You got sanlock.service that notifies the engine when a storage domain is unaccessible for mode than 60s. Libvirt also will pause a VM when a pending I/O cannot be done. >In an event of self recovery of the storage backend what happens next? Usually the engine should resume the VM, and from application perspective nothing has happened. >Manual intervention is required? The VMs may be down or they just >continue to run?
