I have a "standard" script I use to automate virt-install: ---------------------------------------------------------------------- #!/bin/bash - # Script used to install VMs. # You have to lvcreate the disk first! # lvcreate -L 10G -n $name vg_data set -e name=F16x64 cpus="--cpu=host --vcpus=4" disk="--disk path=/dev/vg_data/$name" #location="-l http://www.mirrorservice.org/sites/download.fedora.redhat.com/pub/fedora/linux/releases/15/Fedora/x86_64/os/" location="--cdrom /mnt/media/installers/Fedora-16-x86_64-DVD/Fedora-16-x86_64-DVD.iso" type="--os-type=linux" variant="--os-variant=fedora16" #graphics="--graphics spice" #options="-x btrfs" #extra="" virt-install -n $name -r 1024 \ $cpus $type $variant $disk $location $graphics $options $extra ---------------------------------------------------------------------- By making small adjustments to this, I can install all guests I need. > I think size=200 is maybe not needed, as the LV has already be created. Right? > format=raw seems weird to me and not needed. Right? You don't need size or format since virt-install will pick that up from the disk image itself. > My host has 16G RAM. Shall I put 16 as --ram argument or stay with 8 ? Depends how much you need for the *guest*. It needs to be smaller than the host size, but will depend on how many concurrent guests you want to run. > How about the filesystem? I want an ext4.

No, the guest installer deals with all that. > Not sure about the --accelerate argument --accelerate is not required with modern virt-install.
