Virtualization

Can't edit virtual machines once you upgrade to VMware 5.5 ESX and a virtual machine version 10

If you recently upgraded to VMware 5.5 you will notice this warning if you try to edit your virtual machines.

error

“You cannot use the vSphere Client to edit the settings of virtual machines of version 10 or higher.  Use the vSphere Web Client to edit the settings of this virtual machine.”
Unfortunately the vSphere Web Client is not free.  So while you could download this you would be running in trial mode.  The simplest fix for this issues is to follow the following steps.

  1. Power down your VM.
  2. Right click on your VM and “remove from inventory”.
  3. Browse to the datastore and download the VMX file associated with the machine.
  4. Open notepad and edit the VMX file.  Look for virtualHW.version = “10″
  5. Edit the 10 and simply change it to a 9.  Save the file
  6. Upload it back to your VMware server.
  7. Browse to your datastore and click on “Add VM to inventory”.
  8. Power your system back on.

Vmware server 503 Service Unavailable Fix

Recently I installed Vmware Server. When I opened the web browser it popped up with an error service unavailable 503. To fix follow the steps below.

First find your tomcat directory. In my instance the directory was C:Program Files (x86)VMwareVMware Servertomcat
Open the /bin folder

Now you need to right click on tomcat6.exe and go to properties. Click on the compatibility tab

Click on the button that says change settings for all users.

You will now see a new window with a single tab labeled compatibility for all users
Check the box that says “Run this program in compatibility mode for:”

That is it now you can start your Vmware service and open your browser.

Virtual machine seems everything takes 100% processor

There is a problem that exists where if you assign too much of the physical memory to a VM it will seem like every process you start bogs down the processor.  Anything from word to SQL server.  If you experience this problem try decreasing the ram to half of what you have and see if that makes a difference.

Moving a virtual machine from one datastore to another

First thing you need to do obviously is make sure ESX can see both of your datastores.

Power off the virtual machine that you wish to copy.

SSH into the server using putty or like product.

go to /vmfs/volumes and go into the volume in which you want to move your data:

cd /vmfs/volumes/Datastore2

mkdir <Name of VM directory>

cd /

Now switch back to source datastore

cd /vmfs/volumes/Datastore1

cp *.* /vmfs/volumes/Datastore2/<Name of newly created VM directory>

Depending on the size of your datastore this obviously can take a very long time.

Now you have to register the new virtual machine

Go into virtual infrastructure, Click on the left the name of your ESX server, Go to the configuration tab.

From here go down to storage on the right hand column, double click the datastore in which you moved the VM. 

Browse until you get to the folder that you moved.  Find the vmx file right click on it and select add to inventory. 

Congratulations you are finished.

Installing Trixbox(Asterisk) on an ESXi server

Install stage:

1. Download the Trixbox ISO. This will probably take ~1 hour.
2. Create a new virtual machine in ESXi with the following options

  • Typical
  • Linux other 32-bit
  • 1024 for memory
  • 10gb disk
  • 3. Follow this blog to mount the ISO as a virtual Cd-rom. http://www.n2networksolutions.com/blog/?p=366
    4. Power on the virtual machine

  • Push at the main screen
  • I’m getting an error saying
  • The Trixbox CD was not found in any of your CDROM drives. Please insert the Trixbox CD and press OK to retry.

  • I’m going to try re-uploading the ISO to my ESXi server.
  • This did not work

  • Going to try and re-download the ISO then re-upload it to ESXi
  • Well I could not get this problem resolved so I’m just going to download the Trixbox Vmware appliance. It is 2.6.1 as opposed to 2.6.2 but you can always upgrade after the install. Here is the link.

    1. Ok the first step here I’m going to use vCenter converter to import this virtual appliance into my ESXi server.
    2. Converting is very simple once the program is installed click on the “Convert Machine” button which will bring up this window.
    1
    3. What you want to do is browse to the file we downloaded in the previous step after it is unzipped. trixbox 2.6.1-vmware.vmx
    4. Once you click next it will ask you to supply your login to your ESXi server.
    5. The next step allows you to rename your VM to whatever you want and select your data store.
    6. The next step allows you to change your hardware settings for the virtual machine. I’m going to change two settings here:

    Change to a 10gb disk

  • Change the memory from 512 to 1024
  • 7. Once you click next you are ready to start your conversion. Now keep one thing in mind. This converter has to upload the large file we downloaded to the server. So if you are on a time crunch and are on wireless make sure you hardwire and disable your wireless. This will ensure you save the most time.

    Configuration phase:

    1. Ok now that we have the virtual machine install make sure it is powered on. It uses DHCP so you need to figure out what IP address it got. This can be accomplished by logging in to the Trixbox console with username root and password trixbox. Once you get the # type in ifconfig. This will display the IP.
    2. This is going to be a server so we will want to configure a static IP or else it will be getting using DHCP which could cause all types of problems down the road.

