Windows XenU creation

Windows XenU creation

[shacky]

Hi.
When I try to create a new Windows XenU I get these error:

guineapig:/etc/xen# xm create win1.cfg
Using config file "./win1.cfg".
VNC= 1
Unexpected error: exceptions.OSError

Please report to xen-devel@lists.xensource.com
Traceback (most recent call last):
  File "/usr/sbin/xm", line 10, in ?
    main.main(sys.argv)

  File "//usr/lib64/python/xen/xm/create.py", line 1054, in make_domain
    os.kill(vncpid, signal.SIGKILL)
OSError: [Errno 3] No such process

I'm using Xen 3.1.0 on a Dual Opteron 2212. The AMD-V technology is
enabled by BIOS.

This is the win1.cfg file:

kernel  = '/usr/lib/xen/boot/hvmloader'
builder = 'hvm'
memory  = '512'
device_modem = '/usr/lib/xen/bin/qemu-dm'
root    = '/dev/sda1 ro'
disk    = [ 'phy:vserver/win1-disk,sda1,w',
'file:/home/mattia/win2003stdita.iso,ioemu:hda:cdrom,r' ]
name    = 'win1'
vif  = [ 'ip=192.168.1.55' ]
boot = 'd'
vnc=1
vncviewer=1
sdl=0
on_poweroff = 'destroy'
on_reboot   = 'restart'
on_crash    = 'restart'

All other Linux virtual machines works without any problems.

Where is the problem?

Thank you very much!
Bye.

I still don't think the HVM BIOS supports booting from SCSI/SATA 
drives. Try using "hda" instead of "sda" (and of course change your 
"hda" for the CDROM to perhaps "hdb").

You don't need a "root" in HVM domains.

You also can't set the IP address in a HVM domain, you need to do 
that inside windows using the control-panel (I find it easiest to use 
DHCP - but that depends on if you have a suitably configured 
DHCP-server or not).

Ok, thank you.
I changed "sda1" to "hda" and now the VM is booting up.
But windows installation doesn't start, it hangs at "Windows starting".
If I change "hda" to "hda1" the Windows installation starts, but it
doesn't recognise any hard disk drive.

Another problem is that if I try to connect to Xen with UltraVNC
Viewer it doesn't work (the vncviewer.exe process is at 99% of CPU on
my Windows client) and it hangs.
If I use RealVNC it works.

Yes, I have a DHCP server in my network...

Thank you very much!

"hda1" isn't a valid option for HVM domains, so I don't see why that 
would work better.

I guess that means that UltraVNC is broken for this particular use - 
but I know nothing about different VNC servers - I've mostly been 
using SDL over X-windows.

Ok.
Now I'm using "hda" but it isn't recognise any hard disk al all.

Any error message(s) in "xend.log"?

How about if you specify the full path to the disk-image in the config file?

It works! :-)

Thank you!!

Now my Windows VM works.

In the hardware manager of Windows Server 2003 it shows 3 unrecognised
devices, a PCI device and a unknown device.
Do you know what devices they could be?
And the serial port (COM3) isn't working (it shows me the "error 10,
impossible to startup the device"). Do you know whehere the problem
could reside?

Well, there's probably the Xen Platform Device in there, which you wouldn't 
have the driver for unless you were running paravirtualised drivers (and 
there aren't any for Windows unless you're using some flavour XenEnterprise 
or Novell's new / upcoming Windows driver package).  It doesn't do any harm, 
you don't need the platform device to be recognised in order for everything 
to work.

Wouldn't the first serial port be COM1 in Windows terminology, or am I being 
confused?  AFAIK, you can only have one virtual serial port at the moment.

So I can't find the drivers in any place?

Yes, the first serial port is COM1, but it is recognised as COM3...
