# The kernel allocates aio memory on demand, and this number limits the
|
|
# number of parallel aio requests; the only drawback of a larger limit is
|
|
# that a malicious guest could issue parallel requests to cause the kernel
|
|
# to set aside memory. Set this number at least as large as
|
|
# 128 * (number of virtual disks on the host)
|
|
# Libvirt uses a default of 1M requests to allow 8k disks, with at most
|
|
# 64M of kernel memory if all disks hit an aio request at the same time.
