Hyper-V Program Manager
In Windows Server 2012 / Windows 8 we have introduced a new virtual hard disk format called “VHDX”. There are a number of advantages to this format:
But what if you have a collection of VHD files? Luckily, converting to a VHDX format is simple (though potentially time consuming). To do this – all you need to do is:
This will then create a new VHDX file that is a copy of your existing virtual hard disk. You can actually use the same process to convert a VHDX file back to a VHD file (if you needed to move it to an earlier version of Windows).
The current command line tool VHDtool.exe is excellent for only VHD.
Is a VHDx tool in the pipeline?
VHD tool is an unmanaged code command-line tool which provides useful VHD manipulation functions including instant creation of large fixed-size VHDs
is there any way to script this in PowerShell, in order to convert a collection? Thanks!
Sorry I didn't see the other post about powershell. I'm following you through RSS reader and didn't receive this post until now, and I just realize that there's also another newer post on the topic I was asking!
Backup - Windows 2008 native backup (either file or block level) had a 2TB limit.
Do we still have to limit these Volumes to 2TB if we use native Windows server backup?
VHDX is going to have some very large volumes created.
VHDTool is an unsupported tool that one of the Hyper-V developers made in their spare time. I do not know if there are any plans to update it.
Here is a link to my article I wrote up over last weekend on the conversion. I also included how to do it in VMM 2012 SP1 (beta). Thanks for powershell info! I will piggyback onto your blog for Powershell :)
What does the convert do when the source VHD have an error? Leave it the source in original state or crash the source VHD file?
"•And more…" obviously includes "completely incompatible with VHD and Windows 7 VHD support." I got a client's PC image from a server that survived a bulding fire here on a Windows 7 box and need to get data out of it. Of course, that's impossible. I long for the days where backwards compatibility was still important to MS. Read-only access would've been nice. :(
Can a .VHD file be used directly in Windows 8 Hyper-V? (without having to convert?)
I'm thinking about getting a new laptop, and they mostly come with Windows 8 now.
I'd love the ability to keep a .vhd file on a removable drive and use it both at work (Windows 7 host) and at home (Windows 8 host) without needing to convert. Is this possible?
To answer JCDrumKing, yes.
VHD can be read natively by Win8
when converting back down to VHD for azure migration if I didn't specify .vhd in the file extension no conversion actually occurred, it just copied the disk. Have you seen this before?
Have a look at this converter: it will convert VHD to VHDX in a fraction of a second, regardless of the size!
