• Change the path information for ESX ESXi hosts to access

  Hello all! I hope you guys can help me.

  I have about 47 hosts that I need to change it Round Robin storage path information. If I make the change in vCenter and restart the host it again changing fixed. So, I thought that I should change it to the level of the host through esxicli.

  I have about twice as many LUNS of the Hitachi SAN. I'd like to see if it is possible to make the change in all areas, in some way, or I need to make the change by host? Also, is there anything that I need to change sides San so that it works or not.

  I saw this VMware KB: modification of path information for ESX/ESXi hosts to access and assume that it is the best plan? But did not know of all put into custody, if necessary, that everyone ran to when doing this?

  You will need to make the change by the host and the KB you'll find is the right method.

• Disable communication between the host and the virtual machine

  I have VM Server 2.0 and one of the virtual machines has the same name as the server and even if the virtual computer is connected to the host only network it generates the Windows error message: duplicate names exist on the network.

  is there a way to disable communication between the host and the virtual machines? I just need a virtual network that is isolated from my network complete and host also.

  Thank you.

  The GUI Server2 is not to choose the other unused vmnets.  Then edit your file VMX use a different vmnet of 0, 1 or 8.  (which are bridged, host-only and NAT)

  Thus, for example, if your VMX has a line that says:

  Ethernet0.VNET = "VMNet0.

  change to:

  Ethernet0.VNET = "VMNet2.

  (This assumes that you have not used the network Editor to fill the vmnet2 either).

• Monitoring selected VM, ESX, cluster hosts

  Hello

  I check if it is possible to select the specified ESX host or Virtual Machines to monitor instead of pulling all the VMS and hosts in Foglight? Thank you.

  Kind regards

  Jamie.

  You can via a user name, but we do not support that.  The problem lies in the case you have a virtual machine, and then you forget about the potential problems with the host.  If you have only a few hosts, it could miss part of a cluster or something else using the storage...  There are many cases where not having not any data could cause problems, so we don't support all a vCenter.

• Communication between two hosts on the host only

  I have a host ESXi 5.5 with two reviews, a Linux / Centos 6.5 comments and a guest Server R2 2012.

  I've muddled through many questions - time zone, being the biggest problem, but am confused on how to get these guests to see one another, not even sure what to put in Google.

  My goal is to be able to share files between the two guests and access their consoles with putty and RDP, but I can't make them one ping to another. Everyone on the LAN can connect these two guests, but they cannot see.

  A kind soul told me that I forgot?

  Thank you

  Hey katycomputersystems,

  Could you give us a quick screenshot of your vSwitch / Port groups.

  Of the IP information you should be able to ping to each of the systems if they are on the same vSwitch / Portgroup / VLAN.

  Try this

  vSwitch0

  VM Network - Port Group - VLAN 110 - physical Nic don't matter we will keep all the VMS on this port group

  Configure all your VMS on the port network of VM group.  As long as all the VM living on the same port group vlan and vSwitch traffic should never leave this vSwitch and each VM must be able to communicate with each other.  If not you can always ping each other take off the VLAN and try again.  Make sure also that you have no firewall or tables ip enabled on the operating systems that could prevent communication.

  Let us know how it goes

• Lack of communication between the host computers

  Hello

  We have a small installation demo (2 x ESXi5.1 build 799733 hosts) of vCloud Director 5.1.1868405 running build and meet a strange communication with the VMS problem when they sit on different hosts.

  That we have tested with several organizations and different types of OS etc and the behavior is the same, an example would be that if one of the VMS is a Web server of the site can be displayed if from VMs on the same host, however when you separate guests cannot view the Web site. Virtual machines can ping each other wherever they are.

  I hope someone here can help point me in the right direction to solve this

  Thank you

  Looks like your pool of network is down.  If you are using a paralytic, routed Org or Org... isolated network looks that transport between the two does not work.

  If virtual machines are on one of these network types and on the same host, it works.  If they are on different hosts, it fails.

  Is what kind of network pool?  VCNI, VXLAN etc.?

