Re: [cloudstack-devel] Hyper-V Support
Hi guys,
we are moving forward pretty fast in the development of support for Hyper-V, we'll be able to share the first bits hopefully very soon. :-)
In the meantime we have a small problem to solve with the secondary storage: in our test environment, we created a dummy Hyper-V resource, but we have troubles in deploying dummy instances as CloudStack cannot see and initialize a secondary storage.
Do you have any suggestion on how to get around that?
Thanks!

Usually only hypervisor host and storage system VM need to access to it, VMware does one special step that management server needs to access to it to bootstrap system VMs. So to support hybrid deployment option, we would require secondary storage to be accessible from all of them, giving the fact that Xen/KVM/VMware only supports NFS shares, it would be better to make secondary storage dual faces for Hyper-V, in this way, the same secondary storage will be able to serve XenServer/VMware/KVM/Hyper-V within the same zone.

>> CloudStack has two types of managing host. Agent based and manager based. Agent based means installing an agent on host and management server directly controls host through the agent. KVM and XenServer falls into this category, as KVM agent is written by CloudStack developer while agent of XenServer is provided by Xapi. The manager based approach applies to VMWare, HyperV, OVM3 where CloudStack invokes API of SDK provided by hypervisor vendor to communicate with *the manager*, for example, VCenter of VMWare, the manager is on behalf of CloudStack to control the host. in our code paths, these two approaches look like:

In GoF design patterns, the Resource is a proxy pattern that works as a surrogate between CloudStack and hypervisors.

Alessandro,
This is great to hear, I was actually planning on pinging you next
week to see how things were proceeding. I am thrilled to hear that you
are making rapid progress - any of the bits you have already in a
place that's public?

Hi Alessandro,
SSVM needs to have agent running which connects to MS on port 8250 (it is a remote agent). The responsibility of this agent is to take commands from MS and take some action.
One example of this is - MS instructing the SSVM to download a template on secondary storage and the agent doing to real work of downloading it.
You can just simulate an agent which can understand these commands to get going (Look at NfsSecondaryStorageResource.java for all the commands SSVM agent understands)
Thanks,
-Nitin

Hi Rajesh,
here's the error. It happens when we try to add a template. We need to find a way to replace this with a dummy implementation.
[java] WARN [storage.download.DownloadMonitorImpl] (http-8080-5:) There is no secondary storage VM for secondary storage host nfs://10.73.76.36/export/secondary
The fake secondary storage VM exists and is shown as in "Running" state in the admin panel.
Thanks!

Need to do the following:
1. Add a secondary CIFS resource, like NfsSecondaryStorageResource, which will be running inside SSVM. The main responsibility for this resource is to download templates from public network into CIFS storage. CifsSecondaryStorageResource is already in the code, but not sure what's status of it.
2. Add the CIFS code in your hyperv-v resource, for commands like, PrimaryStorageDownloadCommand(which will download template from CIFS storage)
3. Add CIFS support in AddSecondaryStorageCmd(the code is in discoverHostsFull in ResourceManagerImpl)

Alessandro -
Is there a place where we can see what you have thus far (github
perhaps?), perhaps others could help as well.

Its not that hard to support CIFS as secondary storage with limitations.
Just the way there is no native support for Hyper-V/Windows server to use
NFS shared storage, I doubt if there is support for CIFS across the
hypervisors (Xen, vSphere, Kvm, Ovm) that CloudStack supports today. So
multi-hypervisor CloudStack deployment with CIFS as only secondary storage
does not work. If we impose, in order to use CIFS as secondary storage a
zone should only have Hyper-v hypervisors in the deployment then this may
not be issue. Alternatively in multi-hypervisor deployment one could add
both NFS and CIFS secondary storage, and tweak CloudStack
planner/allocators so that a VM created from template on CIFS storage is
launched only on Hyper-V hosts.
Please note that SSVM (secondary storage VM) also works with NFS secondary
storages only. In order to make SSVM handle CIFS, you can introduce a new
SecondaryStorageResource implementation for CIFS and change the way share
is mounted in SSVM. Most of the helper scripts and implemented
functionality on NfsSecondaryStorageResource should work.

Hi guys,
we have some trouble with NFS to access the secondary storage as we are targetting Hyper-V server which, unlike Windows Server, doesn't have a native NFS client.
How hard do you guys think it would be to add CIFS as an alternative to NFS in CloudStack?
Thanks!

Hi Alessandro:
I just wanted to check and see how things were going and what kind of
progress you were making. Is there anything we can help you with?

Hi Rajesh,
here's the error. It happens when we try to add a template. We need to find a way to replace this with a dummy implementation.
[java] WARN [storage.download.DownloadMonitorImpl] (http-8080-5:) There is no secondary storage VM for secondary storage host nfs://10.73.76.36/export/secondary
The fake secondary storage VM exists and is shown as in "Running" state in the admin panel.
Thanks!
Alessandro
