Hi,
I have an issue that i have spent several hours on an i can not get it resolved.
OS: ubuntu 18.04
I am unable to get virtual machines to get an assigned IP address, i am running KVM.
What i try to archive is pretty straight forward, spin up a debian 9 image in a VM with an IP address that i can SSH to from within my local network.
/etc/libvirt/qemu/networks/br0.xml
/etc/netplan/01-netcfg.yaml
newbee@server:/etc/netplan$ sudo netplan --debug apply
newbee@server:/etc/netplan$ sudo networkctl status -a
newbee@server:/etc/netplan$ ifconfig
newbee@server:/etc/netplan$ virsh net-list
newbee@server:/etc/netplan$ virsh net-dhcp-leases br0
newbee@server:/etc/netplan$ virsh net-dhcp-leases default
root@hassio:~# ip address show (manual typed, since i can only connect to host via virtual machine manager / remote desktop)
I assume the problem is related to the host and not the guest, but i am unable to figure out what to do. Anyone have an idea?
my guess is that the problem is related to the netplan configuration.
Many thanks
