Hyper-V virtuals on QEMU/KVM
article #373, updated 1945 days ago
The following article is most interesting:
The file format used by Hyper-V in its VHD files, is actually exactly the same as the VPC format used in Virtual PC. And KVM and QEMU do know how to read VPC. So you can do it directly, without conversion; just import an existing disk image into a new KVM virtual and you are there.
But if you want to convert, you can use a utility called “kvm-img”. In some references and some systems, it’s called “qemu-img”. The idea is, that a command line much like this:
qemu-img convert -f vpc -O raw hyper-v-disk-image.vhd kvm-raw-disk.img
will convert your Hyper-V virtual disk image to the “raw” type image which is first on the list for KVM and QEMU.

Looks much better than overwriting the MSI, which has now failed on me twice.
Advanced Memory Management, XP/2003/Vista/7, & virtuals

Start reading here:
and try /3GB and/or /PAE (search for it in the above) if you’re on XP or 2003. If you’re on Vista or 7, go here:
and try PAE and very possibly IncreaseUserVA.
I have found very good performance of 32-bit Windows as virtual guest, in a VirtualBox environment hosted on 32-bit Fedora 14 Linux, using the PAE kernel on Linux and /PAE (or BCDEdit /SET PAE) in the virtual. If you use PAE in the kernel, do make sure to use PAE in the virtual, or there will be an extra and expensive memory processing step required at all times. This is to be done even if the virtual is configured with smallish RAM, e.g., 1G.
Create a VHD (virtual hard drive) from a running server
article #242, updated 2294 days ago
creates one or more Microsoft VHDs, suitable for use in Hyper-V and Virtual PC, from the drive(s) and/or RAID volume(s) of a running server or workstation. Server 2003 / XP and up.
