Hi, i installed kvm-83 on xubuntu-amd64/kernel-2.6.7-11.
i notice some problem with -net downscript.
my kvm start up script like this:
qemu-system-x86_64 ... ... -net=20
tap,ifname=3Dtap0,script=3D/path/kvm-ifup,downscript=3D/path/kvm-ifdown
when the guest shutdown, kvm pass all argument to downscript.

the command like this (kvm-83):
/path/kvm-ifdown "tap0,script=3D/path/kvm-ifup,downscript=3D/path/kvm-i=
fdown"

kvm-82 only pass tap0 to downscript like this:
/path/kvm-ifdown "tap0"

and i notice both kvm82/kvm83 not installed modules to=20
/lib/modules/2.6.27-11-generic/kernel/arch/x86/kvm/{kvm-amd,kvm-intel,k=
vm}.ko
it only rename the old modules to {kvm,kvm-intel,kvm-amd}.ko.org.

please help, thank you.
