# EXOSCALE USERDATA TEMPLATE                                                      PawCloud-XMR
#==========================================================================================================
#
#    Insert this into UserData when you make a new instance.  You should make a template out
#    of this instance, as its your preconfigured 'prime node', using the exo command line.
#    Then make an instance pool out of the template image.  Your nodes should all hook up
#    to your proxy nicely.
#
# Virtual machine settings:
#
#     Hostname:       pawcloud-node
#     OS:             Ubuntu 20.04 LTS
#     Instance Type:  CPU Large 16 vCPU | GB 2 x 2198 MHz
#     Disk:           10 GB
#
# These settings will need to be adjusted after the VM warms up:
#
#     Private Network:       pawcloud (if you don't have one, make one)
#     Private Network Type:  Managed
#     Private Network IP:    10.0.0.2
#
# Please note that warm up time on the prime node can take any where from 30 to 45 minutes
# depending on exoscale's availability for shared cpus at the time you spawn an instance.
# This, in the end is worth the trade off for better hashrate, as xmrig is being built against
# the VMs kernel for the fastest speed/compatibility possible (400h/s -> 2.1kh/s just by
# compiling on a 16 vCPU node for proper AES flags)
