Hello everyone, 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.
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? >From inside the container : [r...@rajeshr-linux bin]# ./monitord -p 8367 -s localhost -d -v Just defined sockaddr->sin_addr.in_addr=(100007f) Segmentation fault 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 mount --bind /root/Desktop/Mercury /vz/root/101/Mercury I tried to see if the container has access and here is what I found. *Container:* [r...@rajeshr-linux bin]# mount /dev/simfs on / type simfs (rw) /proc on /proc type proc (rw) /sys on /sys type sysfs (rw) none on /dev/pts type devpts (rw) none on /proc/sys/fs/binfmt_misc type binfmt_misc (rw) /dev/root on /home type ext3 (rw,data=ordered) /dev/root on /mercury type ext3 (rw,data=ordered) /dev/root on /periva type ext3 (rw,data=ordered) /dev/root on /root type ext3 (rw,data=ordered) What does data=ordered mean here?
