Problem

When trying to Power On an old VM I was greeted with this message:

I checked the Datastore and everything seemed to be present and correct. I tried to migrate the VM to a different Host, but again I was shown this error. A quick Google didn't show up anything useful so I decided to check the logs.

running the command  tail /var/log/vmware/hostd.log -f whist trying to Power On the VM flagged these error messages:

Using ESXTOP With VMware ESXi

Just a quick post about using ESXTOP with VMware ESXi. Obviously in ESXi there is no Service Console so we have to use the vMA (vSphere Management Assistant) to help us. If you haven't installed the vMA on your infrastructure yet, you can download it here: http://www.vmware.com/support/developer/vima/

Once install and configured, login and run the following command: resxtop –server <server name>

You will be prompted to login, use the root user/pass of the Host you want to run ESXTOP on (Note: Logging in as root will not work if the Host is in "Lockdown Mode".). You should then be presented with ESXTOP, I believe it has all of the same function as it did in the Service Console

Here you can see all avaliable options when connecting to a Host using RESXTOP

usage: resxtop [-h] [-v] [-b] [-s] [-a] [-c config file] [-d delay] [-n iterations]
               [--server server-name [--vihost host-name]] [--portnumber socket-port] [--username user-name]
              -h prints this help menu.
              -v prints version.
              -b enables batch mode.
              -s enables secure mode.
              -a show all statistics.
              -c sets the esxtop configuration file, which by default is .esxtop4rc
              -d sets the delay between updates in seconds.
              -n runs resxtop for only n iterations.
              --server      remote server name.
              --vihost      esx host name, if --server specifies vc server.
              --portnumber  socket port, default is 443.
              --username    user name on the remote server.
       for more information on interactive and batch modes
       please see man page for resxtop.

	

PowerCLI: Reconfiguring NTP Servers on ESX Hosts

Just lately I’ve been creating a lot of PowerCLI scripts to help configure various aspects of out ESX environment. We’ve just implemented a new NTP Server to our network. So I was given the job to update all of our ESX Hosts. I didn’t fancy spending all morning manually changing them, so I set to work in creating a PowerCLI script to do the business. Here is the result.

$Cluster = "<cluster name>" 
$Hosts = Get-Cluster $Cluster | Get-VMHost 
ForEach ($Host in $Hosts) 
{ 
Remove-VmHostNtpServer -NtpServer "<old ntp server>" -VMHost $Host | Out-Null  
Add-VmHostNtpServer -NtpServer "<new ntp server>" -VMHost $Host | Out-Null 
Get-VmHostService -VMHost $Host | Where-Object {$_.key -eq "ntpd"} | Restart-VMHostService -Confirm:$false | Out-Null 
write "NTP Server was changed on $Host" 
}

Is It A Bird? Is It A Plane? No, It’s….The Cloud!

 

Cloud

Why, oh why, oh why, has every man and his dog started calling everything Cloud? Cloud Hosting, Cloud Apps, Cloud Services? Is it me, or was it only 6 months ago that these were called Virtual Hosting, Web Apps, Web Services? What's changed? In my eyes, nothing! I hadn't really noticed this until the other day when I was attending a "Cloud" seminar.

Cloud Hosting: What makes it Cloud? It's just Hosting on a Virtualization platform. Cloud Apps: Why are they Cloud Apps? They are just applications hosted over the Web, no? If we follow this trend we'll soon be calling WebMail, CloudMail!

A Simple VMware ESXi Rapid Deployment System – Part 3 of 3

 

Introduction and Requirements– Part 1
Testing and Exporting to vSphere – Part 2

Customising the ESXi Rapid Deployment Server

I couldn't just stop there could I? I decided to make a few alterations to make it a little prettier and hopefully quicker.

Removing some ESXi installation steps which are not required

I'll start off by talking about making some changes to the ESXi installation to help make the deployment a little quicker. I got the idea from Stuart Radnidge's great post; Unattended ESXi Installation. Stu talks about editing one of the Python files that make-up the ESXi installation. Stu has a link to a pre-prepared Install.tgz for you to replace the default Install.tgz that comes in the ESXi ISO. Unfortunately this wouldn't work for me as I was using the ESXi ISO that comes with HP Management Agents so I had to make the changes myself:
