• vCenter on an ESX host that it manages...

  vCenter is on its own server outside the farm of ESX servers, or is it a good idea to put it on one of the virtual machines on an ESX host, that he himself is the management?

  For example, if we have set up a HA cluster, which includes the vCenter vm... and the ESX host fails at the hardware level, another host will turn upward from vCenter virtual machine?

  Virtualize vCenter is a common configuration and supported. No problems with the DRS and HA.

  Welcome to the community - I would try to remove the host to vCenter and see if you can see the local storage.

• Connect the ESX host and data store on another ESX host

  Hello

  assuming for this scenario:

  Host ESX 1: esx1

  Host ESX 2: esx2

  It is possible to mount esx2 datastore in esx1? (For example: via NFS). Of course, it is possible use a NAS/SAN intermediary, but I wonder if it is possible to achieve a direct mount.

  Thank you

  Eddie

  Well, to allow another host to share the local data store, the host must be able to act as an NFS server. The problem is, there is no service in one of the ESX version which able to serve that. So, as said what a.p., no, is not possible.

• How a VMGuest can see a number of physical ESX host processor

  Hello

  Not sure if this is expected behavior or not, but I have some application that runs from a linux machine to vmguest in my cluster Vsphere 4.0 U1 that is able to see the number of sockets processor busy on the ESX host that it is currently at. I never saw that happen up to now on another system in our environment. On Linux operating plan, when you run the "cpuinfo", the show only reviews the number of virtual processors assigned to it. I don't know how this program is able to see all the way down beyond the virtualization layer to the actual physical hardware layer on the esx host.

  My first thought was that this was triggered after the installation of the VM Tools on the guest operating system, but even after turning off the service tools you can still see the real taken account on the host computer.

  Can someone explain to me how this is possible?

  Thanks for any info you can provide

  Regardless of the tool that allows you to watch the CPU I have a strong suspicion about what is happening here.
  The exact CPU type in/proc/cpuinfo is listed: "AMD Opteron Processor 6164 HE.
  I guess that the tool you are using has some knowledge (using an internal list of program or by retrieving this information somewhere on the internet) that this CPU has really 12 hearts and he only relies on it and reported that the machine has 12 cores, instead of looking at what is really reported by the operating system.
  So, he just does not have the right to work and is not aware of virtualization.
  In any case, it is not really able to look directly into the hypervisor.

• How to find VCenter which manages the ESX host

  Hi all

  Is it possible to query ESX host using API to determine if it is autonomous or managed host and if it's a managed - what VCenter (name, IP address) actually runs it. I know it's easy to VCenter query to find all the hosts its handles, but I need to go the other way.

  Thank you

  Yes, you can query for the http://vijava.sourceforge.net/vSphereAPIDoc/ver5/ReferenceGuide/vim.host.Summary.html managementServerIp if defined, then it is managed by a server vCenter Server, this is the only information on the vCenter Server and assuming you have DNS, you can get the FULL of the IP domain name

• Can you run various NUMA parameters on ESX host?

  Hi all

  We are running ESX 3.0 and have experienced a problem with some our fair virtual servers randomly close I googled the error message displayed in the case where newspapers that lead me to the article below in the VMware KB.

  http://KB.VMware.com/selfservice/microsites/search.do?language=en_US & cmd = displayKC & externalId = 10213

  This article is about the exact message we receive, so I am confident that its troubleshooting procedures should work as we run the NUMA architecture in our environment, but I have a question before the change of management being curious to know a bit more information regarding hit her on the effects of his settings of NUMA in our environment.

  That's why we have taken two ESX hosts in our environment, my question was the following can I make NUMA changes on an ESX host and then migrate (if they aren't already) servers that have had the shutdown problem random overall to the ESX host that has the correct settings of NUMA as detailed in the article above?

  If any of you out there have done this before? If so is there any bad shot on the effects that I should know about? Any comments or advice you can give me on this would be greatly appreciated! Roll on the migration to VSphere 4.0!

  Thank you

  Nick

  Hi Nick,

  That's why we have taken two ESX hosts in our environment, my question was the following can I make NUMA changes on an ESX host and then migrate (if they aren't already) servers that have had the shutdown problem random overall to the ESX host that has the correct settings of NUMA as detailed in the article above?

  No Yes No problem with that. The VM themselves are not aware that they are running on NUMA hardware, so will not notice. The bug is because the vmkernel does not release memory properly when a virtual machine gets on demand on one NUMA node other than that which has been started the. Configuration Numa.MonMigEnable effectively disables this behavior at the host level, but this does not disable the advantage of NUMA so you may notice a performance decrease.

  Not sure of your patch levels, but apparently it was 'fixed' with this patch: http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=2066306

  Kind regards.

• Two vCenters and mobile from one to another ESX host

  I have an existing vSphere environment where all virtual machines on the local drive. This environment is managed by a physical vCenter Server.

