What ports to use between the server host and ESX license
Hello
I've implemented a standalone ESX host and want it connects to the license server.
Is there anyone knows what port must be open for the connection from the host ESX to the license server?
Thank you!

Hello
I am developing an ESX solution, and because of the budget and space constrants just gave me a single server. I installed ESX 4.0 on this server, and then I created virtual machines that have become the ESX 3.5 servers. I was able to raise virtual machines to power and run in the nested virtual machines. My problem is, now I'm developing a solution ESX 4.0, but we use Windows 2008 64bi. Does anyone know how to get a host internal 64-bit to be able to run on an ESX 4.0 host externally.
Here is a small representation of the environment:
Physical box ESX 4.0
-Virtual Server ESX 4.0
-Nested virtual Windows 2008 64 bit server
Does anyone know how to get the 64-bit of Windows 2008 Server to run on virtual server ESX 4.0. I've already activated VT on ESX 4.0 virtual settings, but I can't find a place in the Virtual Machine BIOS to enable VT any help would be greatly appreciated.

Post edited by: Kirizan to the difficulty of setting in the form
Material assistance (VT) is not virtualized. Thus, nested virtual machines cannot be 64-bit and is the reason why you don't see VT options in the BIOS of the virtual machine .
If I read you correctly, you have ESX4 installed on bare metal and you have ESX 3.5 VMs. Now that you are trying to create a virtual machine in 64-bit Windows. You can create them in the ESX 3.5 environment. You must create a virtual ESX4 machine. (IOW, not nested).
In addition, after you enable VT in physical BIOS, you must turn off the physical machine. (Not just restart. (Power off).

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.

Problem setting MTU to 9000 on the ESX host and guests
I just set the mtu to 9000 on the ESXi host.
Then I changed the MTU to 9000 on the linux hosts.
The network fails.
This should not be supported?
vmk0 networking fe80::a236:9fff:fe3e:cbcc 64 a0:36:9f:3e:cb:cc 1500 65535 true IPv6 STATIC, PREFERRED
Looks like your vmk0 is to use IPV6 insist of IPv4, you can try to disable IPv6 in your vmk0?

Closing of the ESX host and conduct reviews
Hello
What happens to guests when the ESX4 host will be via vCLI command. Is the powerdown for the guests, save or critical?
Kind regards...
Wiwa53
You must configure this on "Configuration > VM works / stop" option. You can make a different policy for each virtual machine or one for all.
Through the vCLI are as you have made a stop in the vSPhere Client, so the system VMs will follow the order you configured in the configuration above.

Grant Web access to the only vm on the esx host
I have read the Administrator's guide and spent a few hours online on this subject and other types of users doing the same thing...
I have 2.5 VC and ESX 3.5 by running very well. I want to give web access to a virtual machine #1 running on ESX #1 host in this species, using the URL for the console "generate".
I went VC and granted permission to the user of the Virtual Machine to the particular user I want to access the virtual machine. I granted this permission to the esx host and the virtual machine. When the user attempts to connect (this is a domain account) they get the connection failed due to bad user name or password. It seems that the only account that can connect to web access is the root on this esx host account. I am at a loss here, because I also tried to set this user as an administrator and so on. The only account that can connect to web access, is that the account root localhost.
What I'm missing here?
The user attempts to access Web Access to the ESX Server? Which is what I think they do because without a third party tool they will be able to authenticate users who are in the service console, including the roots. If they try to access Web App of VC by pointing a browser VC while they should AD credentials to access their virtual computer.
Another thing to remember is that permissions in VC only apply when you log in to VC

