I should say, we configure the kernel to reboot (panic=1), and qemu to
shutdown on reboot (qemu-kvm -no-reboot).
Rich.
Ok, so , If I have to build appliance which has a bunch of %post, %preun, %postun, %pre
operations in it's RPM SPEC file, I need to pull all of those into a custom init
script(like the one for libguestfs[1]), so that the guest kernel can detect this(run it as
PID 1) and sanely bring up the rest of the system ?
And then I need to invoke 'febootstrap-supermin-helper' like below to build the
appliance.
# febootstrap-supermin-helper -f ext2 supermin.d x86_64 kernel initrd appliance.
Where appliance is the file system. As of now, other file systems like ext3/ext4(maybe
btrfs in future) are not yet available ?
Question: After I build and boot the appliance, how about networking inside it? Any
pointers to that?
Thank Rich and Hilko. I need to wrap my head a little bit more around this and try a few
more things.
