Ubuntu 13.10 KVM: build VMs without VNC by using virt-install

Here are logs when building VMs via virt-install without VNC.

# virt-install --version 0.600.4

error..

# virt-install --name ubuntu1204-varm -r 1024 --vcpus=2 --os-type=linux --os-variant=ubuntuprecise --disk path=/var/lib/KVM_images/ubuntu1204-varm.qcow2,size=10,format=qcow2 --cdrom  /home/hattori/ISO_files/ubuntu-12.04.1-server-amd64.iso --accelerate  --nographics --network network=default,model=virtio --hvm --extra-args='console=tty0 console=ttyS0,115200n8 serial' ERROR    --extra-args は --location とともに指定する場合のみ機能します。

when using --extra-args option, I need to use --location instead of --cdrom option.

I need to specify nfs or http or ftp path when using --location.

nfs:host:/path or nfs://host/path             An NFS server location containing an installable distribution image         http://host/path             An HTTP server location containing an installable distribution image         ftp://host/path             An FTP server location containing an installable distribution image

To specify http path, create a directory to mount ISO

# mkdir /var/www/mnt

mount the ISO

# mount -t iso9660 -o loop /home/hattori/ISO_files/ubuntu-12.04.1-server-amd64.iso /var/www/mnt mount: block device /home/hattori/ISO_files/ubuntu-12.04.1-server-amd64.iso is write-protected, mounting read-only # ls /var/www/mnt/ boot          dists  efi      isolinux    pics  preseed             ubuntu cdromupgrade  doc    install  md5sum.txt  pool  README.diskdefines

start apache2

# apache2ctl start

Now, you can specify installable image over http.

try again.

Okay, I can install ubuntu via console without VNC.
