[pve-devel] [PATCH v4 manager] HDEdit: check iothread by default and move it from advanced section

[Matthias Heiserer]

Existing disks are not changed by this.
Especially in benchmarks, iothreads significantly improve IO performance.

Signed-off-by: Matthias Heiserer <m.heiserer at proxmox.com>

Changes from v3:
* remove automatically switching to/from SCSI single when iothread is (un)checked
* iothread will be initially set on
* changing the controller to something other than SCSI single and then back to
  SCSI single will enable iothread for all SCSI disks.

Changes from v2:
* also check iothread when adding a disk to an existing VM and 
 scsi single
* use bind instead of hardcoded true
