Bug Description
I have not tried running kexec in a real machine yet, so it may not have anything to do with kvm.
I can load a kernel and initrd, and several things happen:
- sometimes the (virtual) machine just `powers off´
- if that does not happen, it always hangs during boot
two cases: 1 after loading initrd.img with a uncompression error
Also I checked and for maverick as a kvm guest, kexec actually works beautifully.
To post a comment you must log in.
To add why this is important to me:
I use a virtualisation host as a platform for distributing images to networked workstations.
So I run image machines as guests on the virtualisation host, and run tests of installing those images in other virtual guests. Using pxe, I load a kernel, initrd and an installation script, and do all partitioning and installation from this script. I then use kexec to start the distribution kernel of the just installed (virtual) or updated machine.
The idea is to turn on a computer (real one) and have it install and then boot into the newly installed or updated system. So I need to test this install system on virtual guests.
If kexec does not work for natty and oneiric, this rather throws a spanner into my whole installation system.
Kexec is not some unimportant and esoteric idea for me and other people. We really use it and depend on it.
Please test kexec on both virtual and real hardware.
