Description Juan P. Daza P. 2009-12-25 08:56:59 EST
Description of problem:
I installed qemu-system-x86-0.11.0-12.fc12.x86_64.rpm and when trying to install an OS (I tried with: Fedora 11,ubuntu 9.04 server, ubuntu 8.04 server, ubuntu 8.04 jeos, graphical installation and ncurses) this almost take 4 hours to be completed or sometimes it dies in the process.

Then I removed that package but maintain the kvm module: qemu-kvm-0.11.0-12.fc12.x86_64.rpm and decided to compile from source: qemu-kvm-0.11.0.tar.gz.

To compile from source I added the pciutils-devel.x86_64 0:3.1.4-6.fc12.rpm and then ./configure && make && make install.

Installing the same OS takes 15 minutes.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
see description
Actual results:
Installing and operating system takes too much time

Expected results:
Install and operating system in the usual time

Additional info:
 HP pavilion dv6448se
 AMD Turion(tm) 64 X2 Mobile Technology TL-56 800Mhz (with bios virtualization  parameter enabled)
Comment 1 Glauber Costa 2009-12-25 09:56:45 EST
This probably means you're not using kvm. Can you confirm that by typing "info kvm" into the monitor?
Comment 2 Juan P. Daza P. 2009-12-25 14:48:36 EST
In both cases (rpm and source) the kvm option was enabled.

As an additional test I want to reinstall the rpm, but the source makefile does not has the uninstall option.

It looks I'm wrong, I've reinstalled the rpm and check out that no kvm support is installed with the package by default, that's why its slow behaviour.

Furthermore '-enable-kvm' is not a valid option, it seems that is not compiled by default.

I did:
sudo yum install qemu-system-x86 qemu-kvm

This package has changed ownership in the Fedora Package Database.  Reassigning to the new owner of this component.
Comment 5 Michal Schmidt 2010-06-10 08:26:11 EDT
Which qemu binary do you run? For KVM support you have to run /usr/bin/qemu-kvm.
Comment 6 Juan P. Daza P. 2010-06-10 10:38:37 EDT

I've upgraded to F13 and the behaviour of qemu has been fixed (it loads correctly the kvm functionality).
