Public bug reported: Recent versions of VMware vSphere support a "virtual watchdog timer", which implements a watchdog timer in the hypervisor. We use this with Patroni to ensure that a VM will reboot rather than accidentally have a writeable database when it shouldn't.
Linux supports the virtual watchdog timer through the "wdat_wdt" module. In Ubuntu 24.04 LTS on amd64, this module is in the "linux-modules- extra-*-generic" series of packages. These are depended on by the "linux-image-generic" package, but not by the "linux-image-virtual" package. The latter is what is included in Ubuntu Official Cloud Images, including the OVA version for vSphere. I think that installing "linux-image-virtual" on amd64 should get you the "wdat_wdt" module because it's necessary to fully support a common hypervisor. This would probably entail moving it from linux-modules- extra-*-generic to linux-modules-*-generic.
