Create a VM - virtual Sockets vs virtual cores
I don't know where to post this.
I'm a bit confused on when you create a virtual machine, you now get an option to choose the number of sockets or cores. IE 4 Socket 1 kernel, or 2 taken 2 hearts.
I've heard different reasons to different vmware trainers
Since then, it is only for the licenses that it does not matter. Must match your numa configuration or you'll have performance problems.
Me I always thought it was just 4 cores for vm - little matter how he got there.
Could someone explain this to me please.
Hello
NUMA configuration affects your performance.

Please let me know if this does not answer your question.
Thank you

create a new virtual machine with the default settings?
I was wondering if there was a way to create a new virtual machine with the default settings.
For example, let's say I want all new Lion VM to have 2 CPU cores. Is there a way to set this automatically? There are other parameters I want a new machine to inherit automatically, I was wondering if there is an automatic way to do this, or is it a feature request...
Thanks in advance

Just for my clarification, when you say a vm model, basically I would execute a finder copy then drag back to the VM library, right?
Yes.
On the orders of spcirpting, it would be unix commands or are there specific vmware controls that make your job easier (in Applications/VMware\ Fusion/content or elsewhere)...
IIRC, VMware Fusion 3 and later versions has an AppleScript dictionary, but it is not yet officially supported and may not be able to do what you want so, basically, only Unix Shell scripts, that's what I was referring to. For an example, see my script attached to the following response: Re: vmware - script of the creation of the vm and the operating system installation process

Hello gentlemen,
I can not only save this virtual machine with Backup Exec 2014 for a long time.
They are there was no snapshot in snapshot Manager.
Could you help me?
Hello
I found the solution.
I disabled the JOB BE general relativity.
and the host where the virtual machine belong was not the right time. No Ntp server has been configured.
I did and now there works.
I think that the problem can come from this.

VMware workstation, crashes when I try to create a new virtual machine
Hello
I never had this problem before, but I didn't create a new virtual machine in a very long time. Last time I created one was making Workstation 9 I think. Some time after the upgrade to Workstation 10 or 8.1 of Windows Update 1 it has started.
In 10 Workstation running on Windows 8.1, I select the file > new Virtual Machine dialog coming upwards and in a few seconds crashes of VMware workstation and closes.
So I checked the Windows event logs and find
Warning "VMware Workstation to function properly, must be reinstalled after the upgrade to Windows."
So, I upgraded from 10.0.2 to 10.0.3 and it uninstalled and reinstalled but I still get this warning.
Followed by an error

Well, I found the problem.
I looked in the UNK file and found a few ISO files wrongs tracks.
I had mounted some ISO in the past and they have made the entry in this file of preferences such as "isoLocationMRUx".
I'd change the leter this ISO file player so they could not be found as input, once I corrected the paths I can now create a new virtual machine.
He is responsible for ion BONE the new virtual machine now.

Sorry if this has been asked somewhere else. I tried to find the answer but am still confused.
If I have a virtual host 24 hearts with 3 under VMs.
I guess the best way to ask my question by describing two hypothetical scenarios.
Scenario 1: I assign 1 virtual kernel for each machine.
Scenario 2: I assign 8 Virtual cores for each machine.
Each VM will have more CPU power in scenario 2? Now, my assumption is that each virtual machine will be allocated 33% of the CPU in both scenarios, but I fear that scenario #1 will leave a lot of unused CPU power.
Thank you.
If I understand correctly, in other words, the amount of GHz... MHz... etc available to VMS is based on the value of the shares, so, based on your two scenarios, each will have 33 percent of the shares. Performance of virtual machines depends on how applications behave in MP. VMs CPU scheduling also changes with the number of vCPUs configured.
Testing is the best way to answer this question.

Greetings,
I improved my esxi U1 5.0 to 5.1 and attempted to create a new virtual machine in hopes of using the new version of material 9.
Using the standard and Custom options I been unable to create a Version 9 hardware VM by default.
The only option I had was manually upgrade to version 9 once the virtual machine was created.
Any thought or is - this as planned? I need to reinstall from scratch, my host?
dhayashi
To create virtual machines with HW version 9, you can use the Web Client, rather than the windows based Client vSphere.

Create subfolder under virtual &; model computers
I like the script to create folders for Virtual Machines and the model display. To the i in this moment completely chaos.
This code makes it easy as a starting point.
But if I create subfolders that whenever the message folder already exists appears as a red event.
root folder / sub-folder / under file / under folder / sub-folder
Main record office

Server main folder
DC/location/environment/infrastructure/server/departments01

I did a PowerCLI-New-BlueFolderByPath function, allowing you to create folders for you. You must specify the path to the full in the service folder, as you can see in the example. The function will create all the folders (sub-) that do not already exist.

