[libvirt] [PATCH] qemu: add tun devices to cgroup ACL

From: Roy Li <rongqing.li(a)windriver.com&gt; When systemd is used as init, CGroup will be enabled by default, and lead to virsh unable to start VM(which is using the tun/tap), since virsh can not access /dev/net/tun device Signed-off-by: Roy Li <rongqing.li(a)windriver.com&gt; --- src/qemu/qemu.conf | 3 ++- src/qemu/qemu_cgroup.c | 2 +- src/qemu/test_libvirtd_qemu.aug.in | 1 + 3 files changed, 4 insertions(+), 2 deletions(-) diff --git a/src/qemu/qemu.conf b/src/qemu/qemu.conf index c6db568..225cd0f 100644 --- a/src/qemu/qemu.conf +++ b/src/qemu/qemu.conf @@ -272,7 +272,8 @@ # "/dev/null", "/dev/full", "/dev/zero", # "/dev/random", "/dev/urandom", # "/dev/ptmx", "/dev/kvm", "/dev/kqemu", -# "/dev/rtc","/dev/hpet", "/dev/vfio/vfio" +# "/dev/rtc","/dev/hpet", "/dev/vfio/vfio", +# "/dev/net/tun" #] # # RDMA migration requires the following extra files to be added to the list: diff --git a/src/qemu/qemu_cgroup.c b/src/qemu/qemu_cgroup.c index 0e94cae..7c15c07 100644 --- a/src/qemu/qemu_cgroup.c +++ b/src/qemu/qemu_cgroup.c @@ -45,7 +45,7 @@ static const char *const defaultDeviceACL[] = { "/dev/random", "/dev/urandom", "/dev/ptmx", "/dev/kvm", "/dev/kqemu", "/dev/rtc", "/dev/hpet", "/dev/vfio/vfio", - NULL, + "/dev/net/tun", NULL, }; #define DEVICE_PTY_MAJOR 136 #define DEVICE_SND_MAJOR 116 diff --git a/src/qemu/test_libvirtd_qemu.aug.in b/src/qemu/test_libvirtd_qemu.aug.in index 30fd27e..2ab7a8d 100644 --- a/src/qemu/test_libvirtd_qemu.aug.in +++ b/src/qemu/test_libvirtd_qemu.aug.in @@ -48,6 +48,7 @@ module Test_libvirtd_qemu = { "9" = "/dev/rtc" } { "10" = "/dev/hpet" } { "11" = "/dev/vfio/vfio" } + { "12" = "/dev/net/tun" } } { "save_image_format" = "raw" } { "dump_image_format" = "raw" } -- 2.1.0
