Re: [libvirt-users] virt-manager - how to add /dev/mapper as a storage pool

Hi, I would like to be able to configure VMs running off dm-crypt devices that were unlocked in the host. Unlocked dm-crypt devices show up in /dev/mapper/devicename, with devicename being the second parameter given to cryptsetup luksOpen. The LVM storage pool type insists on searching in /dev/vgname and cannot be tricked into reading /dev/mapper by giving it a fake VG named mapper; the LVM storage pool type "dir" mishandles /dev/mapper/control ("illegal seek"). Is there a workaround to be able to use such devices in virt-manager without having to define a single storage pool for every device used? Greetings Marc
