Regression: since 1.0.0 we can no longer start a VZ instance while offline (no DNS servers configured in /etc/resolv.conf) #3050
Description
While you typically need to be online when creating a new instance (to run apt-get etc. to install fuse or whatever), it is possible to start/stop an instance without an active network connection.
This still works with QEMU, but has been broken for VZ since the 1.0.0 release. Bisecting shows the root cause is the gvisor-tap-vsock upgrade in #2797.
