• new to vmware, vsphere and networking vswitch

  Hi all

  I am new to virtualization, but decided to try it since my company is going full on ESXI5.5.  That is why I hope that some kind gurus here can point me in the right direction regarding some doubts I have... and do not forgive me if I ask ridiculous questions...

  ==========

  So far, I know that VMs, through their vNIC connect to vSwitch which is in turn connected to the physical machine or the host ESXI (vmnic) network card. The vmnic is then connected to a real L2/L3 switch.

  [VM Vnic] <>- [vswitch] <>- [vmnic] <>- [physical switch]

  However, what I don't understand is how the vmnic actually works to spread the traffic "inward" to the vswitch? I can't really come up with one question to explain my doubt, but below are the doubts that I asked myself->

  • How is he able to assign the IP off the internal virtual machines?
  • When an outer package of the physical switch is being sent to the vmnic how he spend in-house for internal virtual computers?
  • How even knows designated IP belong to a virtual machine inside and "inward" to happen to the vswitch?
  • Is the vmnic using address IP or MAC to decide if it means putting the package inside the switch?
  • When an arp request for a virtual machine IP is send from the outside, the vmnic will reply with its mac address?
  • When an arp request is sent from an internal virtual machine, the vmnic keep track of the mac address of the virtual machine so that next time, when he saw a response to this MAC, he knows inside 'before' the vSwitch
  • What is this work something like a 'bridge' mode fill the vswitch internal to the external physical switch? Is there a table of addresses belonging to the vmnic mac?
  • Whenever the IP of the virtual computer is assigned, the IP address will be "bind" to the vmnic?
  • How register us all IP or Mac addresses (if any) that are associated with a vmnic?

  Or rather simply, I wonder how the physical network adapter on the host (esxi), knows that he must transfer a frame "inward" to the vswitch? is there a link OF the virtual machine to the interface? or nic was a table of addresses mac or something... (but the mac address table guess belong to vswitch?)

  Thank you.

  Kind regards

  Hello

  Welcome to the community!

  I would like to start with a doc. I recommend you to read our VMware Virtual Networking Concepts guide that I hope will help you to better understand the basic details of the virtual in VMware switch, even if it's a bit old.

  On your last question, however:

  > Or rather simply put, I wonder how the physical network adapter on the host (esxi), knows that he must transfer a frame "inward" to the vswitch? is there an IP link from the virtual machine to the interface? or nic was a table of addresses mac or something... (but the mac address table supposed to belong to vswitch?)

  The vminc (i.e. the physical card) on the ESXi host is not that there is a virtual switch behind it. It transfers the packets to the driver and then the top layer software it management. There is no magic to this topic. In some cases, there are a few added techniques (for example netqueue), but the basis remains the same. Vmnic (i.e. the physical NETWORK adapter card) does not keep the information of MAC address of the virtual machine on virtual machines, but does the vSwitch. But even the vSwitch does not retain details of the IP address.

  A virtual switch, as such, doesn't have the same kind of as a physical switch mac address table. If a virtual machine under tension then the vSwitch stores the virtual port <->combination MAC address number and keeps it like that (so far it's really no different a physical switch). A big difference is that, well that the vSwitch does not learn the MAC addresses of the external network. If there is a picture of outside with the MAC address of unicast for which there is no port isn't linked then the packet gets dropped. And if the virtual machine sends traffic to another MAC that does not exist in the virtual switch and then it will be sent out via the uplink (s) (if it exists).

  The MAC address of the vmnic does not play here (unless one of the vmkernel interface pulls his MAC to an adapter of uplink).

  I hope this helps. Let me know if you still have any questions.

• I have a new server and you cannot use Remote Desktop connection.

  I HAVE A NEW SERVER (HP ML110 G6) AND HAVE USED OLD HARD DISKS, BUT MY REMOTE DESKTOP CONNECTION WILL NOT ME OR OTHERS - WHAT COULD THE REASON BE?

  Hello

  I suggest you to try the steps below and check if it helps.

   The problem can also be caused by your security such as anti-virus program or a firewall of Windows /Defender that can have conflicting parameters as to not not to perform certain tasks. I suggest you temporary disable antivirus and firewall and check the result again. You must activate new security that you was disabled programs.
  Disable the antivirus software:

  http://Windows.Microsoft.com/en-us/Windows7/disable-antivirus-software

  May also need to do this on other computers as well.

