Hello everyone, <br><br>I am new to OpenVZ and so far I have liked it a lot. The Quick installation guide is extremely useful. I am trying to run a thermal emulation model inside a container. I have installed all the necessary packages, However, When I run the thermal emulation software which basically collects the power consumed by the components(cpu,network,disk) of the machine, I get a segmentation fault. When I run the same in the host node, I don't get any error and the software runs smoothly. <br>
<br>For the thermal emulation model I need to set the /dev/sda properly. However when I tried to run /dev from the container I could not get sda or hda but rather found "pts". what does that mean?<br><br><br>From inside the container :<br>
<br>[root@rajeshr-linux bin]# ./monitord -p 8367 -s localhost -d -v<br>Just defined sockaddr->sin_addr.in_addr=(100007f)<br>Segmentation fault<br><br>Is it because the container is not given access to the power modules in the host node? I have mounted three of the folders from the host node to the container using the command <br>
<br>mount --bind /root/Desktop/Mercury /vz/root/101/Mercury<br><br>I tried to see if the container has access and here is what I found.<br><br><b>Container:</b><br>[root@rajeshr-linux bin]# mount<br>/dev/simfs on / type simfs (rw)<br>
