Overview
Target
- Hyper-V Server 2012
- WMI for VMM control
Strategy
- CloudStack Agent Model
- Business logic in ServerResource accesses WMI
Support basic commands
- VM lifecycle
- Local disk creation from template
- VM creation, start/stop, and destruction
- VMM monitoring
- Host, VM and storage stats returned to CloudStack Server
VM network isolation using VLANs
Basic template management
Expand networking support
- Flat networking with Security Groups for VM isolation
Volume service
- Volumes management independent of VMs
Expand VM management
Shared storage
Native SystemVMs
- Console access
- RDP sessions to Hyper-V VMs
Progress
HyperV Branch https://git-wip-us.apache.org/repos/asf?p=cloudstack.git;a=shortlog;h=refs/heads/hyperv
- Plugin is cloud-plugin-hypervisor-hyperv, under ./plugins/hypervisor/hyperv
- Minor changes to UI required for template creation
The changes are being committed in https://git-wip-us.apache.org/repos/asf/cloudstack/repo?p=cloudstack.git;a=tree;h=hyperv;hb=hyperv hyperv branch.
- . Pure hyperv zone will be supported. No mixed zone.
- . Support for SMB/CIFS as primary and secondary.
- . Local storage as primary
- . Start/Stop instance.
- . Reboot and destroy instance.
- . Attach/ Detach iso.
- . Template and iso registration.
- . Attach and Detach volumes.
- . Live migration of an instance from one host to another. Only vm migration (no storage migration).
- . Advanced networking. Isolation using vlans.
- . Isolated and shared networking.
- . Console access.
Architecture
- Reuse KVM-style Agent Container
- Java-based agent executes on hypervisor
- Call out to WMI via Hyper-V scripts
- Use existing SystemVMs
- Include XenServer cluster to run SSVM and Virtual Router
- Local Primary Storage
- Secondary storage accessed as NFS/SMB via Windows Server 2012
- Free license Hyper-V Server 2012 has no NFS client
- Admin manually mounts secondary storage to appear as local folder
- Executes in Cygwin
Design changes
Near
Adopt Javelin Storage model
Far
V2 WMI API
- Currently mix of v1 and v2
Access WMI from Java
- Remove use of scripts
- Remove agent from Hyper-V server
Misc Design Notes
Local Storage
- UUIDs for volumes correspond to their file names on disk. Only this UUID is persisted on the Hyper-V Server
Misc QA Notes
Test Plan
Unit tests
- Each test corresponds to one or more Command objects sent to a ServerResource
- No unit tests for server-side objects (Discoverer or HypervisorGuru)
- Tests written to work only on Hyper-V 2012
