Hello everyone, I have Hyper V integration working properly, but needed to do an update to 2.6.18-274.12.1.el5-x86_64. Since then, it no longer works. As discovered previously, one needs to rebuild Hyper V Integration tools due to the kernel panic. http://www.sudonym.com/398/kernel-panic-after-yum-update-centos-with-hyper-v-linux-integration-components Done. But I'm getting an error message: "Your system DOES NOT support the timesource driver" when running make. adjtimex is installed - adjtimex-1.20-2.1. Any ideas? I've successfully followed the same steps in the past, but right now they are just not working. Thank you! Asya
