kvm tools: Increase AIO_MAX to 256

mirror of https://github.com/clearlinux/kvmtool.git synced 2026-06-16 02:15:47 +00:00

The queue size for virtio_blk is 256 and AIO_MAX is 32, we might be
short of available aio events if guest issues > 32 requests
simultaneously. Following error is observed when guest running stressed
I/O workload.

  Info: disk_image__read error: total=-11

To fix this, let's increase the aio events limit.
