Created attachment 358432 [details] screenshot Host system is a stable gentoo with qemu-1.4.2 and gentoo-sources-3.10.7. When i'm trying to boot a qemu guest (also a stable gentoo system) which has gentoo-sources-3.10.7 i'll get an kernel panic if i'm enable "-cpu host". (see screenshot) Previous stable sources (gentoo-sources-3.8.13) works flawless. After searching on google i also found this bug [1], which suggest disabling pmu emulation via "-cpu host,level=9". With this gentoo boot normal but still crash when i'm trying to shutdown the guest via acpi event "system_powerdown". Guest still work if i'm using "-cpu qemu64" This happens on amd64 and x86 guests.

At this moment I can't recall if we've backported something for qemu-1.5.3 or not but you might have more success there. But since you mentioned that bug, please attach the following output: grep CONFIG_KVM /usr/src/linux-3.10.7-gentoo/.config grep CONFIG_PARAVIRT /usr/src/linux-3.10.7-gentoo/.config grep CONFIG_VIRT /usr/src/linux-3.10.7-gentoo/.config

I meant your guest. Or is it not Gentoo as well? Ah, ok. I wasn't sure about from which sys you wanted those info :) From the guest: (it's also gentoo) gkde64 ltu # grep CONFIG_KVM /usr/src/linux-3.10.7-gentoo/.config gkde64 ltu # grep CONFIG_PARAVIRT /usr/src/linux-3.10.7-gentoo/.config gkde64 ltu # grep CONFIG_VIRT /usr/src/linux-3.10.7-gentoo/.config # CONFIG_VIRT_CPU_ACCOUNTING_GEN is not set CONFIG_VIRT_TO_BUS=y CONFIG_VIRTIO_BLK=y CONFIG_VIRTIO_NET=m CONFIG_VIRTIO_CONSOLE=m CONFIG_VIRT_DRIVERS=y CONFIG_VIRTIO=y CONFIG_VIRTIO_PCI=y CONFIG_VIRTIO_BALLOON=m # CONFIG_VIRTIO_MMIO is not set CONFIG_VIRTUALIZATION=y
Just tested qemu-1.5.3 which fixes the problem for me. I'll guess i'll gonna stay with 1.5.3 so this problem is actually solved for me. However, don't know if you wanna keep the bug open.
I'm closing this bug as qemu-1.5* is already stable for quite some time.
