Converting A VMDK To VHD


Answer :

The Microsoft Virtual Machine Converter (MVMC) includes the Microsoft Virtual Disk Converter tool (MVDC.exe) that converts a VMDK file to a VHD file.

MVDC SrcDisk  DstDisk  [/?]  [/Dyn]

SrcDisk  Specifies the source VMDK disk path to be converted.
DstDisk  Specifies the path for the converted disk.
[/?]     Show Help
[/Dyn]   Indicates the destination disk should be dynamic rather than fixed.


For example:



C:\Program Files (x86)\Microsoft Virtual Machine Converter Solution Accelerator>mvdc "D:\VM\Windows Server 2008 R2 x64\Windows Server 2008 R2 x64.vmdk" "D:\VM\Windows Server 2008 R2 x64\Windows Server 2008 R2 x64.vhd"

   Tracks/Cylinder:  255
   Sectors/Track:    63
   Bytes/Sector:     512
   MediaType:        FixedMedia

Conversion Complete!  The converted file is located at: D:\VM\Windows Server 2008 R2 x64\Windows Server 2008 R2 x64.vhd


By default it creates a fixed sized VHD, which is also what is required for Azure VMs.



After converting it to VHD, it is a good idea to boot it up locally in Hyper-V, make sure it is configured for a dynamic IP and that RDP is enabled and you are able to successfully RDP into it. Then if you want to use it as a base image, you'll also need to generalize it with sysprep. If you want to use it for a single Azure VM, don't run sysprep, but upload it as a disk instead of as an image (Csupload Add-Disk instead of Add-PersistentVMImage).

I use VirtualBox (actually the CLI vboxmanage, installed with VirtualBox) for this, I had no issues installing VirtualBox alongside Hyper-V, but you can't run them at the same time, thats another thread!



Anyway at an elevated (Admin mode) prompt use



cd %programfiles%\Oracle\VirtualBox

vboxmanage clonehd "C:\tmp\file.vmdk" "C:\tmp\file.vhd" -format VHD


Note, You can extract a VMDK from an OVA with 7zip!



There has been an update to the tool to convert a .vmdk to a .vhdk.



Microsoft Virtual Machine Converter 2.0 was released around April of 2014.



Here is the link to the tool: Microsoft Virtual Machine Converter 2.0



The new tool changes the way to convert from using MVDC.exe to using a powershell cmdlet.



I followed this excellent blog to figure this out. What's new on Microsoft Virtual Machine Converter 2.0



Here is a detalied summary of how to do it.



The default install location is:



C:\Program Files\Microsoft Virtual Machine Converter


Using powershell as a local admin you can then load the cmdlet:



Import-Module .\MvmcCmdlet.psd1


After the cmdlet is loaded you can call the following:



ConvertTo-MvmcVirtualHardDisk


This will ask for the .vmdk file path:



Supply values for the following parameters:



SourceLiteralPath: D:\some.vmdk


It will then start the conversion and place the .vhdk in the following path after its converted:



C:\Program Files\Microsoft Virtual Machine Converter


I hope this helps someone else.

Converting A String To Int In Groovy

Answer : Use the toInteger() method to convert a String to an Integer , e.g. int value = "99".toInteger() An alternative, which avoids using a deprecated method (see below) is int value = "66" as Integer If you need to check whether the String can be converted before performing the conversion, use String number = "66" if (number.isInteger()) { int value = number as Integer } Deprecation Update In recent versions of Groovy one of the toInteger() methods has been deprecated. The following is taken from org.codehaus.groovy.runtime.StringGroovyMethods in Groovy 2.4.4 /** * Parse a CharSequence into an Integer * * @param self a CharSequence * @return an Integer * @since 1.8.2 */ public static Integer toInteger(CharSequence self) { return Integer.valueOf(self.toString().trim()); } /** * @deprecated Use the CharSequence version * @see #toInteger(CharSequence) */ @Deprecated public static Integer toInteger(String self) { return toInteg

"Cannot Create Cache Directory /home//.composer/cache/repo/https---packagist.org/, Or Directory Is Not Writable. Proceeding Without Cache"

Answer : if anyone pass through here, this is shorter solution: sudo chown -R $USER $HOME/.composer it seems to me the group information is missing in your command sudo chown -R <user> /home/<user>/.composer/cache/repo/https---packagist.org Shoud be sudo chown -R <user>:<group> /home/<user>/.composer/cache/repo/https---packagist.org But to avoid other permission issues, I would rather advise: sudo chown -R <user>:<group> /home/<user>/.composer/cache (you'll need access to other folders in there) and sudo chown <user>:<group> /home/<user>/.composer To make sure your user has permissions enough on the global composer folder. Mind the missing recursion so the user don't own keys created by root. If you need to find out the group: groups <user>

Android How Can I Convert A String To A Editable

Answer : As you probably found out, Editable is an interface so you cannot call new Editable() . However an Editable is nothing more than a String with Spannables, so use SpannableStringBuilder: Editable editable = new SpannableStringBuilder("Pass a string here"); If you only want to change the Spannables, never the text itself, you can use a basic SpannableString. Use Editable.Factory.getInstance().newEditable(str) From the android documentation: Returns a new SpannedStringBuilder from the specified CharSequence. You can override this to provide a different kind of Spanned.
