Subject: [Qemu-devel] mask specific partition from guest
Date: Thu, 08 Nov 2012 06:19:13 +0800 [thread overview]

Hi all,
I am trying to boot a real Linux OS inside qemu.
The OS resides on a real disk with a partition layout:
1. data
2. os
3. data
Partiton 1 is being used by the host and i would like to hide it from guest.
In virtualbox/vmware, this can be done by creating a vmdk file marking corresponding extent as "ZERO" and it will ignores all writes.
e.g.
version=1
encoding="UTF-8"
CID=0510e33b
parentCID=ffffffff
isNativeSnapshot="no"
createType="partitionedDevice"
RW 34 FLAT "header" 0
RW 2014 ZERO
RW 204800 ZERO
RW 262144 ZERO
RW 125364224 ZERO
RW 1124425728 FLAT "/dev/sdc" 125833216
...
How can this be done in qemu/kvm?
ching
