无法使用 nvidia 从 lxc 容器内部运行 glxdemo

我已经创建了lxc包含许多软件包的自定义工具链容器。与图形相关，我已nvidia 367.27使用此容器内的 nvidia 安装程序安装了驱动程序（称为mk7icontainer）

nvidia 驱动程序库/二进制文件安装在/usr/share/nvidia该容器内的路径上。

我也在容器内的mesa路径中安装了。/usr

我glxdemo使用以下命令编译了源代码：

gcc -g glxdemo.c -Wl,--rpath-link,/usr/share/nvidia/lib -Wl,-rpath,/usr/share/nvidia/lib \
-Wl,--rpath-link,/usr/share/nvidia/lib/tls -Wl,-rpath,/usr/share/nvidia/lib/tls \
-Wl,--rpath-link,/usr/share/nvidia/lib/vdpau  -Wl,-rpath,/usr/share/nvidia/lib/vdpau \
-Wl,--rpath-link,/usr/share/nvidia/lib/xorg/modules -Wl,-rpath,/usr/share/nvidia/lib/xorg/modules \
-Wl,--rpath-link,/usr/share/nvidia/lib/xorg/modules/drivers -Wl,-rpath,/usr/share/nvidia/lib/xorg/modules/drivers \
-Wl,--rpath-link,/usr/share/nvidia/lib/xorg/modules/extensions -Wl,-rpath,/usr/share/nvidia/lib/xorg/modules/extensions -lX11 -lGL -lGLU -lglut -lm -o glxdemo

在容器里面，我有

DISPLAY=":0"
XAUTHORITY=/root/.Xauthority

我正在bash使用以下命令在容器中启动：

sudo lxc-attach -n mk7icontainer --clear-env  -- /usr/bin/bash

我的主机正在运行Ubuntu 16.0.4，我nvidia 367.27使用其安装程序安装了相同的驱动程序。它运行良好。我甚至可以glxdemo在主机上运行而没有任何问题。

但是，当我尝试glxdemo在容器内运行（使用上面提到的命令编译）时，出现以下错误：

X Error of failed request:  BadValue (integer parameter out of range for operation)
Major opcode of failed request:  154 (GLX)
Minor opcode of failed request:  3 (X_GLXCreateContext)
Value in failed request:  0x0
Serial number of failed request:  24
Current serial number in output stream:  25

有人知道这里出了什么问题吗？

我也想知道如何读取这些错误以缩小问题范围。

源代码为glxdemo：

      exit(1);
   }

        printf("\n glXCreateContext successfull \n");

   glXMakeCurrent( dpy, win, ctx );

   return win;
}

            break;
         case ConfigureNotify:
            resize( event.xconfigure.width, event.xconfigure.height );
            break;

   }
}

int main( int argc, char *argv[] )

   Window win;

   dpy = XOpenDisplay(NULL);
        if(!dpy)
        {
                printf("\nError in XOpenDisplay\n");
        }
        printf("\nXOpenDisplay successfull\n");

   win = make_rgb_db_window( dpy, 300, 300 );

   printf("\nmake_rgb_db_window successfull \n");
   glShadeModel( GL_FLAT );
   glClearColor( 0.5, 0.5, 0.5, 1.0 );

   XMapWindow( dpy, win );

   event_loop( dpy );
   return 0;
}

答案1

我能够解决这个问题。

我必须nvidia在配置文件中添加设备节点lxc container。

lxc.cgroup.devices.allow = c 195:* rwm
lxc.mount.entry = /dev/nvidia0 dev/nvidia0 none bind,optional,create=file
lxc.mount.entry = /dev/nvidiactl dev/nvidiactl none bind,optional,create=file
lxc.mount.entry = /dev/nvidia-modeset dev/nvidia-modeset none bind,optional,create=file
