How do I dynamically change the the number of vCPU and amount of a virtual computer memory?

Hi all

My first question is how do I dynamically change the number of vCPU and amount of a computer virtual memory when the virtual machine is running? If so, this may be achieved by writing a few scrpits to inform the hypervisor?

My second question is, I can start a virtual machine in KVM with the number of vCPUs and amount of memory configured in the startup script. I don't know if this is supported in vmware ESXi?

I couldn't find the answer in the ESXi 5.0 user guide.

Your suggestion will be highly appreciated.

You can change the ram and the CPU, but it must be enabled.

by default, only it isn't.

  • Dynamically change the number of sub-panels

    Hello

    I have a computer where usually 4 testplaces of production are connected to.

    I want to have a main VI indicating the status of the 4 different testplaces, that I can do with 4 separate sub-panels - no problem.

    The issue is that I would be flexible in testplaces how I show in a program (as this hole thing is pretty cool, and I expect that some changes will come). Is it possible to dynamically change the number of sub-panels displayed (other that make it twenty of them and turning off then those you don't need)?

    My first idea was to place the school in a table, but unfurtunately is not possible.

  • Change the number of VCPUs and memory

    How to change the number of VCPUs and the amount of memory to a computer the PowerCLI virtual?

    Steve is of course correct, you can use the Set-VM cmdlet to do this. But I suspect that entry PowerCLI reference online is a little more readable.

    An example

    Get-VM MyVM | Set-VM -MemoryMB 4096 -NumCpu 2
    

    See the xtrvirt VMware hot-add memory/CPU support for what is supported on what guest operating system.

  • How do I dynamically change the query VO

    Hello

    IAM trying to change the VO query dynamically. My forced, it is that I have 6 columns in a page header 3 columns (single default) for objective sort and another 3 columns (the default one) for querying data.

    Al, are in a single view so I created a VO.

    Sort of research
    AN A

    C C

    When I give all sort values and hit the query of VO submit button should change dynamically.
    I searched old post in this regard.

    My query is something like that

    SELECT * from cust_table where a = NVL (: 1, a)
    UNION
    SELECT * from cust_table where a <>NVL (: 1, a)
    order by one

    IAM not trying the Sub part dynamicaly in my AM method

  • How to change the number of unit and Master/watch on PC8164

    Hello!
    I have a stack with only two switches that have this configuration:

    Physically pass over: is asleep, and have the unit # 2
    Physically go under: is the master, and have the unit n ° 1

    Now, I want to change manually or in some way:
    1. I want to change unit number, so switch that is greater than 1 unit
    and put below to have the unit # 2

    2 change the master unit of switch below, above

    I can do these?
    Kind regards!

    CLI command "to initiate failover" translates into a warm restart of the master battery and triggers the unit to take over as master.

    stack of console (config) #.

    Console (config-stack) # initiate failover

    Use the command "becomes the" renumber units in the stack.  Example:

    console (config-battery) switch # 4 renumbered 3 (this command will be renumbered 4 unit to be unit 3)

    It won't let you set up a unit number already used, so you will have to shuffle unit 1 to 3 to "liberate" the unit number so that you can do unit 2 unit 1 temporary unit.  Then you can do the temporary unit 3 unit 2.

    I hope this helps.   B

  • How can I dynamically change the Format of Date of Application?

    Hello world...

    In my application (v 3.2) I let the user set the date format of app dynamically by a "preference" value, they can change on the road.
    I then take the format they take and affect their value (ie: ME-DD-YYYY) and pad "Hh: mi" for it and use it as the PICK_DATE_FORMAT_MASK that works very well for most of the selectors of dates.

    The problem I have is that some date picker, I use the application does not require the hh: mi, they need just the part of ME-DD-YYYY. I could use the NLS_DATE_FORMAT for this? I may be able to use the selectors of dates with the "format of date of application use? It doesn't seem to work for me.

    In other words, I need essentially 2 date formats for my selectors of application dates; 1 for just the dates and 1 for dates, including time. And these 2 formats are selected by the user by setting a preference of app dynamically at run time.

    Not sure if I feel here... any idea?

    Thank you!
    François

    You must use the element of the application in the installation of your application, so when you select in your control, you would use the date format of application level. You can change the level application through code or control element.

