Hello, I`m trying qcow2`s shapshot property last haft day. I catch strange problem after creating some snapshots.
Look:
VE is ruunning.
root@kvm2:/vz/images/121# qemu-img info vm-121-disk-1.qcow2
Now I`m creating snapshot..
Ok, lets Look what we gave.
Whats it is?
I repeat same procedure on various qcow2 files about five times and got very interesting things. =)
For example:
Of cause after this no one snapshot can be applies or deletes. =(
My pveversion:
root@kvm2:/vz/images/121# pveversion -v
If someone test this property plz get we know.
Thanks.
