Subject: [PATCH 0/7] Add vmnet.framework based network backend
Date: Thu, 17 Jun 2021 17:32:39 +0300 [thread overview]
Message-ID: <20210617143246.55336-1-yaroshchuk2000@gmail.com> (raw)
macOS provides networking API for VMs called vmnet.framework.
I tried to add it as a network backend. All three modes are supported:
-shared:
allows the guest to comminicate with other guests in shared mode and
also with external network (Internet) via NAT
-host:
allows the guest to communicate with other guests in host mode
-bridged:
bridges the guest with a physical network interface
Separate netdev for each vmnet mode was created because they use quite
different settings, especially since macOS 11.0 when vmnet.framework
gets a lot of updates.
Not sure that I use qemu_mutex_lock_iothread() and
qemu_mutex_unlock_iothread() in correct way while sending packet
from vmnet interface to QEMU. I'll be happy to receive
recomendations how to make this thing better if I done sth wrong.
Also vmnet.framework requires com.apple.vm.networking entitlement to
run without root priveledges. Ad-hoc signing does not fit there,
so I didn't touch anything related to signing. As a result we should
run qemu-system by a priviledged user:
`$ sudo qemu-system-x86_64 -nic vmnet-shared`
otherwise vmnet fails with 'general failure'.
But in any way it seems working now,
I tested it within qemu-system-x86-64 on macOS 10.15.7 host, with nic
models:
- e1000-82545em
- virtio-net-pci
and having such guests:
- macOS 10.15.7
- Ubuntu Bionic (server cloudimg)
