I tried to install ubuntu 18.04 container on the centos 7 host
qemu-img create -f raw /data/pools/ubuntu1804.img 50G
make sure download the iso file to /data/images folder ubuntu-18.04.2-server-amd64.iso
virt-install \
--name ubuntu1804 \
--ram 4096 \
--disk path=/data/pools/ubuntu1804.img,size=20,bus=virtio \
--vcpus 2 \
--os-type linux \
--os-variant ubuntu18.04 \
--network bridge=virbr0 \
--graphics none \
--console pty,target_type=serial \
--location '/data/images/ubuntu-18.04.2-server-amd64.iso' \
--extra-args 'console=ttyS0,115200n8 serial' \
--force --debug
after finishing all the process, when i tried virsh console ubuntu1804, it is frozen, googled and tried a lot of different options, finally this one worked
sudo apt install libguestfs-tools
sudo virt-edit -d ubuntu1804 /boot/grub/grub.cfg
Replace all instances of quiet with quiet console=ttyS0 in the grub.cfg file and start my VM for console connect. then try to start the container and login again
virsh start ubuntu1804
virsh console ubuntu1804
after login, make sure update the grub
vi /etc/default/grub
change GRUB_CMDLINE_LINUX_DEFAULT=”quiet splash” to GRUB_CMDLINE_LINUX_DEFAULT=”quiet splash console=ttyS0″, then
sudo update-grub
