Eating my own dog food – Blog Migration

By admin on January 30, 2012 in General

I have now successfully migrated my blog site to a vCloud hosting provider, essentially Eating my own dog food. Practicing what I preach. Virtacore are providing the hosting through there vCloud Express Public Cloud offering. They provide there own portal to interface with vCloud Director and I must say it is quite impressive. The great side to now using a vCloud Express provider is that I now fully manage my own blog, from VM to OS to WordPress. This is great. If there is now an outage for maintenance I can only blame myself. For anyone who watched the Brownbag I did with Chris Colotti, you will probably be laughing at that statement. How did I do the migration? I downloaded a Turnkey Linux WordPress appliance. I then customised this appliance, ensuring VMTools were up to date, creating plenty of disk space for my images etc. Once this was all […]

By admin on January 24, 2012 in Cloud Computing

I got a question earlier about how to find out which database server vCloud Director is using. To do this follow the steps below: Connect to the vCD cell using SSH Navigate to /opt/vmware/vcloud-director/etc cat global.properties You will see an output similar as this: # Database connection settings database.jdbcUrl = jdbc:jtds:sqlserver://192.168.10.163:1433/vcd;socketTimeout=90;instance=SQLExpress database.username = vcd database.password = dSLuRFq1fqHaADwT298j5aTy1GUfJxualYQSZv2Oa2xjR4b869x47Ihp1XAZj4cB The IP address highlighted in bold is the IP address or FQDN of the configured database server

By admin on January 13, 2012 in General

This question is asked a lot. How do I enable lock down mode and what does it do. To enable lock down mode, there are two options. From the DCUI (Direct Console User Interface) From within vCenter My preffered option is through vCenter, it is very easy and you dont need to be in front of the host or have remote console access. To enable lock down mode through vCenter follow these steps: Login to vCenter Select the host Select the configuration tab Select Security Profile under software Scroll down to Lockdown mode Click Edit Tick Enable Lockdown Mode Click OK Lockdown mode is now enabled Please Note: Enabling Lockdown mode on an ESXi 5 host will force all users to login via the vCenter Server in order to manage their ESXi hosts. The table below shows what features are enabled and disabled with Lockdown mode (this was taken from Yellow-bricks) […]

Changing the IP address of a vCloud Director cell

By admin on January 12, 2012 in Cloud Computing

Working on a solution with Chris Colotti and other colleagues, we came across a KB article that details how to change the IP address on a vCD cell. I had never thought about this previously, having never changed an IP address of a cell. When you build your vCD cells, you bind specific services to IP addresses. You need to make the database aware of these changes once you have re-ip’d the operating system. This KB Article explains the full procedure on how to do this. These are the steps how to reconfigure the vCD database from the KB article above: o change the IP address of an installed vCloud Director server: Ensure to shutdown all the cells.To shutdown a cell, run this command from within the Red Hat system which is hosting the vCloud Director software:service vmware-vcd stop Change the column value of PRIMARY_IP in the CELLS table to the […]
