[PATCH v2 11/13] qemu: convert process stop/attach to use qemuDomainLogContextPtr

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

 



When the qemuProcessAttach/Stop methods write a marker into
the log file, they can use qemuDomainLogContextWrite to
write a formatted message.
