如何挂载qcow2 镜像文件中的的 lvm 分区
一个qcow2格式的文件vm07.qcow2 ，里面有lVM分区，如果挂载呢？
# modprobe nbd max_part=16
# qemu-nbd -c /dev/nbd0 vm07.qcow2
# partprobe /dev/nbd0
# fdisk -ul /dev/nbd0
Disk /dev/nbd0: 180.4 GB, 180388626432 bytes
255 heads, 63 sectors/track, 21931 cylinders, total 352321536 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x0007e2d5
Device Boot Start End Blocks Id System
/dev/nbd0p1 * 2048 1050623 524288 83 Linux
Partition 1 does not end on cylinder boundary.
/dev/nbd0p2 1050624 9439231 4194304 82 Linux swap /
Solaris
Partition 2 does not end on cylinder boundary.
/dev/nbd0p3 9439232 37748735 14154752 8e Linux LVM
求教，thx.

你可以先active
lvchange -ay /dev/VolGroup/lv_root
然后在执行挂载：
mount /dev/VolGroup/lv_root /mnt
