• Reservations on each virtual machine

  Why is it a bad idea to have reserves of CPU and memory on each virtual machine in a cluster? I'm trying to find more information. This is a good answer. I would be grateful if anyone can provide additional information on this topic.

  Setting memory reservation affect the virtual machine and its surroundings. Definition of reservation by virtual computer is not recommended; It is advisable to create pools of resources instead of by M V reservations. Reservations of setting at a granular level leads to an increase in administrative costs and operational overhead. But when the situation requires to use a booking of VM, how a reservation is adjustable to ensure performance as well as possible without losing the physical memory and also less impact as possible. The answer: define a reservation equal to use memory average of VMS comments.

  Pasted from <http://frankdenneman.nl/2009/12/08/impact-of-memory-reservation/>

  Reservation on each machine virtual is a bad idea because you are guaranteeing resources to guest, regardless of usage.

  For example. You guarantee 4 GB of RAM to a virtual computer, but using only 2 GB, 2 GB of physical RAM that could be used by other virtual machines running in this case you lose.

  It's a good idea in case you know the use of the virtual machine is high and it would take resources guaranteed to continue to work effectively

• CPU on each virtual machine

  Hello

  is that what everybody knows on the calculation in cpu on each virtual machine?

  There are 2 cpu configuration section

  1. virtual Socket number

  2. number of per-socket basis

  and the total number is = 1 * 2

  I want to know if I installed a windows 2012 with standard license that supports the core 64 on a virtual machine

  then set the virtual socket number to 4 and the number of base by socket to 4 the total number of base become = 16

  Windows recognizes this as the core? and it works with that because it supports the core 64?

  or not? It recognizes the slot as a new processor and install 4 cpu and it does not install or update...?

  Thank you

  This will give you a very good understanding on it

• How to add the AD security group in each virtual machine with a name corresponding in VCenter?

  Hi all

  I would like to know if it is possible with VMware PowerCLI v4.1, I created the universal security group called 'Local administrators on %ComputerName%' for each server I have in UO computers by location OR separate and that he manually add members of the Local, but I want to attribute this security group in each computer virtual with the same name if possible.

  Basically, it's something like this:

  In the ad, here are computer objects:
  DOMAIN.com/Computers/ mailserver1-VM
  DOMAIN.com/Computers/ DBServer1-VM
  DOMAIN.com/Computers/ ApplicationServer1-VM

  In the ad's local security group objects:
  DOMAIN.com/SecureProductionOU/ 'Administrator locally on mailserver1-VM'
  DOMAIN.com/SecureProductionOU/ 'Local on DBServer1-VM administrator.
  DOMAIN.com/SecureProductionOU/ 'Local on ApplicationServer1-VM administrator.

  So I want to affect these security group in each respective name of VMS in VCenter:

  VCenter01.domain.com
  Datacenter1
  HighPerformanceCluster1
  Mailserver1-VM - Local Administrator on mailserver1-VM - role: read-only
  DBServer1-VM - Local Administrator on DBServer1-VM - role: read-only
  ApplicationServer1-VM - Local Administrator on ApplicationServer1-VM - role: read-only

  Any kind of aid and assistance would be appreciated grgeatly.

  Thank you.

  Hi Albert,

  I don't know what you want to check exactly, so I give 2 possible solutions.

  (1) you have a fixed number of names known to virtual machines for which you want to add this permission.

  $targetVM = "MailServer1-VM","DBServer1-VM","ApplicationServer1-VM"
  
  Get-Cluster -Name HighPerformanceCluster1 | Get-VM | `    where {$targetVM -contains $_.Name} | %{    New-VIPermission -Entity $_ -Principal ("DOMAIN\Local Administrator on " + $_.Name) `       -Role (Get-VIRole -Name ReadOnly) -Confirm:$false   }
  

  (2) you want to check for each virtual computer if the security group exist and then add the authorization.

