OpenVZ

XEN tehnoloogia pole alati sobiv eriti kui pole soovi kasutada erinevaid operatsoonisüstemee vaid sama os põhiseid eraldatud masinaid. OpenVZ ideaalne lahendus.

In order for VE to work, some nodes should be present in VE's /dev. For modern distributions, udev is taking care of it. For a variety of reasons udev doesn't make much sense in a VE, so the best thing to do is to disable udev and create needed device nodes manually.

Note that in some distributions /dev is mounted on tmpfs — this will not work in case of static /dev. So what you need to do is find out where /dev is being mounted on tmpfs and remove this. This is highly distribution-dependent; please add info for your distro here.

nano /etc/conf.d/rc
RC_DEVICES="static"