  • Change the number of competitors and pending workflow

    Hi all

    Is there a minimum amount of workflows that vCO will allow to run? I tried adding com.vmware.vco.workflow - engine.executors - count = 1 in the vmo.properties according to the http://pubs.vmware.com/vsphere-50/index.jsp?topic=%2Fcom.vmware.vsphere.vco_administer.doc_42%2FGUID-09C4D9D3-8C38-48FC-B1DF-5E3694B5E328.htmlfile, but was still able to run two concurrent workflows.  I would like to be able to run a workflow with the rest in queue!

    After the change is made, I restarted the service of vCO before the test.

    Thank you

    Mark

    The change you have made in the configuration files is the right place to change the behavior of simultaneously executed of the workflow. I can accept with Joerg, that it is a rather strange modification, but yes, you came to the best of the workflow (using locking for example or something similar).

    It should be noted here that, in the moment a work flow to the State of waiting, the following will start. The County is linked to workflows how are actually being run at the same time.
    (This is why many people releases that default of 300 simultaneous streams is in reality much more because most of the workflow enters the waiting state very often (waiting for other systems run the application)).
    Hope this is useful.
  • How do you dynamically change the enabled state of a control?

    I build a VI whose purpose is to generate a digital signal, post it on a chart and eventually save the data in a file. I have a trajectory control and a checkbox included in my front panel. When the box is checked , I want the State of the path control to be activated. If the check box is disabled , I want the State of the control path for disabled & clothing. Is there a way to get there or even just make it look like this?

    PS: I want also the checkbox for controlling whether or not the VI saves the data in a file, but I think I can understand the part.

    Right-click on the control, and then choose create the property node.

  • How to change the number of processors / cores

    I have virtual machines that I have to move periodically between 3 computers main host that I use:

    1 Intel Core 2 Quad CPU with Windows 7 Home Premium 64 - bit - 1 processor with 4 cores

    2 Intel Core i7-2630QM CPU with Windows 7 Home Premium 64 bit - 1 processor with 4 cores

    3 Intel Core 2 Duo T7700 CPU VT with Windows XP 64 bits - 1 processor with 2 hearts

    Hosts running VMWare workstation 7.

    Most of my virtual machines running XP 32 bit and have been initially created for my 3 platform.

    When I move my machines between computers I see that the parameters of the Virtual Machine for my change of processor in (for me)
    in unpredictable ways. Sometimes it shows 1 processor and gives me a choice of up to 4 cores.
    in other cases (always on a 4 base platform) 1 single processor with 1 core, in other cases, with 1 core 2 processors.

    In most cases, my freedom of choice is limited, because the selection of the number of cores is grayed out.

    When I try to make changes by editing the vmx file, I find them ineffective (no change).

    The other problem I think is that my VMs run VERY SLOWLY on my i7 with 8 GB platform!
    I have no idea if this is related to the improper setting of the number of processores / cores (I'm not able to define
    1-4-hearts and spin with settingsd 1.1 instead).

    Could someone please help me understand how:

    1. check / change the number of processors / threads on an existing virtual machine.

    2. how to set properly for an i7 processor

    Thanks in advance,

    Andrew

    1. providers that create virtual machines are in a race - they assume that customers use this version which proposes to use the virtual processors more ;-)
    For some workloads inside a virtual machine - say Oracle or other database and applications servers such that it is sometimes really good idea to use more than one virtual processor

    2. virtual machines to scale differently with more CPU than the real computers.
    Virtual machines are for host applications.
    This means that the host schedules the time CPU to each virtual machine.
    If you follow this thought that you will see that a virtual machine that uses one virtual processor has a greater chance to run then a VM with 2 virtual processors.
    A VM with 4 cores running on a host with 4 cores will spend a lot of wait time - it may work only when the host reports the application of Workstation 4 hearts are available.

    A virtual machine with only 1 vCPU will probably be able to run all the time without any waiting time.
    This is why usually with a single CPU VMs feel better to the needs of the user.

    This translates into the best practical advice: assign a CPU unless you really notice you need more.

    3. probably, you try to change the values, while the virtual machine is suspended?

    4.
    numvcpus = '8 '.
    cpuid.coresPerSocket = "4".

    We hear two processors with 4 cores of each

    numvcpus = "4".
    cpuid.coresPerSocket = "4".

    means a processors with 4 cores

    numvcpus = '2 '.
    cpuid.coresPerSocket = '1 '.

    We hear two processors with a carrot

    No effect? n ' mind that not all clients can use 2 or more processors
    For example, XP is limited in this respect.
    Some guests may also not change the number of CPUS after what they have been installed
