Re: [Libguestfs] disable kvm support
Yeswanth,
Below you can find an example of such wrapper:
#!/bin/sh
if [ "`echo "$@" | grep "kvm" | wc -l`" -eq "1" ];
then
args=( "$@" "-no-kvm" )
else
args=( "$@" )
fi
if [ "`uname -a | grep x86_64 | wc -l`" -eq "1" ]; then
bin=/usr/bin/qemu-system-x86_64
else
bin=/usr/bin/qemu
fi
exec $bin "${args[@]}"
This isn't awesome piece of code and may have a different behavior than you expect
(for example if your disk contains 'kvm' in the name). But it's a good start
for you.

This message probably comes from your KVM binary. I'm curious why you
want to disable KVM, since it's transparent and just makes things
faster (if available).
Anyway, if you want to remove this sort of message, you have to write
a "qemu wrapper". This is just a short piece of shell script which
edits the parameters that are passed to QEMU. Boxgrinder, for
example, contains one of these because of problems launching KVM on
Amazon EC2 guests.
