Execute 4vCPUs virtual machines on an 8 core physical ESX host?

I have to run 4 * 4 vCPUs on my ESX Server. I only ESX Server with 2 processors and each has 4 cores = 8 cores in total.

Is that enough or what is best practical value if I have to run 4vCPUs?

If you more search 100% CPU. It's ok if half of your vCPU do no actual work at any given instant, in fact quite common. If they do a real job, you will have a problem of great claim and you will see big time of loan that predict you. There will be no difference in the movement of 2 cpu invited if this is the case, because you always need the number of cores to support threads you have (assuming the same bitrate).

In case the vCPU is not all busy or they are all busy together then you should be fine but it costs a treatment in order to keep the guest SMP in a valid state of ESX - threads must even if progress, they are not "occupied". If ESX is working hard to achieve this, then you will see CSTP esxtop elevation %. This means basically that ESX is having to stop/reschedule the son in the virtual machine just to keep active when the real work he would do otherwise. So at this point, you can better with smaller virtual machines. Order our planning on the blog document VROOM.

  • Script to list all the warehouses of data in a cluster, the virtual machines on the data store and the host of the virtual machine is on

    We have warehouses of data which are seen by more than one cluster. I need a script that will display:

    all stores of data seen by a cluster

    the virtual machines on the data store

    the host of the virtual machine is on

    the cluster the host is in

    The output I want is

    name of the store of data, the VM name, host name, the name of the Cluster

    any help would be appreciated

    Pretty sure this will do what you need:

    $report = @()
    Foreach($cluster in Get-Cluster){
        $datastores = $cluster | Get-VMHost | Get-Datastore
        foreach($datastore in $datastores){
        $vms = $datastore | Get-VM
        If ($vms.count -ge 1){
            foreach($VM in $vms){

  • Run a virtual machine with a graphical interface on a host without GUI

    Hallo

    I want to install a simple Windows 7 for some tasks bit where I need Windows on my server Ubuntu 14.04. This server has no GUI (no X) and should have any.

    Already, I've installed the virtual Windows machine on my workstation to 12, so I would just copy the vmdk on my linux server and run it, maybe put something in the vmx file.

    But I do not know is that it's all means possible.

    Is it?

    Is there any player or any application for ubuntu VMware when there is no X system (on ubuntu), where I can run virtual machines with GUI inside?

    Maybe another virtualization tool, vmware not?

    I think that this exact question already somewhere, but I haven't found much question where comments lacking a GUI, but not the host.

    I need a guest-gui on a host without gui (where I have only the terminal).

    So maybe it's not possible at all, so please tell me a 'no', so I won't expect more

    Thank you to

    Frank

    EDIT: oh, this seems to be another question unanswered it is too difficult or too stupid?

    Hi Frank,.

    Now that would be stupid, having a text Installer, and then not allow the virtual machine to run. I think it should work, but you must pass the nogui option.

    Vmrun help:

    beginning

    (Supported only on teams

    Workstation.)

    Starts a virtual machine (.vmx file) or team (file .vmtm).

    The default graphical user interface option starts the machine in an interactive way,

    What is necessary to display a user interface of VMware.

    Nogui option suppresses the user interface,

    including start-up, to allow dialog box not interactive

    writing scripts.

    [gui | nogui]

    refer to the manual of vmrun: VIX API Documentation

    Edit: hmm... Now, I see that you have already tried the nogui option. You might be able to install the package libxinerama, but he could hang out in a lot of dependencies.

    FWIW, vSphere is pretty much what you describe a system not GUI to run GUI invited, so it shouldn't be a problem at all.

    Unfortunately, I don't have a host linux without X installed handy here, so can't test here without the implementation of a server without head myself.

    You can also try to run the client via the command vmware:

  • Cannot start the virtual machine guest after receiving "License expired message" host ESXi 5.5

    I can't start computer virtual invited after receiving "License expired message" 5.5 ESXi host. I am able to copy the vm folder prompted with all its files using WinSCP I had already installed on a desktop computer in the network.

    However, it takes an extremely long time to download the VM [2.5 mb/s], which is of course a different question.

    It seems that I was still on the trial with my vsphere client license, until it expired. I am able to view the virtual machine within the workstation 10, but I can't turn it on. It says "Please install a license to power on this computer" there is no way to install a license anywhere.

    My question is... .will I be able to access this virtual machine if I download on an external hard drive, then add it to 10 VMWorkstation that I possess a current valid license?

