Hi Folks! some people asked me about the 'advanced' features FreeVPS provides over the Linux-Vserver patches ...
so here is the 'list' provided at the FreeVPS site http://www.freevps.com/docs/faq.html#General3 and my comments/questions to that ... > FreeVPS extends the original Linux VServer functionality. > FreeVPS implementation include FreeVPS kernel patch and FreeVPS > tools. Together they add the following new features to VPS: > * Limits on: > - total memory usage > - resident memory size in Linux-VServer, VM is accounted and enforced, RSS only accounted, I don't know what 'total memory usage' means ... > - number of processes is accounted and enforced, as all limits, can be changed at runtime > - disk usage quota this is handled by the Quota Disk Limit (included in the quota patch) > - file handles > - tcp sockets both are not accounted yet, and not limited. > * Advanced context management: > - create/destroy a context > - enter a context well, that is basic functionality ... > - running status vserver-stat and /proc/virtual provide this ... > - enable/disable creating new processes in a context > - send signal to all processes in context this is done with the vkill command (via syscall since 1.1.6) > * inodes attributes management: > - context tag xid tagging is used by Quota Disk Limits and Per Context Quota and it comes in 3 flavours (UID32/GID16, UID24/GID24 and UID32/GID32) > - flag for files shared between contexts don't know what this is, but might be the IUNLINK flag > - immutable flag well if that is what it says, then it's basic linux stuff --- so after this shoot out ;) the following differences seem to remain: > * Limits on: > - resident memory size > - file handles > - tcp sockets > * Advanced context management: > - enable/disable creating new processes in a context and I don't know the FreeVPS status of the following Linux-VServer features: - vroot device (security) - Token Bucket scheduler stuff (Sam) - uts_name modifications (stealth) - procfs security - uptime virtualization - reboot userspace helper best, Herbert _______________________________________________ Vserver mailing list [EMAIL PROTECTED] http://list.linux-vserver.org/mailman/listinfo/vserver
