ESXi 5: sharing 4 cores with VMs - parameters of vCPU 3

Hey people,

First of all, I shamefully admit that I am relatively new on ESXi and while I could probably find the answer in the plethora of documentation, I spent hours and come up with nothing.

You are looking for a simple answer to a simple question:

What is the best way to share also the 4 cores of the processor (4 physical cores on the host node) with 3 virtual machines?

I know there are a lot of variables that can be introduced to the equation (type of software used, VM operating system, etc.), but I just want to give each virtual computer as the equal of a hand as possible.

Right now I have 2 virtual machines, each with 2 vCPUs and I really like my performance but I'm seriously slot using our resources.

I would like to add a third VM and divide the 4 hearts among the 3 VMs.

My stomach says to give 4 vCPUs each virtual computer and let ESXi balance the load.

Am I wrong?

-Scott

P.S. It's a 1230 E3 Xeon with hyperthreading disabled, so it comes with 4 logical cores, not 8.

(1) Please HT turn on again.  Modern HT on Ivy Bridge help to 99% of the performance of the application... especially with ESXi.

(2) If you come to give all computers virtual resources equal (say, 4 vCPUs) and don't change anything else, they will be treated equally.

  • ESXi host does not synchronize with NTP - causes HA config failures?

    Hello

    We are currently implementing some Cisco UCS systems. We using blades Cisco UCS B200 M1 (x 5670, 48 GB of RAM)

    Everything seems to work fine except these little things, which seems to be related.

    1 NTP synchronization is not happenning, or happening very slowly.

    2. a 10 cluster host, when it is configured for HA, has many guests who fail to be configured for HA (for example we had only 2 guests get properly configured for HA out of 10).

    Initially, I thought REP 1 and 2 were not related, but then I remember reading somewhere that the ESXi host must have simultaneously for HA to work.

    On question No. 1:

    10 guests have a difference of 5-6 minutes between them. Curiously, the first hosts that are connected to a HA cluster, if their duration is similar, they wil work.

    But others are more than 1 to 2 minutes off, they will fail. Our NTP is configured on 2 internal NTP servers, which syncs with the outside world - the 2

    NTP servers are:

    The default gateway of each ESXi

    The network Core switch

    We know that the NTP servers work correctly because our advertising is synchronized with them and we checked on our domain controller local time main external time source.

    Debug information

    Output of /etc/ntp.conf

    ~ # cat /etc/ntp.conf
    restrict default kod nomodify notrap nopeer
    restrict the 127.0.0.1
    Server 10.*
    Server 10.*
    driftfile /etc/ntp.drift

    Everything has been configured through the GUI, I show the output of ntp.conf for confirmation.

    We tried to restart the hosts (without success).

    Everyone knows what we can do to solve this?

    Thank you

  • Functions defined by the user with several parameters

    I set features three following user using "Define."

    UF1 takes a single patameter;

    UF2 takes two parameters;

    and UFX takes two parameters - with the second is 'X' in the definition.

    Œuvres F1.  F2 is the EVAL of F1 version and it works too.  User functions only seem to work fine.

    F3, a function of two user settings, produces a graph of NaN.

    F4 is the EVAL of F3 version.  Note that 'B 'is not replaced by 1'.  Also produces a NaN chart.

    F5 produces a graph of NaN.

    F6 is EVAL of F5.  The 'X' is not replaced (even with the ' B' above), and even if it looks like 'X * X', it also produces a graph of NaN.

    Is it possible to get defined by the user, with several parameters, features work by tracing the curve?

    Hi!, Fortin:

    If you download and install the ultimate Firmware with the version of the software: 2015 6 17 (8151), with the number of Version: 1.1.2 - 11, you can trace your examples of definition of the function, with curves and values, without NaN.

    Hi Hp community.

    I am tring to get a new model on my computer called nolimits coaster 2 software. I had the demo and it runs pretty slow. I don't know if it's a memory or a CPU thing but I would love to get this without having to buy a computer brand new if possible. Here are their requirements: Windows 7 or newer, 2.6 GHz Quad Core with 4 GB of RAM, compatible Direct x 9.0 c (Shader Model 3) with 1 GB of video RAM

    Thank you, Michael

    Hello

    The following link shows the specifications of your computer:

    As you can see, no way you can upgrade your machine for video 1 GB of RAM you given cannot go to 2.6 GHz CPU (maybe not image) and 4 GB of RAM. You buy the new machine to meet the requirements.

  • CORS with ADF

    Hello

    We strive to implement the CORS with domain CDN to be kept in the static content web server.

    We have added the Access-Control-Allow-Origin * in the file httpd.conf of OHS (11.1.1.7.0)

  • 301 redirect with get parameters

    Hello

    My client's old site with the url structure http://site.com/folder/folder?page=1234

    All of these pages should be redirected to the new page in the new Adobe BC site.