  Get-Cluster -Name HighPerformanceCluster1 | Get-VM | `    Where{Get-QADObject ("DOMAIN\Local Administrator on " + $_.Name) `        -DontUseDefaultIncludedProperties -WarningAction SilentlyContinue `        -ErrorAction SilentlyContinue -SizeLimit 1} | %{    New-VIPermission -Entity $_ -Principal ("DOMAIN\Local Administrator on " + $_.Name) `        -Role (Get-VIRole -Name ReadOnly) -Confirm:$false} 
  

  Note that this requires the Quest AD snap-in must be installed. If you have a version without the Quest AD snap let me know.

• Statement on the date of a virtual machine has been created

  Is it possible to report on the date on which a virtual machine was created?  This info is stored anywhere with the virtual machine?  Otherwise, he'll find newspapers in VMware Server to say how many virtual machines have been created last year?

  Thank you

  The Get-VIEvent cmdlet gets its information from the database of vCenter. To be more precise in the VPX_EVENT table. You can only return in time with respect to the first record in this table. To retrieve this date, you can use the following code:

  $eventMgr = Get-View EventManager
  $filter = New-Object VMware.Vim.EventFilterSpec
  $eventCollector = Get-View ($eventMgr.CreateCollectorForEvents($filter))
  $eventCollector.RewindCollector | Out-Null
  $eventCollection = $eventCollector.ReadNextEvents(1)
  $eventCollection[0].createdTime
  $eventCollector.DestroyCollector()
  

  The downside to the use of the Get-VIEvent cmdlet is that you must specify the number of records to be returned (100 by default) with the - MaxSamples parameter, and all these records are retrieved from the database. If you find events and you don't have a period, you must provide enough samples to include yours, and it can last forever. The event table can grow very large. In my environment, there are 8 million + records in this table.

  For the search of the database of events, I prefer to use the SDK instead of the Get-VIEvent cmdlet. That way I can start research until my records are found, and I can use specific filters to retrieve only the records that are of interest. I also pick up only as many records of the database if necessary. You can search the crΘation from a virtual computer by using the code below:

  $vm = Get-VM "myVM"
  
  $eventNumber = 100
  $eventMgr = Get-View EventManager
  
  $filter = New-Object VMware.Vim.EventFilterSpec
  $filter.Entity = New-Object VMware.Vim.EventFilterSpecByEntity
  $filter.Entity.Entity = $vm.ExtensionData.MoRef
  $filter.EventTypeId = "vim.event.VmCreatedEvent","vim.event.VmClonedEvent","vim.event.VmDeployedEvent"
  
  $eventCollector = Get-View ($eventMgr.CreateCollectorForEvents($filter))
  $eventCollector.RewindCollector | Out-Null
  $eventCollection = $eventCollector.ReadNextEvents($eventNumber)
  $matches=@()
  While ($eventCollection) {
    $matches += $eventCollection
    $eventCollection = $eventCollector.ReadNextEvents($eventNumber)
  }
  $eventCollector.DestroyCollector()
  $matches
  

  See you soon,.

• How to access files in a folder to store data for a virtual machine?

  Hi all

  I'm relatively new to virtualization in general (I'm learning!) and have a question.  I have a host server of VMware ESXi 5.0 set in place with several VMs configured in it.  I also have various data stores configured, usually a virtual computer by the data store.  Most of the virtual machines are Windows, but one I have problems with is a machine virtual 64-bit Red Hat Enterprise Linux (RHEL) 6.  I currently manage and administer the server remotely over a slow connection.  Anticipate, the last time I was on the same network as the host server, I downloaded to a folder on the same database as the VM RHEL, about 5 GB of files that I knew that I would need to access in the VM RHEL install different software.  Now, I'm trying to "expose" these files very to the RHEL VM so I can install the software.  How would I do that?

