vSphere 5.5 share with FREENAS not working

March 13, 2014, 11:53 am

Hello,

 

I am trying to setup a vSphere HA lab using vmware workstation. I have two vSphere VMs installed on vmware workstation running on my laptop and I have a third VM which is hosting FreeNAS for shared network storage. I have configured two storage in the FreeNAS and I am trying to add these storages to my vSphere VMs. But for some reason I always keep getting the error : NFS mount failed:Unable to connect to NFS server.

I am able to ping between the ESXi VMs and the NFS server. One strange thing I have observed is that when I try to " nc -z <nfs server ip> 3261" it usually does not give me any result. Which makes me think that there is some problem with the port being opened on NFS server. But then when I actually try to add the shared data storage using the vSphere client of one of the ESXi host and while that is trying to add the data store I also run the netcat command from the ESXi's cli and during that period it works giving me an output saying "connection to port 3261 succeeded!".

 

I am unable to figure out what is going wrong? Is there something wrong with my mounting on the NFS FreeNAS server, or if there is a communication issue between the two VMs. I tried to capture packets on my laptop LAN interface, but I think the packets between VMs dont hit the LAN interface? I dont see them there.

 

Please help me and suggest how I should go further with troubleshooting this issue.

 

Just an FYI, I am trying to implement the LAB described on this link.

 

https://www.simple-talk.com/sysadmin/virtualization/vmware-lab-setup---a-virtualized-lab-for-testing-ha-and-drs/

 

And the FreeNAS server I am using is ver 9.2.1.

Thank you.

but they never create Host records in DNS automatically. every time i have to create host records manually. 

am i doing something wrong or this is the only way to create Host records for ESXi 5.1 Hosts.

Can't ping esxi host from ubuntu guest vm

I need to get my ubuntu vm connected to the network. This is my first foray into using vmware and virtualization in general. I really have no clue what I'm doing here.

 

I have an esxi 5.5 server running bare metal on a xeon server, and using the trial version of vSphere client 5.5 on my Windows laptop I've created and deployed my first vm using an ubuntu 12.04 LTS iso image.

 

I've installed the vmWare tools using default setting on the ubuntu guest vm. It complained about no X support but seemed to install alright since the vmware-toolbox-cmd command seems to function.

 

The esxi server has an ip address of 184.164.130.34, and the network admins have provided the ip range 184.164.130.34 to 184.164.130.38 to use. So I configured ubuntu to use an ip address of 184.164.130.35.

 

What am I missing here? Must I assign that vm ip address 184.164.130.35 somewhere in the vSphere client?

 

Here is a picture of my network config in vSphere:

vsphereNetworking.jpg

 

Here is a pic of the vm's network adapter config in vSphere:

vsphereNetworkAdapterConfig.jpg

 

Here is the pic of the ifconfig output from the ubuntu guest vm:

here is the pic of /etc/network/interfaces:

here's what happens when I try to ping the host esxi server from this guest vm:

Hi there,

 

I have a vm (Solaris 10 32-bit) that I have recently removed the last hard disk on the second SCSI controller (LSI LogicParallel) but it won't disappear. There is nothing else connected to this controller. vMotion and storage vMotion of the vm did not clear it. Any ideas?

Core parking and CPU contention

October 8, 2014, 3:33 pm

My question is this. Does a parked vCPU core still need to be scheduled on the Host CPU?

 

I have Googled around a bit and I have certainly found quite a few differing opinions on whether or not it is better to disable core parking or leave it enabled, but I haven’t found an answer to this basic question.

 

I recently noticed on one of our Server 2012 VMs with several of its cores parked. The processor usage on this VM is variable. There are often times when the machine is not heavily used but when it is needed, it needs to be able to respond quickly and it needs all of its cores to do so. At times processor usage can go back and forth between 2% and over 90% quickly. During these time I notice the vCPUs parking and un-parking quite a bit and I know that, kind of activity can have an adverse effect on performance.

 

My first though was to simply shut off core parking in Windows to avoid performance problems at these times, especially since there is no power saving benefit for the VM, but then it occurred to me that if a parked core doesn’t need any resources from the Host machine leaving parking on could help with CPU contention on the host when the VM is idle. If, on the other hand, a parked vCPU still needs to be scheduled on the host CPU then there would be no advantage to leaving parking enabled and I should just set the power scheme on the VM to “High Performance” to shut off core parking.

