I saw the same error message from grubby after installing RHEL 5.4 snap #4 on ia64/xen/pv. However the guest OS was able to boot. install.log says: Installing kernel-xen-2.6.18-159.el5.ia64 grubby fatal error: unable to find a suitable template On 5.4 Snap #4, default install with virtualization key: # yum groupremove Virtualization ============================================================================================================================================================================ Package Arch Version Repository Size ============================================================================================================================================================================ Removing: Virtualization-en-US noarch 5.2-11 installed 2.4 M gnome-applet-vm x86_64 0.1.2-1.el5 installed 121 k kernel-xen x86_64 2.6.18-159.el5 installed 88 M libvirt i386 0.6.3-16.el5 installed 7.1 M libvirt x86_64 0.6.3-16.el5 installed 7.1 M virt-manager x86_64 0.6.1-7.el5 installed 4.9 M xen x86_64 3.0.3-91.el5 installed 4.7 M Removing for dependencies: gnome-session x86_64 2.16.0-7.el5 installed 1.3 M gnome-volume-manager x86_64 2.15.0-5.el5 installed 1.9 M libvirt-python x86_64 0.6.3-16.el5 installed 431 k pcmciautils x86_64 014-5 installed 67 k python-virtinst noarch 0.400.3-5.el5 installed 0.0 virt-viewer x86_64 0.0.2-3.el5 installed 50 k Transaction Summary ============================================================================================================================================================================ Install 0 Package(s) Update 0 Package(s) Remove 13 Package(s) Running Transaction Erasing : pcmciautils 1/13 Erasing : python-virtinst 2/13 Erasing : gnome-volume-manager 3/13 Erasing : gnome-session 4/13 Erasing : xen 5/13 grubby fatal error: unable to find a suitable template grubby: doing this would leave no kernel entries.

What are the exact modifications required to the grub.conf to get the newly installed kernel to boot? I made the same mistake of attempting to remove the virtualization components due to a conflict with the serial port and the Xen console. I have booted to the rescue disk and run the "yum install kernel" and it appears to have nstalled 2.6.18-164.2.1.el5. What modifications do I need to make to the grub to get it to use this kernel? Current grub.conf looks like this: root (hd0,0) kernel /xen.gz-2.6.18-128.7.1.el5 crashkernel=128M@16M module /vmlinuz-2.6.18-128.7.1.el5xen ro root=/dev/VolGroup00/LogVol00 hgb quiet module /initrd-2.6.18-128.7.1.el5xen.img RHEL-6 yum has package protection built into core, I believe PK also has logic (although separate). This request was evaluated by Red Hat Engineering for inclusion in a Red Hat Enterprise Linux maintenance release. Red Hat does not currently plan to provide this change in a Red Hat Enterprise Linux update release for currently deployed products. With the goal of minimizing risk of change for deployed systems, and in response to customer and partner requirements, Red Hat takes a conservative approach when evaluating enhancements for inclusion in maintenance updates for currently deployed products. The primary objectives of update releases are to enable new hardware platform support and to resolve critical defects. |
