Public bug reported:
VMs under Boxes no longer have external network access - there seems to
be a private internal network that is functioning fine, but when the
host is connected to a network it is not possible to access this
external network from VMs. Eg. It is possible to resolve DNS names, but
it is not possible to ping external hosts from a VM when the host
connected to the Internet.
This is a regression from zesty.
Looking at virt-manager, qemu:///system has a NAT network defined using
virbr0, but qemu:///session (which Boxes uses) has no network, and it is
not possible to create one - attempting to do so results in a "Operation
not permitted" error:
> Error creating virtual network: error creating bridge interface virbr1:
> Operation not permitted
