[pve-devel] [PATCH manager 2/4] ui: lxc/qemu: add disk reassign

Aaron Lauterer a.lauterer at proxmox.com
Fri Nov 12 10:53:33 CET 2021


For the new HDReassign component, we follow the approach of HDMove to
have one componend for qemu and lxc as they are the same for most parts.

The 'Move disk/volume' button is now a SplitButton which has the
'Reassign' button as menu item.  In the lxc resource panel the menu item
is defined extra so we can easily disable it, should the selected mp be
the rootfs.

In the lxc resource and qemu hardware panel we currently add a new
button to handle unused disks/volumes. The button is "switched" with the
'Move' in this case. The width of the buttons is aligned to avoid
movement of other buttons.

Once we are able to also move unused disks/volumes to other storages, we
can remove this.

The handling of the value for the pmxDisplayEditField is a workaround as
apparently it is not possible to bind the value. Therefore the value is
initially set with a cbind and the viewModel of HDReassign is updated in
the change handler of the pmxDisplayEditField.

Switching the move button with the reassign button in the lxc resource
and qemu hardware panel works and the button following does not change
position. I did notice though that the split button of the same width is
apparently rendered slightly different and the right end moves by about
1px.
