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。

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
