Description of problem: libvirt fails with "Invalid argument" when trying to create a new virtual machine on an AMD Magny-Cours 4x12 48 Core platform (http://www.supermicro.com/Aplus/motherboard/Opteron6100/SR56x0/H8QGi-F.cfm) with the "virt-manager" GUI or with the virt-install command line tool. This does not happen with "virt-install" if the CPU pinning is specified with the "--cpuset=auto" option. However to the best of my knowledge it is impossible to specify this option in the "virt-manager" GUI; which make it useless to create virtual machines on this platform. Version-Release number of selected component (if applicable): libvirt-0.8.3-2.fc14.x86_64 libvirt-client-0.8.3-2.fc14.x86_64 virt-manager-0.8.5-1.fc14.noarch How reproducible: Always. Steps to Reproduce: 1. Try to create a virtual machine with the "virt-manager" GUI. or 1. Try to create a virtual machine with the "virt-install" tool without using the "--cpuset" option. Actual results: -------------------------------------------------------------------------- [root@xtreme:~]# virt-install -n myvm -r 2048 --nodisks --pxe Starting install...

The problem was already solved in RHEL: https://bugzilla.redhat.com/show_bug.cgi?id=654540 The issue is explained in this thread: https://www.redhat.com/archives/libvir-list/2010-November/msg00863.html
Workaround fix by installing the following packages from Fedora 15 testing: Updating: libvirt-0.8.8-2.fc15 virt-viewer-0.3.1-1.fc15 Installing for dependencies: spice-glib-0.5-1.fc14 spice-gtk-0.5-1.fc14 Updating for dependencies: libvirt-client-0.8.8-2.fc15 libvirt-python-0.8.8-2.fc15
This package has changed ownership in the Fedora Package Database. Reassigning to the new owner of this component.
Sorry for not addressing this bug, but F14 is EOL now, so I'm closing this report. Please reopen if this is still relevant in a more recent fedora.
