** Description changed: I have a Rackspace cloud server which started its life as Lucid. Recently, Rackspace offered to turn over control of the kernel to users via pv-grub per http://www.rackspace.com/knowledge_center/linux_kernel_management I basically carried out the instructions in the above link, upgrading my Lucid install to Maverick, but I have not been able to get the Maverick kernel to work. It looks to me like the Maverick kernel is lacking Xen support, since the /dev/xvda1 device is missing. I now have the server upgraded from Lucid to Maverick, but still running under the Lucid kernel. Whenever I try to edit /boot/grub/menu.lst to replace the paths to the Lucid kernel and initrd with those for the Maverick kernel and initrd, the reboot fails as below. This is my current working /boot/grub/menu.lst: default=0 timeout=5 title=DISTRO-NAME "Ubuntu 2.6.32-33-server" root (hd0) kernel /boot/vmlinuz-2.6.32-33-server ro console=hvc0 root=/dev/xvda1 initrd /boot/initrd.img-2.6.32-33-server and what I have been doing is just changing the vmlinuz and initrd file names the the Maverick kernel values. This is what I see in the console when the reboot fails, apparently because it could not find the root device: [ 0.170442] device-mapper: uevent: version 1.0.3 [ 0.170588] device-mapper: ioctl: 4.17.0-ioctl (2010-03-05) initialised: [email protected] [ 0.170828] device-mapper: multipath: version 1.1.1 loaded [ 0.170836] device-mapper: multipath round-robin: version 1.0.0 loaded [ 0.171301] cpuidle: using governor ladder [ 0.171307] cpuidle: using governor menu [ 0.171667] TCP cubic registered [ 0.171807] NET: Registered protocol family 10 [ 0.172369] lo: Disabled Privacy Extensions [ 0.173098] NET: Registered protocol family 17 [ 0.173169] powernow-k8: Found 1 Quad-Core AMD Opteron(tm) Processor 2374 HE (4 cpu cores) (version 2.20.00) [ 0.173192] [Firmware Bug]: powernow-k8: No compatible ACPI _PSS objects found.