How to balance IO SAN controller between my ESX host?
Hello good community.
Question about SAN controller i/o balancing between my ESX hosts.
I've identified the controller A and B controller on my SAN, HP EVA 6100.
The controller has 50001FE1 500E1208
Controller B 50001FE1 500E120C
But when I go to "Storage adapters", then "Manage paths" by vmhba and I'm lost. Policy of LB is fixed. Then I see:
vmhba1:0:6 50:00:1f:e1:50:0e:12:08 * status: active, preferred
vmhba1:1:6 50:00:1f:e1:50:0e:12:0 c
vmhba2:0:6 50:00:1f:e1:50:0e:12:09
vmhba2:1:6 50:00:1f:e1:50:0e:12:0 d
If the first two on my controllers, don't know about the bottom two WWWN however, can someone who knows HP EVA help here.
Also, I am very confused regarding mirrored ports and the need to be cautious when balancing the way between the controller.
Which would be great if someone could give me a few white read books on it, the same and also fair knowledge base articles explain how to approach the above and examine the virtual machines as well.
Not too big so... just small forum post I raised here... It will be useful someone help to get a dialogue going.
What I do with my EVA, is having different LUNs (Datastores) manually selected a path preferred in command mode. For example LUN 1,3,5,7 are on path then that lun 2,4,6,8 are set on Channel B. This means that all your LUNS are also responsible. On the ESX side each of my machines has 2 HBAs each with 2 paths that it looks like your Setup. Here's what I think looks like load-balanced:
ESX01-
vmhba1:0:6 50:00:1f:e1:50:0e:12:08 - LUN 1.2
vmhba1:1:6 50:00:1f:e1:50:0e:12:0 c - LUN 3.4
vmhba2:0:6 50:00:1f:e1:50:0e:12:09 - MON 5, 6
vmhba2:1:6 50:00:1f:e1:50:0e:12:0 d - MON 7, 8
ESX02-
vmhba1:0:6 50:00:1f:e1:50:0e:12:08 - MON 5, 6
vmhba1:1:6 50:00:1f:e1:50:0e:12:0 c - MON 7, 8
vmhba2:0:6 50:00:1f:e1:50:0e:12:09 - LUN 1.2
vmhba2:1:6 50:00:1f:e1:50:0e:12:0 d - LUN 3.4
It might not even be necessary have a configuration of blancing of load complicated if you produce not enough IO to saturate your current configuration. You can just keep it like this:
ESX01-
vmhba1:0:6 50:00:1f:e1:50:0e:12:08 - LUN 1.2
vmhba1:1:6 50:00:1f:e1:50:0e:12:0 c - LUN 3.4
vmhba2:0:6 50:00:1f:e1:50:0e:12:09 - MON 5, 6
vmhba2:1:6 50:00:1f:e1:50:0e:12:0 d - MON 7, 8
ESX02-
vmhba1:0:6 50:00:1f:e1:50:0e:12:08 - LUN 1.2
vmhba1:1:6 50:00:1f:e1:50:0e:12:0 c - LUN 3.4
vmhba2:0:6 50:00:1f:e1:50:0e:12:09 - MON 5, 6
vmhba2:1:6 50:00:1f:e1:50:0e:12:0 d - MON 7, 8
Hope this helps

Is there a tool available that can control the ESX host disk space on a daily basis? I was monitoring manually by typing df - h, but having more than 25 guests is tedious, so I wonder if there is any tool available which can monitor the disk space on the ESX host? Thanks in advance.
Check cela http://bash.cyberciti.biz/monitoring/shell-script-monitor-unix-linux-diskspace/, put it in the crontab and run it as offen, as you want.

Hello
Is it possible to move configurations of lab manager between the ESX server host computers / data warehouses? I don't see an option in the library & gt; Clone library. Thank you!
Recently, I used SSMove to migrate our datastore LM set a new LUN. It's really simple to use. This KB gives complete instructions on SSMove http://kb.vmware.com/selfservice/microsites/search.do?cmd=displayKC&docType=kc&externalId=1006694&sliceId=1&docTypeID=DT_KB_1_1&dialogID=8456583&stateId=0%200%209407965

How to report the current time on the ESX host in to a csv file with the following
Hello guys
I have the script next where I make the required details except the current time on the ESX host. Anyone can guide me please.
{foreach ($esx to $vmhosts) $hostVC = $vcenter $hostCluster = $esx. Parent.Name $hostHost = $esx. Name $ntp = $esx | Get-VMHostNtpServer $hostNTP = "$ntp". } I want to integrate the following for loop of the above for loop and ge the output in a single table.
foreach ($esxcli in get-vmhost | get-esxcli) {"" |} {Select @{n = "Time"; e = {$esxcli.system.time.get ()}}, @{n = "hostname"; e = {$esxcli.system.hostname.get (.hostname)}}}
Add-Content - Path '$hostVC, $hostCluster, $hostHost, $hostNTP, $hostTime' $hostInvFile - $ hostTime is where I want to get my host right now.
I'm vcenter, esx name, name of the cluster, host of the ntp server address, but I need the host thus present.
Thanks in advance.
Thank you
vKar
Try changing the line where the script retrieves the VMHost to this
$vmhosts = get-VMHost-State connected. Name sort
This way the script will be only to ESXi nodes that are "connected".
Pick up time for those defective does not much sense in all cases

Check if the esx host is in maintenance mode
HelloI need to know if there is a api in java vi which can let us know if any of the esx host is currently in maintenance mode?
I know there is a way to discover this through the same monitoring using event Manager, I need to know is an api live which can let us know if the esx host is in maintaince at that precise moment?
Thank you and best regards,
Rachid chollet.
Hi rachid,.
I guess that the following property is what you are looking for: HostSystem.runtime.inMaintenanceMode
But watch out for the docs for the property when it reads it: it is not set during the entry phase of maintenance mode.
