The virtual machine cannot reserve memory...

• Limitation of the Virtual Machine's CPU/memory resources.

  Hello

  My question on the tab "resources" with VMachine settings (I hope I picked the right branch here)

  In this tab I put a booking/Limit for CPU/memory for current VMachine.

  I have a cluster about 6 ESX servers with resource by default and a VMachine inside pool. VMachine have 1 CPU. Each ESX have 2 plugs with 4 core per socket. Each base equal to 2, 83GHz. Def.

  In this case, which by default configuration for an average CPU for this VMachine limitaion - 132582 MHz? Because in practice ESX server can give only 1 CPU for this VMachine and this CPU will have 2, 83GHz only...

  Also, I put 100% of CPU - 132582 MHz booking here... But in true VMachine will never receive this resource...

  Same question about limitation of memory...

  When this limitation will work? For what porpose such booking/limitaion here?

  Re: But, if I'm going to make a mistake and this CPU for VM value reserve, which is more physical limitation - it reduces resources processor for other VMs on a value that is more than the physical limitation of the virtual computer?

  No, the reservation only guarantees that if a virtual machine wants to take a large part of the resource at a given time VMware should give him.  If there is ever going to be a situation where the virtual machine is in fact to consider that much so it never gets allocated to this virtual machine and the amount of the resource remains available for other virtual machines to use.  Similarly, if the virtual machine just does not use the amount of the booking to a point in time, he let this resource can be used by other virtual machines.

  If a virtual computer uses only 1 GHz on a core 3 GHz system, at a given time but thereservation is 2.5 GHz, 1.5 GHz between its use and booking that is not used at this time is available for other VMS to use.  That is only if there is a period of contention between VM and VM CPU wishing to use mean 2.8 GHz it would be guaranteed to get 2.5 GHz independently of the parameters of the actions on the VM from other virtual machines.

  It is essentially the same thing with memory except that the memory usage is not as CPU flunctuate and VMware must also use more complex methods to reallocate the memory, but the leaders of the way in which it is shared using actions, reservations and limit is the same.

• Settings of CPU and memory of reserve on the virtual machine running...

  Hello.

  I have two virtual machines in production with CPU and memory settings of reservation applied as shown below. I want to adjust these settings of reservation to "zero" for the CPU and memory on both virtual machines.

  I can make these adjustments while VMS are running, or do I need to power their first?

  Any advice would be appreciated.

  Thank you!

  

  

  Welcome to the community,

  Booking of resources being completely transparent for the customer, i.e. a host function, there is no need to turn off the virtual machines. Basically all settings in are available to be changed in the editable GUI generally without interruption of service comments.

• Could not power on VM: no space is available on the device: cannot power on the virtual machine.

  VMware esx ei, 3.5.0 123629

  Physical memory: 64 GB

  Hard drive: 1.63 TB

  7 virtual machines. 5 of them are configured with 4 GB memory and 2 of them with 2 GB of memory. I am able to power on 3 virtual machines with 4 GB of memory.

  When I try to turn on 4th VM with 2 GB of memory, I get this error message "could not power on VM: no space is available on the device: cannot power on VM.»

  I would like to know if this is the limitation of the ESX Server? How should I size the memory for VMS if I want to run every 7 virtual machines to the

  Moreover, given that I have 64 GB of physical memory. Is there documentation that provides a report of the maximum allowed memory configurable

  compared to the virtual memory?

  Thank you

  Ganesh,

  Memory reservations are defined based on VM by VM.

  You can allocate more memory to the virtual machines you have in your host (it's not really a good idea to go crazy with the overcommitment of memory, but some level of excessive pressure is used in general).  Memory applied to your VM resources are shares, bookings and VMkernel Swap limits.

  Just to illustrate:

  You allocate 8 GB memory to a virtual computer.  If you take all the parameters by default, ESX will allot a 8 GB VMkernel Swap file in the base directory of your VM (it will have the extension ".vswp") this VMkernel Swap file is a safety net.  Your virtual machine, at this stage, can consume up to 8 GB of memory If physics is available from the host.  If the memory of your host is overcommitted, some of the available memory 8 GB could be allocated on 8 GB VMkernel Swap file.

  If you set a reserve of memory - 2 GB - this means that the vmkernel will still award the first 2 GB of memory used by the virtual machine to the physical memory.  This is not means that the 2 GB of memory reserved is carved off the coast and completely dedicated to the virtual machine.  This means that the vmkernel offers up to 2 GB of RAM to the VM when and if she needs to use it.  It is a guarantee that the memory will be available upon request.  Because of this guarantee of the VMkernel, VMkernel swap file only has to make sure that the 6 GB memory is satisfied (4 GB total less the 2 GB reserved), so the VMkernel Swap file is only 6 GB in size.

