Question to get the maximum virtual machine via powercli read IOPS / s
Hello
I use this script REPORT maximum and average OPS / s (writing & reading) based mainly in this script by LucD vmware communities user:
$datastores = "datastore.*" EMC - LUN. * | "SAN - vm.."
$MinIOPSWriteMax = 10
$MinIOPSReadMax = 10
$metrics = "disk.numberwrite.summation", "disk.numberread.summation".
$start = (get-Date). AddDays(-1)
$report = @)
$vms = get - VM | where {$_.} PowerState - eq "Receptor"}
$stats = get-Stat-Realtime-Stat $metrics - entity $vms - start $start
$interval = $stats [0]. IntervalSecs
$lunTab = @ {}
foreach ($ds in (Get-Datastore - VM $vms | where {($_.)})) Type - eq "VMFS") - and ($_.) Name - match $datastores)})) {}
$ds.ExtensionData.Info.Vmfs.Extent | %{
$lunTab [$_] DiskName] = $ds. Name
}
}
$report = $stats | Group-object - property {$_.} @entity.name}, Instance | %{
New-object PSObject-property @ {}
VM = $_. Values [0]
Disc = $_. Values [1]
IOPSWriteMax = ($_.) Group | `
where {$_.} MetricId - eq "disk.numberwrite.summation"} | `
Measure - Object - property - maximum value). Maximum / $interval
IOPSWriteAvg = ($_.) Group | `
where {$_.} MetricId - eq "disk.numberwrite.summation"} | `
Measure-object-propriete value - average). Average / $interval
IOPSReadMax = ($_.) Group | `

Measure - Object - property - maximum value). Maximum / $interval
IOPSReadAvg = ($_.) Group | `

Measure-object-propriete value - average). Average / $interval
Data store = $lunTab [$_] Values [1]]
}
}
$report | IOPSWriteMax tri-objet-descending | WHERE-object {($_.)} IOPSWriteMax - ge $MinIOPSWriteMax) - or ($_.) IOPSReadMax - ge $MinIOPSReadMax)} | Select the virtual machine, disc, Datastore, IOPSWriteMax, IOPSWriteAvg, IOPSReadMax, IOPSReadAvg | more
Is this a normal behavior, still getting 0 in all the IOPSReadMax vm?
Thanks in advance.
Best regards

You have just a typing mistake in the name of metrics here ("numbertread" instead of "numberread"):
where {$_.} MetricId - eq 'drive. numbertread.summation '} | `

Cultivate a disc of virtual machines via PowerCLI
Hello
I'm looking to cultivate a few volumes on some servers via PowerCLI. I got the code to extend successfully the volume inside the prompt below OS once I increase it configured size through the user interface.
Hard drive get "name VM | where {$_.} {Name - eq ' hard disk 2 "} | Together-hard drive - CapacityGB 20 - ResizeGuestPartition-confirm: $false
My question is:
Is it possible to increase the size put in service of a disk via PowerCLI I could run before the above code that extends the volume inside the guest OS?
Thanks in advance for any help!
As each correct answer, I'll have to start with "it depends".
If this isn't the vdisk that contains the system partition, you can simply use the hard drive Set cmdlet with the CapacityGB parameter. See example 2.
If it is the system partition vdisk, you need to use the parameter HelperVM of the cmdlet Set - hard drive .
Note that the virtual machine and the HelperVM both must be switched off!

As much as I know there is no cmdlet PowerCLI for this, but you can use the Invoke-VMScript cmdlet and interrogate the Win32_Product class.
By running the following. You can add a Where clause to return only the Agent of the view

expose the virtual machine via home router
Hello
I have my router configured to allow access to a virtual machine running Ubuntu 64 bit headless. The router allows port 80 to pass to the virtual machine. I was able to access the machine's web server once and then I get an error saying that the connection has expired. Determine, I can connect to the Web server on the computer virtual machine host through the LAN IP. I tried bridged and NAT.
When debugging this issue, I changed the configuration of the router to allow access to port 80 on the host computer. This succeeded and I see VM host machine from outside my local network.
I looked around your site and google, but I can't use the correct search terms. Can you point me to the documentation for it or let me know how do ?
Thank you
-Rob
If you use the NAT, the virtual machine is originally a host-level NAT address (172.x.y.z) that your Internet router knows nothing. You can forward port 80 on the router IP of your host, and then configure/Library/Application Support / VMware Fusion/vmnet8/nat.conf port 80 requests for port forward to address 172 of your VM on port 80. Need to turn off Apache on OS X, if it works because it would cause a port conflict.
Your other option is to change the VM from NAT filled, in which case your OS X and your Ubuntu VM would be on the same subnet with a DHCP address, given by the Internet router. The router might forward traffic directly to the virtual machine without any additional port forwarding.

newbie question - vmdk transfer on another virtual machine on the same host
Hello
can I transfer a vmdk 1 vm to another and mount it?
I have a vm of windows server with a 2nd virtual hard drive that has data on it. rather than to make a copy of file in a file to another virtual machine with a 2nd hard drive and then delete the second original disk, could I just disassemble and remove the second hard drive to the original virtual machine and then attach it as an extra hard drive to the second vm?
pointers would be appreciated.

Two POS devices back up the same virtual machines
Hello
So my goal is to have weekly backups to a unit of POS, and monthly backups go to another device of POS, on a separate data store. I'm stuck on VDP v5.1.1 because since I can not upgrade my vCenters yet. What I'm trying to do, is to protect my backups to a store of data or corruption VDP OS - which have already occurred in the past.
My question is, I'll be able to simply deploy a 2nd POS device and tell it to save the same virtual machines that are already underway by the 1st POS device? I wonder what that complications would be, i.e. If the 2nd POS only runs a monthly backup, it will be smart enough get all changes since the last monthly backup or he'll come CBT files since the last daily backup of the 1st POS device?
Thank you!
You can make backups in this way with 2 POS devices and CBT is treated properly. Monthly backup will take more time because of the higher number of changes. Look at the time of the departure of the backups, they will take parallel steps.