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

I'm new to PowerCLI and find quite simple, but in the documentation I read, I don't see how to use a virtual hard drive, existing on a data store when you create a new virtual machine.
Is this simple registration on the virtual hard disk, or did I miss something?
My current create VM is the following statement:
New-VM
-Name $TargetHostName -host $TargetVMCenterHost -data store $TargetVMCenterDatastore DiskMB - 20000 -MemoryMB $TargetHostMemoryMB -NumCPU $TargetHostCPUs -ID $TargetHostOS -CD -Description $TargetHostName
Didn't notice this before, but I think that vSphere will use a backslash instead of a slash in the paths.

Create the new virtual machine using Java API vCloud
Hi guys,.
I am trying to create the new virtual machine in TIME, but I've stuck here. The API I'm using is vcloud-java-sdk - 1.0.jar.
Could you please show me a code snippet how to do this?
For now I do it like this:
RecomposeVAppParamsType recomposeVAppParamsType = new RecomposeVAppParamsType();
List the items < CompositionItemParamType > = recomposeVAppParamsType.getItem ();
ReferenceType vappTemplateVMRef = new ReferenceType();// ??? seems that new reference to the new virtual machine should be here. But how to create this VM
CompositionItemParamType compositionItemParamType = new CompositionItemParamType();
compositionItemParamType.setSource (vappTemplateVMRef);Items.Add (compositionItemParamType);
ReferenceType vAppRef is Vdc.getVdcByReference (vcloudClient, vdcRef) .getVappRefByName ("vApp_Websrv");.Vapp.getVappByReference (vcloudClient, vAppRef) .recomposeVapp (recomposeVAppParamsType);
One day before I played with Web Services SDK, which is much easier to understand. I was able to create the vApp and VMs in vSphere. Is it possible to import machines virtual vSphere to vCloud? Should what API I use for this?
Thank you
Hello
You cannot add a new empty virtual machine in a paralytic.
Instead, you can add a virtual machine from an existing vapp, vapptemplate.
To import a vsphere vm to vcloud.
Import vsphere vm as VAPP in vcloud. VMWVimserver-> importVmAsVApp()
The importation of vsphere vm, as vAppTemplate, in vcloud. VMWVimserver-> importVmAsVAppTemplate()
See also the example of ImportVmAsvAppTemplate.java, which is part of the vcloudjavasdk group.
Kind regards

VCLI orders are mainly used for configurations of the host, although as part of the installation of vCLI, you get also vSphere SDK for utilities Perl - http://www.vmware.com/support/developer/viperltoolkit/viperl41/doc/vsperl_util_index.html that provide additional canned scripts, which allows you to create a single set of virtual machines using the vmcreate.pl script. There is an example on how to use a script

HDD USB not recognized as "physical1" when creating the new virtual machine
Hi all
I wanted to create a new virtual machine, and I wanted to use my USB as a physical drive.
But Workstation shows me "physical0" which is of course my drive internal.
I tried USB pen drives. They are not recognized either.
This somehow is no longer supported? I would have that it would be possible to use USB external HDD as the physical drive to a new virtual machine.
you have installed VirtualBox?
If so, you can try to use the virtuaklbox command line tool to create a descriptor of rawdisk for this disc.
say diskpart on this drive? -It is "online"?

Error during communication with the remote host when you create the new virtual machine
I'm under 7 ESX servers on IBM Blade H22 there is a mistake to invite while I create a new virtual machine
on the vcenter Server
At the end of 30-35 minutes, it gives an error
"Error during communication with the remote host"
The existing machines are working well... I tried to create virtual machines to other ESX servers as well
but the same question. I also tried to make the clone of existing machines, but without success
Can anyone help?
You rescan the LUNS once?
You've restarted the management agent?
You've restarted the vpxa?
If this isn't the case, please perform the step above and check out them.

I can't create a new virtual machine, for the error "invalid state" of vmware
Hi, I have an esx server with some production virtual machines vmware;
Yestarday I made a new VM, suse linux, froma cdrom; but the file system broke down, it has been altered, I don't know why,
and I had to cancel the machine using the "remove disc";
After that I could read "a system general error occurred" and when I click on create a new virtual machine (ctrl + n), I can't because the answer is "invalid state".
When I click on each virtual machine in 'events', I do not see the logs, I see this error "system general error occurred.
can someone help me? , should I restart the service mgmt-vmware? (init.d) on the host server?
Thanks in advance, best regards

If you use Virtual Center, rebbot VC server and try again. If this does not work, you may have to restart the ESX host.