 

So, does anyone know whether or not a vCPU core on a guest VM that is in a parked state still needs to have idle cycles scheduled on the host CPU?

proper way to configure vmdk virtual disk nodes?? 1:0, 1:1, 1:2, etc.??

Are 1:0, 1:1, 1:2 the correct way to designate separate controllers for different vmdk disks being added to the virtual server??

I know 0:0 is for the first system disk or C:\Windows drive of a Windows VM.

I am adding 5 separate VMDKs to a SQL server to partition off the data, logs, tempdb, backups and the nodes only go to 3:15...

 

Another way to put it what is the best way to allocate 3 remaining iSCSI controllers to different disks for a SQL server??

 

I was thinking:

#1 databases and logs and backups

#2 tempdb

 

Thank you, Tom

Using Jumbo Frames with 2 NIC Configuration

October 8, 2014, 4:09 pm
$

I was wondering if anyone has had any experience or insight with using jumbo frames on hypervisors that only have 2 10GbE NICs in each.   I was reviewing a configuration and saw that the MTU was set at 1500 across the board and starting wondering if they could even implement jumbo frames with only two NICs.   Now, as a disclaimer, I have quite a bit of experience with jumbo frames in other environments, but I'll try to explain why I'm wondering if it's worth trying.   The environment is up and running just fine with the help of some QoS/COS on the switches, but I'm just wondering if iSCSI, backups, and possibly vMotion (I don't want to start a debate about thisand jumbo frames though) could benefit from jumbo frames.   


Here's a breakdown of what each of the hypervisors (running VMware 5.5 update 2) network configs currently look like:

 

Standard Switch: vSwitch0 (1500 MTU)

  • Physical Adapters
    • vmnic0 10000
    • vmnic1 10000
  • Virtual Machine Port Groups
    • Production Network - VLAN 10
  • VMKernel Ports
    • vmk1 - iSCSI0 - VLAN 54 (1500 MTU)
    • vmk2 - iSCSI1 - VLAN 54 (1500 MTU)
    • vmk3 - vMotion - VLAN 53 (1500 MTU)
    • vmk4 - Management - VLAN 55 (1500 MTU)

 

Normally, I would have at least 4 NICs per hypervisor and separate the vMotion and iSCSI from the VMPG's and call it a day.   Then I would set the iSCSI vSwitch (and possibly vMotion depending on tests) to 9000 MTU while leaving the VMPG vSwitch at 1500.   Due to several reasons, this setup is limited to the two NICs per server for the forseeable future so adding NICs isn't an option right now as crazy as that sounds. 

 

My question is if I set vSwitch0, iSCSI0, iSCSI1, and vMotion to 9000 MTU, is this going to negatively impact the Production VM Network and the Management VMKernel ports?   Since these both fall under vSwitch0 which would be set at 9000 MTU, I'm somewhat curious if it would affect those even though they would be kept at 1500 MTU.  Would there just be no affect as this is completely dependant on whether the Guest OS NICs are set at 9000?  

 

Normally, I would just try it and see what happens, but this is in a production environment and I don't want to bring the entire infrastructure down.   So has anyone had any experience with this or have any advice?

ESXi 5.5 SSD Host Cache Configuration error

Hello colleagues!

 

I have small error with my two ESXi servers. They have ESXi 5.5 u2 version, different hardware, different RAID controllers and different SSD disc for caching. But both have the same error:

 

After SSD initialization all cache configuration worked good. But after some time I can't configure it from GUI because it 0 Gb for caching (see attached screenshot). If I physically disconnect SSD from host and format it, and connect it again - magic, I can configure it properly.

 

Do you have any ideas about this case?

 

Thank you beforehand

How to configure HBA settings for ESXi 5 Servers ?

Hi,

 

We are running ESXi 5.1 hosts on DELL Servers.  And we are using QLogic QLE2460 HBA. 

 

There is a recommendation that we should configure HBA as follow

1) Data Rate to Auto Negotiate

2) Connection Option to "Loop Preferred" and then "Point to Point".

 

From vSphere Client, I find that we can only view paths and change Path Selection (Like: MRU / Fixed / RR) only.

 

Is there any suggestion on how to check the HBA configuration ?

 

Thanks

Hello,

 

I am on esx5 using local datastores with plenty of space.  I am using Veeam Backup to back up my VM's.  Occasionally I will see a "Consolidate Helper -0" snapshot left behind on the VM.  It seems if I create a new snapshot and then delete all it will go away..  Veeam claims this is a VMware thing.  Any common knowledge of what could be causing this?  Thanks for any insight.

