I have the following setup:
Debian buster OS with KDE desktop
AMD-64 4 cpu processor
Host Debian Buster
Guest kubuntu 18.04
Virtual Machine QEMU
I followed the wiki instructions to set up a bridge between the two
operating systems but can't get it to work. Not only does the guest
networking not work but my setup kills the host's as well. My
/etc/network/interfaces file is:
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).
source /etc/network/interfaces.d/*
*______________________________________________*
# The loopback network interface
auto lo
iface lo inet loopback
#auto enp4s0
iface enp4s0 inet manual
auto br0
iface br0 inet dhcp
pre-up ip tuntap add dev tap0 mode tap user ctech
pre-up ip link set tap0 up
bridge_ports all tap0
bridge_stp off
bridge_maxwait 0
bridge_fd 0
post-down ip link set tap0 down
post-down ip tuntap del dev tap0 mode tap
*____________________________________________*
The host name is ctech.
I have reset the network, using /etc/init.d/networking restart, after
each change.
I have looked for more documentation with no success. QEMU doesn't have
a user forum that I can find.
Any help will be sincerely appreciated.
