Testdrive says kvm isn't installed

Binary package hint: testdrive

When running testdrive 1.31-0ubuntu1 and choosing any “ISO” (why are we using jargon like this?), I get this error:

ERROR: You must have either /usr/bin/kvm or /usr/bin/VBoxManage installed.
HINT: Consider installing kvm if your CPU supports VT, or virtualbox-ose...
 egrep "flags.*:.*(svm|vmx)" /proc/cpuinfo && \
   sudo apt-get install kvm || \
   sudo apt-get install virtualbox-ose

But locate shows that /usr/bin/kvm is installed:

$ locate /usr/bin/kvm
/usr/bin/kvm
/usr/bin/kvm-img
/usr/bin/kvm-nbd
/usr/bin/kvm-ok
/usr/bin/kvm_stat
/usr/bin/kvmtrace_format

Testdrive should work out-of-the-box on lucid.
