"how does openstack calculate the vcpu hours and total disk usage hours?"
I created a cirros vm with flavor of m1.tiny without further operation on
that vm.I created it around 2 hours ago but on the dashboard"Overview", it
shows that "This Period's VCPU-Hours: 44.95 This Period's GB-Hours: 44.95
This Period's RAM-Hours: 23014.62"

Does anyone know how openstack come up with these numbers?I mean
VCPU-Hours, GB-Hours and RAM-hours?I just created a very small
cirros vm without any further operations.How can this number look so big?

Thank you very much.

how do we install virtio drivers if its missing? How do I verify it on
the centos cloud image if its there?

Unless it’s a very very ancient unsupported version of centos the virt-io
drivers will be in the kernel package.
Do a lsmod and look for virtio to check if it is loaded.

Regarding the slower speed of the custom image:
First check if they are really the same file format and one is not
secretly a raw file:
file centos.qcow2

I would expect the virt-sparsify to be indeed the way to go.
Although I think that cinder will convert it to raw for you and you
probably want that for ceph (IIRC it is a setting).
It might be that the centos downloaded file is actually RAW so it does not
need to convert that.

You can also check the cinder server debug log / load or ceph load to see
if something is bottlenecked during the upload to maybe get a hint to what
the problem is.

Cheers,
Robert van Leeuwen