E1000 Bug for ESX 5.5

As you may remember we had E1000 related PSOD issue on ESXi 5.1, and VMware have patched it with KB 2059053

Now we upgraded to latest ESXi version we are having the same issue. KB 2079094

 

So my question to VMware now:

 

You have fixed this bug previously on 5.1, now why do we see same bug in latest ESXi 5.5.0 build 2068190 ?

 

This is the article for the bug currently there is no resolution:

http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=2079094

 

This is the bug they have fixed on early versions

http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=2059053


This is very unprofessional.

Hello community!

A few days ago, one of my servers got PSOD. Unfortunately, it was not possible to look at the message on screen and I'm hard reboot server via iLo. After this, server has successfully booted, but I would like to find the cause of the problem.

I was looking materials in the knowledge base on these issues, but I can't determine the cause. Maybe you tell me in what logs need to look and what to look for in them.

In vmksummary.log

2014-10-05T06:18:32Z bootstop: Host has booted. In the log there is no record about bootstop: Host is powering off.

hyper-v vm in nested environment

Hi everybody, I really didn't know where to post this question...in the event I have wrong the thread, please suggest me where to shift my post.

 

I need to set-up an environment for testing Hyper-v. Currently I have an ESX Server hosted in a VMware virtual machine (nested ESX) and the virtual machine is hosted on a physical ESX Server. I've already installed a Win2012 vm on that nested-host. Therefore the situation is the following:

Physical ESX Host -> VM with ESX installed -> VM with Win2012 installed

 

I've followed all the instruction in order to "emulate" the VT instructions:

 

vhv.allow = "TRUE"  on physical host and nested esx

 

and add the line in vmx of the win2012 vm:

 

hypervisor.cpuid.v0 = "FALSE"

mce.enable = "TRUE“

vhv.allow = "TRUE“

 

Currently I managed to install hyper-v and create a new vm in hyper-v management console, but the vm couldn't start due to unstarded hypervisor....

 

Any suggestion?

Host performance VM CPU legend - how to identify the VM?

Hi

 

On my vSphere, when I look at a host with a number of VM's running on it, and I go to the "monitor" tab, then "performance" and in "Advanced" rather than "Overview" and with "CPU" selected I see a graph and below it I see the "Performance Chart Legend" with a number of "objects" including the host and a number of objects (VMs) with just numbers on. Is there a way to easily and definitively associate the number with the vm name?

 

That is, my problem VM is "18" - how do I get the actual identity of that VM?

Enabling audio in a Windows Server 2008 R2 guest

I need to enable audio in a Windows Server 2008 R2 guest VM hosted by either an ESXi 5.0 and an ESXi 5.5 host.

If I create a Windows 7 guest VM on the same hosts and I access it via RDP audio works fine without any specific confnguration .

If I create a Windows server 2008 R2 guest VM and access it via RDP I get a message saying that no audio device is available.

How should I configure either the VM and the Windows Server 2008 R2 guest OS in order to make audio work?

I do know that using audio in a guest Remote Desktop Server is not a good idea, but a limited use of audio is a critical requirement for the customer...

Regards

Hello,

I tried to install the ESXi 5.5 on a machine with the following specs

 

+++++

MotherBoard+CPU : ASUS Z97 Deluxe + i7 4790

RAM : GSkill RIP JAWS-X 1600 (8GBx4pcs) CL10

HDD :WD 3.5 SATA BLACK 2TB

Casing : Cooler Master 311

Power Supply : Seasonic S128-Non MODULAR520W

+++++

 

The problem is when I install the ESXi 5.5, it can't detect the HDD.

 

And I also changed the CPU settings as follows.

 

+++++

Intel Adaptive Termal Monitor Enable
Hyper-Treading Enable
Actie Processor Cores All
Limit CPUID Maximum Disable
Execute Disable Bit Enable
Intel Virtualization Technology Enable
Hardware Perfetcher Enable
Adjacent Cache Line Prefetch Enable
Boot Performance mode Turbo Performance

+++++


But, still can't detect the HDD
So, I tried to install to usb.

After installing the ESXi to the usb, the system still can't detect the Datastore.

So, is there any idea or any suggestion?


I also attached the screenshot.
