Dear Cloudstack users,
Can someone explain me roughly the process of creating an snapshot in KVM ?
The process takes a very long time, the speed at what the qcow2 file is
copied from primary to secondary storage is extremely slow, on the storage
level
I can see is around 4 Mbps but I know our primary storage and secondary can
dump data faster than that
So far this is what I know
Step
1.- Pause the VM in the host
2.- Create the snapshot of the qcow2 files using qemu-img
3.- Backup the image into secondary storage
So my question is who is actually copying that file over to secondary
storage ?
I've checked the secondary storage vm and it doesn't look like its playing
any role during this process.
Thanks in advance
