Hello,
Does anyone have any (good) experience of the following:
I am using a single node (kvm+sunstone) using local storage.
VM disks are created using fs_lvm driver.
So, when instantiated, the “raw” image was dd to the logical volume, and every thing is smart.
But, if I power off (plug out the power) the node, and restart ?
All the logical volumes are still present and available, but on VM restart ? does the dd will overwrite the data ?
or any conflict that will make the vm unstartable ?
I have not verified yet into the drivers.
Thank you for your answer 
Regards,
Nicolas.
