Unlike the host devices of other types, SCSI host device XML supports "shareable" tag. This patch introduces it for the virSCSIDevice struct for a later patch use (to detect if the SCSI device is shareable when preparing the SCSI host device in QEMU driver). --- src/libvirt_private.syms | 1 + src/qemu/qemu_cgroup.c | 3 ++- src/qemu/qemu_hostdev.c | 9 ++++++--- src/security/security_apparmor.c | 3 ++- src/security/security_dac.c | 6 ++++-- src/security/security_selinux.c | 6 ++++-- src/util/virscsi.c | 11 ++++++++++- src/util/virscsi.h | 4 +++- 8 files changed, 32 insertions(+), 11 deletions(-)
