From: Namhyung Kim <namhyung at gmail.com> Add virtio pstore device to allow kernel log files saved on the host. It will save the log files on the directory given by pstore device option. $ qemu-system-x86_64 -device virtio-pstore,directory=dir-xx ... (guest) # echo c > /proc/sysrq-trigger $ ls dir-xx dmesg-0.enc.z dmesg-1.enc.z The log files are usually compressed using

The virtio pstore driver provides interface to the pstore subsystem so that the guest kernel's log/dump message can be saved on the host machine. Users can access the log file directly on the host, or on the guest at the next boot using pstore filesystem. It currently deals with kernel log (printk) buffer only, but we can extend it to have other information (like ftrace dump) later. It