People,
This issue has been resolved,
Details of the problem:
RAM 512 MB only, use JVM parameters
"" Arguments of memory in JAVA: -Xms512m-Xmx512m ".
If WL struck to use more memory for the start and the stop MedRecSvr2, 3 (managed server)
Please read the following steps to correct,
1. open Oracle VM Virtual box
2. go to settings and select the system option (make sure that all OS turns off).
3. go in card mother in this window select Base memory previously is changed to 1920 MB (1.875 GB) 512 MB.
4. click on Ok.
Then the allocated RAM will be more, for Weblogic doesn't get knocked because of insufficient RAM memory.
Respect,
Bouchra Arun
Please Mark Helpful / good answer

is it a good idea to run the JAVA virtual machine inside the hypervisor?
If I want to write a global user inside the hypervisor platform and you want to reuse some java lib, it's a good idea to install and run the JAVA virtual machine as part of global programs of the user inside the hypervisor? Thank you.
Maybe you listen to the wrong people?
The ESXi hypervisor is pretty well stripped of the linux console you are talking about, there is a thin busybox linux like environment, but you are strongly advised not to run anything in there.
Performer of applications within this console may have all kinds of side effects such as severely affect the performance of your computer virtual guests.
Why the hell would you want to run the JAVA virtual machine inside the hypervisor? What is the reason why you want to do this? If it's because you get a better return, then you're wrong, the console becomes just a little bit of resources available on your host computer.
If this is to go directly to the features that the hypervisor provides then the VMA we're talking is the answer.
So getting back to your question initial for EACH use case that I can think it's a very bad idea.

I have read and found some documents on ESXi.
According to the documents, I know that ESXi free version does not support some advanced virtual machine configurations and does not support write to ESXi host permission. But when I download ESXi from vmware.com, I can't find the free version. He will always be a trial of the licensed version edition because I can always do the configuration of start and stop virtual machines via vSphere Client installation. I can also run scripts (lamw) pl in vMA to stop the ESXi host (authorization to write ok?)
Then I confused. How can I get the really free version of ESXi? Or will the free version after 60 days of evaluation?
Start/stop above configuration is in vSphere Client via 'Configuration'-> "start/stop VM"-> "Properties"... «-> "Allow the virtual computers start and stop automatically with the system" actions setting and stop virtual machines can be configured to "comments"turn off computer"or"Suspend".» Can any body tell me if it's supported by ESXi free edition?
Is the free version of vSphere Client too? Because when I use the vSphere Client, he told me that I have 60 days of evaluation. This confused me again. I think that vSphere Client is always free, am I right?
Any suggestion or advice is much appreciated. _
Micky
Configuration of start and stop virtual machines is available with the free version and licensed, with the free version you would be configured everything via vSphere Client, where as with a licensed version, you can optionally use scripts to configure it and also issue restarts/stops using scripts.
Second, shutdownHostViaSOAPAPICall.pl for the version licensed and free of ESX (i), this script will work in both free and licensed because it uses direct SOAP calls emulating the vSphere Client communication. Take a look at the documentation for details, but this of course is not supported by VMware.

Cannot create an instance of the java virtual machine
Hi when I try to launch my sql developer get this error
Cannot create an instance of the java virtual machine located in the path C:\Program Files\Java\jdk1.6.0_38\jre\bin\client\jvm.dll, but I do not have the file in the location
I'm trying to do
BI CHAOS: SQL Developer: cannot create an instance of the Virtual Machine Java
Cannot create an instance of the Virtual Machine Java
but am not able to locate file product.conf in my machine
OK, we lost time because you said never explicitly release of SQL Developer in use, and then, when I deduced this wrong, you went right with it, rather than correct me. Remember the line from Blade Runner when Harrison Ford hits Rutger Hauer in the head with a pipe? Than hurt!
Anyway, since the last post (because of the osgi references in the file ide.conf) I see that you are using a version 4.0.x of SQL Developer. You must update the file product.conf with the smallest Xmx value in order to create an instance of the JVM. If you have not yet found the product.conf file on your system, this might help: http://www.thatjeffsmith.com/archive/2013/12/oracle-sql-developer-4-windows-and-the-jdk/
Otherwise, ask someone in your organization COMPUTER help - keep in mind that AppData is one of those hidden Windows directories, so you'll have to tell explore to make it visible by the organize > Folder Options > view > hidden files and folders parameters. In addition, you should use Java 7, not Java 6 - try to get that upgrade to the latest version of jdk1.7.0_xx (currently 60, I think). Since you never said if your JDK is 32-bit or 64-bit, I can not say to use an AddVMOption, Add32VMOption or Add64VMOption.
Best wishes

Manual removal placeholder VMs when the protected virtual machine is removed
We run SRM 5.5. We had some VMs protected, we need more, so they have been removed from the drive (I can't). When I found out about it, I went in SRM and removed the protection for these deleted virtual machines. Most of the VMS placeholder have been correctly removed by this procedure, however, I see still 2 VMs of space reserved for virtual computers that no longer exist. No idea why only these 2 (about 6) were not cleaned.
My question: can I remove manually just these VMs placeholder? They are not in any group of protection, or the stimulus plan. And the protected virtual machines which correspond to these placeholders no longer exist. It's as if they are zombie placeholders. :-)
There is no problem with me removing the VMs placeholder manually, y at - it?
Hello
Yes, its safe to delete the place holder vm. Make sure the source VM is not protected and no replication is configured. Restart the SRM service.
Thank you
