Hi,
no luck trying to reproduce the failure with builds from qemu.org,
in spite of keeping the call to ./configure as close as possible to
that for the ubuntu package and trying several git revisions.
But I think I have tracked it down to a qemu argument constructed by
libvirt for the first disk (there are 2 IDE disks in my VM):
-drive file=....,if=ide,index=0,boot=on
Using the exact invocation found in /var/log/libvirt/qemu/nbsd501-build.log
in an interactive shell (see below), the boot hangs.
But omitting the "boot=on" part in the definition for the
first disk starts the VM nicely.
My local builds from the qemu.org git repository do not exhibit that
sensitivity for the "boot=on" parameter, but strange enough I do not
even get a boot loader menu with them. Instead it boots the kernel right
away (difference from using seabios vs. some other bios?)
Since I cannot find a "boot=..." parameter for drive specifications in the
qemu manpage, maybe this is not a bug in qemu-kvm, but in libvirt instead?
Below follow a libvirt xml dump of the vm and the qemu command line
invocation as used by libvirt.

Matthias
