Async IO setting for cloud-init drive

[gurubert]

Hi,

it would be nice to be able to set the Async IO option (aio=) for cloud-init drives in the GUI.

We are running a shared storage on a SAN LUN with OCFS2 and we know this is an unsupported setup.

Since kernel 6.5 we need the aio=threads parameter for virtual disks. For normal vHDDs this can be done via the GUI, but not for cloud-init drives.
We can add the parameter manually in the config file for the VM but this is kind of tedious.

Hi. There is also problems with lvm over iscsi. There should be a settings for datacenter level default async IO option.
