New maintenance update candidates for XCP-ng 8.3 LTS
This batch of updates contains performance improvements, fixes, a guest tools update, and other improvements.
What changed
Virtualization & System
kernel: Fix potential deadlocks in the NFS subsystem.
xen:
Enable Viridian enlightenments to prepare for support of Windows VMs with >64 vCPUs
Sync with XenServer release 4.17.7-2. It fixes XSA-511, which didn't affect XCP-ng.
systemd: Fix detection of NVMe controllers with multiple namespaces
Control Plane
xapi:
Improve RPU stability by only migrating VMs to already-updated hosts
Improve VDI migration performance by pipelining NBD writes
guest-templates-json:
Sync with XenServer's guest-templates-json-2.0.16-1. It removes the Kylin Linux 7 Guest template.
Disable Viridian in the "Other install media" template by default. As a reminder, Windows VMs must use Windows templates.
Storage
blktap:
A fix for a tapdisk crash happening when tapdisk pauses a VDI when a coalesce is in progress. This issue was caused by a use-after-free bug. We took time to thoroughly audit the code around pause/commit/cancel operations, and thus robustify the pause and commit code in this release.
Customers could get tapdisk with infinite stalled IO on QCOW2 VDI. A race-condition was identified that could allow to miss a notification from the front-end and therefore never check the blkif ring for new requests.
On a tapdisk running on a supporter node, CBT metadata does not flush before a pause operation. During the pause operation, the master host modifies the CBT metadata, then after the unpause the old metadata are flushed and discard master's modifications. Finally the CBT logs are detected as inconsistent and discarded.
Grow up the QCOW2 metadata cache to help on big disks.
sm:
Robustify iSCSI calls against race condition and bad access using lock context manager.
Retry host key tag removal when XAPI is unreachable or restarted to prevent errors and finish action.
Explicitly notify a missing LINSTOR resource definition instead of displaying a human-unreadable trace.
Repair LINSTOR RAW volume creation. Regression caused by QCOW2 code refactoring.
Fix LINSTOR SR creation when a VG is missing on a host. Changes in behavior brought by an update of LINSTOR RPMs broke this feature, which prevented the creation of an SR in this situation. We're expanding the test suite to prevent this in the future.
To help recovering from an eventual LINSTOR database corruption, it's now backed up regularly and after every major operation, locally on the master, and on the DRBD LINSTOR database volume.
Fixed an issue on shared LVM-based SR (LVMoISCSI, LVMoHBA) where a failed live leaf coalesce of a QCOW2 image on a slave host caused the SRs to remain in an SR_FAILURE_1200 error state until the VM using the VDI was stopped or tapdisk was manually paused.
Reduce qemu-img log verbosity in SMlog.
Fix LVM metadata corruption on slave when CBT log deletion is triggered on VDI activation.
Prevent an incorrect online coalesce to be reported as successful and causing issues with the QCOW2 chain.
Add QCOW2 support during interrupted leaf-coalesce operations on file-based SRs.
Network
openvswitch: The openvswitch package no longer installs the unused openvswitch-cfg-update XAPI plugin file, which has been superseded by openvswitch-config-update from xapi-core. This is only meant to avoid confusion and brings no functional change.
UI
xo-lite:
[Treeview] Add VM tree actions (PR #10304)
[Pool/networks] Add the possibility to create new network or bonded network (PR #10145)
[VM] Add VDIs page with table and side panel (PR #10269)
[Host/Network] Add ability to rescan physical network interfaces (PIFs) (PR #10147)
Fix inconsistent spacing in side panel cards (PR #10279)
Fix missing collapse buttons on pools and hosts in the tree sidebar (added hasChildren prop) (PR #10244)
[Pool/networks] Add the possibility to create new internal network (PR #10235)
Drivers and Middleware
vendor-drivers: The out of tree microsemi-aacraid driver from the RPM has proven to be unreliable. It has several issues, is missing patches from upstream and hasn't been updated for a while. So, we switch back to the in-tree driver just like XCP-ng 8.2 was doing.
xcp-ng-pv-tools:
Update to XCP-ng Windows Guest Tools 9.2.385.
Include the XenTools-fix-9.2.351.msp hotfix tool for users running 9.2.350.
