Restarting the management agents on ESXi 4.1 / risk to restart the guest virtual machines?
Unfortunately, we must restart management on our HP ML350 G6 agents almost once a week (unable to connect with VSphere client more, customers are works well).
We know this Article -: restart on an ESX or ESXi Server management agents
and this article useful: http://www.vm-help.com/esx/esx3i/ESXi_restart_agents.php
How can we avoid the ESXi 4.1 command /sbin/services.sh restart will restart our execution of virtual machines (guests) as well?
(Our first test shows: it restarts the guests, but it is sure, or just happy coincidence?)
According to the second article linked:
... This will restart the agents installed in /etc/init.d/ and with a default installation that includes: pass, ntpd, sfcbd, sfcbd-watchdog, slpd and wsmand. He is aalso restarting the agent VMware HA (AAM) if that has been activated on the host...
Each of the agents of this is responsible for our virtual computer operation invited?
Do we ensure "auto start/stop" to each virtual machine too (as written in "Attention" on the first linked article)?
I think it was on ESX 3.5 U3 corected. In any case, this happened only if you autostart enabled for VMS - the ability of ESX Server to boot VMs when it starts itself. If you do not need, leave it disabled.
Each of the agents of this is responsible for our virtual computer operation invited?
Not at all. Virtual machines running in a very low level of the VMkernel. Even if you lose the COS (which is your main problem here - you should check it...) the VMs will still work.

Restructuring of the pagefile to the guest virtual machines
Is there a directive to rigtsize the pagefile for guest virtual machines (Windows)?
With the hosted versions of VMware (Workstation and Server), I used to create a swap file whose size was RAM * 2 and place it on a different disk from the system disk / boot: can it be good for VMware ESXi as weel?
Is there a better solution?

that will depend entirely on the Organization of the underlying hardware and the OS and app loading on these drives. Having said that, generally, is not a big deal provided that machines have anyway enough RAM.

Use of memory in the guest virtual machines
Hello
I don't have any background on VMware technology, but we are using a facility of dynamic cloud based on vCloud Director to the company where I work.
The group that operates the server publishes the offer with a 'pay per use model"of service.
This is true for the CPU resources, as we pay only what we use in the month. But in my opinion, it does not for the use of the RAM.
We have Linux VMs that allocate a 4 GB of RAM 'physical' and our monthly bills show that the RAM usage is at 100% for all the month. But when you look at the tools of memory for the virtual machine, you can see that most of the time 50% or even less is used by the guest operating system process.
This means from a user perspective the RAM price per month should be half of what we are responsible now. Ask operators on the 'question', we always get the answer that the use of the RAM is not dynamic and we need to pay for the use of 100% from the point of view of the server host.
Could someone share some light on this subject? Is there really no way to make use of the dynamic RAM as the CPU usage?
Thank you
Michael
Evening,
As a service provider, I'll let you in on the secret:
It depends on
vCloud takes care of three models of default allocation. Your provide may use other
-Pay for what you use. -pay as you use
-Allowance - you get resources, but can burst more
-Booking - you get allocated resources and is
Chargeback depends on model (in out of the box chargeback... your provider might have something custom)
Pay as you use - charged on the basis of the resources used
Allowance - remuneration based on allocation and additional for burst
Allocate pay based on booking-
There in the last two models really no way to load except full allowance (i.e. 100% cpu and RAM)
Statement, I think you have something along the lines of the compensation you are using you mixed with a price system vendor.
From my experience the resource more used in ESXi clusters in the RAM. That's really what I buy in clusters of resource... I always need more RAM. I need no more CPU. In addition, distribution of the CPU to vcloud is made via Ghz is not CPU. RAM is allocated by GB. So those set up and I think you suppliers is betting that they will always have to RAM so they charge based on usage not allocation. While CPU, they have tons while they charge by usage.
Really, it's just my thoughts... What can charge you on:
-Ghz processor
-GB of RAM
-GB of storage
How can recharge you:
-Used
-Allocated
So bottom line... they can charge by opportunity they choose not too...
It will be useful,

Manual removal placeholder VMs when the protected virtual machine is removed
We run SRM 5.5. We had some VMs protected, we need more, so they have been removed from the drive (I can't). When I found out about it, I went in SRM and removed the protection for these deleted virtual machines. Most of the VMS placeholder have been correctly removed by this procedure, however, I see still 2 VMs of space reserved for virtual computers that no longer exist. No idea why only these 2 (about 6) were not cleaned.
My question: can I remove manually just these VMs placeholder? They are not in any group of protection, or the stimulus plan. And the protected virtual machines which correspond to these placeholders no longer exist. It's as if they are zombie placeholders. :-)
There is no problem with me removing the VMs placeholder manually, y at - it?
Hello
Yes, its safe to delete the place holder vm. Make sure the source VM is not protected and no replication is configured. Restart the SRM service.
Thank you

