Using Xen to run existing Windows installation

kevpatts · 10-06-2009, 08:36 AM

Okay, Got CentOS 5.3 and have the nVidia stuff working using this. I'm now trying to get the DomU Vista running. My config file looks like:

Code:

kernel="/usr/lib/xen/boot/hvmloader"
builder="hvm"
memory=512
name="winxp"
vcpus=1
vif=['type=ioemu,bridge=xenbr0']
disk=['phy:/dev/mapper/nvidia_ebgdfiadp1,ioemu:hda,w']
device_model='/usr/lib/xen/bin/qemu-dm'
cdrom ='/dev/scd0'
vfb = [ 'type=vnc,vncdisplay=10,vncpasswd=secretpass' ]
ne2000=0
boot="c"

When I start up the machine I can't connect to it using: vncviewer localhost:5910, it just hangs. When I do xm list I get:

Code:

Name                                      ID Mem(MiB) VCPUs State   Time(s)
Domain-0                                   0     7348     4 r-----    317.5
winxp                                      2      511     1 ------      0.0

and it doesn't change.

Any pointers? I can't connect to it at all.

Okay, made more progress.

I started from scratch (reinstalled Dom0). Using virt-manager GUI I have created a new virtual machine, pointing at the physical fakeRAID partition. I set it up as a Windows Vista type machine and set it to install from "Network PXE boot". The installation fails, cause there is no PXE network to boot from, and the machine turns off. It attempts to boot normally though when I restart it, but the screen halts at: "Booting from Hard Disk..."

The CPU usage is about 24% all the time and there was hard drive activity for about the amount of time that Windows would normally take to boot, so I think it is running, I just can't see it!

My config file looks like:

Code:

name = "Vista"
uuid = "73d88190-438d-0da7-7eaa-007ef8b2e419"
maxmem = 2048
memory = 2048
vcpus = 1
builder = "hvm"
kernel = "/usr/lib/xen/boot/hvmloader"
boot = "c"
pae = 1
acpi = 1
apic = 1
localtime = 1
on_poweroff = "destroy"
on_reboot = "restart"
on_crash = "restart"
device_model = "/usr/lib64/xen/bin/qemu-dm"
usbdevice = "tablet"
sdl = 0
vnc = 1
vncunused = 1
keymap = "en-us"
disk = [ "phy:/dev/mapper/nvidia_ebgdfiadp1,hda,w" ]
vif = [ "mac=00:16:3e:09:35:0c,bridge=xenbr0" ]
serial = "pty"

Nearly there I think! Any ideas?

Sounds to me like an HVM issue, I had the same problem when I tried to boot my XP partition initially. I am not sure what to say? I also don't know why you would se tit to PXE boot. You cannot VNC to the domu, can you RDP to the machine after you give it time to boot?

I don't think it's picking up the virtual network device automatically cause it doesn't see, to be on the network.
