Description melchiaros 2011-09-05 12:27:02 EDT
Created attachment 521519 [details] message and libvirt logs Description of problem: I´ve just installed fedora as my hostsystem. Until now I reside on openSUSE. I´ve tried to get up kvm-qemu on fedora, but the probolem is that fedora seems to fallback for all guest to quemu, which makes the guests I´ve installed incredible slow. I attach the libvirt logs and the kernel log. As I pointet out, I´am new to fedora, so when there is something I can provide give me a hint. Version-Release number of selected component (if applicable): [user@localhost ~]$ rpm -qa | grep kvm qemu-kvm-0.14.0-7.fc15.x86_64 [user@localhost ~]$ rpm -qa | grep qemu gpxe-roms-qemu-1.0.1-4.fc15.noarch qemu-system-x86-0.14.0-7.fc15.x86_64 qemu-kvm-0.14.0-7.fc15.x86_64 qemu-common-0.14.0-7.fc15.x86_64 qemu-img-0.14.0-7.fc15.x86_64 [user@localhost ~]$ rpm -qa | grep virt-manager virt-manager-0.8.7-4.fc15.noarch [user@localhost ~]$ rpm -qa | grep libvirt libvirt-0.8.8-7.fc15.x86_64 libvirt-python-0.8.8-7.fc15.x86_64 libvirt-client-0.8.8-7.fc15.x86_64 [user@localhost ~]$ rpm -qa | grep kernel abrt-addon-kerneloops-2.0.3-1.fc15.x86_64 kernel-220.127.116.11-26.rc1.fc15.x86_64 kernel-headers-18.104.22.168-0.fc15.x86_64 kernel-22.214.171.124-0.fc15.x86_64 [user@localhost ~]$ How reproducible: Install fedora15 on a AMD phenom2(6 core), T1100 16GB ram, 2TB harddisk. Bring the system to fedora15 updates. Install several guest: Dwebian6, Scientific linux6, windows Xp Sp2, Microsoft Server 2008 R2. -> not in parallel to prevent harddrive from getting ill. Steps to Reproduce: 1.See above 2. 3. Actual results: Expected results: I expect the known speed of KVM as I get it on other host before. Additional info: 1..The kernel log shows some issues with libvirt -> you should have a look. 2.May be that I missed to install a KVM package or something. I´ve just installed to virtualisation metapackage. In the moment I cannat check(yum is buisy for a longer while). -> Please point me on when it is like this.
Comment 1 melchiaros 2011-09-05 12:34:46 EDT
No, seems not that I´ve forgot kvm packages to install. There is also a other issue with Microsoft Server 2008 R2. -> I open a new ticket for that.
Comment 2 melchiaros 2011-09-05 13:10:20 EDT
To prevent the question: Hardware virtualisation is enabled on my sytem. -> It works also properly of my gone openSUSE installation.
Comment 3 melchiaros 2011-09-05 13:55:16 EDT
I´ve found this: http://www.linux-kvm.org/page/FAQ#How_can_I_check_that_I.27m_not_falling_back_to_QEMU_with_no_hardware_acceleration.3F I attach teh dmesg output. But it shows nothing.
Comment 5 melchiaros 2011-09-05 13:58:20 EDT
"/dev/kvm exists and you have the correct rights to use it" It exists and I´ve started virt-manager with sudo-> so the rights should be there.
Comment 6 melchiaros 2011-09-05 14:00:04 EDT
[user@localhost ~]$ lsmod|grep kvm kvm_amd 45848 7 kvm 317808 1 kvm_amd In the moment there are only running 2 guests on my system, not 7 !
Comment 7 melchiaros 2011-09-05 14:05:16 EDT
I´ve also made the switch to fedora, bacause I´ve thought that here I am nearer to the source of kerne-virtualisation:-> Could you bring KVM in a good state? There is also version0.15 released. The new one seems to be not in your repros.(-> also testing-updates).
Comment 8 Justin M. Forbes 2011-09-13 11:50:48 EDT
qemu-0.15.0 is in the Fedora 16 tree, and is available for Fedora 15 users by using the virtualization preview repository: https://fedoraproject.org/wiki/Virtualization_Preview_Repository If you restart libvirt, does that fix things?
Comment 9 Fedora Admin XMLRPC Client 2012-03-15 13:53:28 EDT
This package has changed ownership in the Fedora Package Database. Reassigning to the new owner of this component.
