kvm installation and uninstallation failure

This bug was fixed in the package kvm - 1:59+dfsg-0ubuntu6

---------------
kvm (1:59+dfsg-0ubuntu6) hardy; urgency=low

  * Removed 08_default_tdf.patch. No longer needed.
  * Modify init script to not exit with an error when stopping if the module
    isn't loaded (LP: #183663).
  * Use the correct names for the modules in init script.

It's perfectly reasonable for kvm not not get properly configured (and
thus be marked as installed) if you don't have the proper hardware
extensions. You will not be able to use kvm.

The change I made should however allow you to remove the package?

For me, the only thing I can do is uninstall, and with the new release it works now, thanks for fixing that.

I'm going to make a suggestion for you to consider and see whether it is possible or desirable:

The problem is that some of us HAVE support for svm extensions on out systems, but bios disables it so support is there but can't be used.

When the installation script tries to load the modules, it fails and configurations fails, leaving an unconfigured package without a hint of what the problem is.

The installation script may be modified so it checks for virtualization support and do:
  1.-If there is no support (egrep ‘^flags.*(vmx|svm)’ /proc/cpuinfo), a message tell the user that the package can't work on that machine and stops the installation without trying to load the module.
  2.-If there is support, tries to load the module and if it fails, show a message telling the user to check the bios for options to enable virtualization.

Not all bioses have that option, and in some cases a bios upgrade is needed, but I think that this can help some users

I'm experiencing this problem on hardy, reopening the bug.

I'm having same problem here. Also, I can't get KVM working.

Please disconsider my previous message. Intel VT wasn't enabled in BIOS! Sorry...

I installed "kvm" package :
sudo apt-get install kvm

then remove it :
sudo apt-get remove kvm

The module was still there, I have to disable it manually :
sudo rmmod kvm_intel

Can you show me the output when you remove kvm and it keeps the module loaded?

There hasn't been any activity on this bug in quite a while...

I can install and uninstall KVM successfully in Hardy, Intrepid, and Jaunty.

Can anyone confirm that this is still a problem?

I'm going to set the priority to "High", but leave marked as "Incomplete" and expire this bug report shortly if this problem is no longer reproducible.

Thanks,

Occur after
sudo apt-get install kvm-source

Working perfectly on Intrepid before this hit

Vitaly-

This bug has been opened and closed several times now...

Please provide more detail. What exactly is the problem you're seeing? Can you paste more of the output of the issue?

What version of Ubuntu are you seeing this issue on?

:-Dustin

So, quick info about versions:

>>uname -a
Linux case 2.6.27-14-generic #1 SMP Fri Mar 13 18:00:20 UTC 2009 i686 GNU/Linux

kvm and kvm-source (1:72+dfsg-1ubuntu6)

Issue occur after some manipulation. here are positive, negative and critical flows:

1. positive
a: U can install and un-install *kvm* many times.
b: U can install and un-install *kvm-source* many times, IF KVM instaled.

2. negative
If u install *kvm-source* in case of *kvm* isn't installed .. so, welcome to hell

3. critical *I'm out*
After install *kvm-source* .. i try remove *kvm-source* by

>> sudo dkms remove -m kvm -v 72 -k 2.6.27-14-generic

It was stupid ...

>> sudo apt-get purge kvm-source

I'm know that *kvm-source* is not needed for Ubuntu systems =)))

*kvm-source* purging after manual DKMS model removing fixed by:
(just download new version, then install and purge)

>> sudo dpkg -i kvm_84+dfsg-0ubuntu8_i386.deb
>> sudo apt-get purge kvm-source

Could U say .. who provide kvm.ko, kvm_intel.ko, kvm_amd.ko !?

So, kvm.ko, kvm_intel.ko, kvm_amd.ko are provide with linux-image package.
All *.ko have bean removed by kvm-source ... waiting for new version of linux-image .. don't wanna boot with older kernel.

> waiting for new version of linux-image .. don't wanna boot with older kernel.

Just reinstall the latest kernel then , It worked for me

Vitaliy-

There is a kvm.ko, kvm_intel.ko, and kvm_amd.ko provided by every Ubuntu linux kernel. These are the kvm modules as provided by the upstream linux kernel used in Ubuntu. This version of the kvm module is generally several releases older, a bit more stable, and usually lacking some features of the latest kvm module provided by the upstream kvm source project.

The kvm-source package provides a later, more featureful, less-thoroughly-tested update of the kvm module source code. When you install this package, this source code is built against your current Ubuntu kernel headers. Once built, it replaces the kvm modules provided by your ubuntu kernel. It uses DKMS to do this.

Your reproduce case was against kvm-72, which is in Intrepid. I cannot reproduce this bug against Jaunty. Can you try there?

debian/control has for kvm-source:
Enhances: kvm

I believe that this is correct. kvm could be aded the Depends, but I don't think that's so.

This is definitely fixed in jaunty by "|| true" the following in the prerm script:
dkms remove -m $PKG -v $PKGVER --all >/dev/null || true

As far as I can tell, this bug is fixed in Jaunty. I don't believe that an SRU is warranted for Intrepid. However, if you disagree, please talk to the SRU team and propose for release against 8.10 -- the decision will be theirs.

For now, I'm marking this bug 'Fix Released', again.
