• You can enable CDP on a host with virtual machines running?

  I want to activate CDP on my 3 hosts vShpere 4.1. Each host has about 20 guests on this subject. If I activate CDP via putty will affect the network connectivity of the virtual machines running on the vSwitch? Can I move all the VMS hospitality first?

  Hi Letstub,

  There is no need to evacuate your virtual machines from the vSwitch. Enable or disable CDP has no impact on the communications of the network of virtual machines. The following article that explains how to enable CDP mentions this prerequisite:

• Compare with virtual machines running VMs

  So, recently, we had a major problem in our environment where a ton of virtual machines registered of VC and even became unmaged by facilitators, so we had to go to each host compare managed virtual machines running virtual machines.  Is there a way to do this in Powershell?  My brain is fried so I didn't have much luck.  Thank you!

  Could the script in this post, HowTo find all VMX files in all data warehouses and store them in VC?, maybe help you?

• cannot select store with virtual machine

  Hello

  I want to configure RDM for a virtual machine that has been powered down. When I chose one to add a ROW to a READ, the "Store with virtual machine" option is grayed out, only 'Specifies the data store' is available. From what I had experienced, by specifying a data store (only the local data store unavailable to its host), this would avoid this VM vmotion when its current host has been disconnected.

  Please correct me if I'm wrong, but what is the reason for which a virtual machine would not be able to choose la carte READ my San to his record?

• Impossible to reconnect to a virtual machine running

  Hello

  I removed decadent a virtual machine running in the inventory.

  The machine virtual is critical and cannot be stopped.

  When I try to browse the data store the option "add to the inventory" is grayed out.

  How can I reconnect it to the inventory?

  Thank you

  Alternatively, you can try to reboot the virtual machine in vCenter:

  1 vim - cmd vmsvc/getallvms

  2 vim - cmd vmsvc/reload xx
  (xx is the VMID provided by the first command)

• Virtual machine running on snapshot but there are no spanpshot on the Snapshot Manager.

  Hi all,

  After a backup with VMware Data Recovery failure (error-3960 cannot suspend virtual machine), I have a virtual machine running on snapshot (see attachment) but there is no snapshot on the Snapshot Manager. Is the command to "consolidate" (I have never used this feature) the solution?

  Thank you.

  Marco.

  OK let me explain.

  As the chain of snapshot is not displayed in snapshot Manager, you can correct this problem in two ways.

  1 engage the snapshot command line. If you are uncomfortable in the command line, follow this KB KB VMware: commit snapshots on ESXi host command line if you are not comfortable follow step 2.

  2. create a new snapshot for this virtual machine (this will create a chain of snapshot, and you can see the snapshot in the Snapshot Manager), once the snapshot is created successfully. You can remove the snapshot in the Snapshot Manager.

  Hope this is clear. Let me know if not

• Large SQL virtual machines running on ESXi

  Hello

  When you decide to run or do not run large SQL VMs on ESXi, what are the points that you take into consideration?

  -How much memory physical RAM more should the ESXi host at least have in relation to the virtual machine? If I have a Go 96 VM on a host of 144 GB, you would use this room for other virtual machines as well? Would you go to bigger hosts? Or that you would a one-VM-host?

  -In a "a virtual machine by host" scenario, is there still a sufficient reasons to virtualize the VM? VMotion, the portability of the virtual machine, adding disks, disks, resizing easy resize memory still reason enough to virtualize this VM?

  -When I add now Microsoft clustering in the equation, killing VMotion and flexibility, it is always possible to virtualize this SQL Server?

  I know how capable ESXi is the delivery of this workload. I have the white papers of performance on HOW to virtualize SQL successfully. My question is above all on: If you...

  It is like arguing about policy; There are people with all kinds of views and a large part of it boils down to personal opinions. Some things to consider;

  (1) you do not mention how CRITICISM (aversion to downtime) is the database. If it is super important, certainly looking to HA or even fault tolerance. This increases considerably resources on a virtual machine.

  (2) even if you use one approach "a virtual machine by host", you must make sure that the availability on OTHER hosts in the case where HA is triggered.  So you have basically two hosts per VM

  (3) in view of the above, and how this intensifies that you get in redundancy, HA and FT, you can compare the cost a cluster HA environment.

  We personally, it is facing a prior work. We went with material in the physical server cluster.  In my opinion, if the server is simply great, but didn't need to HA or FT, then I would consider virtualization it. If she needs these features, the fresh material support worsen significantly. Size alone is not a huge problem, assuming you have the SAN space or storage. I am currently supports environments with virtual machines that are more than 1 TB and will work perfectly.

  I hope this helps.