  From what I've gathered reading other posts here, I could create an ISO that contains the files and then upload that to the server on the host to be mounted into the CD player, but my connection is so slow that would take a very long time.  I also believe that I could create a network share on my Windows 7 computer and allow the virtual machine to access the files in this way - but once again, my connection is the problem (not to mention that I do not have a GUI installed on RHEL and I'm not a Linux expert).

  None of the files I need are ISOs, unfortunately, so I can not directly mount the CD-ROM drive in the virtual computer from the data store.  If I have access to a shell on the host server, it does not recognize the command vmware-mount so I can't access the virtual disk for RHEL to just copy the files into it.  Also, it does not recognize the mkisofs command (of which i google trying to figure out if I could create the ISO on the host itself).

  So, basically, I'm looking for a way to access files in a virtual machine that are in the same bank data, as its virtual disk.  If that is possible to copy these files in virtual drive somehow, or mount a CD-ROM drive or hard drive that exposes these files on the virtual computer, I don't have a preference...  I'm just trying to not have to re - download the files in a different format (or using a different method) since they are already on the host server.

  Any suggestions would be very appreciated that - thank you.

  Welcome to the community,

  one solution might be to enable SSH on the host computer and then use scp to access or download files from the host/datastore (within the Linux VM).

• How can I assign a static ip for each virtual machine

  I have the NIC 2 and 3 vm on my vm server.

  I did find documentation how to assign an ip for each virtual computer fix.

  pleas help me... but probably easy...

  Assuming you have the management and the virtual machines on the same network, attach both rising/NIC bindings to the vSwitch0, configure the management network and tie each VM to the port "VM Network" group. As DSTAVERT mentioned, the IP of the virtual machine configuration is done in the VM themselves, as if they were physical systems.

  sample:

  

  If you have different subnets for the management and the virtual machines, you must either create multiple vSwitches or work with the VLAN.

• Upgrade to 5.1 constantly cause 'snapshot of disk space' enabled on each virtual machine

  Hello
  Since our upgrade from 5.0 to 5.1 all my virtual machines get alarms for "Flash disk space" even if none of them have any pictures taken. Even after acknowledge, and clear all alarms it will return.
  It also triggered the alarm directly after I deployed a new virtual machine from a template.
  I have not upgraded VMware tools on any of these virtual machines at the moment.

  Anyone else encounter this problem and might have a solution.

  Others just going to have to revisit VMware the phone since this flood of our mailbox to support at this time with false alarms.

  Thank you

• After an upgrade to ESXi 5.0, 5.1, my virtual machines are not listed in vSphere.

  The directory structure still seems to be on the disk.  Is there an easy way to get vSphere to recognize?

  Welcome to the community,

  I guess you Install accidentally selected rather than upgrade! Anyway, you can just browse the data store and do a right-click on the .vmx file each VM to add the virtual machine to inventory.

• How to get the status of data for each virtual [identify overprovisioning] computer store?

  Hi people,

  Could help me is it you please in the generation of report of VM and its data store location (data stocker store free space, size set up and operation). ?

  Try this:

  Get-VM | Select Name, @{N="vSwitch";E={Get-VirtualSwitch -VM $_}} | Sort Name
  

  Or if you want to trade as well:

  Get-VM | Select Name, @{N="vSwitch";E={Get-VirtualSwitch -VM $_}}, @{N="PortGroup";E={Get-VirtualPortGroup -VM $_}} | Sort Name

• Script in time of latency list vm e/s and the data store the virtual machine is on

  Hello.  We have a vsphere 5.0 environment and we live a latency of IO heavy.  I'm looking for powercli script will get the latency of i/o for each virtual machine and get the data store name, to what it is now.  We will access our storage on optical fiber.  I'm trying to get a good overview of the latency of IO in a nice view in a csv file.  I found what could be a good basis to https://communities.vmware.com/thread/304827?start=0 & tstart = 0 , but I'm not sure how to get the name of the data store in the table and I think that it is written to the nfs in any case storage.  Thanks in advance for any info\advice!

