How do you setup Solaris to run on a linux dom0?  Is there a Solaris

I copied the files (boot_archive  mydomU.py  root.file  unix)
from Solaris to my linux domU and gave xm create a whirl to see what
would happen.


I'm assuming these were setup from vbdcfg? Did you
run this domU on a solaris dom0 without any problems?

i.e.
    http://www.opensolaris.org/os/community/xen/How-To-07-2006/Solaris-domU/

xend-debug.log says:
    ERROR: Initial guest OS requires too much space
    (1748MB is greater than 400MB limit)
     (0 = Success)
     ERROR: Error constructing guest OS

xm crate itself said:

# xm create -f mydomU.pyUsing config file "mydomU.py".

    Error: (9, 'Bad file descriptor')


Could you double check that these are valid.. Does
the size of each file make sense? i.e. how big
are the unix and boot_archive files?

# ls -l /vol/local/solaris/unix
# ls -l /vol/local/solaris/boot_archive
# ls -l /vol/local/solaris/root.file

The xend-debug.log is coming from setup_guest() in libxc.
it basically saying the the memory required by the kernel (unix),
the ramdisk (boot_archive), and some minor overhead pages are
more than the memory you allocated for the domU.

Off the top of my head, the only reason I could see that is if
one of those files was wrong?

The xend.log recorded all this:
