Re: [libvirt] [libvirt-users] LVM Volume Creation

Hi All, I'm having issue with creating LVM Volume via libvirt. We are running libvirtd 1.2 with KVM. We are creating Volume Group (VG01) outside of libvirt and defining a storage pool for it. Here is the StoragePool XML for the Volume Group created outside libvirt. <pool type="logical"> <name>VG01</name> <target> <path>/dev/VG01</path> </target> </pool> We are creating Logical Volume (ub_test01.img) through libvirt in the Volume Group (VG01) Here is the XML to create Storage Volume in LVM Storage Pool VG01. <volume type="block"> <name>ub_test01.img</name> <allocation>0</allocation> <capacity unit="M">1</capacity> <target> <format type="lvm2" /> </target> </volume> When I create the Logical Volume from libvirt using above XML and run lvs command to list logical volumes, this is what I see. LV VG Attr LSize Origin Snap% Move Log Copy% Convert --------------- ------- ------- ------- ----------------------- ------- ------- ------- ------- ------- foo VG01 -wi-a- 1.00g ub_test01.img VG01 swi-a- 4.00m [ub_test01.img_vorigin] 0.20 root ops-02 -wi-ao 227.08g swap_1 ops-02 -wi-ao 5.75g As you see, ub_test01.img shows that it has an Origin indicating that it was created as a snapshot, but, that Origin doesn't exist and wasn't specified. I'd appreciate if you anyone can help me understand what is going on and/or describe how to make libvirt create logical volumes not as a snapshot. I'm happy to enable debugging to see what command libvirt is running to create the volume if someone case describe how to enable debugging.
