Hello list, I have been running a few test instances of Ubuntu 10.04 server on a few hosts, both as virtual and as physical instances. The problem I am having is that the usage of a framebuffer (that's what I believe it is) in plymouth *really* slows down the console output. It is worst when using virt-manager or virt-viewer to access the console of a virtual machine instance.
I have set the Grub default commandline in /etc/default/grub to "text", i.e. removed "quiet". When booting up it shows a lot of the usual kernel boot-up messages, which fly by very fast. Then comes a point where some switch occurs (Kernel Mode Setting kicking in?) and everything becomes dog slow. I have made a screencast to illustrate this: https://daff.pseudoterminal.org/misc/console-slow.ogg What you see is not a recording artifact or anything like it, the output really is that slow. The situation is of course better on real hardware with a real graphics card but even there the output is slower than it should be. So how can I disable this behaviour in plymouth and go back to regular console output without any framebuffer or KMS? Can I do something with virt-manager/Libvirt to mitigate this? Needless to say Ubuntu 9.10 server instances run fine and the console output is as fast as ever. It is plymouth and related changes that seem to screw things up. Any help or insight is appreciated!
