+----+------+-------------+------------------+------+--------+ | ID | Name | Disk Format | Container Format | Size | Status | +----+------+-------------+------------------+------+--------+ +----+------+-------------+------------------+------+--------+ |
[2] | For example, Create a Virtual Machine image of Fedora 22 for adding. |
# create a disk image [root@dlp ~]# qemu-img create -f qcow2 /var/kvm/images/fedora22.img 10G
# Install [root@dlp ~]# virt-install \
Starting install...
--name fedora22 \ --ram 2048 \ --disk path=/var/kvm/images/fedora22.img,format=qcow2 \ --vcpus 2 \ --os-type linux \ --os-variant fedora22 \ --graphics none \ --console pty,target_type=serial \ --location 'http://ftp.jaist.ac.jp/pub/Linux/Fedora/releases/22/Server/x86_64/os/' \ --extra-args 'console=ttyS0,115200n8 serial' # installation starts |

After installation, change settings in virtual machine like follows and shutdown it.
* delete or comment out the line "HWADDR" and "UUID" in /etc/sysconfig/network-scripts/ifcfg-eth0 * set "dhcp" for "BOOTPROTO" in /etc/sysconfig/network-scripts/ifcfg-eth0 |
[4] | Add the virtual image to Glance. |
