-------- Message original -------- Sujet: [Qemu-discuss] pci-assign error Date : Wed, 03 Apr 2013 12:12:15 +0200 De : Jean Parpaillon <jean.parpail...@free.fr> Pour : qemu-disc...@nongnu.org Dear all, I'm trying to assign a PCI graphic card to a qemu guest. When I start the guest with libvirt, I have the following error in /var/log/libvirt/qemu/sofa.log: LC_ALL=C PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin HOME=/root USER=root
