[Bug 820885] New: virt-manager Xen VM install fails due to "No kernel was found." message
https://bugzilla.novell.com/show_bug.cgi?id=820885 https://bugzilla.novell.com/show_bug.cgi?id=820885#c0 Summary: virt-manager Xen VM install fails due to "No kernel was found." message Classification: openSUSE Product: openSUSE 12.3 Version: Final Platform: Other OS/Version: openSUSE 12.3 Status: NEW Severity: Critical Priority: P5 - None Component: Xen AssignedTo: jdouglas@suse.com ReportedBy: rschaffner@novell.com QAContact: qa-bugs@suse.de Found By: --- Blocker: --- When doing an opensuse Xen VM install on a Xen host running openSUSE 12.3 using virt-manager, the install fails after the first reboot with a "No kernel was found. The installation may have failed." message. It looks like the openSUSE Xen VM is trying to use the same temporary kernel file after the first reboot that it used for the install but that tmp file is no longer there.

Everything runs smoothly until the first reboot. After that we see this error because it is trying to use a temporary kernel file that no longer exists instead of switching over to using pygrub or some other bootloader to pull the correct kernel from the newly created VM. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

When I upgraded my Xen host to opensuse 12.3, I disabled xend and imported all my existing VMs into libvirtd using virsh. I can see them through virsh and virt-manager and have no trouble managing my existing Xen VMs through libvirtd. I can't pull up a console for then through libvirtd ( I have to use xl ) but that will be a separate bug. :) I can create the VMs manually without virt-manager. I can also get virt-manager to work (sort of) by creating the disk manually using qemu-img and passing it to virt-manager for the install. If I do that, virt-manager wont delete the disk after the failure and I can modify the config file that virt-manager creates to start the VM. The problem I have is with creating new VMs through virt-manager due to it's inability to find the correct kernel after the first reboot. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

To preserve the image after an error, manually run vm-install at the command line with the '--preserve-on-error' flag. Normally vm-install should be writing out a post install configuration file that removes the temporary kernel and initrd and uses pygrub (if a pv guest) to start up the guest. Try manually running vm-install with the --debug flag which dumps out lots of information as things progress. If you could capture that and attach it to this bug would be helpful. I haven't been able to dup this problem yet but I wasn't using qcow2 which may be where vm-install is failing. It tries to validate the image after an install and will display this error if for some reason it fails. Also, could you show the version of vm-install you are using? -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
