Hello guys,
I was hoping to have some feedback from the community on the subject of having
an ability to keep snapshots on the primary storage where it is supported by
the storage backend.
The idea behind this functionality is to improve how snapshots are currently
handled on KVM hypervisors

Hi Andrija,
The way I understand it (and have seen in practice) is that by default
the MGMT server will use any available server for HA. Setting the HA
tag on a hosts just dedicates that host to HA, meaning that during
normal provisioning no VMs will use that host, it will only be used
for HA pur
I agree...and understand :)
But would this means, that VMs will not be provisioned anywhere during HA
kicking in ? I guess so...
So I avoid having started another copy of the same VM, that is alrady
running on disconnected hosts - I need this as the temporary solution,
during CEPH backfilling, so
We have such a weird way of storing storage tags in the DB.
They get stored as individual rows in the storage_pool_details table (which
is fine). If the value in the "value" column is "true", then we assume the
"key" column contains the name of a storage tag.
This makes it more difficult than it

Hi Mike,
I think the interest in this issue is primarily for Ceph RBD, which
doesn't use iSCSI or SAN concepts in general. As well I believe RBD
is only currently supported in KVM (and VMware?). QEMU has native RBD
support, so it attaches the devices directly to the VMs in question.
It also nati
Yeah, I think it's a similar concept, though.
You would want to take snapshots on Ceph (or some other backend system that
acts as primary storage) instead of copying data to secondary storage and
calling it a snapshot.
For Ceph or any other backend system like that, the idea is to speed up
snapsh
For example, Punith from CloudByte sent out an e-mail yesterday that was
very similar to this thread, but he was wondering how to implement such a
concept on his company's SAN technology.

Hi Punith,
I sent this e-mail (below) in a different CloudStack dev@ thread, but it
seems they are only interested in RBD in that thread, so I will include

Hey Ian,
Since it looks like the intent of this particular thread is just to discuss
RBD and snapshots (which I don't think your business uses), you would be
more interested in the "Query on snapshot and cloning for managed storage"
thread as that one talks about this issue at a more general level
Hi Mike,
I agree it is a general CloudStack issue that can be addressed across
multiple primary storage options. It's a two stage issue since some
changes will need to be implemented to support these features across
the board, and others will need to be made to each storage option.
It would be n
Hi,
Quick question, using the API, how would a user remove an associated SSH

on the existing API calls.
Furthermore, how can we change the SSH Key? Is it the

Thanks.

Agree with Logan. As fans of Ceph as well as SolidFire, we are interested
in seeing this particular use case (RBD/KVM) being well implemented,
however the concept of volume snapshots residing only on primary storage vs
being transferred to secondary storage is a more generally useful one that

Well...count me in on the general-purpose part (I'm already working on that

If someone is interested in implementing the RBD part, he/she can sync with

from a general-purpose standpoint.

Whatever way you think makes the most sense.
Either way, I'm working on this for XenServer and ESXi (eventually on KVM,
I expect) for managed storage (SolidFire is an example of managed storage).

Resets the SSH Key for virtual machine. The virtual machine must be in a
"Stopped" state. [async]"
Apologies for causing you extra stress. We all had a long Monday.
I also never used this function before and here's how I tested.
- empty or move /root/.ssh/authorize
Thanks for looking at it and testing it.
That answers the key replacement. Looks like there is no way to actually
removing the key from a created VM. I believe the only way left is the
deletion. The updateVM call won't update it either :S

Depending on what you actually want to achieve, you could also register a bogus
