Xen users - May 2006 - Dom0 boot failure with latest xen-unstable

ewHi,

So, I''ve been struggling with some strange problems in my Xen-powered  
server, and I decided that before I ask the list i''d better upgrade  
to the latest xen code (famous last words). So I downloaded and  
installed xen-unstable-src.tgz as of 5/8.

The boot process on the system now goes something like this: The xen  
part goes ok. The 2.6.16 kernel starts loading. Then it freezes.  
First it froze loading the lp driver. I built a new kernel with the  
parallel port driver as a module. So now it freezes loading the USB  
driver. I built another kernel with Xen''s default config (the  
previous one was mine, optimized for my MB), that one froze somewhere  
during IDE bus scanning. Basically, every time I change something in  
the xen0 kernel build, it freezes at a different place (unrelated to  
the change).

I just tried building Xen using xen-unstable.3-src.tgz (the oldest  
tarball available, from the 6th), still same problem.

It''s very amusing, I know. Now, if anyone could stop laughing long  
enough to say if they can guess what''s going on, I''d be very
grateful.

TIA, Itai

This keeps getting funnier.

Upgraded to today''s xen-unstable and kernel 2.6.16.13. With the  
default xen0 config, the boot got as far as starting SSHD, then  
froze. With my custom config the system booted with no apparent  
problems... but now I can''t start any domains - they all result in  
the No space left on device while writing /vm/... message.

Tried xenstore-control check. Removed /var/lib/xenstored/tdb. Nothing.

Any guesses?

Laugh, eat, drink, waste time.

Everything is back to normal. I erased the dom0 system, installed a  
clean Sarge and built xen. My guest domains are starting up with no  
problems.

We return you now to your regularly scheduled programming.
