Well, anyhow, let's focus on getting this fixed, shall we? The kernel modules shipped in 2.6.24 was causing all sorts of issues, so in an effort to fix those, IIRC I grabbed what was in 2.6.25 at the time and backported that, so if I were to get this issue fixed, it should be sufficient to find anything that touches the kvm clock ABI between 2.6.25-rc and 2.6.25 final. Does that sound about right? I'm a bit confused about this, though. I was under the impression that for the KVM_CLOCK stuff to work, it'd would have to be in the host *and* the guest kernel, but our kernels don't have KVM_CLOCK enabled at all? Hmm... Looking at the code, it seems it does require host support, but it's not #ifdef'ed, so that would explain my confusion.. --=20 Soren Hansen |=20 Virtualisation specialist | Ubuntu Server Team Canonical Ltd. | http://www.ubuntu.com/ --fWddYNRDgTk9wQGZ Content-Type: application/pgp-signature; name="signature.asc" Content-Description: Digital signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.6 (GNU/Linux) iD8DBQFIY50donjfXui9pOMRAhk7AKCmiLOxU7W4ga96AljqRI2VoGUNVwCggofZ 7/MDFx3Pk06xGc/L0haFw8I= =8shi -----END PGP SIGNATURE----- --fWddYNRDgTk9wQGZ--
