VM ESXi 2 times with 2 vCPUs and 3 vCores

Hello

First offshore, I use ESXi 5.1 and the sage of material I use is 2 x Hexcore X 5650 2.67 GHz, 48 GB of RAM and RAID 1 SAS 15 k disks 600GO

I ran into a problem where I bought a server spec higher to go along with our other our dedicated hosting company, however, I went Dual cores to processors dual hexcore that now puts me over my limit of 8 cores on ESXi.

So my question is, that I can only use a maximum of 8 cores per virtual machine and I have 12 available physical cores, would be 2 virtual machines with 2vCPUs and 3 vCores use all 12 physical cores, or would it still restricted to using only 8 of these carrots?

Also, wouldn't be good (balanced load) the idea of using 2 VM with 2vCPUs and 4 vCores?

All advice and guidance welcome.

The limit of 8 cores is without limit to the ESXi, but for virtual machines. Your ESXi can use all cores of your physical. Your virtual machines can only use 8 vCPUs (up to the standard license. Enterprise and Enterprise plus can vCPUs 32/64)

So that already answers your question:

So my question is, that I can only use a maximum of 8 cores per virtual machine and I have 12 available physical cores, would be 2 virtual machines with 2vCPUs and 3 vCores use all 12 physical cores, or would it still restricted to using only 8 of these carrots?

Your ESXi host will use all 12 physical cores. By default, each vCPU contributes to a logical core, which is a physical core if you disabled hyperthreading.

Also, wouldn't be good (balanced load) the idea of using 2 VM with 2vCPUs and 4 vCores?

I would recommend not only to assign as many vCPUs to the virtual machines that you can, but start with little vCPU and increase in this number, as you can see on the guest workload is high that you need more vCPUs. less can be more in virtual environments, try not just to migrate your 1to1 physical servers to virtual.

For quick theoretical example: If you got 4 physical cores and 2 VMS with 4 vCPUs each, each physical heart will serve 2 vCPUs. In this example two virtual machines can run faster with only one or two vCPUs earch.

  • I can't get into my yahoo favorites. I spent time with AT & T and the conclusion, they have come to is that it can be a problem with Firefox and yahoo. Help please

    I use a laptop computer HP NOT mobile. Whenever I try to go into my favorites YAHOO that it asks me to sign in which I'm doing nothing does not. AT & T came to the conclusion that maybe it's that Firefox and Yahoo do not work together. I just downloaded the latest versions of Firefox and toolbar yahoo again without success. Is there something with Firefox that prevents me to enter my yahoo Favorites?

    You have the box checked for automatic private browsing mode? In this case, when you open the Options dialog box, the drop-down list usually said "conservation rules: don't remember history. In this mode, Firefox does not retain your Yahoo cookie between sessions, which would explain the problem.

    Note: If you uncheck this box and start in normal mode, you can still create private windows via the menu or with Ctrl + Shift + p.

    If the problem is not caused by a parameter of Firefox, it is possible that an add-on or software external is clear your cookies between sessions.

  • Relative time with the Parent and child Comps

    Hi, is it possible to see the time a child-comp has in her own scenario, and in his own timeline window see what time there in a certain-comps-chronology kinship?

    I tried several views, but could not display 2 different comps and / or move the time slider to a model he moves in the other computer too...

    Kind regards

    Frank

    Well, that said Rick is the first to check, but by default, this option is enabled, so I wonder... Your compositions are in fact really nested or y at - it something to do that we do not know? As well use the parameters of the model and adjust the com time beginning when necessary. Desp you can always use simple expressions for anotehr comp time and attach it to the effect numbers...

  • Problem with several swfloaders and file a swf

    Hello!

    Is it possible to load a SWF file at run time with a charger and then when the load is finished to set that is contained in a source for SWFLoaders two or more property? Because now if I don't have that content is presented on the last SWFLoader and others show just a blank space.

    Here is the code I use:

    _loader = new Loader();
            
    _loader.contentLoaderInfo.addEventListener(Event.COMPLETE,onLoadComplete);
    _loader.contentLoaderInfo.addEventListener(IOErrorEvent.IO_ERROR,onIOError,false,0,true);
            
    _loader.load(new URLRequest(a url where the swf file is located));

    private function onLoadComplete(event : Event) : void {
         swf1.source = event.currentTarget.content;
         swf2.source = event.currentTarget.content;
    }

    After the class can be useful in your case:

    How can I return to 4.0 3.6 I've never had a problem with 3.6 and now 4.0 crashes all the time tell me how to go back

    Downgrade to Firefox 3.6 first of all uninstall Firefox 4, but do not select the option 'remove my Firefox personal data '. If you select this option, it will delete your bookmarks, passwords and other user data.

    Then you can install the latest version of Firefox 3.6 available to http://www.mozilla.com/en-US/firefox/all-older.html - it will automatically use your favorite courses, passwords etc.

    I recommend, to avoid possible problems with decommissioning, accessing your profile folder and delete the following files if they exist - extensions.cache, extensions.rdf, extensions.ini, extensions.sqlite and localstore.rdf. Delete these files will force Firefox to rebuild the list of installed extensions, check their compatibility and cancel the toolbar customizations.

    When the iPhone is connected and Photos opens, select iPhone in sideba of the windowr of Photos. Then, uncheck the option 'Open for this iPhone Photos' below the toolbar.  Do this for all your iPhones. The hook should be unmarked for each device individually.

  • My iPhone6s pairs with ONE single device (phone link2cell). will pair with something else, and "bicycle wheel" changes all the time! Any suggestions?

    My iPhone6s pairs with ONE single device (phone link2cell). will pair with something else. At the opening of the Bluetooth window "bicycle wheel" next to "Other devices" is always running as if the search! Any suggestions?

    When you open the Bluetooth section in the settings, you can still see the spinning wheel, because it is in discovery mode and is actually looking for other devices in the range. Other devices must be in discovery/torque for the device mode to find them. However, I'm not sure you can be associated with multiple devices at the same time with the iPhone. You can have multiple devices matched on the phone, but you can always not more than one partner at the same time. It depends on what it is you are trying to pair.

  • Why can't acquire data from strain and resistance at the same time with a NI 9219 module?

    Hello

    I use a chassis with a NI9219 module 9172 cDAQ to try to acquire the strain and resistance at the same time, with the Labview SignalExpress software.  Is this possible?  When I try to display two values of signal at the same time, I get an error of assistant DAQ 50103 'the specified resource is reserved.  The operation could not be performed as indicated.  I used to be able to acquire the strain and tension at the same time, but now even that gives me error 50103.  I have hours trying to figure this out.  Any help would be greatly appreciated.

    Thank you

    I installed KB263380 KB2572073 and KB2518864 three times with success; However, I get the yellow shield saying that I need to update to Windows XP

    I ran the Mr Fixit for this problem, and briefly, the yellow shield disappeared, I thought that it worked.  But as soon as I clicked the solution worked and Mr. Fixit was gone, the yellow shield came back and said that I have to update these once again.

    Thanks for the article.  The icon stopped appearing after the third time I've updated from Windows.  Someone must have solved the problem to Microsoft.  I did nothing except reboot several times.  Finally, the Update icon went in itself.

    You need to replace the battery in time clock (RTC) real of your computer.  It can also be called the CMOS or BIOS battery.

    Many computers, this battery is an inexpensive CR2032 button available in almost every pharmacy corner.  There are, however, some computers (especially laptops) that require a different (and probably more expensive) battery.

    Whatever the expense, almost all of these batteries are easy to replace.

    To get help, post back with the brand and model of your computer.
