Re: [Xen-users] Converting a VMDK on ESX to raw

["Manoj Subramaniam (manojsub)" <manojsub@xxxxxxxxx>]

I see x86 boot sector too:

root@ubuntu:~# file win-dd.img
win-dd.img: x86 boot sector; partition 1: ID=0x7, active, starthead 32,
startsector 2048, 204800 sectors; partition 2: ID=0x7, starthead 223,
startsector 206848, 62702774 sectors, code offset 0xc0, OEM-ID "      м",
Bytes/sector 190, sectors/cluster 124, reserved sectors 191, FATs 6, root
entries 185, sectors 64514 (volumes <=32 MB) , Media descriptor 0xf3,
sectors/FAT 20644, heads 6, hidden sectors 309755, sectors 2147991229
(volumes > 32 MB) , physical drive 0x7e, dos < 4.0 BootSector (0x0)



Here’s my config file:
+++++++++++++++++++++++++

kernel = "/usr/lib/xen/boot/hvmloader"
builder='hvm'
memory = 2048

# Should be at least 2KB per MB of domain memory, plus a few MB per vcpu.
shadow_memory = 8
name = "xenwin2008"
vif = [ 'type=ioemu, bridge=xenbr0' ]
acpi = 1
apic = 1
disk = [ 'file:/root/win-dd.img,sda,w' ]
device_model = '/usr/lib/xen/bin/qemu-dm'

#--------------------------------------------------------------------------
---
# boot on floppy (a), hard disk (c) or CD-ROM (d)
# default: hard disk, cd-rom, floppy
boot="dc"
sdl=1
vnc=0
#vncconsole=1
#vncpasswd=''

serial='pty'
usbdevice='tablet'
