I have a storage backend san disks, I have five servers which is KVM
hosted guests.
I am looking to clone an image of a guest machine, so I can use a new VM
form the image on a different server..
I am not sure what the best way. But when I do that, I get a memory
error, and need to xfs_repair and damages the original machine.
My steps are
One vm machine on the same server
* dd create original vm to template.img
* lvcreate -L 9G -n <vol-name> <pool>
* dd template.img to /dev/<pool>/<vol-name>
* virsh define <vm_name>.xml
another vm machine on the secondary server
* copy template.img to another server
* lvcreate -L 9G -n <vol-name> <pool>
* dd if=template.img of=/dev/<pool>/<vol-name>
* virsh define <vm_name>.xml
Nothing suspicious about these steps. So I'm suspecting that either
template.img is corrupt, or it does not fit into LV, or maybe it's in
use? I mean, if template.img is an image that's in use by a running
domain it doesn't necessarily contain valid state.
