Description Doron Fediuck 2013-04-03 16:54:48 UTC
Description of problem:
Qemu supports a virtual watchdog device which can be used to reset or pause a guest. This is already supported in vdsm API, and we're missing the engine side.


Additional info:
There are cases where the guest will crash but libvirt will report the VM is up.
In such cases the engine fails to handle properly HA VMs.

Comment 7 Lukas Svaty 2013-07-26 10:13:59 UTC
as the action "none" is available also default watchdog model should not be set to blank but set to "none" instead

Comment 8 Lukas Svaty 2013-07-26 10:17:25 UTC
also watchdog action field should be available for user after adding watchdog model

user is able to choose:

watchdog_model: ""
watchdog_action: "reset"
