Hi All Xen experts,
I hope I can start using Xen with Ubuntu since Xen Centos community does not really exist anymore.
I have been running it for almost 20 years now and have relatively old VMs I would like to run as is IF possible.
I got started with this link:
https://help.ubuntu.com/community/Xen
I am trying to setup the bridge BUT as of late Ubuntu all network configuration files are made with the infamous YAML syntax (equate nightmare and hours lost).
The above document is for the old syntax and assume DHCP, which we will not be using.
An additional pain seems to be that somehow the eth0 now is named eno1: I assume it is a o and not a zero AND it is a 1 not a lower case L, see already how helping this adds to the YAML issues!
eno1: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
inet 142.44.136.79 netmask 255.255.255.0 broadcast 142.44.136.255
inet6 fe80::a6bf:1ff:fe1e:8de2 prefixlen 64 scopeid 0x20<link>
ether a4:bf:01:1e:8d:e2 txqueuelen 1000 (Ethernet)
RX packets 802076 bytes 1115505036 (1.1 GB)
RX errors 0 dropped 0 overruns 0 frame 0
TX packets 120995 bytes 15878802 (15.8 MB)
TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0
device memory 0xa0b00000-a0bfffff
Now after re enabling the old network management with ifdown I get all kind of error messages:
ifdown: interface enol not configured
ifup: missing required variable: address
ifup: missing required configuration variables for interface xenbr0/inet
ifup: failed to bring up xenbr0
It seems pretty basic stuff to me BUT with all these new changes to syntax to Ubuntu and the old documentation I wonder if anyone found a way to configure the bridge either with the old syntax of the new one?
Any help will be appreciated.
Best Regards,
Steven,
