I'm working on debian stretch with the newest xen from repositories. I've never worked with xen before, so bare with me. I've searched far and wide, and all solutions I apply do not work.
Installing xen-system and xen-tools gave no errors, though when I try to start a guest (we'll call it dom1) it won't work unless I create a bridge. I create a bridge with brctl and call it xenbr0, and link it to the main interface (it's called eno1 on my server).
Starting dom1 now works, but there is no connection to any network, not even the LAN, neither from host nor guest. No response from the server either, if I try to ping it from a different device.
/etc/network/interfaces (after having followed the latest guide I could find):
auto lo iface lo inet loopback #xen auto xenbr0 iface xenbr0 inet static address 192.168.0.201 netmask 255.255.255.0 network 192.168.0.0 broadcast 192.168.0.255 gateway 192.168.0.1 dns-nameservers 192.168.0.1 188.8.131.52 184.108.40.206 dns-search google.com #The primary network interface auto eno1 iface eno1 inet manual
I don't know what I haven't tried. I've edited /etc/xen-tools/xen-tools.conf, /etc/xen/xl.conf, resolv.conf, and /etc/network/interfaces all according to every guide I could find (of course having gone back to the default configurations at first).
Anything you guys can help me with? Thanks in advance!
EDIT I edited /etc/network/interfaces to:
allow-hotplug eno1 iface eno1 inet static bridge_ports xenbr0 address 192.168.0.201 netmask 255.255.255.0 network 192.168.0.0 broadcast 192.168.0.255 gateway 192.168.0.1
Now, when I DON'T create a bridge, I can connect to the internet. Once I create a bridge, the same problem occurs: neither host nor guest can connect to any network, and neither can a device on the network ping the host or guest.
