connected by spice? by vnc to host or to guest? by rdp? by remote
debugging to it from a remote machine, by someone developing on it with
ssh, etc...
i agree the general use case you are describing make sense, but i rather
we model scheduling decisions directly if/where possible
Some parts of this thread are looking for perfection and on the way
creating additional tasks and reviewing cycles that are only remotely
related to the watchdog device;
Yes, we should try and reduce the existing differentiation between
desktop and a server.
No, this feature is not about closing that gap. Watchdog device is
about handling guest crash.
I strongly suggest that merging desktop and server dialogues will be
done as a different feature. The watchdog feature will take one step in
the 'right' direction- adding the (currently missing) HA tab into the
desktop dialog based on current design.
