[virt-tools-list] why -no-kvm flag?

[Dan Bar Dov]

Oh, and I forgot to say that this is for a newly created VM.

Existing VMs are started with:
qemu      5878 94.6  0.9 3311336 39252 ?       R    11:19   0:07
/usr/bin/qemu-kvm -S -M pc-0.11 -enable-kvm -m 2048 -smp
4,sockets=4,cores=1,threads=1 -name fc12 -uuid
464bbaa8-5ea4-1fb9-b744-c9d2c0666b30 -nodefaults -chardev
socket,id=monitor,path=/var/lib/libvirt/qemu/fc12.monitor,server,nowait -mon
chardev=monitor,mode=readline -boot c -drive
file=/var/lib/libvirt/images/pv-work1.img,if=none,id=drive-virtio-disk0,boot=on,format=raw
-device
virtio-blk-pci,bus=pci.0,addr=0x4,drive=drive-virtio-disk0,id=virtio-disk0
-drive file=/tmp/virdisk.img,if=none,id=drive-virtio-disk1,format=raw
-device
virtio-blk-pci,bus=pci.0,addr=0x5,drive=drive-virtio-disk1,id=virtio-disk1
-drive
file=/root/Desktop/SUSE_SLES-11-0-0-DVD1.iso,if=none,media=cdrom,id=drive-ide0-1-0
-device ide-drive,bus=ide.1,unit=0,drive=drive-ide0-1-0,id=ide0-1-0 -device
rtl8139,vlan=0,id=net0,mac=52:54:00:40:44:8b,bus=pci.0,addr=0x6 -net
tap,fd=21,vlan=0,name=hostnet0 -chardev
file,id=serial0,path=/var/log/gst-fc12 -device isa-serial,chardev=serial0
-usb -vnc 127.0.0.1:1 -vga cirrus -device
ES1370,id=sound0,bus=pci.0,addr=0x7 -device
virtio-balloon-pci,id=balloon0,bus=pci.0,addr=0x3

but they fail to start due to not being able to find a boot device
