Does this message appear on boot, or after some stress? on boot, and only appear when boot from network. Which qemu-kvm version? [root@kvm-4slot ~]# /usr/libexec/qemu-kvm --version QEMU PC emulator version 0.12.1 (qemu-kvm-0.12.1.2), Copyright (c) 2003-2008 Fabrice Bellard Does cherry-picking 3fff0179e33cd7d0a688dab65700c46ad089e934 help? the virtio_pci have already used this patch, still have this problem. What does info irqs show in qemu? how to collect this information? but I found if modify the slot number of balloon device from 0x03 to 0x09, the problem solved. <memballoon model='virtio'> <alias name='balloon0'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x09' function='0x0'/> </memballoon> and i found someone else also meet this problem. https://bugs.launchpad.net/ubuntu/+source/linux/+bug/584675 2010/11/25 Michael S.
