Creating a new Worker

Serial Number Generation (Licence)

Execute the following commande to get the machine's uuid

The machine's uuid looks similar to abc1de2-fg3hi4jkl-mn5opq-rs6tuvw78xy9z10

sudo dmidecode -s system-uuid

If instead of machine's uuid you got the message Not Settable execute the following command

cat /etc/machine-id | sed 's/\(......\)\(....\)\(....\)\(....\)/\1-\2-\3-\4-/'

Copy the machine's uuid to the KhaCloud dashboard's Serial Generator

The generated Serial Number will look similar to PrSer2r10Pr07U7soAceQserFIrM6iPk8PSerlxtbPrSeHvqprserizo5IuPr5GlCESngyprserDEOjZFXOB

Then go the KhaCloud's servers section and insert the serial number to the new created server
