Public bug reported:
In the past week, I upgraded three machines using do-release-upgrade from
Ubuntu server 22 to 24.
All had static IPs configured:
#1 with /etc/network/interfaces (oldschool!) (hostname=ocelot)
#2 /etc/netplan/00-installer-config.yaml (as originally created by subiquity)
(hostname=toolbox)
#3 /etc/netplan/90-config.yaml (hostname=couch)
All were simple (physical) configurations: just one ethernet interface, one
network. (plus docker in #2-3, plus some ppp's in #3). #3 also had multiple IPs
bound to eth0 (to enable routing by source ip addr)
#1-2 are running as a vm under the same xen hypervisor (ubuntu 22.04.3), #3
runs bare-metal (dell xeon)
In cases #1-2, the config file was NOT updated from 'eth0' to 'enX0' and the
machine did not come back on the network. Luckily, I had access to the console,
or I'd be screwed.
In case #3, 'eth0' is still the configured interface.
So... I guess it's xen related, then? Note the hypervisor (host os) did
not change, only the guest vm was upgraded from 22 to 24.
#1 hvm
```
$ cat ocelot.hvm
builder = "hvm"
name = "ocelot-hvm"
memory = "1024"
vcpus = 1
vif = ['']
#disk =
['phy:/dev/lvg/ocelot-root,hda,w','file:/root/dmg/ubuntu-16.04.3-server-amd64.iso,hdc:cdrom,r']
# lol, long upgrade history here!
disk = ['phy:/dev/lvg/ocelot-root,hda,w']
vnc = 1
boot="dc"
```
#2 hvm
```
$ cat toolbox.hvm
builder = "hvm"
name = "toolbox-hvm"
memory = "3072"
vcpus = 1
vif = ['']
#disk =
['phy:/dev/lvg/toolbox-root,hda,w','file:/root/dmg/ubuntu-20.04.4-live-server-amd64.iso,hdc:cdrom,r']
disk = ['phy:/dev/lvg/toolbox-root,hda,w']
vnc = 1
boot="dc"
```
