There is the odd time where you need to reset the 60day trial of ESXi – this guide will explain how
Note this is not for production environments, nor intended to provide an everlasting version of ESXi. Either use the free ESXi version, or licence it for long term.
1. Log into the host via SSH
2. Delete /etc/vmware/license.cfg
rm -r /etc/vmware/license.cfg
3. Copy etc/vmware/.#license.cfg to /etc/vmware/license.cfg
cp /etc/vmware/.#license.cfg /etc/vmware/license.cfg
4. restart VPXA
You should then see in the host web client, the trial is valid for another 60 days. Hopefully this helps out in a pinch.
