Creating a subnet

I am trying to create a subnet like so

curl -X POST --data '{
    "jsonrpc": "2.0",
    "method": "platform.createSubnet",
    "params": {
        "controlKeys":[
            "P-fuji17m6372t6mj7u7c7s5cdg4z9zjpmpleqvxk53z2",
            "P-fuji1d2egfvyxu3vvn64lxqt9czvcv9klsqj6xdwy5r"
        ],
        "threshold":2,
        "username":"usernam",
        "password":"password"
    },
    "id": 1
}' -H 'content-type:application/json;' 127.0.0.1:9650/ext/P

I get the following in response

{“jsonrpc”:“2.0”,“error”:{“code”:-32000,“message”:“couldn’t create tx: couldn’t generate tx inputs/outputs: provided keys have balance (unlocked, locked) (0, 0) but need (10000000, 0)”,“data”:null},“id”:1}

Does it mean i dont have enough balance, which accounts should have balance ? These?
“P-fuji17m6372t6mj7u7c7s5cdg4z9zjpmpleqvxk53z2”,
“P-fuji1d2egfvyxu3vvn64lxqt9czvcv9klsqj6xdwy5r”
How do I transfer AVAX to these accounts?
