Hi,
I'm trying out passt with custom QEMU (we emulate a proprietary device).
On one terminal I'm running latest passt (3eb26fe):
./passt --debug -f -t 55556:22 -s /tmp/passt.socket
On another terminal I'm running our qemu-system-x86_64 with:
-device virtio-net-pci,netdev=net0 -netdev
stream,id=net0,server=off,addr.type=unix,addr.path=/tmp/passt.socket
QEMU starts and the VM boots, but without network:
[FAILED] Failed to start NetworkMan...[0m - Network Manager Wait Online.
On passt side I see this log:
No external routable interface for IPv6
Outbound interface (IPv4): ens160
MAC:

Looks like a handshake timeout.
Am I doing something wrong?
Thanks,