How to set up the generic dashboard for the specified virtual machines
I have two question about "generic dashboard":
1. I use the tag to classify certain virtual machines by role QA, DEV or PRD. If I select "Kind of resources", and then select all VM under a label, window "metrics selector" will be watch only "vCenter generated Operation Manager", it does not show metric VM. How can I see it?
2. If I select the 'Resources' mode, then I'll be able to see the VM metrics on the window "metrics selector", but I must key in each VM name "Label to the area", it takes a lot of time if I have a lot of VM, is there no matter what symbol I can use to match this field with name column "resource"?
Mode 'Resources like' or 'Resource', both ok for me, I want to just install a widget to display using the specified CPU VM real fast.
Any information is appreciated!
You will see that vC generated Ops metric because you are looking at the tag, which is a resourcekind. This switch of resources is "not" a filter label, these are the actual resources. If you want to see all the virtual machines, select the resourcekind 'virtual machine '.
Generic dashboard is rarely used to show - all - kinds of resources, it is generally used for static selection for specific purposes. If you want to display all types of a resource type and apply a tag filter, you can select a different widget to display this information.
There is no symbols that can act as wildcards, as you suggest. When you are 'kind of resources' mode, you need not fill out a label for the box.

Hello
I was wondering if it is possible to transfer everything to a virtual hard disk that is smaller on a virtual hard disk that is larger in VMWare Workstation, using the same virtual machine? In the affirmative, please could someone advise me on how to do it. Also utility management and disk transfer can be used in virtual machines to do this?
Thank you very much
Tim Auluck
I'm not sure what exactly you are asking. Can you please clarify!
Basically you can resize a virtual drive or add a second virtual disk to a virtual machine and transfer/copy files. You can also resize the virtual disk using VMware Converter for example.

People,
This issue has been resolved,
Details of the problem:
RAM 512 MB only, use JVM parameters
"" Arguments of memory in JAVA: -Xms512m-Xmx512m ".
If WL struck to use more memory for the start and the stop MedRecSvr2, 3 (managed server)
Please read the following steps to correct,
1. open Oracle VM Virtual box
2. go to settings and select the system option (make sure that all OS turns off).
3. go in card mother in this window select Base memory previously is changed to 1920 MB (1.875 GB) 512 MB.
4. click on Ok.
Then the allocated RAM will be more, for Weblogic doesn't get knocked because of insufficient RAM memory.
Respect,
Bouchra Arun

is it a good idea to run the JAVA virtual machine inside the hypervisor?
If I want to write a global user inside the hypervisor platform and you want to reuse some java lib, it's a good idea to install and run the JAVA virtual machine as part of global programs of the user inside the hypervisor? Thank you.
Maybe you listen to the wrong people?
The ESXi hypervisor is pretty well stripped of the linux console you are talking about, there is a thin busybox linux like environment, but you are strongly advised not to run anything in there.
Performer of applications within this console may have all kinds of side effects such as severely affect the performance of your computer virtual guests.
Why the hell would you want to run the JAVA virtual machine inside the hypervisor? What is the reason why you want to do this? If it's because you get a better return, then you're wrong, the console becomes just a little bit of resources available on your host computer.
If this is to go directly to the features that the hypervisor provides then the VMA we're talking is the answer.
So getting back to your question initial for EACH use case that I can think it's a very bad idea.

Installation BAR inside the Android virtual machine files.
Hello everyone!

I have an Android app that can install any other Android Apps (think like that as a personal App Store for Android). Now, I want to convert to BlackBerry. What I have done.
Now what I want to know, is how my application (BAR the file running inside the Android virtual machine) to install other files BAR? Y at - it any option (API?) that can escape from VM Android for QNX for I might be able to install a BAR?

