I have a virtual machine that was running Ubuntu Server 9.10 under Hyper-V on Windows Server 2008 R2 and the performace was acceptable. I run it in text mode with no X windows. I use it for LAMP. I upgraded to 10.04 and now the console is almost unusable it is sooo slow. It starts booting and text is painting fast and then something happens to the video. The screen goes to green, draws a few vertical lines, then clears back to a black screen but you can tell it is in a new video mode and the rest of the boot process and logging in and using the system is horrible because scrolling and redrawing of the screen crawls. Never had this problem in 9.10.
I'm sure that it is a "flipping from a text to a graphic text mode" issue at some point during the boot process. I've tried playing with kernel options (vga and nomodeset) but neither helps. When it gets about half way through the boot, something is making it change and then I'm screwed.
Any ideas would be greatly appreciated. I enabled ssh and I can ssh in with no problem. Performance is great so it is definitely the console now being in a "graphics mode" kind of issue. I can ssh but sometimes you still have to use the console and it's terrible!
