[Xen-users] Reply for the windows virtualization (Ko0nz) Xen-users Digest, Vol 27, Issue 110
Hi koonz
I noticed that you are using the cdrom parameter in the config file I
believe that''s no longer used in recent versions of Xen. I am running
debian etch here atm and am trying to virtualize windows guests aswell
I am able to boot up windows with the following configs although they do
tend to hang at some point during the installation.
----- Config windows xp -----
import os, re
arch = os.uname()[4]
if re.search(''64'', arch):
arch_libdir = ''lib64''
else:
arch_libdir = ''lib''
name = "xp-001"
acpi = 1
apic = 1
pae = 1
builder = ''hvm''
device_model = ''/usr/lib/xen-3.0.3-1/bin/qemu-dm''
kernel = "/usr/lib/xen-3.0.3-1/boot/hvmloader"
vcpus = 1
memory = 1024
#boot (a) floppy (c) hard disk (d) cd-rom
boot = ''dc''
vif = [''type=ioemu, bridge=xenbr0'']
#LVM Based Disk
disk
[''phy:/dev/ovspc170/winxp,ioemu:hda,w'',''file:/home/winxp/winxp_sp2.iso,h

on_poweroff = ''destroy''
on_reboot = ''destroy''
on_crash = ''destroy''
vnc = 1
vncviewer = 0
sdl = 0
stdvga = 0
Kind regards,
Ldj

hi!
i have a debian (lenny), 2.6.18-4-xen-vserver-686 kernel, i successed
running with the debian etch guest.
But trying the windows Xp with a partition, i can''t:
here''s the output of my "xm create winxp.hvmy"

Does the xm config file format change between 3.0.3 and 3.1.0?
I''m running fedora 6 and I just built and installed the xen HV and
tools
from source but left the kernel in place. That means I''m running a
3.0.3 kernel on Dom0 with 3.1.0 HV and tools.
Anyway, I go to start a DomU that was working fine before upgrading
the HV and tools and I get
Using config file "/etc/xen/tintin2".
Error: (22, ''Invalid argument'')
Not a very helpful error message. I poked around in create.py and found
a
place to print a traceback, and it looks like this:
Traceback (most recent call last):
File "/usr/lib64/python2.4/xen/xm/create.py", line 1051, in

File "//usr/lib64/python/xen/util/xmlrpcclient.py", line 55, in

return self._parse_response(h.getfile(), sock)
File "/usr/lib64/python2.4/xmlrpclib.py", line 1286, in
_parse_response
return u.close()
File "/usr/lib64/python2.4/xmlrpclib.py", line 744, in close
raise Fault(**self._stack[0])
Since the error is coming from something that seems to be for parsing
XML and my config file is the same old non-xml config file I was using
with 3.0.3, I''m wondering if my config file is supposed to be XML now.
If so, is there a tool to convert a 3.0.3 config file to the XML
format?
Thanks

Thank you Petersson. Looks like I may want for the arrival of IOMMU
