Control: tag -1 + wontfix
Package: qemu-system-x86
Version: 1.6.0+dfsg-2
Severity: wishlist
Hi folks,
Would you mind to continue to provide "kvm" as a wrapper for
running "qemu-system-x86_64" with hardware virtualization?
"kvm" is easy to type and much less error-prone than
"qemu-system-x86_64 -machine accel=kvm".
Please see comments in
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=716752#10
`kvm' command, in the form it exists now, is a bad practice.
If you want kvm extensions, you have to enable them explicitly
and the command should fail if these aren't available. Or else
it behaves in an unpredictable way - sometimes it will enable
kvm, and sometimes will work in tcg mode.
But I can't change `kvm' command because it worked this way for
a long time before, and by enforcing kvm it is possible to break
users setups where kvm isn't available.
So I think it is a `wontfix' for now. Maybe in jessie+1 it will
be okay to actually enforce kvm in there, but again I'm not sure.
Maybe we can introduce another wrapper, such as qemu-kvm, but
I'm afraid it will be even more confusing.
BTW, `-machine accel=kvm' is the same as -enable-kvm, which is
shorter.
Thanks,
/mjt