  Important note: Antivirus software can help protect your computer against viruses and other security threats. In most cases, you should not disable your antivirus software. If you need to disable temporarily to install other software, you must reactivate as soon as you are finished. If you are connected to the Internet or a network, while your antivirus software is disabled, your computer is vulnerable to attacks.

  Hope this information is useful.

• Error Windows Store"we were not able to connect to the Bank. This could have happened due to a server problem or network connection has expired. "Please wait a few minutes by trying again.

  Original title: store Windows and Microsoft Services does not

  I tried for awhile to update to Windows 8.1, and whenever I open the Windows store, I get the following message:

  "We could not connect to the Bank.  This could have happened due to a server problem or network connection has expired.  Please wait a few minutes by try again. »

  I looked through a large number of subjects and lived simple solutions, like check that the time is correctly synchronized and clear the memory cache to store.

  Just today, I found another solution posted, to make my computer trusts.  To do this, I had to connect my local account to my microsoft account, I tried to do, only to be met with the following message:

  "Sorry, we could not connect to the Microsoft services right now.  If the problem persists, look for "referee" in the start screen. »

  I did the research you suggested, and nothing came.  When I watched this show online, I found the idea of creating a new user account, which has been received with the same question.  The suggestion of other involved running a diagnostic tool for Microsoft account who investigated the issue, which has turned a few 'problems found', namely an Unfixed 'Problems with the strategy of Microsoft account' and a Detected "Rootcauses found and created newspapers", but this is not what that means, or how to solve.

  In addition, some of the suggested solutions were an antivirus program, but I do not have a third part of the installed antivirus program.

  Any help is appreciated, because I really want to solve this problem.

  I had this problem too. Here is how I fixed it in about 3 seconds.

  1.) by scanning in the right and type "WSReset.exe" (without the quotes) in the search bar.

  2.) click on the application that appears. It will look like a Windows Store icon.

  BAM... done. I hope this helps!

• upgrade to vCenter on new server

  Hi all

  We currently have:

  A: Server vCenter current 5.5 with database on server b.

  Server B: vCenter SQL database

  C: brilliant new server

  We would like to do:

  Server: old 5.5 vCenter (not in use, stop)

  Server B: Server SQL database vCenter (same database as before, just upgraded to 6)

  C: Server vCenter 6.x with the same database on server B as before

  So what we want to do is to simply install vCenter 6 on the new server and point it at the existing database during the installation. Can you let us know if it works please? Otherwise what paths are available for us please (installation of 5.5 to the new server, pointing to the existing database, and then in place upgrade to 6 for example).

  See you soon.

  Hello

  VCenter installation costs 6 and that it points to a DB vCenter previously used for 5.5 will fail with the error of the incompatibility of data base (daily if with VMware support)

  What you need to do is:

  Server c: fresh installation of 5.5

  Perform an upgrade on the spot of 5.5 to 6.0 using the external DB. The DB is automatically promoted to VC6 compatibility during upgrade on site.

• The steps required to perform a migration to a new server vCenter using distributed switches?

  We are currently on version 5.1 of vCenter and ESXi 5.1 on all our guests.  We use a vDS on our current server vCenter and will need to migrate to a new server vCenter soon.  Is there a documentation about the steps to migrate to a new server vCenter using switches distributed?  We hope to achieve this goal without any downtime.  The problem is that we need that VDS on our 10GB network for the aggregation of links.  If having to migrate guests at standard switches before moving them to the new vCenter server, there will be problems of network performance.

  Because information about your environment are stored in the database of vcenter al you should just be able to stand up the new vCenter server and that it points to the existing database

• VMwareTools on error 3.11.10 - 100.fc18.x86_64 Linux while running vmware-config - tools.pl

  Implementation with a new VM FC18 on a host Windows 8 I can't get shared folders to work. After investigation, I noticed that vmware-config - tools.pl runs without error, except for the following:

  Using 2.6.x kernel build system.

  I've been struggling with this for awhile and I really appreciate all or hunting for a solution. Thank you.