Cannot create an instance of the java virtual machine
Hi when I try to launch my sql developer get this error
Cannot create an instance of the java virtual machine located in the path C:\Program Files\Java\jdk1.6.0_38\jre\bin\client\jvm.dll, but I do not have the file in the location
I'm trying to do
BI CHAOS: SQL Developer: cannot create an instance of the Virtual Machine Java
Cannot create an instance of the Virtual Machine Java
but am not able to locate file product.conf in my machine
OK, we lost time because you said never explicitly release of SQL Developer in use, and then, when I deduced this wrong, you went right with it, rather than correct me. Remember the line from Blade Runner when Harrison Ford hits Rutger Hauer in the head with a pipe? Than hurt!
Anyway, since the last post (because of the osgi references in the file ide.conf) I see that you are using a version 4.0.x of SQL Developer. You must update the file product.conf with the smallest Xmx value in order to create an instance of the JVM. If you have not yet found the product.conf file on your system, this might help: http://www.thatjeffsmith.com/archive/2013/12/oracle-sql-developer-4-windows-and-the-jdk/
Otherwise, ask someone in your organization COMPUTER help - keep in mind that AppData is one of those hidden Windows directories, so you'll have to tell explore to make it visible by the organize > Folder Options > view > hidden files and folders parameters. In addition, you should use Java 7, not Java 6 - try to get that upgrade to the latest version of jdk1.7.0_xx (currently 60, I think). Since you never said if your JDK is 32-bit or 64-bit, I can not say to use an AddVMOption, Add32VMOption or Add64VMOption.
Best wishes

High using the Virtuakbox virtual machine CPU load
I have a MacBook Pro 2.5 GHz processor dual-core Intel Core i5 (Turbo Boost up to 3.1 GHz) with 3 MB L3 cache.
I use VMware Fusion Pro 7.0.1 (2235595) to install and use Windows 8 to run the Simulator on my MacBook internetworking solution.
These simulators come with Oracle VM VirtualBox and they used to run in the Windows virtual machine on my MacBook Pro with no problems.
So far, no problem!
However, after upgrading to OS X Yosmite 10.10.1 simulators no longer work due to the high utilization of the processor by VBoxHeadless.exe
I deleted the virtual machine, I uninstalled VMware Fusion and reinstalled, then reinstalled the Windows operating system, makes all the possible update and finally installed solutions simulators without success to have any Simulator market, they used. The reason is always high utilization of the processor by VBoxHeadless.exe as seen in the following images:
I then moved to bootcamp and all do it again. Now simulators all run as before but on windows on the bootcamp partition. Now I can even run a lot of devices in simulators like in the following photos with no problems:
Please, do you know how I can fix this problem? I prefer to use VMware fusion because it gives me more room for what I want to achieve compared to the bootcamp.
There is a difference between the hosts with regard to the information provided by windows on the ability of the virtualization of the MacBook.
I thank very you much in advance!
Kind regards

Your problem unfortunately was not something that other people recognized as a problem they had seen or they simply didn't have the time to answer.
The majority of the Fusion users will not also have installed VirtualBox.
However, I am glad to hear that you found a solution (in a restaurant) and please let us know.

Two POS devices back up the same virtual machines
Hello
So my goal is to have weekly backups to a unit of POS, and monthly backups go to another device of POS, on a separate data store. I'm stuck on VDP v5.1.1 because since I can not upgrade my vCenters yet. What I'm trying to do, is to protect my backups to a store of data or corruption VDP OS - which have already occurred in the past.
My question is, I'll be able to simply deploy a 2nd POS device and tell it to save the same virtual machines that are already underway by the 1st POS device? I wonder what that complications would be, i.e. If the 2nd POS only runs a monthly backup, it will be smart enough get all changes since the last monthly backup or he'll come CBT files since the last daily backup of the 1st POS device?
Thank you!
You can make backups in this way with 2 POS devices and CBT is treated properly. Monthly backup will take more time because of the higher number of changes. Look at the time of the departure of the backups, they will take parallel steps.

Problem fixing existing vmdk to the new virtual machine
Hello
Just upgraded to Fusion 6 and things seem ok (except for the dreaded license bug, but it's ok now).
I'm having a problem attaching a form of virtual disk existing a VM - operation - existing. Basically, all the vmdk files are grayed out and non-eligible, regardless of the option to share / copy / to support the disc.
I checked that I have full R/W access to the fie (and it works fine if I fire up the other virtual machine).
Any idea?
Well I ended up adding another player new to the virtual machine, I wanted to and the drafting of the description of disk (Disk DescriptorFile #)
in the manually - vmdk file works great...

Not configured VM prevents the recovery of the configured virtual machines?
I try to test a recovery plan. There is a problem with one of the virtual machines on the data store. It has a disc attached to a volume that is not replicated.
When I run the plan, it logs the error below for all of the active steps after "Suspend Non-critical VMs on recovery Site".
Error - virtual "name VM" machines that
are not protected by this protection group use warehouses "Volume name"
that are in this protection group.I understand that I can't protect this particular virtual machine. The question is if it will prevent the other virtual machines being restored or is something else going on?
If you have a data store in a protection group then * everything * VMs on this data store must be configured for protection, otherwise it will fail.
That is, if it is not protected SRM is not aware, cannot stop it and which will not be able to remove the data store, etc.
