virt-manager-3.0.0.tar.bz2
* virt-install –cloud-init support (Athina Plaskasoviti, Cole
Robinson)
* The virt-convert tool has been removed. Please use virt-v2v
instead
* A handful of UI XML configuration options have been removed.
The XML editor can be used instead. For a larger discussion see
this thread: https://www.redhat.com/archives/virt-tools-list/
2019-June/msg00117.html
* The ‘New VM’ UI now has a ‘Manual Install’ option which creates
a VM without any required install media
* In the ‘New VM’ UI, the network/pxe install option has been
removed. If you need network boot, choose ‘Manual Install’ and
set the boot device after initial VM creation
* ‘Clone VM’ UI has been reworked and simplified
* ‘Migrate VM’ UI now has an XML editor for the destination VM
* Global and per-vm option to disable graphical console
autoconnect. This makes it easier to use virt-manager alongside
another client like virt-viewer
* virt-manager: set guest time after VM restore (Michael Weiser)
* virt-manager: option to delete storage when removing disk
device (Lily Nie)
* virt-manager: show warnings if snapshot operation is unsafe
(Michael Weiser)
* Unattended install improvements (Fabiano Fidêncio)
* cli: new –xml XPATH=VAL option for making direct XML changes
* virt-install: new –reinstall=DOMAIN option
* virt-install: new –autoconsole text|graphical|none option
* virt-install: new –os-variant detect=on,require=on suboptions
