    Thank you for your feedback. If you wish to check and make sure there are no issues with snapshot deletion, you can create a new snapshot and delete it.

    I am having the same problem -- very, very slow Snapshot deletion (trying to reduce VM Size). Report 349405911

    I'm having the same problem. When I sat down to use the Mac this AM, snapshot deletion was running and was 52% completed. An hour later it was still 52% completed. Having no idea what was going on, and figuring the VM was hung, I shut down the VM, rebooted the Mac and restarted the VM. The deletion started from scratch on restart. It's been running for over 12 hours now and it's only 42% completed. I'm going to let it run all night to see how far it gets, but I can't go another full day without access to my Windows system.

    If it looks like it won't complete by the end of the day, I believe my only recourse will be to shut it down and reload the pvm from the Time Machine backup taken two days ago, then merge and delete the snapshots with the Terminal command. Can I do that immediately after loading the backup or must I run the VM to shut down SmartGuard first? I'm concerned if I do that the deletion could start again.

    If I'm successful, I will never use SmartGuard again. From what I've read here, it's too dangerous because merge/deletion can't be stopped. I understand that once it begins, there's no way to unmerge or reset to the previous state, but that means if something causes it to run very slow, which appears to have happened to some users from time on time over the past three years, and your developers have been unable to determine the cause, the user is screwed and loses access to the VM for what could be an unacceptable length of time.

    I have been waiting over an hour and half now for automatic deletion of snapshot that occurred as soon as I started the Windows 10 VM. I can't afford to wait any longer, I need access to my machine. It's insane to hijack a system like this for hours like have been reported here.

    I too will disable this stupid SmartGuard once I have figured out how kill this process and recover.

    Have just posted a Parallels Tech Report ID 363548746.

    Any updates?
    I've been watching this. SmartGuard snapshot management is pretty painful, both the long times and the inability to cancel.
    If there are solutions that solve the speed problem (potential w/ KevinB7's reponse), then this needs to be productized, ie. if a user has settings or configs that slow things down, at a BARE MINIMUM this should be in information that is clearly discussed (and linked to KB article if needed for additional details) when the user presses "?" on the bottom left of the Manage Snapshots
