• 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

• 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.

• 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)

• 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!

• 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

• 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?

• 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

• Virtual MACHINE running on two hosts after hung vmotion

  Hello

  I started a VMotion of virtual machine by host A to host B. The request got hung at 65% for several hours. I restarted the VCenter service, registered to vsphere. The process was running is longer, but now the virtual machine appears on the Host A and host B.

  The Cluster-'Virtual Machine' tab displays the virtual machine and cycles between two hosts seconds couple?

  Anyone seen this before? How can I fix it? Thanks in advance!

  First of all, it's impossible.  A virtual machine cannot be in 2 places at once.  It's just in the transition.

  Secondly, vCenter manages the process but it doesn't actually do the vMotion, ESX hosts are.

  What is happening is life of the virtual machine on the host only until the end of the evolution towards the other host (somewhere around 97%) when the transfer is confirmed with the new host.

  Best thing to do is to restart the services of management on both hosts and see if that frees the vMotion.

• Guest operating system freezes in a virtual machine running Workstation 6.5

  Hi, I am currently evaluating VMWare Workstation 6.5.1 (build 126130) on Vista Business 64 - bit and have migrated a physical installation of Windows XP Pro SP3 to a virtual machine.

  The virtual machine performs well except occasional crash which can only be remedied by the suspension and resumption of the virtual machine.

  I have searched the forums for related issues, but have not yet found a solution.

  Currently, it seems that the disconnection occurs when I have access to the network in the virtual machine, but it is hard to confirm.

  I turned on logging (attached a log file that precedes a gel), but the content does not tell me much. Are there other tools/options to diagnose this problem?

  Concerning

  Peter

  I solved my instance of the problem.

  Recently, I upgraded my host to a dual Intel processor hardware heart system Vista 64. After the upgrade, I changed the settings of the processor to use 2 virtual processors within the virtual machine.  I have run several virtual machines from XP (32 bit), Windows Server 2003 (32-bit) and Windows 2008 (64-bit).  On all of the virtual machine, I changed the setting to use 2 virtual processors.   I lived this problem only on the XP VM.  After looking on XP VM VMware debugging logs, always caused freezing of the errors be connected that the VM could not ask an interruption.  As this now seems a problem of interruption (rather than deliver a network - although the operation of the network were the trigger), I immediately thought of the CPU setting I changed.  I changed the number of virtual processors to one and the problem disappeared!  As I discovered other positions within this community, VMware will benefit from two cores, but does so at the level host hardware and not in the VM then.  BTW... My Windows 2003 and Windows 2008 VM retains the value to 2 virtual processors that they perform very well.

  I hope this helps some other members who have similar problems.

• Two virtual machines running at the same time

  Fussion 1.0, I remember being able to use two virtual machines at the same time, and each me each own IP without worrying if I used the bridged network configuration or address NAT. With the Version 2.0.1 (128865), only one will get an IP address and the other, the two XP SP3, visit account disabled NETWORK card. Any recommendations?

  Yes, it's tru, but I updated the vmx file to have another MAC. NIC I get this error when I try to boot the secondary machine (which otherwise boots fine solo).

  As I mentioned in the linked post, there are several unique identifiers that MAC address. Fusion has a UUID, and Windows has a SID. All must be unique (my guess is that it's the SID).

  The network bridge on/dev/vmnet0 of the device does not work.

  Which will result in network bridge does not work. The only suggestion I have right now is to try to restart the host, but demand around other people seem to be seeing this as well.

• Cannot add to the inventory if virtual machine running on the other guests - iSCSI and VMFS5

  5.5 ESXi hosts free standalone version

  iSCSI mounts with multiple paths - relatively new unit with more modern hardware

  CHAP not used

  I'm running a few hosts in order to climb the same iSCSI data stores. The iSCSI LUN is visible and editable by all hosts. If Host1 is to map the iSCSI LUN (VMFS5) and a VM is powered, Host2 can add that VM to the inventory. It's possible with NFS iSCSI for a reason any. This is for a specific reason? Only when I turned off the virtual computer can I add it to both hosts. Other that just lock files are placed in the directory, I missed something related to the lock?

  From now on, adding new esxi hosts does not allow me to add existing virtual machine, less than the voltage first. Once again, NFS does, iSCSI, this isn't. Any ideas?

  It is not specific to ISCSI but rather to the use of VMFS. NFS has no awareness VM VMFS is and why it is not possible to do that with iSCSI / VMFS. There is a lock on the disk for each virtual machine of (race), and that's why the second host is not able to add this host to its inventory. With vSphere HA, this lock is released when a failover should occur.
