Cannot mount Windows VM in OS X Yosemite

Can anyone help?
I'm using Parallels 9 with Yosemite.
All of my settings seem to be correct but I can't access the Windows virtual disk from OS X - it is not present on the desktop and it cannot be accessed any other way I've tried either (from terminal or Finder). I can access OS X file space from the Windows VM.
Finder preferences is set to show "Connected servers" and Parallels sharing options are set to mount virtual disks to Mac desktop.
When I try to mount the pvm file manually using Parallels Mounter (9) I get an error telling me that "Parallels Mounter is unable to open the virtual hard disk. Either the hard disk has no volumes of its file system is not supported or contains errors".
 
I have the exact problem. Ever since updating to Yosemite I was unable to use Parallels Mounter on any of my images or hdds, including a Windows 7 and Debian machines.

Parallel Mounter says:
Parallels Mounter is unable to open the virtual hard disk.
Either the hard disk has no volumes or its file system is not supported or contains errors. Start your virtual machine and check the disk for file system errors.​

No matter what combination of sharing settings I choose in the virtual machine configuration there is never a /Volumes/C mount so I can't access my Windows files from Mac.

Parallels has broken this in version 9 and there is no way to fix it. Some people byte the bullet and upgrade to parallels 10 for a fee but I think it is unfair to break a feature and require payable upgrade for the fix.
 
Exact same problem here :(

Seems something is wrong with the Parallels FileSystem driver, I am seeing the following error in /var/log/system.log:

com.apple.kextd[20]: ERROR: invalid signature for com.parallels.filesystems.prlufs, will not load

This is also affecting me, and this is a mission critical feature for my work. I have created a problem report 53847076.
Virtual Machine disks no longer mount in OSX Yosemite since upgrade. I have fully up-to-date Parallels 9. I cannot manually mount disks with Parallels mounter either; I receive an error that appears to be permissions based. I have checked permissions of the virtual hdd, and even made a copy, given all users read/write and replaced original drive with updated copy.
I hope that you are working to address this issue.

Why is there no activity from Parallels support on this issue? Parallels 9 is broken for Yosemite users, although you state support of this OSX version for it. I'll restate that this is a mission critical issue for my work and I'd appreciate an update from staff on whether this is being investigate/ when we can expect resolution or I'll have to abandon your product.
 
Have exactly the same problem reported here - cannot mount C: drive in Mac, or use PT Mounter either. Spent all morning on it - thinking that it must be a new setting / reset issue with Yosemite/Finder etc. Then tripped over this thread. Very annoying. Let's hope they fix it quickly.
 
Submitted a Tech Request yesterday. They have come back asking me to Repair Permissions on the Mac Hard Drive, and to resetpassword. All done - no change. Won't mount C: drive in the Finder when VM is running, and Parallels Mounter still reports the same error message when trying to mount drive when VM not running. Error message attached. Will await next instruction from on high........

ok folks - don't bang your heads against the wall any more - looks like Parallels 9 does not support this feature in Yosemite. I am now at Level 2 support and this is the latest message:
The issue was reviewed by Secondline Technical Support.
The issue you have reported is caused by the major changes in Yosemite OS. Parallels Desktop 9 was designed for Mavericks OS.
Please note that the new version of Parallels Desktop 10 is fully compatible with Mac OS X 10.10 Yosemite.
 
I'm using Parallels v10 and am seeing this issue. I have installed and reinstalled Parallels Tools. Checked all the appropriate file sharing options under Configure for the VM. Installed MacFUSE (which doesn't work in the latest MBP with Yosemite). Installed the predecessor, FUSE for OS X v2.7.5. Nothing works.

Let me throw a wrench in this engine and say that yesterday, the VM's drive was available in the finder. Worked great. Today, after restarting the VM, it does not work. And I went through all those steps I listed above again.
 
I am running Yosemite (10.10.3) along with Parallels 10.2.1 (29006) and I can't mount my Windows VM in OSX either. This is not just a Parallels 9/Yosemite issue. I ahve all my settings in Parallels set to allow access to Windows folders under Mac.

Hi RobF1,
Please follow the steps suggested below and let us know how it works.
1. Enable smart mount by to > Virtual Machine configure ( http://kb.parallels.com/117287 )> Options > Sharing > under share Windows > Select shortcuts to Virtual disks on Mac desktop.
2. Install Parallels Tools manually as suggested at http://kb.parallels.com/en/112609 and check if the issue still persisting.

All options under Share Windows are checked and I have installed and reinstalled Parallels Tools multiple times.
 
@Ram@Parallels
Same problem than @RobF1 here: Parallels Mounter doesn't mount my VM, a 18GB Windows XP file, as a drive I can read/write in OSX. When I try "Open with... Parallels Mounter" on my VM file, I can see the dialog "Mounting WindowsXP.pvm...", then it disappears and nothing else happens, VM is not visible. I've checked with "Activity Monitor" and it shows two processes with the name "Parallels Mounter", you can quit them without forcing them, but nothing else.

FYI, I'm running latest version of OSX Yosemite, v10.10.4, and latest version of Parallels, v10.2.1 (29006). I'm also using TuxeraNTFS to read/write my BootCamp partition, but disabling it doesn't make any difference.

If you need any other info, just ask.

Please do your best to solve this issue, I DO need to be able to read/write that VM file from OSX for my work. Thanks.

Saluditos,

Ferran.
