Из под Ubuntu 16.04 x86_64 запускаю qemu-system-arm. Насколько я понимаю, он же должен по дефолту создавать виртуальный интерфейс аналогичный поднятому на хосте eth0 ?
Под убунтой есть гигабитная сетёвка, точно рабочая:

В документации написано:
By default QEMU will create a SLiRP user network backend and an appropriate virtual network device for the guest (eg an E1000 PCI card for most x86 PC guests), as if you had typed -net nic -net user on your command line
Я так и не понял - я должен ему указать, что у меня девайс не е1000, а atl1e , или какого рожна ему надо.
Если кто может указать что не так - буду очень благодарен.