  I've built a WHOLE new environment with three hosts and each has 4 Sockets, 6 hearts with 128 GB of each host. I also created a new vCenter Server and it is a virtual machine. All are connected to the iSCSI SAN.

  I know that the ESX hosts can be managed by a vCenter server at a time. Now, I want to add old esx hosts that have virtual machines on a local drive to the new environment that is connected to a shared storage. When I try to add a host on the new vcenter server, I get a message saying that the host is already managed by the old server vcenter and if I add it to the news that it disconnects. Which is the best way to do it, or should I disconnect hosts from the old server vcenter first?

  Also how I will move the virtual machines on the local disk to the San. I have company over 4.1.

  Thank you!

  I unplug and remove the host from the old environment and then add the host in the new.  This will allow your guests to continue to operate.  Once you have hosts in the new environment, you can use sVMotion (right click to migrate, move the datastore) to move your guests to a shared storage.

• You can restart nfs storage WITHOUT having to reboot ESX host?

  Hi community

  I wanted to know what your experience has been reset to the nfs storage devices WITHOUT having to restart the ESX servers. I can stop the virtual machines that use the storage, but would like to avoid off ESX hosts as they require a visit to the data center for put in operation and I can do all the rest of the House.

  My options are either then restart the ESX host (that I can do it remotely of course) or the ESX Server restores in the nfs storage when it is up?

  This is the first time such a restart will be required so I use

  this as a learning experience and the VMs on those ESX hosts are not

  criticism.  (although don't tell users which.) )

  Thanks in advance

  Yes, of course you can.

  ESXes automatically reverts to the storage.

• Add more disk space for the ESX host

  Hi all

  I need to throw more disk space to my ESX hosts.  I know how to bind records in Navisphere and present to the ESX host.  Once in the VI client, I "think" I need to go to the host and do a rescan of the HBA or something like that?  I'm a little unsure of the market of part VI to add more disk space.  Could someone just point me in the right direction?  Please note that I am looking to add more disks to existing hosts in existing clusters.  It adds no storage to a new host... rather an existing one.

  Thank you

  Jonathan

  You are on the right track.  Re-scan storage card, under the configuration tab select storage adapters, select the adapter and click on the link of the new analysis.  Then go to the storage section and there should be a link in the top right of the screen that says storage Add.  Click on that and it will guide you in adding/setting in form/naming of the new disk.

• Virtualize vCenter and patching ESX hosts

  I have a host two cluster HA with VSphere Essentials Plus, so no vMotion. (I know... good budget restrictions). It's a whole new infrastructure, so I only have a VM... my vCenter server running on host 1 (config) supported in a small size like mine environment

  I use VUM patch my ESX host that requires that the guests of had no VM and be in maintenance mode.

  The problem: How can I migrate my virtual vCenter server to my other host in order to set the host mode of maintenance and patch 1 (requires a vCenter runs).

  My thought: two guests can see the LUNS for the vCenter server. I think I can go into host 1, power off the virtual machine and then remove from the inventory. Then, I'm going to host 2, browse the store of data LUN and ADD it to its inventory. Is this correct? If so, what file in the data store can I connect to the host (vmx, vmdk, etc.)

  Thank you.

  Yes, it will work, but you will need to attach the base to a host at a time line.  You would add to inventory the .vmx

  Or use the command line

• ESX host think client has connected CD but doesn't have a customer?

  I had a VM I want to storage vmotion, but I get unable to act thus think the ESX host that a client has connected CD/DVD. No one has any console open to it.

  Vmotion message is:

  Virtual machine is configured to use a device that prevents operation: device "CD / DVD Drive 1" is a device connected with remote support [/ quote] "."

  When I go to change the settings for this virtual machine, it says under the CD/DVD Drive 1 that it is connected to another customer. Not called Vmware support, they have got no idea, tried to restart pass and vpxa, but neither helped either.

  Someone has any idea how to solve this problem, without power down?

  If the CD is connected to the client device connection persists until it is manually disconnected or connected person CD closed session (vSphere Client). Even if the VM Console is closed connection persists.

• Disconnected ESX host cannot add to the CR

  It started with me being unable to power on a virtual machine that I created because of "Insufficient resources to meet the level of failover configured for HA" which is great because that's how to configure HA.  I tried to reconfigure the AP to the host by double-clicking on the host and select this option.  Once I did that it failed about 30% with "an error has occurred while setting up the HA Agent on the host" and the networking page disappeared from the configuration tab similar to what a lot of people reported during the upgrade, I think an earlier version.  This is not the case, I did not update anything.  Then I restarted service service mgmt-vmware restart and the ESX host disconnected from the VC altogether.  I can't use the VI client to connect to the host in question, but I am connected via the service console. All VM and the host not to requests ping and everything works. I've disabled HA and DRS and tried to add new ESX host that has not worked.

  Any help is appreciated.  Thank you.

  I found this article that has the same symptoms as you.

  http://KB.VMware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalID=1004451

  Check if your esx.conf file is corrupted. Follow the directions in the KB article to restore or recreate.
