Fixes and Improvements

These updates contain fixes for the following issues:

• In rare conditions, the QEMU Storage I/O processor used by the GFS2 and XFS Storage Repository types can crash as the associated virtual machine transitions from emulated to paravirtual storage. This crash causes the virtual machine to lose access to its virtual disks and fail to boot.
• When creating an iSCSI SR by using xsconsole, xsconsole displays a “timed out” error message even when the SR is created successfully.
• The HTTPS is used unnecessarily in localhost VM migration.
• Distributed tracing: An issue in instrument which would cause errors like “load() missing 1 required positional argument: ‘sr_uuid’”.
• A performance issue in intel-i40e.
• When requesting bug-report archives, tapdisk logs are not included in the full bug-report archive.
• When requesting bug-report archives, collected kernel module infos are not complete in rare cases.

These updates include the following improvements:

• Remove deprecated iovirt plugin from the toolstack.
• Improvements to distributed tracing.
• Add new SR status “Unreachable” and “Unavailable”. They were mapped to “Recovering” before.
