• Manager Update and patching ESX hosts

  We have 2.5u3 with ESX 3.5u2 VC.

  We want to use VMware Update Manager to patch the ESX host. I created a reference database containing patches ESX and attached to a host ESX to test. I have a scanner and it came with 28 patches that need to be installed, which is ESX update 1.

  Why would it need to install ESX 1 update when we already run ESX Update 2?

  No idea, or do I just exclude it?

  This is a bug of gui... it will not be applied.

• 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.

• 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

• Problemao com o vCenter e um ESX host

  Pessoal bom dia,.

  Estou com um problemao na empresa em than trabalho. EU estou com meu vCenter for one, porque o servidor Québec tem o banco dados dele (UM Windows 2012) nao esta respondendo rede of na. AI, fled try access host em o Banco o vCenter hospedado esta, e ele esta travado... I can not fazer nada nele... Quando tento access esse host travado o vSphere Client, appears using a mensagem abaixo:

  

  ELE nao esta com o ssh enable, nem nada... Finally, I can not acessa-lo of jeito nenhum. I think minha unica alternativa e desligar host manualmente o. Só Qué meu e as VMs that are nele piece is corrompam, e la tem VMs important para o ambiente, por isso venho aqui pedir um auxilio pra voces. Have any outra alternativa EU possa use? UO vou ter than correr esse risco e dar um desligar o accommodate manualmente?

  Desde ja Agradea§o an ajuda.

  Primeiramente, do only one virtual host machine SQL Server esta nesse parou answering machine or all you other VMs also answering sem are? SE elas estiverem acessiveis, seja pelo RDP/SSH, Bivvy logar em uma por e uma achieve... e desligamento cada uma delas product o no o reset host final.

  Very is nenhuma VM host desse estiver respondendo awesoe than a Solução simplesmente reiniciar o will host, e como as VMs ja sem answering machine are, o risco danificar as tao VMs nao sera alto.

  Minha ultima recomendacao e only as ja that o SSH no host nao esta enable, Bivvy logar diretamente pela console using an ILO/iDRAC/IMM e acessando o DCUI, don't make restart o host.

• Update and patching ESX 3.5.0

  What is the best way to update a standalone ESX Server 3.5. We normally do our updates through VC but this server is standalone and is not managed by VC. Download the latest update from the VMWare Web site and what is the best way to install updates?

  Thank you

  The best way is to connect ESX to VC and use the Update Manager.

• vCenter and host communication SSL v3

  Hello

  Can someone tell me why a vCenter Server Windows would communicate with a 5.5 on TCP/443 ESXi host using SSLv3 (in particular)?

  If you search Google for "kb2093354" titled "VMware KB: disable encryption on the server vCenter SSLv3" which seems to be what I want, it is no longer available, does anyone have an updated link to day for her?

  According to the Documentation centre, 443 is the WS-Man/HTTPS port and is a required port, but how to disable support for SSLv3? I don't want to tell browser to vCenter for admin, I mean ESXi host to vCenter

  Thank you

  I can confirm that vCenter 5.5 (U2) communicates with guests (5.5 U2) via SSLv3 only, the reason being vCenter only support SSLv3 in his original SSL Client Hello packet when connecting to an ESXi host:

  

  Note: Taking communication SSL/TLS between agents vCenter and vpxa on hosts always is launched from the process of vpxa.exe of vCenter acting as the Client that connects to port 443 of a host and not the other way around (which caught vCenter protocols supported on port 443 is not relevant).

  ESXi supports TLS1 with SSLv3 for long, and since ESXi 5.5 it comes from the tree of openssl 1.0.1 libraries that support TLS1.1/1.2, which can be confirmed from a host:

  # openssl s_client-connect [insert here the ESXi host name]: 443 < ev/null="" 2=""> 1 | grep 'SSL-Session' - A2

  SSL-Session:

  Protocol: TLSv1.2

  Encryption: AES 256-GCM-SHA384

  I suspect that the configuration changes must be made to the vCenter Java application so that the Client sends a TLS version in the handshake Hello. When I lanuch the Java Control Panel on the vCenter via the command below I can see SSLv3 and TLSv1 are supposed to be enabled, but the negotiation Client Hello sent by vCenter to the SSLv3 Client only:

  Com.sun.deploy.panel.ControlPanel - Xbootclasspath/r: "c:\Program Files VMware vCenter Server - Java Components\lib\deploy.jar" "C:\Program Files\Fichiers VMware vCenter Server - Java Components\bin\javaw.exe"

  
  

  It is probably crashed somewhere in the application and I have not tried to disable SSLv3 here since I do not have a currently available test environment. in any case, it would be well if VMware is completely removed this KB article either open to the public instead of saying:

• ESX host keep disconnecting

  I installed Workstation 7 on my laptop and then I installed ESX4 and I installed Win 2008 Server DC and XP as a client, it is a small network within the workstation 7, I installed vcenter on xp. I added host esx to vcenter, but very often disconnected ESX I got an error to the vSphere client "host not responding not not in red. the resolution of all the names are very well each other, each machine can ping IP as hostname.  no firewall, by default, all ports are

  Please see attached screenshot of vcenter client and these two ESX host event log

  No idea

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

• Exhausted ESX host memory

  Hi guys

  I have a few 3.5u4 ESX, basically it's a Desktop Virtualization infrastructure.

  ESX hosts 32 GB of RAM

  They are now around 250 VMs on host virtual machines 40-45.

  Lately, all ESX hosts trigger alerts to RED, VMs are set at 2 GB (which I think is too much for simple office applications).

  Apart from checking if all have tools Vmare, btw how to get the latest vmware tools for virtual machines on esx 3.5?

