What are pending shap-shot merges ?

At the time of deleting a snapshot from any of the virtual machines automatically deletes from the GUI, but it does not merge into the parent VHD till the VM is off and merge completes. This can cause a major issue if you run out of space and .AVHD keeps increasing. Due to insufficient space to merge the snap-shot, VM will automatically pause.

The only solution to this is monitoring the pending deleted merges by monitoring the following entry in the config file of each Hyper-V VM :

configuration/global_settings/disk_merge_pending = true read more

I am getting many errors such as 0x800704C8, 0x80070037 and 0x800703E3, what do they mean ?

Let’s analyze them one by one :

a. 0x800704C8 : Requested operation cannot be performed on a file with a user-mapped section open
b. 0x80070037 : Failed to Power On with Error ‘The specified network resource or device is no longer available.’
c. 0x800703E3 : I/O operation aborted because of thread exit or application request

Thes issues can be caused by an Anti-virus software installed in the parent partition and real-time scanning component configured to monitor the Virtual Machine Files read more
