Hi, The following command gives me the error in the title. Does anybody know how to specify the file format? Thanks. sudo virt-install -n web_devel_qcow2_name -r 4096 --disk path=/tmp/web_devel_qcow2,bus=virtio,size=1,format=qcow2 -c ~/iso/ubuntu-13.10-server-amd64.iso --network bridge=br0,model=virtio --graphics vnc,listen=0.0.0.0 --noautoconsole -v https://www.suse.com/documentation/sles11/singlehtml/book_kvm/book_kvm.html#tip.libvirt.config.pci.virsh.managed Also, I found the following explanation on the above page. But I don't quite understand it. Does "managed" only applies to PCI devices (hence not disk)? Thanks. libvirt recognizes two modes to handle PCI devices: they can be either 'managed' or 'unmanaged'. In the managed case, libvirt will handle all the details of unbinding the device from the existing driver if needed, resetting the device, binding it to pci-stub before starting the domain, etc. When the domain is terminated or the device is removed from the domain, libvirt will unbind from pci-stub and rebind to the original driver in the case of a managed device. If the device is unmanaged, the user must take care to ensure all of these management aspects of the device are done before assigning it to a domain, and after the device is no longer used by the domain. -- Regards, Peng _______________________________________________ virt-tools-list mailing list virt-tools-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/virt-tools-list