• All virtual machines running on ESXi 5.1 statement of Rx packet loss

  Can some of you please do me a favor? Find a virtual machine of yours running on ESXi 5.1, preferably 1117900 and let me know if you see a Rx packet loss in performance stats vCenter provides. Each single VM in my environment records packet loss. Virtual machines running on ESXi 5.0 are not related that at all. This also isn't a problem at the level of the host that there is no loss of package noted it.

• List of Cluster and the virtual machines running on this group

  Hello

  I am looking for a way to discover all of the virtual machines that belong to a cluster. In other words, I want a list that maps a cluster to all virtual machines running on it.

  In the documentation of the API, I find that "ClousterComputeResouce"has a managed object to "HostSystem" reference. "

  And "HostSystem" is a reference to managed object to the 'VirtualMachine'.

  So I can do it like this: ClusterComputeResource-> ManagedObjectRefence-> ManagedObjectRefence (VirtualMachine)-> whatever_properties_I_need_from_the_VM (HostSystem).

  However, this would cause a lot of ' Vim::get_views"calls within a"foreach"loop." It would be a deterrent to performance as the vCetner in question has ~ 50 clusters and has ~ 3500 running VMs.

  I think this was going to literally kill the VirtualCenter with so many API calls.

  My Question: is there an effective way to find Cluster and their respective VMs in vSphere SDK Perl.

  In vSphere client, we get the tab 'Virtual Machine' when we click on the Cluster and you can see all the virtual machines that belong to this cluster. So I hope that there must be an easier way.

  Thank you.

  Hello

  You don't need the host_view for this action. Why don't you use begin_entity for views of the vm?

  my $cluster = 'cluster1. "

  My $cluster_view = Vim::find_entity_view (view_type-online 'ClusterComputeResource',

  filter => {"name"-online qr / ^ $cluster / I});
  {if ($cluster_view)}
  My $vm_views = Vim::find_entity_views (view_type-online 'VirtualMachine',

  begin_entity => $cluster_view.

  Properties-online ['name']);
  foreach {$vm_ref(@$vm_views) my
  print $vm_ref--> name. » \n » ;
  }
  }

  Hope that helps!

• Virtual machines, run extremely slow when the console is consulted 2 virtual machines Windows Server 2008 64-bit, Windows Server 2003 32-bit, 2 VMWare for virtual machine

  I'm in a difficult situtaition here.  I am the daily contact with a new client.  My linux guy, who is also my boss who is very busy, asked me to do some research trying to find answers for what's not on this server. We have a dual Quad Core 2.5 Ghz Lenovo server with 10 GB of ram.  2 500 GB hard drives are Raid 1.  We run Virtual Server VMWare 2 on a Debian with Gnome installation as a user interface for the side of things Linux.  Grub is the boot loader. There are two virtual machines running on the server.  The one machine that serves as a domain controller is a Windows SBS 2008 Server 64 bit, and the secondary machine has no responsibility domain.  The second machine is a Windows Server 2003 32-bit.  the 10 GB of ram 6 GB is allocated to the SBS server and 4 GB to the 2003 server.

  The problem I am running into is that everything is so slow, especially if I connect remotely to do any sort of administration on the network.  Some examples of issues I've noticed is that as soon as I log on the server via Remote Desktop SBS console management Windows Server spike to 80-95% CPU usage and it will not stop unless I close the management console.  Another instance is that if I open Backup Exec 12.5 on the SBS server it will kill the speed of the processor as well.  Long story short, there are a lot of machine to do what we need to do, but something is not configured right and non of us know what it is.  Another point to note is that the server has been in production for about 3 weeks, and the server seemed to have locked up just twice.  My professional guess is that over time, some chose thing is eating causing the crash of the memory.

  Sorry I do not have much technical insight on this topic, but this is the best I have to offer.  Any questions you all have, I'll ask my people and see if I can answer, but I could really use your help here.

  Thank you in advance,

  Heath

  2 things:

  1 you really need hard drives more than 2 in a RAID 1 for proper performance under load. More disks the better. Although I don't think that's what your problem is, he'll probably be the problem Next you will do.

  2. I don't know exactly where the configuration file is on your box of Debian for VMware Server, but you should consider adding the following options in the configuration file (on windows, it's the vmware 'config.ini'):

  prefvmx.minVmMemPct = "100".

  MemTrimRate = 0

  sched.mem.pshare.Enable = "FALSE".

  mainMem.useNamedFile = "FALSE".

  If you do some research, you can read about what these options (the largest is the memory page sharing - it should only be left on if you have a bunch of similar virtual machines running on the same box, that you don't have.) I honestly know why this is on by default, he kills the CPU when virtual machines are running different operating systems). These are the options that I now use standard in VMware Server deployments, with huge performance increases after you have added the. Just give a try.

  Edit: Also make sure that you have installed in your virtual machines VMware tools.

