Eric Siebert over at vsphere-land has opened the 2013 voting for the top virtualization blogs. I am hoping to make it into the top 50 this year.

Things always come up in life but the good bloggers keep going regardless of what is happening in their […]

Cannot update the dynamic configuration policy error vCenter Appliance

By admin on February 15, 2013 in General

Working in my lab today, I was having some issues with deploying virtual machines within vCloud Director. I remember a while ago that Chris Colotti had written an article about the importance of NTP with vCloud Director. I thought I had better syncronize the vCNSM (formally vShield Manager), vCenter Appliance, and vCloud Director. Setting NTP on a vCD cell and vCNS Manager is a very simple task, but how do you do it on the vCenter Appliance? There is no option through the configuration UI. A quick google showed me this page within the vSphere 5.1 documentation center. Procedure Log into the vCenter Server Appliance as root. From a command line, enter the following commands to configure and start an NTP client. yast2 ntp-client add server=your_chosen_time_server yast2 ntp-client enable Enter the following command to request immediate synchronization with the time server. sntp -P no -r your_chosen_time_server However following this guide, […]

Some vCloud Networking and Security Q&A’s

By admin on February 5, 2013 in vCloud Networking and Security

Q. When I configure vCNS Edge HA, what is the “Management IP” referring to? A. HA Management IP is the IP Address used for communication between the active and standby Edge. By default, the user does not need to worry about it (we call it zero-configuration), but the user has the option to explicitly specify it (and its interface). As you know, the IP Address is shared between the active and standby Edge, except this HA Management IP, which should be different. Q. If I enable HA, will it reboot the current Edge device during the installation of the new HA Edge device? A. No. When a user enables HA, vCNS Manager will deploy the secondary Edge device and republish the new configuration to both Edge devices. No reboot of the original Edge is required. In most cases, the original Edge device will be the initial active device, so there […]

My top 10 vCloud People to follow

By admin on February 1, 2013 in Cloud Computing

So with all the new posts flying around on the top 10 people to follow for Virtualization, for Storage and Cloud amongst others, I thought I would write my own Top 10 vCloud people to follow. This is purely based on my opinion and I am not going to rank these, it is just people I follow everyday to help with my daily work. Kendrick Coleman – @kendrickcoleman – I’m Kenny Coleman (Kendrick is my full name), and live in Louisville, KY. I started my career off as a windows system engineer after graduating from the University of Kentucky, which lead me wanting to get back into networking and landed me my first certification, CCNA. As a Cisco and systems engineer, it lead me into my new passion of virtualization. I’ve been honored by VMware with the vExpert award for my contributions to the VMware community and being a virtualization evangelist. […]
