I am sorry, i can not understand what you said just now.
My architechure is:
Windows7-Guest
|
libvirt
QEMU-KVM
|
CentOS7-Host
I make lv on Host, then attach it to Guest.
And then login Guest, initialize it(MBR), format it(NTFS), write something to
it, shutdown Guest.
Finally, I try to mount this lv using ntfs-3g, but failed.
That all.
Thans anyway:)
Regards!

Do you use the same virtualization stack on Linux and Windows ?
