Since then I have been forced to leave the ubuntu server platform and went
to Redhat enterprise linux.
Canonical needs to understand that these are critical bugs that should have
been fixed in hours or days, not in weeks or months.

Any load over the number of cpu cores (X) is not acceptable.
You have X camels. Each camel can carry one sack of flour. If you want to move
more than X sacks of flour, some camels will have to make second trips.
That is how `load´ works, right? Any load over X will make

I just downloaded the oneiric server iso, and tried to install oneiric
on a KVM virtual machine. It fails with writing the linux-
image-3.0.0-16-server package, where it tries to write some kernel
modules
It crashes every time with installing the same package: linux-image-3.0.0-.
I tried with btrfs, and my own custom partitioning. This did not work so I
tried letting the installer choose lvm and its preferred choices of filesystem
sizes and type:
/ 322 MB, ext4
/boot228 MB,
Could it be that update while installing was ENABLED for all systems
affected by this bug? If so, it would corroborate my theory that it is
the linux-image-3.0.0-... package which is at fault. During my second
try at installing, I did not have this enabled, I think. So if I'm
right, it makes sense

I second this. In a typical virtualization environment, you have a
server with several real network cards. These are typically combined in
a bond device. On top of these you have bridges, and on top of those you
have vlans. Virtual servers may exist in different networks, so you need
this stacked
