qemu-launcher runs parameter:"-kernel-kqemu". This should be "-enable-kvm"

[Rolf-deenen]

When creating and starting a virtual machine through qemu-launcher, it will run unaccelerated and therefore very slow. In my case this is because qemu-launcher runs:

 /usr/bin/qemu-system-x86_64 -boot c -m 256 -hda 'MyDisk1' -cdrom 'debian-7.2.0-amd64-netinst.iso' -net nic,vlan=0 -net user,vlan=0 -localtime -kernel-kqemu

This should be:

/usr/bin/qemu-system-x86_64 -boot c -m 256 -hda 'MyDisk1' -cdrom 'debian-7.2.0-amd64-netinst.iso' -net nic,vlan=0 -net user,vlan=0 -localtime -enable-kvm >>>>>> (notice the last parameter.)

This can be changed, as I did on my machine on line 1319 of /usr/bin/qemu-launcher

Status changed to 'Confirmed' because the bug affects multiple users.

A workaround, instead of editing /usr/bin/qemu-launcher is to (in Emulator tab):
- select Acceleration: Enable
- add "--enable-kvm" in Additional arguments

Tested on Saucy.
