I have fedora 14 installed and wish to use/learn kvm. I installed via groupinstall the virtualization group. I see vmx in /proc/cpuinfo. but when I start virt-manager I get a message that kvm is not installed or cannot be leaded into the kernel (to make a long message short). I am at a loss here as to what to do. I run cat /proc/modules and see "kvm 257420 0 - Live 0xffffffffa022a000". also after running modprobe kvm I run [root@fed14 ~]# lsmod | grep -i kvmkvm 257420 0 and see kvm there.

Trying to change permissions on a file in /proc/sys/fs/inotify. The command syntax are:
Code:
sudo chmod u+w max_user_watches
and the result is:
Code:
chmod: changing permissions of `max_user_watches': Operation not permitted Also tried to change it when logged in as root, same results. Parent directory permissions are dr-xr-xr-x, and are the same up the chain. Tried to change the directory permissions to u+w, that didn't work either. FWIW, /proc is part of the / partition, and it has ~600MB free space.
I am trying to read the /proc/net/tcp6 file of a huge server (chat server) for monitoring the tcp6 connection states.
My server's tcp6 file has more than 26000 lines. For monitoring the server connections, my monitoring tool has to read the /proc/net/tcp6 file quickly in a regular interval (5 secs) and process. Presently it takes minimum 6-7 seconds for reading the whole file.
My tool can able to read the normal file (26,000 lines) less than 1 second, but it is not possible to read the same size of proc file.
I have 2 questions:
1) Why proc file takes more read time than normal file?
2) Is there any way to read the /proc/net/tcp6 file more quickly?
I am using RedHat MRG on a standalone intel PC that has 8 cpus. It has 2 Quad cores. I am trying to force some specific persistent tuning on it so that the OS and IRQs are all on one CPU socket and then I can run my Application on the other CPU socket (4 CPUs) using the taskset command.
I have been reading up on this mainly at [url] and having some success. But, I have one IRQ that is not active until my application runs that I want to force it to be on CPU 4.
And so I believe I can do this by setting /proc/irq/default_smp_affinity to 10. But, I do not have such a file on my system. How can I create this file at boot time properly?

But still /proc/devices is not created. What am I doing wrong?init script for that initrd.img:

To get the kernel messages of new java process, i refer the details from /proc/<java pid>/stat and /proc/<java pid>/statm files. For some java processes, I didn't find any details in the /proc/<java pid>/statm file. It has only 7 number of 0s. But /proc/<java pid>/stat file has the details. And also this kind of process will have the life time of nearly 1 minute.
Kernel version using: Linux-2.6.18-8.1.8.el5 Is there any possibility of java process without the memory details in the /proc/<java pid>/statm file? If it is possible, how to know the memory related details of that processes?
I have to get soem statistic about interfaces from /proc/net/dev. but statistic on this file is reset when get reach more than 4G byte.I think linux has limitation on this case.
