is possible to assign up to 8 GB of RAM to your virtual ESXs, even if the host itself has only 4 GB of RAM.

  For this I have

  prefvmx.useRecommendedLockedMemSize = 'TRUE '.

  prefvmx.minVmMemPct = '5 '.

  in the file config.ini from the host. Do not run and then

  Using this trick, I was able to run 4 ESX virtual machines on my laptop 4 GB RAM running 2 k 3-32 bit host

• ESXi 4 hosts and virtual machines with domains and different IP addresses

  Hello, I hope someone can shed some light on this problem.

  I have an ESXi host.  It is in the 'AREA A' and has an IP address like 204.75.225.6.

  Is it possible to use the tool VMware P2V Converter some servers that are located in one field other than ESXi host and have different IP addresses?

  Example: VM candidate: in "AREA B" with IP address 192.168.1.56.

  Both domains trust each other.

  Y at - it a tip to configure the network settings on the host to allow that?

  I currently have 2 vSwitches.  One for the management network and the other is for the traffic of the virtual machine.

• Alert - the virtual machine CPU usage

  A virtual computer that is running Windows 2000 reports almost every day an alert on "use of the processor of the virtual machine.

  According to my knowledge, add a CPU to a Windows 2000 Server is not easy as with recent versions of Windows, is correct?

  The 5.0 ESXi host is not CPU ovrloaded, so I don't think that adding a CPU reservation can change anything...

  So, what is the best way to solve the problem with the minimum impact on the VM guwest?

  Hello

  because they describe your problem, read the following article:

• High using the Virtuakbox virtual machine CPU load

  I have a MacBook Pro 2.5 GHz processor dual-core Intel Core i5 (Turbo Boost up to 3.1 GHz) with 3 MB L3 cache.

  I use VMware Fusion Pro 7.0.1 (2235595) to install and use Windows 8 to run the Simulator on my MacBook internetworking solution.

  These simulators come with Oracle VM VirtualBox and they used to run in the Windows virtual machine on my MacBook Pro with no problems.

  So far, no problem!

  However, after upgrading to OS X Yosmite 10.10.1 simulators no longer work due to the high utilization of the processor by VBoxHeadless.exe

  I deleted the virtual machine, I uninstalled VMware Fusion and reinstalled, then reinstalled the Windows operating system, makes all the possible update and finally installed solutions simulators without success to have any Simulator market, they used. The reason is always high utilization of the processor by VBoxHeadless.exe as seen in the following images:

  

  I then moved to bootcamp and all do it again. Now simulators all run as before but on windows on the bootcamp partition.  Now I can even run a lot of devices in simulators like in the following photos with no problems:

  

  

  Please, do you know how I can fix this problem? I prefer to use VMware fusion because it gives me more room for what I want to achieve compared to the bootcamp.

  There is a difference between the hosts with regard to the information provided by windows on the ability of the virtualization of the MacBook.

  I thank very you much in advance!

  Kind regards

  Please note that the forum is not taken in formal charge and that this is a forum where users help other users.

  Your problem unfortunately was not something that other people recognized as a problem they had seen or they simply didn't have the time to answer.

  The majority of the Fusion users will not also have installed VirtualBox.

  However, I am glad to hear that you found a solution (in a restaurant) and please let us know.

• Script to collect some statistics on hosts and virtual machines

  I'm trying to accomplish to get the following statistics, put into a script.

  When I run this script, it must be run by "vcenter" and result the following items.

  The cluster name / number of hosts / number of computers models and virtual / assigned the total memory of all the virtual machines on the cluster (not what is actually to be in use)

  Thus, for example, in the XYZ group with 4 guests, if I have 20 MV that I have 4 GB of RAM for each virtual machine, the output should be 80 GB

  XYZ 4 20 80 GB

  I suspect that you forgot the Select at the end in order to recover the amount.

  @{N = 'CPU'; E = {}

• 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.

• The virtual machine CPU is running high

  I have a few virtual machines that use clients running very high on the CPU. Virtual machines are in a resource pool that has 200 000 mhz allocated with expandable reservation. Is it possible to give these machines more CPU cycles?

  It doesn't sound like you are running in contention in this pool - if you have limits on the RP move them - one vCPU only working with unique pool - so if your base speed is 2950 and you use all cycles of the only way is to add an another vCPU

• Taking image image redhat physical machine running on the virtual machine 1 core.

  Hello

  I am woundering no matter I would get in trouble if I toke a physical machine linux image used vmware converter to make a picture of him and installed on a virtual machine with a processor?

  I'm guessing that this might cause pilot or BONE problems.

  Someone at - it experience with this?

  Thank you

  Dak.

  There will be no real problem. Linux can work on 1core CPU even with SMP kernel installed perfectly. But it runs a bit slower due to additional unnecessary code in the kernel for synchronize processors.

  The only real problem is that you will have 1 kernel instead of able 4 times less treatment and 4.
