2018-02-09Use #include "..." for our own headers, <...> for othersMarkus Armbruster1-2/+2
System headers should be included with <...>, our own headers with "...". Offenders tracked down with an ugly, brittle and probably buggy Perl script. Previous iteration was commit a9c94277f0. Delete inclusions of "string.h" and "strings.h" instead of fixing them to <string.h> and <strings.h>, because we always include these via osdep.h. Put the cleaned up system header includes first. While there, separate #include from file comment with exactly one blank line.

2017-10-10vhost-user-scsi: use glib loggingMarc-André Lureau1-56/+21
- PLOG is unused - code is compiled out unless debug is enabled - logging is too verbose - you can pipe to ts to have timestamp if needed, or use structured logging with more recent glib Signed-off-by: Marc-André Lureau <marcandre.lureau@redhat.com> Reviewed-by: Philippe Mathieu-Daudé <f4bug@amsat.org>

2017-06-15vhost-user-scsi: Introduce a vhost-user-scsi sample applicationFelipe Franciosi2-0/+887
This commit introduces a vhost-user-scsi backend sample application. It must be linked with libiscsi and libvhost-user. To use it, compile with: $ make vhost-user-scsi And run as follows: $ ./vhost-user-scsi -u vus.sock -i iscsi://uri_to_target/ $ qemu-system-x86_64 --enable-kvm -m 512 \ -object memory-backend-file,id=mem,size=512m,share=on,mem-path=guestmem \ -numa node,memdev=mem \ -chardev socket,id=vhost-user-scsi,path=vus.sock \ -device vhost-user-scsi-pci,chardev=vhost-user-scsi \ The application is currently limited at one LUN only and it processes requests synchronously (therefore only achieving QD1). The purpose of the code is to show how a backend can be implemented and to test the vhost-user-scsi Qemu implementation. If a different instance of this vhost-user-scsi application is executed at a remote host, a VM can be live migrated to such a host.