  Make sure that the physical network is actually configured to transport data.  for example, VCNI uses a VLAN and MTU to 1524 (suggested min) for transportation between the hosts.  However, you need to configure it on the fabric of network (switch, etc.).

  VXLAN has its own requirements, but it has a way to test the virtual wire.

• Objective 7.1 - guarantee the issue of ESX/ESXi hosts

  Hey all,.

  I am currently working on my study guide for the DCA review and have fallen somewhat with the ESX/ESxi Secure objective 7.1 hosts and more specifically the section for "Customize SSH Seetings for increased security. The only documentation I could find about it is in the "ESX Configuration Guide" on page 202 and the VMware KB 1017910. In ESX config guide details how to REDUCE the requirements of security on default (allowing root access, change the version of the SSH protocol, etc.), and the article explains how to set a timeout for the technical support of Mode (both local and remote). I guess these aren't the types of answers they seek, as the section is to increase the level of security.

  Any clarification or possilbe advice that anyone could offer would be greatly appreciated.

  TIA,

• Cluster of RAM available vs ESX or host available RAM systems

  I downloaded ESXi 4.0 to play with HA and DRS etc on some not very new material that I managed to combine. I have two hosts ESX, Virtual Center and a NAS box.

  Unfortunately, the ESX hosts have only 2 GB of RAM each.

  When I put the hosts in the cluster and look at the resources available cluster I don't have that 319 MB of RAM available - even if there is no virtual machines running.

  Each ESX host has more than 1 GB of RAM available - I wonder what the circuit breaker is here?

  This apparent lack or RAM means that HA does not have enough resources to set up a HA cluster for example...

  ESXi 4 requires 2GB for himself. In fact some less than 2 GB, but make sure it as a starting point.

  All the memory you want to give the virtual machines - should be greater than 2 GB.

• Using Get-VMHost connected to an ESX vs. host connected to a VirtualCenter Server

  Hello

  The script here returns a list of paths storage dead but only works when you run against an ESX host. How can I adjust it to report on all ESX hosts, managed by a VirtualCenter Server?

  $vc = Read-Host "enter the name or the IP address of your server VC."

  SE connect-VIServer-Server $vc

  Get-VMHost | Get-ScsiLun | Get-scsilunpath | Select Lunpath, Preferred SanID |

  where {$_.} SanId - ine $null - and $_. State - eq 'Dead'}

  Disconnect-VIServer-confirm: $false

  I guess this is a loop in the sense of 'ForEach' ($VMhosts in Get-VMHost), but have been unable to come up with the appropriate syntax.

  Any suggestions?

  Thank you!

  The following script will display the properties in the HTML file, as in the first script.

  Shaped more away from the exit (separation of the column, frame, color...), you will need to use the HTML formatting.

  
  $report = @()
  Get-VMHost | Sort-Object -property Name | % {
       $server = $_
       ($_ | Get-View).config.storagedevice.multipathinfo.Lun | % {
            $preferred = $_.Policy.Prefer
            $_.Path | where {$_.PathState -eq "dead"} | % {
                 $row = New-Object System.Object

                 if($_.Name -eq $preferred){
                      $IsPreferred = $true
                 }
                 $row | Add-Member -memberType NoteProperty -name Preferred -value $IsPreferred

• VMotion and file on an ESX Server host

  Hello

  We have recently implemented 3 ESX 3.5 servers and configured HA and Drs However, I wonder for VMotion to work correctly, each ESX Server dns name and IP address must be in each box of ESX host file? My last company consultant put all the names of the ESX servers with IP addresses in the file for each host, but this time, the consultant does not. I was wondering if it is advisable or not?

  Thank you.

  KeV

  Hello

  You needn't name resolution for Vmotion. This is based on the Vmotion network, that use only Ip and default gateway addresses.

  On the hand of oter HA need DNS to work. Then you should be able to resolve host names in the bu cluster HA FQDN.

  Have a look here for best practices on HA-> http://www.yellow-bricks.com/2008/10/27/ha-best-practices/

  Best regards