• Move the server vCenter as virtual machine

  Hello

  I was asked to spend 5.1 vCenter virtual from one cluster to another. I guess that would not big problem, but there is a situation.

  vCenter server 5.1 is sitting on one of the hosts in Group A here is the IBM hosts with AMD processors. I have to move to group B which has HP hosts and Intel processor. This means that I have to close vCenter server to move, but at this stage I am lose the connection to the vCenter server.

  How to move this server to another cluster. vSphere client is out of the question, but also web interface. I guess that some sort of command line should work, but I don't know how

  All ideas

  Thank you very much

  In this situation, there are several options.   All of them require vcenter would fall at some point.

  1 use of vsphere replication to replicate the vm and then stop and start

  2. use converted for vcenter convert and more (you need to turn off the virtual machine to get a clean snap)

  3 use SCP from one host to another

  4 vmotion the VMS to shared storage that can see the two hosts, turn it off remove inventory in one add B and power on

  I don't know there are methods more I do 4 If you can.

  Thank you

• How to migrate from vCenter as virtual machine to another host without vMotion running

  We organize ESX 3.5 hosts. I've already updated our vCenter VM to 4.0U1. We have not the vMotion Installer yet (but are licensed for her). What is the appropriate way for migrating the vCenter VM to another host without vMotion, so I can upgrade the host the vCenter VM is running on? I have examined all the documents and messages, I could find, but don't have not seen this addressed.

  You must turn off the virtual machine.

  Copy the files (if are not on a shared data store).

  Save the vmx file in the new ESX (with browser data store).

  Turn on the virtual machine.

• In the virtual machine running to vCenter

  Hi all

  We plan to install vcenter in a virtual machine. It will be connected to a SQL Server that will also be a virtual machine.

  Everything is looking for attractive about this config but we have some questions about VUM and other patches and upgrade which will take place.

  My question are as follows:

  -If the vCenter and AUVs are virtual, what will happen during a deployment of patches for these servers?

  -Si SQL is also virtual, what will happen during the correction of the virtual server?

  Thanks in advance for any suggestion or answer

  Michel

  Uh, excuse me, but I can't quite follow your 2 questions.

  Execution of vCenter with VUM in a virtual machine is a fully supported configuration where you can enjoy features such as HA for increased availability, instant etc..

  I'm running a vCenter virtual with VUM and other optional packages of a virtual machine, 8 host management and 130 machines virtual too without any problems.

  This guide is for vCenter 2.x, apply but to 4.x for the most part too: http://www.vmware.com/pdf/vi3_vc_in_vm.pdf

• Trouble using NI USB-4065 with virtual machine VMWare

  Hello

  I'll be working with a virtual machine (windows xp) and I need to use an NI USB-4065 DMM.

  When I connect the USB-4065 to the PC, the virtual windows xp recognizes the new HW and also MAX display the new device on the list DAQmx.

  It seems ok, but if I try to use the USB-4065 (open the soft cover or in a LabView VI), the device does not work.

  If I use the frontpanel app, when I click a botton, the Group seems to work but doesn't measure anything; If I try to reboot the softpanel, it works and 'freeze' of the screen.

  If I use LabView, the VI returns an error on a maximum duration of the measure.

  I'm trying to use the device on the real machine (not with VMware) USB-4065 works, whith flexible Panel and whith VI.

  I update the driver of the DMM on the virtual machine, beats the device still doesn't work.

  ... I don't have any other idea, can anyone help me with this problem?

  Thanks, SEM.

• Only don't have a permit no cd! How to install a virtual PC with virtual machine? :(

  I got a computer with windows xp Pro and I lost to a virus. And I got a windows 7 that was unused, so I installed it and now I'm wondering. Can I continue to use the Pro license (and my windows 7 had a new virus so I did reinstall windows 7 and activated it right.) But then he broke again while I did the same thing and this time she didn't so I called and I was connected with 5 people and the 5th person fixed my license for the last time for free! Thank you microsoft! ;D )? And I can't find the cd for pro! And I tend to use the license and however you can get the installation to work without the disc on the virtual machine that you have made. PS I also say that I have the license but not the disk. What should I do?  DX

  Hi Alexander,.

  ·         Using Windows XP on the virtual machine?

  ·         What version of Windows 7 you have installed?

  If you plan to install Windows XP separately and have the dual-boot Windows XP and Windows 7, you must have a Windows XP disc. You can see the following link for more information.

  How to replace Microsoft software or hardware, order service packs and replace product manuals

  If this is not enough, you can install Windows XP on Windows 7 using Virtual PC, unless you have one of the following editions of Windows 7 (Professional, Ultimate or Enterprise). This does not need to have the Windows XP disk.
