cpu-checker is not included in virtual host server installations from 20130120 onwards. Up until 20130118.1 this was part of virtual host installations.
A d-i syslog from an earlier image (20130118.1) which contain cpu-checker, a log from the new image (20130120), which does not have the above package and the preseed file that's used for the installations are attached.
The raring virt-host seed modified on 19-Jan-2013 , http://people.canonical.com/~ubuntu-archive/seeds/ubuntu.raring/virt-host is different from the quantal version, http://people.canonical.com/~ubuntu-archive/seeds/ubuntu.quantal/virt-host by having qemu-kvm instead of kvm in the past.
The daily smoke test for virt-host given in,
http://bazaar.launchpad.net/~ubuntu-server-dev/ubuntu-test-cases/server-tests-raring/view/head:/testsuites/virtual-host/test_ubuntu_virt_server/test.py assumes kvm-ok being present in the system and cpu-checker being not part of the installations make the tests to fail on amd64.
It's not clear where exactly the issue is: whether in the virt-host seed or packaging of qemu-kvm (by not containing cpu-checker). It would help if the bug is reassigned to the correct package if ubuntu-meta is not responsible.
