Re: RBD snapshot format
Hi Wido, I didn't see the format information for snapshots stored in the database, so I'm assuming it references the associated volume format. I assume the cleanest way to get around that would be to have a separate format field for snapshots, but that wouldn't really make sense just for this one use case. Another way would be to just have the restore (create template from snapshot, etc.) function always assume QCOW2 for RBD snapshots, but that's dirty, and would cause problems for existing snapshots. It seems like the best method would be to have the restore function look at the actual file to get the format information instead of pulling it from the database, though I'm not sure if that's even possible. Does anyone else have any thoughts or suggestions?

I can submit a patch for that, but I wanted to make sure there wasn't some other reason for the RAW output first. No, that won't work. Because the management server will then still think it's in RAW format and store that in the database. It has been a long time since I looked at this. I know I did some work in this area and made some patches.

I think this is due to the NFS snapshots being output/uploaded in QCOW2 format, while RBD snapshots are output in RAW format. It appears that even when using sparse RAW files they are uploaded to S3 with the 'allocated' size instead of the sparse size. The problem here lies in the code in CloudStack. Since the source volume is in RAW format, the snapshot also becomes QCOW2. I remember that I wrote some patches for this, you might want to look in the Git history. My question is: Is there a good reason for RBD snapshots to be output as RAW instead of QCOW2? It appears that QCOW2 templates are automatically converted when deploying them as RBD, so that shouldn't be a problem. The only downside I can think of would be having to convert the RAW RBD data to QCOW2 as an extra step when creating snapshots, but even that seems like it would take less time than uploading the RAW images to S3. Thoughts? Like I said, I think I wrote patches for this. Qemu-img is used to convert the RAW RBD into the snapshot, so QCOW2 should be no problem as output format. But the code in CloudStack seems to assume that the snapshot volume is always the same format as the source. Wido P.S.: I'm on vacation in Norway at the moment, so I'm pretty laggy with replying.

Re: [DISCUSS] we need a better SSVM solution
Paul, For your #1, there is this page [1] that might be a bit outdated but the system-vm section is fairly complete. but effectively things could be better address. I know there is currently an initiative on changing how configuration are sent to VR and system-vms. theres was some discussions at CCCEU14 on this. I think it would be interesting to have a design spec in the wiki about it. Also, the way the sysvm is currently provision kind of make sense, look like it's a basic debian templates, cloudstack push a system.iso into at when VR, SSVM, CPVM are created, the iso contain all latest scripts from the cloudstack-management server. the system iso can also be modified if required (ex to install xentool in VR). it's far from being perfect, but might worth digging into the current deployment method? I would add to the current discussion this : Our current method of build system-vm templates used by the community is becoming outdated, the way we generate generic system-vm template is due for an update, as example we use veewee which might worth replacing this by vagrant... also, we should be able to embed xentools or vmware tools inside the templates... I haven't found much documentation on how to customize system vm templates (ex: send cloud.log into a syslog server) but I think it's something we can do with the current system.

RE: [DISCUSS] we need a better SSVM solution
...also. I'm not a fan of us different configuration processes for different hypervisors. I'm fairly sure that where the hypervisor still uses the systemvm.iso it overwrites the scripts which are already on the system vm, whereas with xenserver we only inject config in through pvgrub. I think that the systemvm.iso should only contain the same data as is injected via xenserver for consistency, or xenserver system vms should go back to using systemvm.iso There are a load of global settings which allow you to specify the system vm template for each hypervisor, I guess this effectively allows you to have different router templates to the ssvm/consoleproxy template. router.template.vmwareName of the default router template on Vmware router.template.xenName of the default router template on Xenserver I'm not sure why it exists, you can't change the ssvm or cpvm template per hypervisor.

Having ACS act as a CA would be quite interesting for some things. It’s one of the reasons I’ve pondered a “hook” in the past to notify 3rd party upon VM creation/deletion/etc. Wonder if we could take advantage of dogtag or similar. All that said - setup/management of a CA is a PIA and probably outside scope of ACS, unless you did a “light” one similar to Puppet by default... An aside on that “hook” idea - something scriptable similar to (I said “similar to, no flames!) systemd for this could be interesting. A good portion of users would resist having an agent installed on the user VM, but I guess we’re in that position already, and they just wouldn’t get the added functionality. One user experience point: Almost every time Parallels comes out with a new version, I have to update their agent on my VMs, which on the Windows side means a reboot. That gets old, and I’ve only got a handful of win VMs there... Going to see if I can puppet-ize one of the SSVMs over the weekend to see what other thoughts come up.

Re: Database locking code
Hi,
That looks like it will work for my purposes. When I have the time to
continue the task I was working on yesterday I will try this way.

I wrote that example code from memory, but now that I think about it, you
wouldn't call the lock method in the try block.
Call lock and if you're successful, entry a try block to do your work and
have a finally to unlock and release the lock.

I have some code I've added to CloudStack that I am currently
synchronizing on in the traditional manner (synchronized block,
ExecutorService, etc). I'm currently running a single instance of
CloudStack so I don't have to deal with clustering.
I've read the Data Access Layer documentation and am wondering if the
database locks are the actual appropriate solution rather than what
I'm doing.
Basically my issue is that I need to lock access to an IP address
reserved to the account and perform some long operations on it. I also
need to guarantee that no other IPs on the account are manipulated
while performing this task. Synchronization accomplishes this because
I can force the IP operations through an ExecutorService, but I'm
really looking for a better solution that will also work with
clustered management servers.
Thanks,
Jeff
