Hi List, I am looking for an option for sshd to start user's shell (when logging in interactively to a remote host) in a control group via cgexec - so for example: /bin/cgexec -g <username> /bin/bash This would be extremely handy on linux Terminal servers to control users access to the system resources (protect system from a malicious user hogging the machine by running cpu/memory intensive applications). Is something like that po...

...; <weight>1000</weight> </blkiotune> VM2 (background): <cputune> <shares>2</shares> </cputune> <blkiotune> <weight>100</weight> </blkiotune> I've tested write throughput on the host using cgexec and dd, demonstrating that libvirt has correctly set up the cgroups: cgexec -g blkio:libvirt/qemu/foreground time dd if=/dev/zero of=trash1.img oflag=direct bs=1M count=4096 & cgexec -g blkio:libvirt/qemu/background time dd if=/dev/zero of=trash2.img oflag=direct bs=1M count=4096 &...

...14 kernel if it is good enough for cgroup usage because I am trying to set a cgroup under cpu subsytem ( /dev/cgroup/cpu/group1/ ) that have /cpu.rt_runtime_us of 100000 while cpu.rt_period_us has a value of 1000000 i.e a ratio of 1/10 . still when I run a task (endless loop) in that group (cgexec -g cpu,cpuset:group1 ./test) it gets all the cpu core time that is assigned to it ( i watch via top utility) , so it seems that the quota set via the group does not take effect although I restart the cgconfig service . I also verified libcgroup is installed by: rpm -q libcgroup Am I missing...

...extra stat information and optionally a file checksum. The output is designed to be easily grepped to look for common patterns. For example, to display all setuid and setgid executables in a virtual machine you can do: # virt-ls -lR -d guest / | grep '^- [42]' - 4755 12544 /bin/cgexec - - 4755 32448 /bin/fusermount - - 4755 78648 /bin/mount - - 4755 43160 /bin/ping - - 4755 47888 /bin/ping6 - - 4755 34904 /bin/su - - 4755 50432 /bin/umount - [etc] To display all public writable directories: # virt-ls -lR -d guest / | grep '^d ....

Hi, Is there some tool or method in centos that can limit cpu usage to some percentage for specified processes that consume large cpu resource? I found cpulimit which is only able to limit one process. what I want is one tool that can limit several same processes' cpu usage. Thanks! Regards andrew
