To view logs, open Computer Management and go to System Tools > Event viewer > Applications and services > Microsoft > Windows > Hyper-V VMMS.Ĭheck the settings of Integration Services In Event Viewer, you can find more detailed information about errors than in Hyper-V Manager. The general recommendation to address different Hyper-V errors is to check Event Viewer log files. If permissions are correct, check that you have enough free storage space to perform operations with Hyper-V checkpoints. If you see an identifier instead of a user or group name in folder properties, the permissions may be incorrect. The system account that Hyper-V is running must have read and write permissions for the folder containing virtual disks and snapshot files. You need to make sure that there are enough permissions to access the needed data by Hyper-V. In this example, the virtual disk files are stored in the D:\Hyper-V\Virtual hard disks folder. AVHDX virtual disk files created when you take checkpoints. You can see a running Hyper-V VM with checkpoints in the screenshot below. To understand the cause of the error and fix it, you can do the following: A VM was improperly moved from another Hyper-V host, and correct permissions were not set.Permissions for the snapshot folder are incorrect.This issue may occur in the following situations: The common cause for these error messages is that incorrect file and folder permissions were set. Could not create auto virtual hard disk.Could not initiate a checkpoint operation. Here are some errors that you may encounter when trying to create a Hyper-V checkpoint: How to Fix Common Hyper-V Checkpoint Operation Failed Issues Volume Shadow Copy Service (VSS) and Hyper-V Integration Services are used to freeze the file system state to avoid errors when writing data to opened files.įor more information, read this blog post about Hyper-V checkpoints. Production checkpoints are application consistent.They save the disk and memory state of the VM. Standard checkpoints are crash consistent.AVHDX files are created in the corresponding VM folder. You can create a chain of checkpoints, and multiple linked. AVHDX checkpoint file instead of being written to the parent. Any changes made on a virtual disk (that is, changed blocks) are recorded to an. You can also change whether the virtual hard disk is stored in a single file or split into 2GB files.Hyper-V checkpoint is a feature that allows you to save a virtual machine’s state by creating a differencing virtual disk. The new virtual disk is still large enough to contain all the data in the original virtual hard disk. If you allocate all the disk space but later need to reclaim some hard disk space on the host system, you can convert the preallocated virtual disk into a growable disk. You can preallocate all the disk space in advance or configure the disk to grow as more disk space is needed. You can also use Virtual Disk Manager to change how disk space is allocated for a virtual hard disk. This feature is useful if you need more disk space in a given virtual machine, but do not want to add another virtual disk or use ghosting software to transfer the data on a virtual disk to a larger virtual disk. With Virtual Disk Manager, you can enlarge a virtual disk so that its maximum capacity is larger than it was when you created it. Virtual Disk Manager is included in the VMware Workstation program files directory when Workstation Pro is installed. Virtual Disk Manager ( vmware-vdiskmanager.exe) is a Workstation Pro utility that you can use to create, manage, and modify virtual disk files from the command line or in scripts.
