Updating VMware ESXi

Back in January I built a VMware ESXi 5 whitebox as my home server.  I updated the hypervisor today and I thought I’d record the process so that I can refer back to it later.  The blog post I found most useful was from VMware Front Experience.  If you’re looking for the detailed procedures, I’d suggest you look at that post.

Upgrading from 5.0 to 5.1

  1. The upgrade file can be found here on the VMware download site. For an upgrade from 5.0 to 5.1, the file to download is: VMware-ESXi-5.1.0-799733-depot.zip.
  2. After downloading the file, scp it to the ESXi host, onto one of the data stores.
  3. SSH into the ESXi host, and run the command:
    esxcli software profile install -d /vmfs/volumes/datastore1/VMware-ESXi-5.1.0-799733-depot.zip -p ESXi-5.1.0-799733-standard
    You can also run esxcli software profile update .... The difference is described in the blog post I referenced above.
  4. When the update completes, reboot the server. When you bring up the VMs again the first time, vSphere Client might ask you whether you moved or copied the VMs since the UUID changed. Select “I moved the VMs”.

Rolling back to ESXi 5.0

ESXi 5.1 wasn’t working too well for me. I was having problems passing through my USB controllers to the VMs. I decided to roll back to 5.0, and luckily VMware makes rolling back easy.

  1. When you reboot the host, press SHIFT+R when the hypervisor first boots up (you’ll see the cue at the bottom right of the screen
  2. Type ‘y’ to confirm rolling back the hypervisor
  3. The hypervisor will boot up with the old version.

Patching 5.0

So what I ended up doing was just patching the hypervisor to the latest build.

  1. The latest patches can be found on the VMware patch download portal.
  2. After downloading the file, scp it to the ESXi host, onto one of the data stores.
  3. SSH into the ESXi host, and run the command:
  4. esxcli software vib install -d "/vmfs/volumes/datastore1/patches/ESXi500-201209001.zip"
  5. When the update completes, reboot the host if required.