  • vi /etc/sysconfig/network-scripts/ifcfg-eth0
  • DEVICE=eth0
    ONBOOT=yes
    BOOTPROTO=none
    BROADCAST=192.168.2.255
    IPADDR=192.168.2.3
    NETMASK=255.255.255.0
    NETWORK=192.168.2.0
    now press esc and :wq to save changes and quit

  • vi /etc/resolv.conf
  • nameserver 68.2.16.30
    nameserver 68.2.16.25
    now press and :wq to save changes and quit

    The next step I recommend is opening your Trixbox server from a web browser:
    http://192.168.2.5/maint
    Click on the packages link at the top so we can update our software to the latest version. When I clicked on mine i received the following error:
    Error: The xml response that was returned from the server is invalid. Received:
    alert

    To fix it I was able to type the following from the command line:
    vi /etc/service.php
    From here find the section below and change
    max_execution_time = 300
    memory_limit = 256
    This may not work for you but it did resolve my problem.
    commands

    Once you changed this type the following to restart the http daemon:
    service httpd restart

    Now I am able to successfully open:
    http://192.168.2.5/maint/index.php?packages

    From here I’m going to go down and check every box in the “upgrade” column this way all of my software installed on the server is up to date.

    While trying to install a couple of the updates I’m receiving the following error:
    Error: Missing Dependency: libtds.so.5 is needed by package asterisk

    To fix it:
    yum install libtds.so.5

    Ok now that everything is downloaded and installed I’m going to configure some SIP trunks. I personally use Broadvoice for terminating my voice lines. However, there are tons of service providers out there. Here are my steps.

    Open internet browser to http:///admin
    First thing I’m going to do is edit the trunks
    480+NXXXXXX
    9|1480NXXXXXX
    9|1602NXXXXXX
    9|1623NXXXXXX
    602NXXXXXX
    480NXXXXXX
    623NXXXXXX
    1480NXXXXXX
    1602NXXXXXX
    1623NXXXXXX
    1NXXNXXXXXX

    01146.
    01147.
    01149.
    01152.
    01.

    For trunk name you can put whatever you want

    username=<em>
    </em>
    user=phone
    type=peer
    secret=<em>

    dtmfmode=inband
    dtmf=inband
    context=from-pstn
    canreinvite=no
    authname=<em>
    </em>

    For user context I’m using the following sip.broadvoice.com
    For user details I’m using:
    username=<em>

    Mounting ISO images to ESXi

    If you are trying to mount ISO CD-rom images to ESXi so that you don’t have to physically burn the disc. Here is how.

    1. Download a program called WinSCP. This allows you to use SSH to transfer files.
    2. Open WinSCP to /vmfs/volumes/[name of your data store] then create a directory called ISOS.
    3. Copy the downloaded ISO files from your PC to the ISOS folder.
    4. Open Vmware infrastructure client right click on your server and go to edit settings.
    5. You can either create another virtual CD rom drive or you can mount your ISO to your existing one.
    6. Click on the CD/DVD Drive 1 in your options. On the right hand side select Datastore ISO file. Now simply browse to your ISO and you can mount it as if it were an inserted CD/DVD.

    Finally got ESXi up and running on my Intel i7 based processor system

    So I was finally able to get ESXi up and running. You can see from my previous posts I’ve tried hacking my system I have finally given up after investing probably 30 hours of trying.

    What I finally did was purchase this SAS controller from Amazon:
    SuperMicro Uio Card Lsi 1068E Sas Controller Card

    I also purchased an Intel pro/100 network adapter from Fry’s electronics which appears to be compatible using the e100 driver

    I do have an Intel Pro/1000 pci x1 adapter in the mail. Once it arrives I can hopefully increase my bandwidth to 1GB opposed to the 100MB I’m running currently.

    I’m still debating whether or not I want to convert my home machine into a permanent ESXi server. It would mean I would have to pull one of my old PC’s out of the closet as a workstation….ugh.

    ESXi cannot import an existing Virtual machine with Vcenter converter

    While trying to convert an existing virtual machine with Vcenter Vmware Converter. I received an error that it had failed. So I browsed over to the log file to see what the cause was.

    C:Documents and Settings%username%Local SettingsTempvmware-tempvmware-client-0.log

    After editing the file at the end I see the following:
    [2009-02-20 17:38:49.843 ‘P2V’ 1752 error] [task,295] Task failed: P2VError UNKNOWN_METHOD_FAULT(sysimage.fault.InvalidTargetProductVersion)

    I realized it’s been awhile since I’ve tried to use this utility so I’m going to download the latest version to circumvent this issue.
