Failed to map guest I/O buffer for write access with status 0xC0000044
Hi!
It is occurring a strange error on my Windows 2004 21H1 Pro 64-bit host machine when running my guest virtual machine (also Windows 2004 21H1 Pro 64 bits):
Failed to map guest I/O buffer for write access with status 0xC0000044. Device name = [...].avhdx.
Source: Hyper-V-StorageVSP
Event ID: 8
Level: Error
The error is associated to the automatic checkpoint file, not the main .vhdx itself.
Here is the counterpart warning on guest - please note that they happen at the same time:
The IO operation at logical block address [...] for Disk [...] was retried.
Source: disk
Event ID: 153
Level: Warning
Thank you for your analysis!

It may or may not be related to these errors but there is now a new error showing up once:
