Re: [Kimchi-devel] [PATCH] vmstorages changes for Power: allow SCSI devs, block IDE devs

Kimchi does not allow scsi devices to be attached in a VM (devices with names sdb,sdc ...). A simple change in API.json regex of vmstorages_create fixes it. At the same time, Power systems does not support IDE devices and adding devices with 'hd[b-z]' name have unpredictable results. This patch also adds a backend verification to avoid this scenario.
