1. Overview

Hotfix 12 for Virtuozzo Automator 7.0.2 provides a new feature as well as stability and usability fixes.

2. New Features

  • Ability to switch between coalescing and rotational backup schemes. In the former case, the set number of incremental backups will be maintained indefinitely, the oldest one being merged when a new one is created. In the latter case, a new full backup will be created after the maximum number of incremental backups is reached. The new setting has been added to the Setup > Configure Backups screen. For more information, see “Defining Global Backup Settings” in the Administrator’s Guide. (PVA-37624)

3. Bug Fixes

  • Changing VM’s OS distribution via API calls could reset the ‘cpu_limit’ and ‘iolimit’ values. (PVA-37513)

  • Backup configuration was not respected by Virtuozzo 6 containers migrated to Virtuozzo Hybrid Server 7. (PVA-37526)

  • VA Agent could report zero I/O statistics for nodes, preventing iostat from being used for I/O accounting. (PVA-37539)

  • Scheduled tasks could ignore the “Number of full backups to keep” parameter. (PVA-37544)

  • VA Agent could return non-zero ‘counter_memory_used’ values for stopped VMs. (PVA-37547)

  • Used memory stats could be reported for suspended VMs. (PVA-37548)

  • Other fixes. (PVA-34133, PVA-37305, PVA-37514, PVA-37516, PVA-37517, PVA-37518, PVA-37535, PVA-37538, PVA-37540, PVA-37543, PVA-37551, PVA-37552, PVA-37562, PVA-37563)