    Even if the evaluation license has expired, you should be able to connect to the ESXi host using the vSphere Client and follow the steps mentioned in the article that I posted before you enter the free license key.

  • VCenter shows a network for a virtual machine that is not associated with any host

    I have a win2k3 VM who at one point had a network assigned to him called "MONITORING".  This network is configured is no longer in the ESXi (5.5) environment.  The virtual machine is connected to a network called "PRD-SURVEILLANCE" which is correct.  It's not really cause a problem, but I can't find a way to get rid of the object of MONITORING network.

    In VCenter MONITORING networks has a VM of 1 meter, the number of hosts of 0.  I also see it in the VM - dialog box, change the settings, but there is no option to remove it.  Profile Image to the virtual machine is version 10 so I can't use the old Client of VI to try to remove it.  I have checked each host and do not see this listed network object.

    I tried to restart the VM, it migration between hosts, changing its network of SURVEILLANCE of PRD to another network and vice versa and close - remove NIC and add a new card network.  MONITORING legacy network still appears in the config.

    For the virtual machine's .vmx file shows that the correct network: ethernet0.networkName = 'RDP-ANALYSIS '.

    Any suggestions on how I can remove the artifact of MONITORING network?

    The virtual machine has a preview that was created at the time where the MONITORING network was still affected?

  • Unable to the virtual machine to a remote desktop another PC host then.

    I recently installed VMWare workstation and created a virtual machine that I can't access via RDP from any machine other then the host.

    I am able to access internet from the virtual computer hosted together with the machine to do hosting.

    IP OF THE VIRTUAL MACHINE

    vnet1

    192.168.126.1

    eth0

    192.168.2.3

    I understand that the vm and the host can communicate because they are both on the reseau.245.x, but how do I get the VM to get an IP address from my dhcp server so that I can rdp to VM?

    I would be grateful for any assistance with this issue.

    Lost in the sauce.

    B

    At this point how to configure a network adapter on the virtual computer to get an IP address for an existing dhcp server?

    To gain a better understanding of the VMware Virtual Infrastructure of network I strongly suggest you read 14 chapters (setting up a virtual network) & 15 (advanced virtual networking) in the Manual of the workstation user , still less the rest of the documentation. (Also available in the help file of VMware Workstation).

    Then change the virtual computer's network adapter to use connected by a bridge.

  • Best method to move virtual machines Linux of VC 2.5/ESX 3.5 to 4.0/ESX4 vCentre

    Guys,

    I have to move a number of them. The two groups are there. If it is not a question about the upgrade of the VC/ESX. I want to use the simplest method possible to move these VMs and here's my plan:

    1 copy the whole directory of VM from the data store on VC 2.5 to the data store on vCentre 4.

    2. Add the virtual machine to inventory in vCentre 4.

    3. upgrade VMware tools

    4. switch to hardware version 7.

    And that's all. Please let me know if this plan is feasible, or more importantly, no holes in the plan.

    Thank you

    Hello

    You have a few options:

    1. you can bring up the old data store for ESX 4.x and save the VM on vCenter 4.0.

    2. you can add that the host ESX to vCenter 4.0 3.5 move virtual machines in ESX 4.0 cluster.  You can use vMotion and Storage vMotion, according to your needs.

    3. you can use the stand-alone converter to make a hot cloning of Linux virtual machines in ESX 4.0.

    Best wishes / Saludos

  • Do we not have to change the settings for the virtual machine once moved from 2.5 ESX to vSphere 4.1?

    Hi guys,.

    I just wanted to check, once the virtual machines are migrated from ESX 2.5, 2.5 Vcenter to ESX 4.1, Vcenter 4.1 of the NFS datastore on the iSCSI data store.

    Do I have to make changes to the vm settings?

    To use the features to enhance available with ESX 4.1 what I need to change the virtual disk to logical Bus to LSI logic? What is recommended or is not serious?

    It will be very useful for me to know if there is any need for changes to be made other than on the virtual machine upgrade vmware tools.

    Thank you

    You try to run ESX 2.5 VM on ESX4.1, if that's the case then ESX 2.5 VM are not supported on ESX 4.1

  • I don't want my Virtual Machine to synchronize the clock of the host

    I'm using VMWare Workstation 7.00.203739

    My PC is Windows XP SP3

    My Virtual Machine is Windows XP SP3

    I don't want my virtual machine is synchronized with clock 'the real machine', then reading here and there I put these lines in Windows XP SP3.vmx

    tools.syncTime = "FALSE".

    Time.Synchronize.continue = "FALSE".

    Time.Synchronize.Restore = "FALSE".