  To answer my own question; I had to reinstall my kernel-devel package to make it work:

  [promp] t # yum reinstall kernel-devel

  [quick] # cp /usr/src/kernels/3.7.2-201.fc18.x86_64/include/generated/uapi/linux/version.h /lib/modules/3.7.2-201.fc18.x86_64/build/include/linux/

  [quick] # /bin/vmware-config-tools.pl

  And now my shared folders work!

• movement of virtual machines on new server

  I'm fairly new to vmware and operate a very limited plant, but would like assistance.  I have the Essentials package and ESX 4.0 is running on a single server with the virtual machines stored on local hard disks.  I installed a new server ESXi 5.1 and local storage, and I need to move the virtual machines from the old server to the new server.  If it's important, the guest virtual machine operating system are a mixture of linux and windows.  What is the best method to move those VMs?

  Hello

  If you have the two host added to vCenter, you can turn off VMs and migrate virtual machines to another host and data store.

  Since you do not have a shared storage, you must turn off VM to change host and the data store.

  It doesn't matter what OS you are running on a virtual machine.

  Thank you

• Migration of VCenter 4.0 to 4.1 on the new server - database upgrade problem

  Hello

  I am trying to migrate from a 32-bit W2K3 vCenter Server 4.0 to 4.1 running on a new server W2K8 R2.

  The servers have different hostnames and IP addresses.

  The datamigration tool ran on the existing server and registered the relevant question of config. I run it on the new server, and he acknowledges that there is data on migration and launch the installation program. This will go through the first steps and connects successfully to the db SQL 2005 (which is on a separate machine) via the DSN. Then, it generates an error:

  "vCenter server does not support the upgrade of database version 2.5u5 or below." Please upgrade the database to a supported version and try again".

  Thus, the vCenter database is in an old 'format '?

  How can I update manually?

  Thank you very much

  Welcome to the community.

  VCenter 4.0 DB is different from 2.5, for its strange.

  Check the DSN configuration if you point to the correct DB.

• New to VMware and Exchange 2010

  Hello

  I'm new to VMware and have some questions about the installer.  We just bought a HP DL380 G7 server and Exchange 2010.  I want to virtualize this server with a BES.  I'm trying to understand the best way to proceed.  We also have a Dell EqualLogic iSCSI SAN (PS4000).  Wouldn't it be better for me to boot from SAN and have ESxi installed on the SAN?  Or would it be preferable for ESxi installed on the server and have my VM hosted/installed on the SAN?  Thanks for the help.

  Hello owblueiii,

  I almose same infrastructure such as this, when I started the virtualization process was confused in this place, finally, we kept the boot on local, VMs oniSCSI SAN.

  advantages: 1. because if you have any questions you can the Como.

  2 and also a little difficult to troubleshoot if you have the on iscsi san boot partition.

  3. you can register your vms on san iscsi timing if you want the new ESX installation.

  Hope it's useful to your question.

• new to vmware - question

  Hi all, I'm new to VMWare and you want to ask a silly question. My project plans to use vmware on a single physical server running windows 2003 to implement multiple instances of servers windows 2003 virtual. My question is what do we need to have different IP address and host name for each server virtual windows? Or vmware manages to solve this problem itself? If so, how does this work?

  Thank you!

  guys, thanks for your reply... as you said, we need differernt IP addresses for each server, which makes it easy for us becase that means that we must go through a long process to the commission, the servers with the new ip address...

  If you had multiple physical servers, you will need to go through the same exact process. How many servers you plan giving each server an IP address is a big problem? VMWare removes just your need more physical servers, what you do with the guest computers is pretty much unchanged.

• Problem after moving to new server vCenter

  I moved vCenter to a new server by following this article:

  http://KB.VMware.com/selfservice/microsites/search.do?language=en_US & cmd = displayKC & externalId = 5850444

  After editing the file vpxa.cfg with the new IP of the vCenter server and restart management services, all of my guests are still disconnected.  I tried to select "Connect" from the menu, which has been connected to the host.  However, HA not properly configures.  Has anyone seen these symptoms after moving to a new server vCenter? Ideas for how I can fix the problems?

  More details can be provided according to the needs

  Thank you

  Jeff

  Is / was enabled on this cluster HA?  Have your tried to disable HA on the cluster, and once that all your hosts have been added to the rear allowing HA again.

  In addition, even if you did, you can restart the agents once again all hosts in the cluster
