When creating ostemplate, it always creates an temporary container to download and install packages. But vzctl can't open ve.state with O_WRONLY, result is EACCES ( Permission denied). cmd: vzpkg create cache centos-6-x86_64, full log is in the attachment I found an issue on bugs.openvz.org<http://bugs.openvz.org> (https://bugs.openvz.org/browse/OVZ-6304), I wonder why it was treated as "Feature Request" and a "Userspace" problem. On the same time, everything works fine in the cloudlinux, they have nearly the same environment kernel 3.10.0-123.1.2.vz7.5.29 vzctl v.7.0.60-1.vz7 libvzctl-7.0.89-1.1.vz7.x86_64 vztt-7.0.22-1.vz7.x86_64 -------------- next part -------------- An HTML attachment was scrubbed...
