This would be a _VERY_ > useful feature. Hi, AFAIK nobody is working on it. A year ago there was newer release of the patch against CURRENT at that time (FreeBSD 7) [1] http://www.ualberta.ca/~cdjones/jail-cpumem-current.tgz I never test this patch on current, only version for 6.x and if patch for current were made without improvements, it contains same bugs as patch for 6.x (eg.: not showing memory usage). There are some other guys trying to do the same, but I never saw patches published. Andrew Snow - Jails as a VPS [2] Alex Lyashkov - Jail2 aka FreeVPS [3a][3b] Or fixes for C.D. Jones work: Chris Thunes - jtune not showing resource usage - fixed [4] (note - attached patch is reversed) [5] So as you can see, there were some talks about Jail improvements for one year existence of this mailinglist (freebsd-jail@freebsd.org), also it is two years from SoC [6] and we still don't have anything commited to 7.x or to CURRENT. It is sad. There is little attention to jails, only few people are able to do some coding work etc. If the are somebody with skills and time to resurrect some mentioned projects, I am willing to help with testing. Also it will be good to have some up-to-date wiki page with "all the patches" (resource limits, SysV IPC, multiple IPs...) and status of this work, so people can easily find and try it.
