[Kimchi-devel] [PATCH] Issue #363: Fix data/information consistence in edit template window

[Rodrigo Trujillo]

This patch changes edit template window to fix consistence:
- Show storagepool + volume name correctly in storagepool field after
  saving
- Show disk size according to storagepool or storagepool/volume selected
- Block disk size input box when disk is type volume (iscsi/scsi volumes
  cannot be changed)
