Thank you for the bug Asaf and making cloud-init better.


 It seems like your nocloud network-config YAML file exposed to your vm in the file 
"Read 120 bytes from /run/cloud-init/tmp/tmpb_430skf//network-config"
... represents the mac_address value as an integer.

2020-06-10 06:56:30,126 - stages.py[DEBUG]: applying net config names
for {'version': 1, 'config': [{'type': 'physical', 'name': 'eth0',
'mac_address': 41120542311, 'subnets': [{'type': 'dhcp'}]}]}


https://cloudinit.readthedocs.io/en/latest/topics/network-config-
format-v1.html

cloud-init suggests in network config docs above that mac_address values
should be colon-delimited values such as 04:11:20:54:23:11. Also, the
network-config file is read as yaml, any integer-only values present in
yaml will be interpreted as an int instead of strings. To ensure yaml
sees an integer value as a string you would need either single quotes or
double quotes around a value.


Since this network-config does not conform to cloud-init's documeted
network config v1 for mac_address, I don't believe we will be addressing
this feature request upstream as most tooling generally sees and
represents mac addresses as colon-delimited values for readability
instead of a squashed string of 12 hex-digits.

Again thanks for the report, please feel free to reopen if we are
missing a significant use-case here that should be better handled.
