Perf KVM tool installation in Ubuntu
Hi,
I am using Ubuntu 14.04 version & I wanted to install perf-kvm tool to profile my KVM guest performance. When I try to install the tool with the following command
apt-get install linux-tools-
I was getting the error
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
Can you please help me installing this or Is there any other tool available to profile the guest for Ubuntu
Thanks

You seem to be running outdated versions of the kernel packages, and you have a multitude of kernel meta packages installed.
1. You should make up your mind what kernel series you want to run
- standard trusty (3.13)
- lts-utopic (3.16)
- lts-vivid (3.19)
- lts-wily (4.2)
2. for each of these kernel families you seem not to have the newest version installed, because you apparently did not download and install the newest updates.
What is the output of the commands
sudo apt-get update
apt-get --simulate dist-upgrade

Apparently you have broken dependencies in the installed packages.
Try

The output of the simulation shows that there are conflicts between the different versions of the packages.
You have to make up your mind what kernel series you want to run
- standard trusty (3.13)
- lts-utopic (3.16)
- lts-vivid (3.19)
- lts-wily (4.2)
Based on that decision, all other versions should then be removed, and the selected one can then completely be installed.

How can we remove the kernel?
Say, I decided to keep the Its-Wily(4.2) version & remove rest, How can I
do that?
Thanks so much for the help.:)

"...How can we remove the kernel?"
You can remove a specific kernel version with the package management programs, e.g. using the command "sudo apt-get remove --purge <package_name>". You just have to make sure that you leave a working version of the kernel installed, or you will run into problems with the next reboot.
For listing all kernel packages that you have installed - what is the output of
dpkg -l | grep ' linux-'

Ok. This is a mixture of different kernel versions.
Switching over to lts-wily probably is the best solution.
First step in any case must be to bring the package management system back into a consistent state.

The package management system seems to be back in a consistent state, and perf-kvm hopefully installed and operational.
You might try
1. running perf kvm commands to check whether this is now running as desired.
2. updating the >200 packages for which updates are available
3. clean-up the kernel packages to reduce the installed kernel packages down to just one series.

Perf kvm is not yet installed.
root@ubuntu:~# perf kvm
WARNING: perf not found for kernel 3.16.0-30
You may need to install the following packages for this specific kernel:
linux-
linux-
You may also want to install one of the following packages to keep up to
date:
linux-
linux-
So, Do I need to try & install after removing all the unused kernel only?

You are running a version of the kernel that is one year old (3.16.0-30, current version is 3.16.0-59).
I assume that updating all packages to their up-to-date version and rebooting will provide a consistent set of the kernel tools, and the perf kvm command should then work.

We can do it by apt-get update only?
Or is there any other specific way to do it?

The designated tool to update packages is apt-get. There are other programs available doing the same (e.g. aptitude), or packages running in a xorg environment like update-manager and synaptic. If you want to install a specific version of a specific package, you could also do that with dpkg.
Why do you hesitate to update all packages at once by using apt-get?

I just wanted to be sure that I am not running the system to inconsistent
state :)
Anyhow I will do it right away. Thanks for the help

You system _was_ in an inconsistent state.
apt-get is designed to verify consistency of the expected result before executing the installation, and will not allow installation of packages that create broken dependencies.
If you are sceptic, you can test the update process with the command
apt-get--simulate dist-upgrade
to see which packages are planned to be upgraded.

Happy to see that the perf tool now is working.
If your problem is resolved, then you should mark this question document as "solved" to allow quick identification of the status.
In addition you should make up your mind about the kernel series that you want to use, and do some clean-up to remove all other versions. If you need help with that, you better create a new question document.

Sure, I will create a new question about that & mark this as solve.
Again, Thanks for the help.
