Всем привет! На виртуалке крутится CentOS 8. В один прекрасный момент перестало работать сетевое подключение:

Используется dhcp, вот конфиг из network-scripts:

PROXY_METHOD=none
BROWSER_ONLY=no

# ip -br addr
lo UNKNOWN 127.0.0.1/8 ::1/128
enp0s8 UP
virbr0 DOWN 192.168.122.1/24
virbr0-nic DOWN
Смущает какой-то вот этот адаптер virbr0 (судя по названию, virtual bridge или что-то такое) и что у него адрес начинается на 192.168.122, а у меня локальная сеть 192.168.1.*
# ping 192.168.1.1
connect: Сеть недоступна
Что-то не могу понять, куда вообще копать. Пробовал в VirtualBox вырубать один сетевой адаптер и включать другой - не помогло. И вообще непонятно, что и из-за чего поломалось.
