Today i should convert a machine with XenConvert to XenServer, but it come with these errors:

Failed to discover 1 of 2 volumes on the destination disk!
Enable Automount on windows server Enterprise edition and run Disk Management once to take effect

What i did to fix it was:

First enable automount

If it still not working try this:

1. Close XenConvert.
2. Open a command window.
3. Change to the XenConvert installation folder
4. Mount the VHD:
   
   Shell

   cvhdmount -p 1 <VHD file path>

   1	cvhdmount -p 1 <VHD file path>

5. Open Windows Disk Management, then wait for the disk to appear online in Windows Disk Management, maybe you need to rescan
6. Verify that the volumes are accessible
7. Dismount the VHD
   
   Shell

   cvhdmount -e 1

   1	cvhdmount -e 1

8. Last thing to is editing XenConvert.ini file in c:\program files\citrix\xenconvert\xenconvert.ini
   And put this under [Parameters]
   VolumeDiscoveryTimeoutAsSeconds=120

Then try run XenConvert again.
