When the Xen guest asks to unplug *emulated* NICs, it's kind of unhelpful
also to unplug the peer of the *Xen* PV NIC.

In net_cleanup() we only need to delete the netdevs, as those may have
state which outlives Qemu when it exits, and thus may actually need to
be cleaned up on exit.
The nics, on the other hand, are owned by the device which created them.
Most devices don't bother to clean

When fire_watch_cb() found the response buffer empty, it would call

This will instantiate any NICs which live on a given bus type. Each bus
is allowed *one* substitution (for PCI it's virtio → virtio-net-pci, for
Xen it's xen → xen-net-device; no point in overengineering it unless we
actually want more).

The primary Xen console is special. The guest's side is set up for it by

This will instantiate any NICs which live on a given bus type. Each bus
is allowed *one* substitution (for PCI it's virtio → virtio-net-pci, for
Xen it's xen → xen-net-device; no point in overengineering it unless we
actually want more).

I can't see how this has ever worked. If I start with the simple attempt
"-nic user,model=xen", it creates a device with index -1 because it's
assuming that it'll be attached to a hubport. So it creates a frontend

If xen_backend_device_create() fails to instantiate a device, the XenBus
code will just keep trying over and over again each time the bus is
re-enumerated, as long as the backend appears online and in
XenbusStateInitialising.

This is kind of redundant since without being able to get these through
some other method (HVMOP_get_param) the guest wouldn't be able to access

The primary console is special because the toolstack maps a page at a

A previous implementation of this stuff used a 64-bit field for all of
the port information (vcpu/type/type_val) and did atomic exchanges on

just kept it simple with locking instead.

The per-vCPU upcall vector support had two problems. Firstly it was
using the wrong hypercall argument and would always return -EFAULT.
And secondly it was using the wrong ioctl() to pass the vector to
the kernel and thus the *kernel* would always return -EINVAL.

In net_cleanup() we only need to delete the netdevs, as those may have
