• 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

• hosts mixed esx 3.5 and older new vsphere with vcenter 4.1 esx hosts. Need advice please.

  Hello, I have an existing the vcenter server install managing two esx 3.5 hosts. The vcenter is version 2.5.0.x. I want to manage my new hosts of vsphere 4.1 esxi through the vcenter. I would check that if I improve my vcenter 2.5.0 for the last version vcenter Server required for the 4.1 that I will be able to manage my old esx 3.5 hosts? Will be an upgrade inplace vcenter 2.5.0.x support now the license server in place or I will have to manually install this after? Thanks for any info. Doug Dorbuck

  You can mange ESX 3.x host with vCenter 4.x - you can't manage ESX 4.x, vCenter 2.x hosts

  I think that in a place of upgrade will keep the license server - otherwise you will need to reinstall the server-licensing

• 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.

• VSA: "host not valid management gateway."

  I get this:

  Invalid host management gateway. Should be the same as that of VC

  When you try to configure our VSA. The server vCenter DO NOT HAVE ACCESS to the INTERNET and does not have a gateway on it because of that configuration. We don't want these machines to have access to the internet.

  So, that being said, what is a work-around, or a way to solve this problem, without connection to the internet.

  We don't use DHCP, all is static and I disabled IPv6, respecting the troubleshooting steps: http://kb.vmware.com/selfservice/microsites/search.do?language=en_US & cmd = displayKC & externalId = 2004832

  For some reason, my Google looking for this error brough to the top of this article...

  If it comes to VSA 1.0, then the vCenter server and ESXi hosts who will compose the VSA cluster must be on the same subnet.

  If it comes to 5.1 VSA, then the vCenter server and ESXi hosts that make up the VSA cluster may be on different subnets.

  Is what version? I guess it is 1.0.

  In this case, gateway to the Victoria Cross must be on the same door as your ESXi hosts, even if he is a "dummy".

• Add production ESX hosts to a cluster

  Hi all

  I did some research in the admin guides and community forums, and I'm sure that I know what to do, but I would really appreciate a test of consistency here because the manipulation I do is in a production environment:

  I have a campus that contains two ESX areas that are managed by using vSphere and connected to a San. vMotion of works very well, the performance is very good (although the resources of the two boxes are fairly complete upward). However, I recently realized that I'd neglected to set up a cluster HA and DRS.  I want to remedy.

  I created the cluster with these specs:

  • the two HA and DRS, enabled
  • to the left, she also fully automated.
  • the power management of left
  • monitoring and host admission control enabled
  • leave the default settings for the behavior of the virtual machine
  • monitoring VM disabled
  • EVC enabled
  • the storage value of the swap with the virtual machine file

  I think that the next steps would be to add each ESX host consecutively and merged its resources with the cluster. However, here are a few questions:

  • How do you assess the risk factor to do this in a production environment (1 = perfectly safe, is a proven Scenario; 5 = you are out of your bloody mind? Do not)
  • Should I be triple-checking the SAN snapshots and planning of downtime for servers, or is it possible live and without any major qualms?
  • Am I right in assuming that it will increase my performance as well as provide better robustness of the campus, or should I expect a decrease in performance?

  Thank you very much in advance for your advice!

  Hey red,

  Addressing your particular situation, I would say yes to two questions.  Admission control HA is here to help you.  Ensure there are enough resources on the host computer to run the current and any expected load it will be after an HA event.  50% is close to default (but it is really based on the size of the slot) in an environment with two guests when guest cluster failures tolerates is set to 1 in a two and 25% host environment when the percentage of unused reserved as production capacity cluster resources in failover is left to its default value.

  If you have several virtual machines running that allows you to book 50% of your cluster resources (which it sounds like you have), then you have the option of "first category" your virtual machines and their giving priorities to restart event HA.  For their level, you'll want to active DRS (can be set to manual Automation), resource pools and you will need to configure your virtual machine under your HA settings options.  You'll want to pay attention to the priority of restarting VM here.

  I suggest you take a look at blog Duncan Epping http://www.yellow-bricks.com/ and Frank Denneman http://frankdenneman.nl/blog. They are all two fairly well the definitive answer to the HA and DRS questions and advice.

  See you soon,.

  Note: Epping and Denneman explained that the amount reserved by default resources when you use the host cluster failures tolerates is promising to reserve enough resources to power on virtual machines.  This reserve of resource does not on average current, account, or future default load.  If you want to manipulate this feature, modify the memory and CPU reserves, which are the numbers used to calculate the size of the slot.

• 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

  Hi Nick,

  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.

  It is either a problem with the network configuration or there is a firewall blocking some ports.

• 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.

• 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.

• 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.
