KVM может SSH с хоста не других компьютеров
Я настроил kvm / quemu на сервере. Я следовал за руководством, и оно работало с одним исключением. Я могу только SSH к виртуальной машине через сервер, на котором запущен KVM. Если я использую свой ноутбук, я не могу. Я должен сначала SSH к серверу, а затем VM.
СЕРВЕР Сервер Ubuntu 18.04
Здесь находятся / etc / network / interfaces на сервере.

После того как eno1..я теряю ssh доступ , Я попытался использовать любую строку, кроме eno1 и те же результаты .. пример "bridge_ports mycatisbadass6969". Я предполагаю, что область bridge_ports является виновником. Любые предложения?

Я изменил

<source network='default'/>
</interface>
на
<interface type='bridge'>
<source bridge='br0'/>
</interface>
имеет адаптер lo..ens3 адаптер
Кроме того, я перезагружал сетевые интерфейсы тысячи раз, работая с sudo /etc/inint.d/network restart
Редактировать ... Я обнаружил, что запуск этого ниже позволяет мне использовать адаптер. Все еще не могу ssh напрямую к vm
sudo ip addr flush dev br0
sudo ip addr flush dev eno1
