Re: [libvirt] [PATCH v3 1/5] virDomainGetDiskErrors public API

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. --- include/libvirt/libvirt.h.in | 32 ++++++++++++++++++++ python/generator.py | 3 +- src/driver.h | 7 ++++ src/libvirt.c | 65 ++++++++++++++++++++++++++++++++++++++++++ src/libvirt_public.syms | 1 + 5 files changed, 107 insertions(+), 1 deletions(-)

+ * + * Since calling virDomainGetDiskErrors(dom, NULL, 0, 0) to get preferred size + * of @errors array and getting the errors are two separate operations, new + * disks may be hotplugged to the domain and new errors may be encountered + * between the two calls. Thus, this function may not return all disk errors + * because the supplied array is not large enough. Such errors may, however, + * be detected by listening to domain events.