  What else should I check on the VMS and to know why they are exhausting memory to host ESX (more than 90% of use)?

  any idea is welcome

  Thank you very much

  At the first glance, I must say that you yourself have built a time bomb.  It will explode at some point.

  The problem is, as you seem to indicate, that you have massivley on subscribed your memory.   More than 2:1.  Office workloads are difficult to anticipate.  Giving them a lot more overhead is just asking them to use it.   I know there are probably people who never use more than 250 MB of memory.  However, today it is not difficult to chew a lot more.   I know that my office, I am granted more than an "advanced user", it runs generally in the range of 1.5 to 2GB.   It is not really a way to control this in part to limit the available memory by VM or implementation of resource pools to manage.

  With regard to your specific questions.   How do you determine the versions of vmware tools?   Is not difficult.  Within the virtual Center, select the host resource or a cluster.   Then select the tab "Virtual Machines".   If it is not already displayed, right-click on one of the headings at the top of the columns.   This will bring up a menu of the available to display columns.  Select "VMware Tools Status.   This will then give you a column when you view virtual machines which indicates if the virtual machines are up-to-date with the latest version of the tools.  This will not give you specific versions.  But it will give you an idea of what day and what is not.

  Take a look at some of the other available columns and add those that make sense.  There are fields for the declaration of use of the memory.    Add them and look to see who use virtual machines the most memory.   You will need to check each of them and talk to your users to know what they are doing which requires many resources.

  You're in the political game at this point.  Have fun!

• Long distance vMotion, vCenter on 6.0, hosts on 5.5

  Has anyone tried this and is this still possible? We are in the middle of all our sites with a new architecture VMware 6.0 refreshing and a big reason is that we want to use vMotion long distance to migrate workloads as we slowly consolidate form 3 to 1 data centers. So far, we have deployed a device VCSA 6.0 and 2 MCS in 2 data centers. We have not yet upgraded 5.5 still hosts.

  I'm not request anyone to test this in their environment or to do our work for us, since we are in the middle of the project and the work that I type, looking for feedback as I'm sure that someone else has tried this scenario in the wild before and well that my google-fu did not surface this answer again. I'm just curious to know if you need to upgrade your managed host of esxi 5.5 computers. 6.0 to perform the vMotion improved long-distance over WAN using link lniked mode OR if the vCenters being on 6.0, added in the same domain SSO and improved bound mode is enough. We would be able to ignore the upgrade about 25 guests because we have not deployed yet VUM so fingers crossed.

  Thanks to anyone who can provide comment to my first question of communities.

  You move between vCenter also? If so, the hosts of ESXi and vCenter must be at version 6.0. See the requirements on the cross vCenter vMotion: Cross vCenter Server VMware vSphere 6.0 vMotion requirements (2106952). VMware KB

  To enable the migration through the server vCenter instances, your environment must meet these requirements:

  • The source and destination and ESXi hosts vCenter server instances must be running version 6.0 or later.

  Anyway, you can upgrade one host in each vCenter and use this host to start the migration.

• 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.

• VCenter and host ESX upgrade details

  Hello

  When I run vmware - v on my esx host. I see the output as VMware ESX 4.0.0 build-208167 and my vcenter Server 4.0.0 208111 watch and I want to VC\ESX 4.0 Update 2. When I check the upgrades for ESX 4.0.0 build-208167, shows me the build under ESXi (Embedded and installable) and not under ESX. A little confused but is that correct? The latest version is also "Build number: 660575. Can I directly go here? What is the process?

  Please notify

  1. so my hosts are now on the ESX update and version number, by following your steps would take them to ESXi last updated and build number which is simply the next last update of level and the patch level. What is the correct interpretation? We call this an update or upgrade?

  > the steps I mentioned will bring the level of the last update, IE ESX 4.0 to ESX 4.0 host update4... Do NOT ESXi.

  2. What is the right approach to find the last bet to day and the patch level, given my example so that I don't have to bother you guys again in the future.

  > Keep track of VMware patch portal http://www.vmware.com/patchmgr/download.portal

  Select the product ESX and version 4.0.0 and do a Search. It will list on the latest patches and updates released. You can check with the dates or numbers of patch.

  3. According to the steps you provided, do I just download the Update Pack and patch at one of the warehouses of data that is submitted to these hosts and then run the command of esxupdate course after first having the server in maintenance mode?

  > Yes

  4. is there a separate procedure for updating the vCenter Server also?

  > For vCenter, you need to download setup vCetner for 4.0 update 4 and run the installer.

  Please go through vSphere 4.0 Upgrade guide for details.

• Migration 4 and 3.5 ESX hosts again vCenter Server 4.0

  I'll put up a new vCenter Server 4.0 with an Oracle database to take the place of two vCenter using express databases included. They are both on the hosts recommended 5-50 VM for the Express database, oops.

  The first is vCenter 4.0 which uses the express database included is on a Dell 1950 server. ESX 4.0 hosts are on 2 groups on Dell blade servers that have 5 blades per cluster and are using storage arrays EqualLogic iSCSI for data warehouses. More there are a few individual Dell R900 and Dell R710 servers use local storage connected to the vCenter.

  The second is vCenter 2.5 that uses the express database included running on a Dell 2950 server with, like 20 other Dell running ESX 3.5 of 2950 using local storage.

  Looking for a vision a little and advise the host migration to the new server vCenter Server.

  Thank you... Jim Hurley

  I would say the easiest would be to create new vCenter new host OS (I would choose 64 bits that will put you in the conditions required for 4.1).  Once the new vCenter Server online, I then install a standalone license server for your VI3 hosts, then begin to disconnect and remove other environments and new hosts.

  Stand alone license server can be found

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