  Actions are a mechanism for prioritization and limits are a cap on physical memory ever allocated to the VM.

  You can set up any number of memory for the virtual machines that you want - frankly, overcommitment of memory for ESX is a very good thing, but you must be vigilant about watching your systems if approve you.  If you have 64 GB of RAM, and you only configure your virtual machines to use total 32G, then you lose 32 GB of RAM.  If you allocate, say, 96 GB of RAM (total) to your virtual machines, then you look at a 50% overcommitment.  What to watch in overcommitting memory is application performance (and more importantly - perception of the user of this performance) and also the memory ballooning and VMkernel Swapping activity.  Those who can both will be in graphics performance in VirtualCenter.  I would recommend reading the Guide to management resources for more details.

  Hope that provides an overview.

  Thank you

• Cannot start the virtual machine in a HA cluster

  I installed a HA cluster with 2 hosts configured in it.

  I disabled the admission on the cluster control.

  Each host is a Dell Dimension 9150 with 2.8 GHz CPU and 2 GB of memory.

  I created a virtual machine on a host with 1 vCPU and 512 MB memory.

  However when I try to start the virtual machine, I see the task of 'Power on a virtual machine' fail with the status "the host has sufficient memory resources to satisfy the reserve."

  Why this is happening and how do after that?

  You have the minimum RAM required by ESX ESX 4.0.

  Add more RAM to play also some virtual machines.

• The virtual machine on the logical switch NSX cannot communicate

  Hi all:

  My switch logic has been created and two virtual machines have been added, the virtual computer network are also connected to distributed port group, but the virtual machine of two Ping unreasonable. Two virtual machines can solve their MAC, the firewall is closed at both ends. Who can tell me why.

  Thank you very much

  Two things:

  1 try to run a traceflow between the two involved VMS network cards.  This should show you where the ventilation that is happening.  It might be a rule DFW or VTEP cannot speak for some reason any.

  2. its possible that the netcpa service is hooked on the host.  This is the process that communicates with the controllers.  For the involved hosts SSH and run the following command:

  restart the /etc/init.d/netcpad

• virtual machine cannot start, because the snapshot of the virtual machine has been deleted by mistake.

  virtual machine cannot start, because the snapshot of the virtual machine has been deleted by mistake.

  When I start this virtual machine, it prompts: unable to find the 0001.vmdk, this disc is my shot, has been deleted by mistake.

  How to restore this virtual machine.

  You need help with a revival of the 000001.vmdk deleted or do you want to repair the virtual machine so that it works without the snapshot?

  The last option, follow these steps:
  remove the virtual machine from the inventory and edit the vmx file so that it uses the basedisk. Then add the virtual machine to inventory.

• Cannot specify a directory for the Virtual Machine

  I'm new to ESXi naked with me.  I added some records and then to browse the data store and I added the folders in there to specify the different VM..., I have a XP Win7 folder folder, etc.  When I go to create a new Virtual Machine gives me only the choice to select a data store to store the HARD drive and not the folder structure I created in the data store.  Now I can delete the virtual machine to inventory, return to 'Browse the data store' and move the files, and then add the VMX file in the inventory, but it just seems like a pain.  Am I missing something?  Really can not be complicated to arrange your virtual machines, it can?

  Yes, you cannot specify a folder when you create a virtual computer to a data store.  I guess that he has not considered to organize things at this level and honestly.  Organization is really in the 'models and virtual computers '.

  Yes - you can
  but that will make your VM very slow

  set
  prefvmx.minVmMemPct = "50".

  or less - allowing you to approve the RAM

• Cannot use 'lab1' host because the host CPU is not compatible with the judgment of the virtual machine suspend state.

  I see that this error was mailed here, but can't seem to find a position with a resolution.

  We use Lab Manager 4.0.4 and just upgraded the hosts in our laboratory.  Before updating to ESXi 4.1 ESX 4.0 u1, we cancelled all VMs in all configurations.  There is none who were suspended, they were all turned off.  We have improved vcenter 4.0 to 4.1 as well.  We moved from a dell poweredge 1950 with two quad core intel L5410 to a r610 with two quad core intel processor E5506.

  When I try to turn on some of the lab configurations (our VM models all work fine), I get this error:

  • Cannot use 'lab1' host because the host CPU is not compatible with the judgment of the virtual machine suspend state.

  I threw the State for the lab configuration (even if it was turned off and cancelled) and still get this message.  I guess the processor architecture of these chips is quite similar, and both are Intel.

