[Qemu-devel] implement lvm-aware P2V to reduce time cost significantly for linux server

[Haoyu Zhang]

Hi,

I want to P2V a redhat server to kvm vm, and lvm was used to manage disks in the redhat server.

I want to only migrate the really used storage to vm image, which can reduce the time cost significantly sometimes,

so I need the information of logical volume to physical disks bitmap, to know which physical sectors were really used, 

any ideas?

Is there a tool off-the-shelf have implemented the target?

Thanks,

Zhang Haoyu
