Confirming health checks work
-
I understand Health Checks wait for the management tools to load however I have a device being backed up that does not have these management tools loaded yet still passes.
How is this possible?

Hi,
Can you copy the result of
xe vm-param-list uuid=<UIID of this VM>and paste it here? -

It's a FreeBSD, so the PV drivers are bundled in the kernel. Maybe that's enough for XO to detects when they are loaded by populating the Xen store.
Let me ask @Bastien-Nollet to review a bit of the logic behind the tools detection
-
@olivierlambert I think you're right, we just wait for the XAPI field
PV_drivers_detectedof the restored VM's guest metrics to be true. -
So that explains it then
Free BSD boots and since the kernel loads successfully the PV drivers, it's fine by us. -
Good to know the management agent is not required on FreeBSD (pfSense)
-
It's better to have it to get handy options like IP addresses displayed and so on.
