v0.15.1
Cold-start code execution is ~4s faster when network is not requested.
| Before | After | |
|---|---|---|
| Host overhead (no network) | ~4,200ms | ~10ms |
| Host overhead (with network) | ~15ms | ~15ms |
QEMU's virt (ARM64) and pc/q35 (x86 fallback) machine types create a default NIC even when no network is needed. The guest-agent detects it and spends ~4s verifying gvproxy connectivity before giving up. Fix: pass -nic none to suppress the default NIC.
