Hi all, The current 'New VM' wizard has clearly started to show its age. The original design was largely based on xen specific assumptions and the state of libvirt/virtinst at the time: many of those assumptions don't apply today, or require a bit more thought since we now support both xen and qemu based VMs. You can find a patch for a new implementation of the 'New VM' wizard here: http://fedorapeople.org/~crobinso/virt-manager/newvm2/virt-manager-newvm-01.patch I hope you'll agree it's a much simpler and usable layout, without sacrificing functionality (even laying the groundwork for future improvements). This design was largely done by Tim Allen (former Red Hatter) and Jeremy Perry (current Red Hatter), so a big thank you to them. One of the biggest changes from the old design is that we don't ask upfront about paravirt vs. fullvirt, VM architecture, or qemu vs. kvm vs. xenner. For new users, this has been an endless pain point ("Why can't I install a PV kvm guest?" among others) and is really a distinction we don't need to force on people upfront: we are certainly in a position to choose sensible defaults (and for kvm, paravirt/virtio has always been setup in the background depending on what OS version is being installed). The logic for the defaults is as follows: - For the qemu libvirt driver, use the first available of the following: kvm, plain qemu, xenner. - For the xen libvirt driver, use paravirt if the user selects a URL install and the tree supports it, otherwise use fullvirt. - Always default to the host architecture for new VMs. We allow the user to deviate from these defaults in the final screen under the 'Advanced Options' section. Also, you'll notice there is a generic 'Computer' icon in the wizard header: this will soon be replaced by a custom icon. So, some screenshots!

Having the 'name' box occupy an entire page by itself was also a bit overkill, so we did away with that as well. The one new piece here is the option to choose the libvirt connection to install on. Rather than have the 'New' button on the main manager window be conditionally sensitive, the user can now always launch the wizard, choosing the connection from there. If there is only 1 active connection, the drop down will appear as a label.

This hasn't deviated much from the current options: the one difference is that the OS Type/Variant drop downs will always be here. This will allow us in the future to offer automatic distro detection per selected install media (we may have this for URL installs by the time the release goes out). Since PXE installs require no extra input, the screen will only have the OS Type/Variant option listed. Page 3: CPU + Mem details http://fedorapeople.org/~crobinso/virt-manager/newvm2/newvm-pg3-1.png We dropped the max memory vs. default memory split in the existing wizard: this doesn't have much meaning the qemu/kvm world, and even for xen isn't something that needs to be asked up front. The user can always change it later. Also, rather than list tons of warning information about overcommitting vcpus, we simply cap the amount at the number available on the host. If for some reason a user wants to allocate more than the host amount of virtual cpus to a VM (say for development purposes) it can easily be done post-install. Page 4: Storage http://fedorapeople.org/~crobinso/virt-manager/newvm2/newvm-pg4-1.png The main change here is that we removed the block device vs. file device dichotomy: we are pretty capable of determining this distinction behind the scenes. The option is also now available to skip adding storage altogether: this is useful in the case of Live CDs or diskless PXE booting. When adding storage though, the two options are now: 1 - "Create a disk image on the computer's hard drive": We set up a libvirt storage pool behind the scenes to point to the default location (if using PolicyKit or running as root, this is /var/lib/libvirt/images) and allocate a disk image based on the requested size. In the future, the default location will be configurable with a global preference. 2 - "Use managed or other existing storage" : This allows pointing to an existing path, or provisioning more complex storage on demand (this is dependent on a libvirt storage API aware browser dialog, which is ongoing work. For the time being, this just launches a local GTK file browser). The one piece not shown here is the option to choose sparse Vs. non-sparse. We will be putting this back in before the final version is done. Page 5: Summary and Advanced Options http://fedorapeople.org/~crobinso/virt-manager/newvm2/newvm-pg5-1.png http://fedorapeople.org/~crobinso/virt-manager/newvm2/newvm-pg5-2.png http://fedorapeople.org/~crobinso/virt-manager/newvm2/newvm-pg5-3.png The summary section is pretty straight forward, no surprises here. The 'Advanced Options' section encompasses networking, hypervisor, and architecture options. The hypervisor and arch defaults were explained above. For networking, the default is: - A bridge device if any exist, else - Virtual Network 'default' (comes out of the box with libvirt), else - First available virtual network, else - no networking! This logic will be globally configurable at some point, if you wanted to use a specific bridge device or virtual network for all new VMs. We also decided to put all the available networking options into 1 drop down, rather than have 2 separate sections for bridges vs. virtual networking. I think that covers all the significant bits, hopefully other than that the screenshots speak for themselves. Any feedback is appreciated: none of this set in stone.
