Today my friend asked me, how can he set “timeout” value for his KVM guest which uses virtio disks. ?.
In guest, virtio devices will be represented as “vd{a,b,c..} devices..
He experienced to set that value for a scsi device (ex: echo 180 > /sys/block/sdd/device/timeout) ..
My answer was, it is NOT required , so does not exist. There is no option to set that “timeout” value for virtio devices in qemu + kvm setup..
