Windows 10: Extend C drive of Windows guest VM in KVM

Dear Team,We are using Windows server 2019 Evaluation Trial license -180 days as a KVM based virtual machine. In this VM we are trying to expand the C drive but it's grayed out in "Disk Manager". And I went trough some of the links over internet which says that its been grayed out and we need some additional tool to expand it. Please find the below links for your reference.https://getlabsdone.com/how-to-extend-windows-storage-in-kvm/https://getlabsdone.com/how-to-extend-c-drive-when-extend-option-is-disabled-grayed-out/As of now we are using trail license but after some days we are planni

Account failed logon 4625 on VM guest when clicking the entry of VM guest on failover cluster Manager on VM Host

Issue:

We found a multiple failed logon events on VM guest (evert ID 4625) with account (the account you logon on VM host) when we clicking the entry of VM guest on failover cluster manager console on VM host with Integration servers (Data Exchange) is enabled.



How to reproduce:

1. Check the “Data Exchange” is enabled on a VM guest (Enabled by default, right?)
2. Open Failover Cluster Manager Console on VM host.
3. Click the VM guest entry
4. Then you may found multiple failed logon events on that VM guest.

Reference:

https://docs.microsoft.com/en-us/vi...on-services#hyper-v-data-exchange-service-kvp



Question:

1. Does the multiple failed logons are normal or necessary?
2. If the failed logons are normal and necessary to be happened and the “Data exchange” function is good to be enabled to gather data from VM guest, any recommendation for us to correct or avoid these failed logon?

Please advise.



Constrain:

We have no chance to use same account and password on VM hosts and VM guests (because all account are managed by password management) and the Audit Policy of Audit Credential Validation must be enabled.

 

extend c drive storage space

Hi, I'm , an Independent Advisor.

Disk Management is a Windows built-in tool that supports to increase partition size with its "Extend Volume" feature. However, the program has some limitations in increasing disk space:

- Extend Volume only works on NTFS and RAW partition. FAT32 and other file systems are not supported.

- The Extend Volume will grey out if there is no adjacent unallocated space behind the target partition.

So, the ways to increasing C drive with or without adjacent unallocated space are different. Open the Disk Management, and follow the right tutorials listed below to extend the local disk C drive on your own now:

#1. Increase C Drive Space with Adjacent Unallocated Space

Step 1. Right-click This PC/My Computer, click "Manage", select "Disk Management" under Storage.

Step 2. Locate and right-click on the local disk C drive, and choose "Extend Volume".

Step 3. Set and add more space to your system C drive and click "Next" to continue.

Step 4. Click "Finish" to complete the process.

Note that if that unallocated space on your system disk is not behind the C drive, you can't extend C drive in Disk Management.

Hope this helps. Let me know if I can help you further!
