Hi, here is my v4 patch-set update to the v3 RFC submitted on Nov 27th. When an active virtio block device is hot-unplugged from a KVM guest, affected guest user applications are not aware of any errors that occur due to the lost device. This patch-set adds code to avoid further request queueing when a lost block device is detected, resulting in appropriate error info. Additionally a potential
