Mengawinkan Libvirt dengan Ubuntu Cloud Image
- Unduh dan tweak Ubuntu Cloud Image seperti yang pernah saya tuliskan di sini.
- Persiapkan meta data asperti yang dituliskan di sini : http://blog.oddbit.com/2015/03/10/booting-cloud-images-with-libvirt/ atau gunakan skrip https://github.com/larsks/virt-utils/blob/master/create-config-drive
root@studio:~# wget https://github.com/larsks/virt-utils/raw/master/create-config-drive root@studio:~# chmod +x create-config-drive
- Jalankan dengan :
root@studio:~# ./create-config-drive -k /home/samsul/.ssh/id_rsa.pub -u user-data config-virt-install.iso adding pubkey from /home/samsul/.ssh/id_rsa.pub generating configuration image at config-virt-install.iso
- Salin berkas
root@studio:~# virsh vol-list default root@studio:~# cp xenial-server-cloudimg-amd64-disk1.img /var/lib/libvirt/images/ root@studio:~# /etc/init.d/libvirt-bin restart root@studio:~# /etc/init.d/libvirt-guest restart root@studio:~# virsh vol-list default Nama Path ------------------------------------------------------------------------------ blankon-clone.qcow2 /var/lib/libvirt/images/blankon-clone.qcow2 blankon.qcow2 /var/lib/libvirt/images/blankon.qcow2 generic-clone.qcow2 /var/lib/libvirt/images/generic-clone.qcow2 generic.qcow2 /var/lib/libvirt/images/generic.qcow2 vps-template-ubuntu16.04.img /var/lib/libvirt/images/vps-template-ubuntu16.04.img
- Jalanlankan Install
root@studio:~# virt-install -n vps-utemplate -r 2048 -w network=netw1 --disk vol=default/vps-template-ubuntu16.04.img --import --disk path=/home/samsul/Unduhan/ISO/Ubuntu/config-virt-install.iso,device=cdrom Starting install... Creating domain... | 0 B 00:00:01 Domain creation completed.
