• Extend a datastore in vCenter with virtual machines running

  We have expanded our Volume and unit number logic on our NetApp SATA VMStore from 2 TB to 4 TB, we now want to expand in vCenter, I'm ok to do this within office hours, while VMS are running on the data store?

  Going via configuration - storage - etc etc...

  It should be good. Off-peak hours are preferable, because you must make playback etc.

  This will not affect the virtual machine running inside.

  Unless there is a particular requirement, why not go with 2 TB Lun? I mean add another 2 TB logical unit number rather than add a measure?

• 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

  Boaz

  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

• 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 » ;

• 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:

• 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.

• 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?

• Maintenance mode migrates virtual machines only from GUI

  We have 6 * 5.1 with configured ESXi HA, DRS and a 5.1 Vcenter.

  If we put an ESXi in maintenance mode through the user interface of Vcenter all virtual machines will be to migrate to other hosts, there is no problem at all.

  But if we put the same through VMA host in maintenance mode, virtual machines will suspend mode and the host goes into maintenance mode. On the GUI in Vcenter we get a message that a migration will not work in the current state. Due to the fact that the message is in German, there's not so much sence to post it here, I guess.

  Background is, we have two or three guests time in different places. Two locations in separate buildings, with separate power supply and separate UDP for this purpose.

  So if a location powerd down the udp Protocol must stop the hosts in this place and the virtual machines have to migrate over.

  SVMotion is not necessary, the SAN is a unit of mirroring automatc.

  Please take a look at Re: scripted Maintenance Mode to see if that helps.

• Two guests of virtual machine running in Bridge Mode connection question

  Hello

  I seem to be a little lost with a problem.  What I've read, VMWare Server is free (I plan to use it in a test environment, which is low-budget).  I installed on a server and got two VMGuests of installation at the moment.  The question I have is that I don't see the first guest that I boot on the network at any time? Anyone who encountered this?  that is, if I start the server A and Server B then, Server A is located on the network without problem but can't change anything to or from Server B.  If I stopped server server B still does not work.  If I stop the server B and then start up with the server still does not, it will work on the network.

  At first, I thought that because it's free it will allow only one server at once, but I don't think it's true.  The only other thing I can possibly think, is that I just copied a basic virtual machine Image I created so that both servers are at the same image.  When asked if I had copied from moved it I chose move, this might be the reason, and I need to select copied?

  Anyone got any ideas please?

  Kind regards

  Wayne

  Looking for a line like the following, with a text editor in the file .vmx for each of your virtual machines:

  ethernet0.generatedAddress = "00: 0C: 29:b2:04:03.

  There may be several entries being Ethernet if you have multiple network cards. That's how the MAC address is set and must match what ' ipconfig/all' or 'ifconfig - a' shows you in this prompt.

  MAC addresses are not totally free but you can manually change the lowest few bytes (for example the 03 to 05 in the example above) or a more correct way is to add another NETWORK card and then delete the original, a copy.

  When you reach the point of having the 'model' virtual machines - where you copy the files manually to a new location to create a new virtual machine - and then add the following line to the .vmx to avoid this problem doesn't happen:

  UUID.action = "crΘer".

  You want "cloud." If you have heard of the interest of the industry in the "cloud computing", it's an aspect of it. You create a virtual machine and hand it turns off your COMPUTER service (for a private cloud) or a hosting company (for a public cloud) and don't have to worry about the maintenance of the equipment. See also http://www.vmware.com/solutions/cloud-computing/

  Cloud computing market is still fairly new, and there is no I'm aware of many suppliers. I also expect them to focus on business first rather than individuals, as businesses will be probably easier to bear (homogeneity) and are willing to pay more.

  As others have said, the current accommodation market (which IMO offers only a fraction of the capabilities of a cloud) is mostly about getting a generic instance and tweak to your liking. I guess the underlying architecture of most of the places is a strategy of container - like - this can reach higher densities (because resources from reviews are shared) at the expense of the flexibility (because resources from reviews are shared), but maybe not what you want.

