I am having a HECK of a time getting virtual machines running on 18.04 (server) LTS. I say running, because it FEELS like virsh REPORTS it running, but that it never starts up. This is a very basic test VM I am trying to set up so that I can get the syntax correct for my couple production (home server) VMs I am trying to get stood up. I want to quit and move back to 14.04 LTS like I did years ago, but I am trying to learn WHY I am seeing what I am.
This is a FRESH install of Ubuntu server 18.04 LTS, and only the following has been done thus far.
add to /etc/apt/sources.list, this prevents the packages from not being found and installed by OS, specifically mailutils & ubuntu-vm-builder.
deb http://archive.ubuntu.com/ubuntu/ bionic universe
deb http://archive.ubuntu.com/ubuntu/ bionic-updates universe
sudo apt-get install zfsutils-linux
sudo zpool import Storage
sudo zpool status
sudo apt-get update
sudo apt-get upgrade
sudo apt-get install htop nmon samba nfs-kernel-server nfs-common qemu-kvm postfix mailutils ubuntu-vm-builder libvirt-bin
disable floppy:
echo "blacklist floppy" | sudo tee /etc/modprobe.d/blacklist-floppy.conf
sudo rmmod floppy
sudo update-initramfs -u
Here is the output of /etc/netplan/50-cloud-init.yaml: (I don't know about this one, I do NOT have the cloud instance installed, so perhaps there is a problem with the actual installation of 18.04 LTS, because all accounts I have seen on this indicate this APPEARS to be a different version installed than what I am expecting.
network:
version: 2
renderer: networkd
ethernets:
switchports:
# all cards on second PCI bus; unconfigured by themselves, will be added
# to br0 below
match:
name: enp1*
mtu: 4400
bridges:
# the key name is the name for virtual (created) interfaces; no match: and
# set-name: allowed
br0:
# IDs of the components; switchports expands into multiple interfaces
interfaces: [switchports]
addresses: [172.16.5.20/24]
gateway4: 172.16.5.1
nameservers:
addresses: [172.16.5.2]
parameters:
forward-delay: 0
stp: false
sudo netplan apply
As you can see, bridge 0 is up and good, able to reach internet, able to ssh to host without issue.
br0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
inet 172.16.5.20 netmask 255.255.255.0 broadcast 172.16.5.255
Below is the output of the command used to spin up the VM. I am a little confused at the errors seen, as they show as informational, and don't stop the setup. When trying to ping, I only get "dest host unreachable".