    Time.Synchronize.Resume.Disk = "FALSE".

    Time.Synchronize.Shrink = "FALSE".

    Time.Synchronize.Tools.Startup = "FALSE".

    However, after 30 minutes I work inside the virtual machine, I see that comments clock synchoronizes with the host country.

    What have I forgotten?

    Thanks for your advice

    When this occurs after the virtual machine is in place, for a while, I guess that you have activated the service 'Windows Time' - it disabled via services.msc

  • Migrate virtual machines Citrix Xen Server for VMWare ESX 3.5

    Hi all. I have a requirement to retire a Xen server and migrate all the reviews virtual machines running on it on a newly developed VMWare infrastructure (wooo hooo).

    Only problem, it's actually have to migrate these servers because their construction is relatively complex - so my question is:

    Is it easy / what is the best method to convert our Xen Server VM (all Windows Server 2003) in some form of transferable file and import into the new VMWare infrastructure?

  • Accident of ESX 3.5 but virtual Center did not perform vMotion on virtual machines

    Hello

    We have 3 ESX servers on Virtual Center 2.5. One of the ESX Server suddenly restarted due to hardware failure. There were 5 virtual machines on this particular ESX host.

    When we check all the VMs who resided on the ESX host touched, he has just restarted and didn't vMotion for the rest ESX servers

    The question is why don't the vMotion VMs to the rest of the other servers. The rest of the ESX host have more than enough CPU and RAM to accommodate all 5VMs

    My understanding of vMotion would be when an ESX host is down, all the virtual machines will be migrated to other ESX hosts on the cluster.

    When an ESX host is down, the migration of all virtual machines to other ESX hosts in the cluster is not a VMotion functionality, but this is a feature of VMware HA. The vSphere availability Guide:

    "VMware HA offering high availability for virtual machines by pooling their and the hosts they reside on in a cluster." Cluster hosts are monitored and in case of failure, the virtual machines on a failed host are restarted on alternate hosts. »

    Therefore, enable HA of the cluster to achieve the desired result.

  • Host CPU is not compatible with the requirements of the virtual machine in the level 0 CPUI register x 1 'ecx '.

    I have a cluster of three ESX servers.  They are IBM 3650 and they are the exact same material bought at the same time.  They even the same exact versions of the firmware (bios, bmc, nic firmware, HBAs, raid, HDD firmware, rsa, etc.).  I started their reclassification of ESX 3.5u3 to ESX4 with all the latest patches.  Then I updated one moved some top vm and upgraded vmware tools and virtual materials without problem.  So, I went and upgraded the following ESX Server and has started moving the machines on that one and upgraded vmware tools and virtual hardware.  I tested the functionality of the ESX servers and they seem to work fine.  I vmotioned machine version 4 hardware virtual machine between the two developed level ESX host very well so I me with the upgrade process.  Then I had to vmotion, one of the virtual machines updated (version 7 of material) between the two ESX hosts newly improved and they won't vmotion.  It gives me the error CPU host is not compatible with the requirements of the judgment of the VM to CPUID level register 0 x 1 'ecx '.  The full error message is in the attachment.

    Apparently, the virtual machine hardware upgrade exposed a few additional things virtual machine that prevents vmotion to work.  I don't know what and I'm quite surprised because these machines are identical identical hardware and firmware.

    All of the suggestions.

  • Failed to create new virtual machine

    Hi all

    I have a 5.1 ESXi cluster and I try to install a new Windows Server 2012 R2 virtual machine.

    The process always fails this question:

    "A component of the virtual machine is not accessible on the host computer."

    I tried to:

    • Change datastore (VMFS 3 and 5)
    • Change Vfolder
    • Change the amount of RAM and the number of CPUS
    • I tried disk as Thin provisioned or felt configuration.
    • Check the health of these two hosts: seems OK

    Nothing changes

    Any suggestion?

    Thank you

    Create and manage templates are based on vCenter server only and that's why you see not view 'Virtual Machines and templates' inventory... .and the VM files.

    Instead, you will see all your virtual machines from home-> inventory directly under your host...

    If I install a virtual machine in a host instead of using the Vcenter server, I don't see these files,

    What it means? you have successfully created VM via vSphere client connected to the host?

    So my question is: when the virtual machine is installed, and I reconnect using Vcenter where did I see this virtual machine? I guess that I'm not in the folders 'models and virtual computers '.

    You will see that it is not executed in the title of the last folder in the folder list or in the folder named "Discovered virtual machine"... until you insert it to some... by vCenter