  If I go into this directory of Manager of laboratory inside the data store for one of these virtual machines that does not light and add to the inventory, he turned and starts fine on my server esxi 4.1.  So how do Lab Manager to get account it's well deploy and start it?

  Hey billk.

  Although not supported completely, you can solve it by going to the SQL of Lab Manager database.  Make sure that you back up your database before you do anything like that.

  Open the table "fsdir" and corresponds to the dir_id with the id Lab Manager VM.  Once you find the relevant line, change suspend_proctype_id to null (Zero-Ctrl).  You can do this while Lab Manager is still running.

  The results can be unstable (i.e. Windows can crash if it was a drastic change of CPU), but at least you look at a hard reset.  The bat reset certainly not being able to return to the previous state.

  Also note that while Lab Manager does not include CVS, if you activated, your virtual machines still work in CVS mode.  If you have a mixture of heterogenious of hosts in a cluster for Lab Manager, you can see this question pop up a lot.  There is absolutely nothing wrong with take back the virtual machine because of the VCA, but Lab Manager thinks otherwise and prevents it.

• Can not power on virtual machines "cannot access the file because it is locked.

  Virtual machines have been working well - then the storage system is down.  After the storage system returns upwards that I can't turn on a number of virtual machines.  Get this error when I try to turn it on:

  Cannot power on vmname on esxhostname.xxxxx.com. Unable to access file < unspecified file name > because it is locked
  error

  1. To check the locks on the Service Console on non ESXi servers, run the command:

     lsof | grep

     COMMAND PID USER FD TYPE SIZE NŒUD NOM_PERIPHERIQUE
     71fd60b6-3631 root 4r REG 0.9 10737418240 23533

     Note: If there is no Console of Service process the locking file, you should receive no printed output. If you receive results, however, file a support request to identify the process and to determine the causes.  If it is a third-party process, however, contact the appropriate provider to determine the cause before you kill the process ID, because it can happen again in the future.

     Stop the process and the lock ID using the kill command. In the example above, the process ID is 3631:

     kill the 3631

     After the termination of the process, you can try to turn on the virtual machine or access the file resource.

  2. To check if the virtual machine is always a world ID assigned, run these commands on all ESX/ESXi hosts:

     CD/tmp
     VM-support - x

     Available to debug worlds:
     WID =

     On the ESX/ESXi host where the virtual machine still works, kill the VM, which releases the lock on the file. To kill the virtual machine, run the command:

     VM-support - X

     Where the is the ID of the world of the virtual machine with the locked file.

     Note: this command takes 5-10 minutes to complete. Answer No to "can I include a screenshot of the virtual machine", and answer Yes to all subsequent questions.

     After the termination of the process, you can turn on the virtual machine or access the file resource.

  Deleting the file .lck (NFS only)

  The virtual machine files can be locked via NFS storage. You can identify this as reported by .lck files. # (where # is the ID of the world that holds the lock file) at the end of the file name. It is a NFS file lock and appears only when you use the ls command as it is the hidden file.
  Beware: they can be removed safely only if the virtual machine is not running.

  Note: VMFS volumes have no .lck files. The locking mechanism for VMFS volumes is managed within VMFS metadata on the volume.

  You must kill the process that is locked, if it is not the case, you probably need to restart the VMware host.
  I tell you from experience most likely end up rebooting it.

• Cannot convert a virtual machine while it is powere on or suspended. Shut down and power off the virtual machine before the conversion.

• Cannot move the virtual machine to another host

  Here's the situation... I am running 3 ESX 4.0 host in a cluster and I upgrade the memory on these hosts.  I put one day and now I want to use vmotion to move a virtual machine to host more memory, so I can then turn off host 2 to add more memory.

  When I try to migrate the computer to another virtual host he said "the virtual machine must be powered down for that purpose."

  I did it before with success when I first created this group with the HA and DRS settings are enabled.

  Now, I can't do this and I don't know what setting or what changed to cause it to not allow me to manually migrate a virtual computer on one host to another.

  If I wanted to put an ESX host in "Maintenance Mode" thinking that it will automatically move all VM for 2 other hosts in the cluster is not it either... I get a message saying that ' a host into maintenance mode does not any virtual machine functions... blah... blah... and continues to complete the entry into maintenance mode, all virtual machines must be closed or moved to another host. "  Manual intervention may be required.

  Again, I think that if a host is down these VMs would be move... that of the whole point of a cluster but doesn't seem to put in maintenance mode to allow them to go unless I turn off the virtual machine

  Any ideas?

  Go is one of the requirements of vMotion. The message after you had corrected the condition, I'm sure would be erased after awhile.
