In my lab, I am in the process of moving off of Vmware/ESXi and onto RHEV (Red Hat Enterprise Virtualization). So far the learning curve has not been that bad.... Installing and configuring RHEV-M was just as simple as installing a few packages on top of RHEL 6. I had an unused desktop that was more than up for the task. For RHEV-H... Well I had just finished building out a server for it. Once my initial hardware was up and running it was time to start moving virtual machines out of Vsphere.

ESX 5: How to Power On A Virtual Machine from the Command Line
So lately I have been noticing some strange issues with my home lab. Every so often I find my all my virtuall machines are down, however the ESX box is up and running fine.

For this reason it is imperative that you setup a remote syslog server and … Continue reading Configuring Remote Syslog in ESXi 4.1 via the Linux RCLI
Raising A Virtual Machine From the Dead, or How I Screwed Up a VM and Resurected It
Something really nasty happened to me when I was working on storage vmotioning a ton of VMs onto new datastores. Basically I was not paying attention and tried to manually remove a Virtual Machine from the datastore using the datastore browser. This basically wiped out the .vmx and.vmdk files, leaving only the flat.vmdk file which … Continue reading Raising A Virtual Machine From the Dead, or How I Screwed Up a VM and Resurected It

Other HA Configuration Error in ESXi and ESX cluster
Ran into the error below yesterday after rebuilding an ESX 4.0 host as ESXi 4.1 and attempting to enable HA after the newly rebuild ESXi host was added back to the cluster.
Cannot complete the configuration of the HA agent on the host. Other HA configuration error.
Since error message was dissapointingly unspecific, I called VMware Support and asked for their guidance. According to my tech, they are actually getting a lot of calls on this error, as may who are doing in place upgrades to esxi from esx are running into this.
