[PATCH 1/4] qemu: Introduce qemuDomainAgentJob

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



This enum will list all possible jobs for guest agent. The idea
is when a thread needs to talk to guest agent only it will take
the QEMU_AGENT_JOB instead of QEMU_JOB helping better
concurrency.