  Try the next version, it includes the average latency time read/write for the virtual machine and PAHO are / s average for the virtual machine.

  Since the CSV has a row for each data store, the values for the virtual machine are repeated.

  I also added the host name

• What is the advantage to affect multiple virtual machines in a data store?

  Hello

  Quite a question stupid and basic, but I can't answer . What is the advantage of having multiple virtual machines in a store of VMFS data instead of having each VM in another VMFS data store? (eg. 3 VMs in 1 data store or 3 data warehouses and each virtual machine in one of them). I can only think about the ease of management for storage administrator because it creates only a single large LUN.
  
  Thank you

  By allowing multiple virtual machines in a data store, you can run more than 256 virtual machines in a DRS cluster.

  As a host has a limit of 256 scsi identification numbers, which means that it accesses no more than 255 LUNS shared. 1 scsi ID is used for local storage.

  In a DRS cluster as each host must be mapped to the same data warehouses to ensure that virtual machines can be moved on the cluster and run on any of the hosts.

  Now in my life as an architect VMware PSO I saw that a lot of virtual machines that require a single data store. The main reason to isolate a virtual machine on a data store must provide sufficient i/o performance. This can be achieved with other solutions than to isolate a virtual machine on a data store. Having a properly architected storage subsystem is crucial, vSphere can get out of a very large number of the IOPS / s. With technologies such as SIOC and DRS for storage, you can check that the virtual machines receive IO performance according to the needs.

• What is the best way to backup of virtual machines on a standalone ESX with the data store local

  Hello

  I want to save the virtual machines on a host ESX autonomous. and all of these virtual machines is the local data store.  What is the best way to save these virtual machines in this situation?

  And probably we don't provision VTL on the local data center, so it is possible to use VCB to backup? And VCB is a good choice compared to the traditional method that installs the backup client in each virtual machine?   Because I think that in this situation with the data store local, it cannot not reduced the load on ESX hosts and network overhead can be avoided.

  Thank you!

  LAN

  > 1. VCB usable remote tape library? I mean it's not local library and uses the tape library to another network data center.

  VCB is completely unrelated to the tape library, it is a framework, not a backup solution. If your standard backup software can work with the remote tape library you can try it to ungrateful with VCB.

  > 2. what the difference bwteen hot - added NBD and modes if there is that an ESX host with store data local and want to use a virtual machine like VCB proxy? I think that they are the same: the VCB proxy read data through the I/O of the ESX host stack in this situation.

  NBD works on network and the backup traffic goes through the service console connection. Hot add uses special machine for assistance to connect vmdk to and uses of e/s disk stack instead of e/s network.

  > 3. Veeam Backup is free software?

  No, it isn't.

• Is it possible under the EULA to have several virtual machines on a single physical hard disk while using the same OS license or do I need a separate license for each virtual computer?

  I have several programs that are not compatible with my 64 bit Windows 7 operating system.  I would like to run each different software under another virtual machine of VMWare (5 packs of different software programs and 5 different virtual machines of Windows XP).  These would all be installed on your laptop.  I can use the same license of Windows XP for each virtual machine, or do I need a separate XP license for each (different XP in case 5 licenses)?

  It is lifted directly from my EULA:

  1. GRANT OF LICENSE.

  The manufacturer that you grant the following rights, provided that

  comply you with all terms and conditions of this EULA:

  1.1 installation and use.  You may install, use, access,

  display and run one copy of the SOFTWARE on

  THE COMPUTER.  The SOFTWARE may not be used

  by more than two 2-processor both on the

  COMPUTER, unless a greater number is

  indicated on the certificate of authenticity.
  Then...
  This means that as long as you are running two or more instances of XP at the same TIME, you agree? Or does this mean that, after you install once, you have reached your limit?
  I imagine that most people (including those who are running Microsoft!) will say that the second interpretation is correct.
  However...
  If this is the case, anyone their hard drive as a backup to clone strategy would violate the EULA!
