Re: Call for testing: Xen 4.0

[Mick Russom <mickrussom%gmail.com@localhost>]

Ok, on current/5.99.29 now, amd64.

- The gsed/sed thing is gone because strnlen is in head. Confirmed.

- The X11 mess goes away if you specify in mk.conf X11_TYPE=modular, Confirmed working. 

- You can't compile Xen4 on a machine with xentools33 installed. Confirmed. Must remove the package if trying to compile xen4 tools. Confirmed, thanks. 

- The only other warning comes from compiling qemu-xen-4.
In 
xen-hooks.mak:56: === pciutils-dev package not found - missing /usr/include/pci
xen-hooks.mak === pciutils-dev package not found - missing /usr/include/pci

Even if you try and fix this numerous ways there is conflicts between pciutils and pci.h on netbsd. Not a major issue as this is for qemu only and shouldnt affect dom0/domU kernels. 

Finally, the problem that still persists. I cannot boot xen4 + netbsd-XEN3_DOM0 , it loads both then suddenly after seemingly finished loading netbsd-XEN3_DOM0, reboots.

No (XEN) outputs, not nothing from the hypervisor. Its stuck at this multiboot loading section it seems. 

Any help getting just Xen to load would be greatly appreciated.

This has been fixed in the latest version in the mercurial repositories.
No need for gsed.

netbsd HEAD branch has strnlen, so at least it's not a problem with
netbsd HEAD.

I didn't encounter this, but I'm using HEAD, and I don't have an X
server, but I have specifIed X11_TYPE=modular in /etc/mk.conf

Okay, this is due to the fact that you have xentools33 and make
dist-tools incorrectly uses the 3.3 version of the python Xen headers
instead. I just moved the xen related stuff from /usr/pkg/lnclude to
some other directory and it compiled fine.

I think I have a similar problem. When I use the /usr/mdec/boot 5.2,
which comes with netbsd 5.0 and do 'multiboot xen40.gz' from boot
command line, I would very briefly see the progress number of bytes
loaded and then the screen went blank for a short time. Afterwards the
computer just reboots.

If you try 'multiboot xen.gz' (from xenkernel33) you would get some
additional messages and the computer will halt and report that no dom0
kernel was specified. Is this a problem of grub vs multiboot?

Christoph, did you see this as well?

Thanks,
Toby
