• 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,

  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.

• backup of the virtual machine fails HotAdd mode if the virtual machine is running?

• 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

  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

• Two virtual machines running on a same PC network

  Hi all:

  I'm running both SUSE Linux Virtual Machines (VM) with VMPlayer on a PC with Windows server 2008. The two virtual machines are configured to the bridge at the same host physical ethernet port (bridge mode). Started the first virtual machine can access the network without problem, but the second VM started not. The order from VM has been changed in order to check if it was a configuration problem on one of the virtual machine, but according to the virtual machine that is launched in the first place seems if appropriate switch VMnet0 and block access to the second VM. Defined for each virtual computer LANs are different: 10.2.1.0/24 for a VM and 10.4.1.0/24 for the other.

  Any help will be really appreciated

  Case resolved, I realize that he had a message waiting in the toolbar of VMware by saying * adapter Ethernet0 do not have network connectivity. MAC 00 address: 0C: 29:58:61:19 adapter Ethernet0 is located between reserved address or is being used by another virtual card on your system. *. I just checked on google and found an identical case on the VMware communities with the solution: http://communities.vmware.com/thread/269465?start=0&tstart=0. To make the story short my VMs have been duplicated and used the same MAC address. So just stop a virtual machine and generate a new MAC for him in settings-> settings-> Advance-> ECS

• 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!

• 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:

  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).

• cannot not power off the virtual machine, but don't think the host it is running!

  I have two clusters VI3. An older cluster to 3.02 hosts and a new cluster with ESXi hosts. Level of current patch on ESXi hosts. New guests and old presenters sees the same storage, but I have additional storage which can see only the new virtual machine.

  Most of the migration to the new cluster went very well. A few questions. But a VM just GIVES me fits.

  After the failure of attempts to migrate the virtual machine to the new storage, I thought I just migrate the virtual machine to the new host and leave it on the old storage, for now, until we could find something later. VCenter events logs show that the migration has expired. However, the virtual machine appears in the new cluster and is no longer in the old cluster. Also, he turned on itself for some reason any. Turn off in Vcenter gives the error "the operation failed because another task is underway." Having the VM that I could put it off in before Vcenter, and no no unsure of how to use the RCLI for this, I have connected to the host directly mode "not supported" and has run vm-support - x to get the list of running virtual machines and their ID's so that I could kill him. However, the host does not include this virtual machine in the list of virtual machines. So I think a virtual computer that runs Virtual Center, but he thinks the host it runs on is unclear if I can't kill the process.

  Help?

• 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!

• What is the best way to restore virtual machines after a refresh of the server

  Hi all

  First time poster here. A group of people at my work have their own VMWare environment which they install later. It has 3 virtual machines running on it, and they want to set up a fourth. Unfortunately the new machine, they want to put in place is going to be almost 1 TB in size, and they initially setup the VMFS datastore to 1 MB, which means that a machine can be as large as 256GB.

  Research, it seems that there is absolutely no way to work around this problem, except to redo the data store. Is this correct? If this is the case, I was looking at a way to save the three current machines and to reload them after it is updated. A way that I thought was to go browse the data store and copy all the files on my local machine to the virtual machine (.nvram, hard, .vmx etx... all the files), wipeout and redo the ESXi host with the correct setting of data store, build the machines VMS in vSphere, and then replace the files with those copied. This works perfectly? I don't see a lot of information out there about it and I want to make sure that I have not to spoil the VMs. This environment consists of 1 ESXi host with all the local storage (2 TB).

  Also, if anyone knows a better way to do this, please feel free to give your comments. I would really appreciate it.

  Thank you

  Yes, unfortunately there no way to change the block size of the datastore to vmfs without reformatting.

  Yes, it will work. You have just to copy all files in this VMFS datastore to a place safe and download once the block size has increased. Once the download is complete, navigate to the virtual machine, the virtual machine folder right click and save the VMX.

  You can find the steps to change the size of the block VMFS in this KB. VMware KB: block the size of a VMFS data store limitations
