Add support for Volume Shadow Copy Service Guest Quiesce for application-level consistency. The RHEV Backup and Restore API will provide integration with Microsoft Windows Volume Shadow Copy Service (VSS) using qeum-ga. The VSS provider registration will be made in the guest level as part of the Guest Tools deployment.
Basically everything should be there (we deploy qemu-ga which provides vss support and live snapshot automatically tries to quiesce whenever possible).
Can be tested using vshadow tool part of the following SDK: http://www.microsoft.com/en-us/download/details.aspx?id=23490 See usage: http://msdn.microsoft.com/en-us/library/windows/desktop/bb530725%28v=vs.85%29.aspx
I'm using RHEV3.3 (IS25) and I've installed its rhev-guest-tools on a windows VM (RHEV-toolsSetup_3.3_6.iso on windows server 2008). The rhev-guest-tools ISO contains qemu-guest-agent but VSS for windows is not supported.
This bug can't be added to the 3.3.2 errata due to a missing acks. - Kiril
Sean, please check my comment #15
vshadow creation succeeded: Reproduction steps: 1. installed a windows VM with 2 disks and rhevm-guest-tools with the mentioned qemu-guest-agent version which support vss for windows. 2. installed Volume Shadow Copy Service SDK 7.2 on the guest. 3. created vshadow using VSS SDK Querying all shadow copies with the SnapshotSetID {1aba6254-ef36-4297-94da-72b4c d15a886} ... * SNAPSHOT ID = {2a41a81c-1978-47b7-a551-773fec0beaad} ... - Shadow copy Set: {1aba6254-ef36-4297-94da-72b4cd15a886} - Original count of shadow copies = 1 - Original Volume name: \\?\Volume{8e3996cf-b534-11e3-89fe-001a4afb125c}\ [E: \] - Creation Time: 3/26/2014 3:29:12 PM - Shadow copy device name: \\?\GLOBALROOT\Device\HarddiskVolumeShadowCopy1 - Originating machine: WIN-12DQ34BZQBR - Service machine: WIN-12DQ34BZQBR - Not Exposed - Provider id: {b5946137-7b9f-4925-af80-51abd60b20d5} - Attributes: Auto_Release Differential - Mark all writers as succesfully backed up...
