Dom0: SLES 11 SP2  
DomU: SLES 11 SP2

Help me boot the DomU, as its not booting due to file system errors, and I have to boot it via sles iso to run fsck on /.  
current configuration file /etc/xen/vm/prdsrv0057

```auto
name="prdsrv0057CDboot"
description="None"
uuid="74e73dca-3e38-fa78-0acf-b21d181165b8"
memory=4096
maxmem=4096
vcpus=8
on_poweroff="destroy"
on_reboot="restart"
on_crash="destroy"
localtime=0
keymap="en-us"
builder="linux"
bootloader="/usr/bin/pygrub"
bootargs=""
extra=" "
disk=['file:/storage/xen/prdsrv0057/prdsrv0057.raw,xvda,w' , 'phy:/dev/sr0,xvdb:cdrom,r' ,]
vif=['mac=00:16:3e:5a:b2:81,bridge=br0',]
vfb=['type=vnc,vncunused=1']
```

To boot the DomU, I followed the [https://www.suse.com/communities/conversations/how-boot-paravirtual-xen-domu-cd-rom-or-iso-sles-10-sp1-or-opensuse-103/](https://www.suse.com/communities/conversations/how-boot-paravirtual-xen-domu-cd-rom-or-iso-sles-10-sp1-or-opensuse-103/) and create a new configuration file  
/etc/xen/vm/prdsrv0057CDboot

```auto
name="prdsrv0057CDboot"
description="None"
uuid="74e73dca-3e38-fa78-0acf-b21d181165b8"
memory=4096
maxmem=4096
vcpus=8
on_poweroff="destroy"
on_reboot="restart"
on_crash="destroy"
localtime=0
keymap="en-us"
builder="hvm"
device_model=”/usr/lib/xen/bin/qemu-dm”
kernel="/usr/lib/xen/boot/hvmloader"
disk=['file:/storage/xen/prdsrv0057/prdsrv0057.raw,hda,w' , 'file:/media/sles11sp2.iso,hdc:cdrom,r' ,]
vif=[mac=xxxx,]
vfb=[type=vnc,vncunused=1]
apci=0
acpi=1
pae=1
serial="pty"
```

But I got the following error:  
hypvsr:/etc/xen/vm # xm create prdsrv0057CDboot  
Using config file “./prdsrv0057CDboot”.  
Error: Errors were found at line 13 while processing ./prdsrv0057CDboot:  
None

here line 13 is `device_model=”/usr/lib/xen/bin/qemu-dm”`  
If I remove the quotes(") i.e `device_model=/usr/lib/xen/bin/qemu-dm`  
then I got the error:  
hypvsr:/etc/xen/vm # xm create prdsrv0057CDboot  
Using config file “./prdsrv0057CDboot”.  
Error: Errors were found at line 13 while processing ./prdsrv0057CDboot:  
device\_model=/usr/lib/xen/bin/qemu-dm

please help me boot the PV DomU
