Hi guys.

Without explicitly, manually using watchdog device for a VM, the VM (centOS
8 Stream 4.18.0-365.el8.x86_64) shows '/dev/watchdog' exists.
To double check - 'dumpxml' does not show any such device - what kind of a
'watchdog' that is?
The kernel can always provide a pure software watchdog IIRC. It can be
useful if a userspace app wants a watchdog. The limitation is that it
relies on the kernel remaining functional, as there's no hardware
backing it up.

many thanks Daniel
Is qemu's watchdog configurable just like on bare-metal? Perhaps same very way - via/in BIOS?
