If block job is completed with error qemu additionally provides error message. This patch introduces new event VIR_DOMAIN_EVENT_ID_BLOCK_JOB_ERROR to pass error message to client. This error message has no semantics and should not be interpreted. API and RPC layer also have reserved 'code' field to pass semantics loaded error code value in the future. Signed-off-by: Nikolay Shirokovskiy <nshirokovskiy@xxxxxxxxxxxxx> --- Diff from v1 [1]: - replace block job event version 3 with block job error event - add code field to API/RPC to pass error code in the future Peter, I decided not to use enum/union as this looks like to much effort to extend code generation for this simple case. Using typed params looks unsuitable too.
