New maintenance update candidates for XCP-ng 8.3 LTS
This batch of updates focuses on storage bug fixes and performance improvements.
What changed
Storage
blktap:
When CBT is enabled, an issue occurred where tapdisk opened cbtlog instead of the primary QCOW2 image. This previously caused commit operations (ENOTSUPP) and leaf-coalesce routines to fail, resulting in excessive storage consumption on the SR. Tapdisk now correctly bypasses the cbtlog image to allow proper coalescing.
sm: Fix a bug where the coalesce on a secondary host of a QCOW2 VDI on LVMSR could corrupt LVM metadata and would need manual intervention to restore them.
xapi:
- Migration speeds are now improved for sparse QCOW2-backed VDIs, as empty sectors are no longer transferred.
- Preserve VDI tags on migration. This is a foundational fix for kubernetes integration.
Versions
blktap: 3.55.5-9.3.xcpng8.3 -> 3.55.5-9.4.xcpng8.3
sm: 3.2.12-23.4.xcpng8.3 -> 3.2.12-23.5.xcpng8.3
xapi: 26.1.16-1.1.xcpng8.3 -> 26.1.16-1.2.xcpng8.3