  The only currently existing service on a large scale that allows the download I can think of off the top of my head is Amazon EC2 (which is a strategy of container and not based on VMware products). You are limited to a certain list of grain and the capabilities of the resources and of course must be in their specific file format.

  If you're ready to be your own host, or can find a small hosting provider, Fusion VMS should be able to run on vSphere with minimal changes (vSphere companies target, so it is much more interested in the most characteristic stability.) Some features that work in Fusion do not work on vSphere).

• Monitoring of virtual machines running on the UCS blades

  We are in the process of migration of servers HP rack to Cisco UCS blades. I have 4 blades UCS running ESXi and dΘmarrez from SAN. We have configured in HP SIM HP servers to monitor hardware issues and the status of the VM. Now Let's watch the material of the UCS in UCS Manager, but I still need to monitor the status of virtual machines. I looked at existing Solarwinds NPM we have all our ESXi HP servers to Solarwinds. What I've discovered, is that we cannot add the individual to NPM ESXi blades, because we can not configure SNMP (or we).

  Which means that migrate us from HP servers for UCS blades, we lose the ability to monitor the State of the CPU and VM.

  How people monitor their virtual machines in an environment of UCS?

  Thank you.

  We monitor our UCS ESXi 5 with SNMP hosts and use Solarwinds NPM.  It works well.  These are the commands that we send through our VMA (free VMware) server to a new host.

  vicfg-snmp - root server - username - password it

  vicfg-snmp - root server - username - password you @162.

  vicfg-snmp - root server - username - password e

  There's probably a way to do it on the console of the host, but I don't know what it could be.

• Virtual machines running Win 7 OS

  I'm trying to get information on how to configure a virtual machine for Windows 7. I use virtual machines demonstrate software that writes my business. I have a virtual pc that is different for each demo that I show up to now, I've been showing the software in XP virtual machines but want to migrate and start showing the software in a version of Windows 7.

  I use Windows 7 Ultimate which is what I thought was necessary to create a virtual machine from Windows 7, but it isn't clear how get the operating system in the virtual machine. Should I buy another license of Windows 7 to make it work? I'll be able to create multiple virtual pc if I buy another copy? Virtual PC uses the 64-bit version?

  Any information would be greatly appreciated.

  Thanks - BP

  Unfortunately the Virtual Machines have their own separate license from the license of the host system. There are also a separate license for each simultaneous installation.

  In order to run a 64-bit VM host must be running in 64-bit as well, even if a 64-bit host can run 32-bit VM

  Each virtual machine is at least 2 files, a configuration file and then 1 VHD file for each hard disk, you configure (you can have more than one) in the virtual machine. You can have any number of virtual images, but the memory that you allocate is claimed when you run the machine will be how many can run at a time that is limited to the amount of physical memory in the computer, allowing for some to be available for the host o/s.

  Once you have the license of Windows 7 either convert the disk ISO (I use ISORecorder) or download the ISO image equivalent of Digital River. When you create the VM configuration use the control panel to include an optical drive and load the ISO in the drive. When you start the virtual machine, it will be BIOS start the virtual machine, exactly as if it were a physical computer and load the ISO the same as would a Windows 7 disc. It also works if you convert your demo software into an ISO file and install more quickly without having to use the optical drive on the computer.

• Put a host in maintenance - it will automatically move virtual machines?

  Dear all,

  We have a cluster with 4 guests and we would now like to upgrade each 5.50 to 6.0 ESXi ESXi host. I understand that we need to put the host in maintenance mode. He will automatically move virtual machines to other hosts? I read DRS is necessary. I see that our guests are permitted for Vmotion and HA. We have standard Vsphere license.

  This means in our case, I would need to move manually first of all VMs before the host can go into maintenance mode? In the case where the Vsphere will make work, the virtual machines automatically distributing to 3 other hosts according to the resources available?

  Thank you

  Edy

  This means in our case, I would need to move manually first of all VMs before the host can go into maintenance mode?

  Yes, since the Standard edition doesn't include DRS, you must manually move virtual machines to other hosts.

  In the case where the Vsphere will make work, the virtual machines automatically distributing to 3 other hosts according to the resources available?

  Yes, this would be the case with the DRS in place.
