Subject Re: [jira] [Updated] (CLOUDSTACK-67) Resizing
Date Thu, 13 Sep 2012 04:36:46 GMT
I mainly wanted to send out some feelers to see if there was an
imminent branch merge or something. If not, I'll clean up mine a bit
and let people have a look. I haven't looked into changing the UI yet
at all, and since it seems there's a redesign in progress maybe I'll
hold off. The API pieces are all there and work in my test
environment. There are a few things I had to work around, for example
it seems we're missing java bindings for key libvirt calls, which I
implemented via host script instead if your version of libvirtd/virsh
supports it.

A few questions:

Is all KVM storage that's file based automatically qcow2 in
cloudstack? That would be NFS and local, are there others?  It should
be simple for me to add those in and do some testing I think, although
qemu-img needs to be a specific, fairly recent version to support
qcow2 resizing.

Which reminds me, cloudstack no longer bundles or requires a custom
qemu-kvm package, correct? Seems like it did at one point.

Wido, I've played with Ceph a bit and RBD, but it's been maybe a year.
Is resizing of the RADOS device handled well? Have you played at all
with resizing the block device file of a live VM and then issuing a
'virsh blockresize'?

this moment, but at least, the backend code should be ok.
