Re: [pve-devel] [RFC manager/container/qemu-server/guest-common 0/4] fix #4474: stop tasks may overrule shutdown tasks

[Friedrich Weber <f.weber@proxmox.com>]

Lost track of this a bit, reviving due to user interest [1].

As the series does not apply anymore, I'll send a new version in any
case, but wanted to ask for feedback before I do.

My questions from the cover letter still apply:

Actually I don't really like the second modal dialog. What about the
following: When the user clicks "Stop" and the frontend detects an
active shutdown task, the already-existing "Confirm" dialog has an
additional default-off checkbox "Kill active shutdown tasks" (or
similar). This way the default behavior does not change, but users do
not have to kill active shutdown tasks manually anymore.