    But it seems impossible. Redirection does not work with get parameters and works without it.

    Is there a decision?

    This is because there is only a single page and player parameters things like ajax to load content so 301 redirects do not work.

    You must run the google web master tools and apply the tricks of setting filters.

  • Sharing a font with a third-party designer

    I work with a magazine (as an employee), and we have hired a third-party designer as an independent contractor to help with some aspects of the layout. We will give it a try for a question to see how things are going. Unfortunately, it does not have the police that we use for our titles, subtitles, etc. I wonder if there is any problem sharing my copy with him, at least for the trial period. My license agreement allows me to install the font on up to five computers, but I don't know if that would extend to an exit from the House, designer of third-party (I think that it is not). But I don't like spending $250 for all the different weights of the police if we end by not working not not with the designer in the long term.

    Any thoughts?

    Well, you're right to be cautious, to the extent where most licenses, including the time Adobe, do not allow that kind of sharing. He must have its own license for fonts.

    As a broad principle, it relies entirely on license specific end-user (EULA) in question, and these differ widely among foundries. But few of them allow such use without a licence separately the additional user.

  • ThinApping an Application with several parameters

    Still new to ThinApp please bare with me.

    I have captured a request and I now have an App.exe and an App.dat.  Then, I opened this request, altered some settings and captured these changes & named settings1.dat.  I have also settings2.dat, settings3.dat and so on.

    App.exe is about 50 KB
    App.dat is about 80 MB
    Settings1.dat, Settings2.dat and so on is 2 MB.

    How can I go on these chaining so Settings1.dat/Settings2.dat/etc calls and run App.exe and App.dat?

    I don't want to wind up with more than 80 MB file, which is the only way I could make it work.

    These settings are changed are all stored in HKCU, so this is a simple registry change.

    If you want to get started ThinApped application with different parameters, you need not separate .dat files. What you can do, is something like the following:

    1. Install your application, change its settings and capture it with ThinApp.
    2. You change the application settings, and export the appropriate registry key.
    3. Repeat step 2 all the time.
    4. Go to your project directory and create a subfolder in the folder where your application executable.
    5. Copy the .reg files exported in the subfolder created in step 4.
    6. Create a script or a batch file for each .reg file, and then save it to the folder created in step 4. The script file or batch must have the necessary code to merge the .reg in the registry file.  Also, you must run the main script executable file or batch file.
    7. Add the necessary lines in the package.ini file to create an entry point for each script or batch file.
    8. Build your application.

    Another approach, you can create a menu with an InputBox statement. In this way, you can choose load settings before running your application.

    1. Follow the steps 1 to 5 of the previous approach.
    2. Write a script to create a menu and merge the corresponding .reg file into the registry according to the user's selection.
    3. BUiD your application.

  • See the users that you have shared a Script with

    Is there a way to see the users who you have shared a script with?  I spent in and added the email addresses of a few people with different roles and wating to do a couple things:

    • Make sure that everyone who needs to access, I added
    • Who are the co-authors or commentators on the color code

    I don't see anywhere that I can view those which I gave access, to check or do one of those two things.

    Your help is appreciated.

    So that the script is not accepted by all the world appears as a Document not shared. If you click not shared Document your name would appear there with the owner role. As soon as the first person to accept the script, it looks like Shared Document (2 users) and clicking on it would reveal your name and the name of the worker. This number and the information contained in this area would be keep to increase as users increasingly accept the sharing of the script.

    but when I use a single parameter as:
     <af:goLink text="Run Report" styleClass="xes" destination="/printreportservlet?reporttype=pdf"  targetFrame="_blank"/>
    or
    <af:goLink text="Run Report" styleClass="xes" destination="/printreportservlet?filename=new_report.jasper"  targetFrame="_blank"/>
     
    It works successfully,
    so is there any problem to send several parameters while asking us to servlet.

    Best regards

    What happens if you put this URL in the address bar directly, it works? If it isn't, then it seems that the problem is with your servlet. If this does not work, try to escape the ampersand in the URL.

    Then extended this table management will be managed according to the tablespace or storage settings which
    has been specified when the table was created.

    Hello

    This means that we don't have to define NEXT, PCTINCREASE, MAXEXTENTS at the object level.
    Then, these settings are applicable to Dictionary managed tablespace or what?

    Yes that's right, understand you is correct

    Can we define NEXT, PCTINCREASE, MAXEXTENTS at the level of the object in the dictionary managed tablespace;

    Yes, you can, but go for DMT, is not very good, because you advantages compared to LMT, just think about it before going to the DMT, than I suggest.
