Hi I'm using Gentoo Linux, libvirt-1.0.0, qemu-1.1.2-r3, multipath-tools 0.4.8-r1. After defining a new storage pool with pool-edit <poolname>: <pool type="mpath"> <name>mpath</name> <target> <path>/dev/mapper</path> </target> </pool> I get this: internal error missing backend for pool type 7 USE flags for libvirt package are: caps elibc_glibc iscsi libvirtd lvm lxc macvtap nfs nls python qemu udev vepa -audit -avahi -debug -firewalld -numa -openvz -parted -pcap -phyp -policykit -rbd -sasl -selinux -uml -virt-network -virtualbox -xen) What is wrong and what is the right way to map SAN LUN's to guest using multipath?
