ONE_CONTEXT passes ETHx_MTU as a string, but Netplan's network-config-v2 schema requires mtu to be an integer. Without this, cloud-init schema validation fails with "'1500' is not of type 'integer'".

There was a problem hiding this comment.
Thanks for the quick fix there @mcanevet +1 on this correction and changset. I can confirm failures on py 3.14 without this fix.

fix(opennebula): coerce MTU to int in gen_conf()
ONE_CONTEXT passes ETHx_MTU as a string, but Netplan's network-config-v2
schema requires mtu to be an integer. Without this,
cloud-init schema --systemfails with "'1500' is not of type 'integer'".```
Additional Context
Discovered while backporting to cloud-init 25.1.4-1+deb13u1 (trixie).
The fix is a one-liner:
int(mtu)ingen_conf(). The accompanying testexpectation updates (
"1280"→1280) reflect the corrected behaviour.The regression is caught by the schema validation fixture introduced in #6855.
With that PR,
test_gen_conf_mtu,test_eth0_v4v6_override, andtest_multiple_nicsall fail before this fix and pass after.Test Steps
Boot an OpenNebula VM with
ETH0_MTUset in the context, then run:Before this fix, the command fails with:
After this fix, validation passes.
