Qemu parameters invoking via libvirtd under debian sid (32bits)

I met a trouble on installing Fedora 13 Beta using virt-install under debian sid (32bits).
The trouble is that qemu died with no errors immediately after invoke virt-install.

Consulting the source of libvirt-0.8.0, I found the log which are shown about all argument parameters and all environmental values in invoking qemu.

The log are always stored under /var/log/libvirt/qemu/.log.

It is very convenient to find out the reason of dying qemu.
