Hi Holger, you can find a patch to make g-i-installation jobs faster by switching from disk image files to logical volumes on "experimenting" branch. Requirements: - add a disk (or resize current one to get a new partition). Size depends on how many concurrent g-i-installation jobs there are/will be. - once attached (we'll name it /dev/vda): # pvcreate /dev/vda # vgcreate jenkins01 /dev/vda Thanks for considering. -- G..e
