[libvirt] [PATCH 0/4] Add virDomainIOError API
by Jiri Denemark
We already provide ways to detect when a domain has been paused as a
result of I/O error, but there was no way of getting the exact error or
even the device that experienced it. This new API may be used for both.
Jiri Denemark (4):
virDomainIOError public API and remote protocol
virsh: Implement domioerror command
qemu: Refactor qemuMonitorGetBlockInfo
qemu: Implement virDomainIOError

[libvirt] [PATCH] hash: minor touchups
by Eric Blake
On RHEL5, I got:
util/virrandom.c:66: warning: nested extern declaration of '_gl_verify_function66' [-Wnested-externs]
The fix is to hoist the verify earlier. Also some other hodge-podge
fixes I noticed while reviewing Dan's recent series.
* .gitignore: Ignore new test.
* src/util/cgroup.c: Bump copyright year.
* src/util/virhash.c: Fix typo in description.
* src/util/virrandom.c (virRandomBits): Mark doc comment, and
hoist assert to silence older gcc.
---
Pushing under the build-breaker rule.
We didn't notice it earlier because newer gcc introduced
_Static_assert (per C11), so that verify() doesn't have to
rely on extern declarations in that case.
