extent the windows C:\ partiton.

English Virtualization
1

I am running windows 10 in a virtual machine on Tumbleweed.

Windows started to complain that the disk is almost full.

I started Gparted, and made the partition bigger.

I can’t seem to find a way though in windows to extent the c drive/.

It still is the same size, and extent a partition is greyed out in the diskmanager of windows…

Am I trying something not possible?

sdb5 is the disk I am talking about, it was 20 gig and is now 79,4 gig.

I can in windows see and format the free space, but I can’t extent the c drive ?
What am I doing wrong ? Or do I need to reinstall windows in the virtual machine? (I hope not)

Isn’t that a pure Windows question?

I ask because you may be better and sooner helped in a Windows forum.

You might be right, I was already wondering about that. :slight_smile:

Bit worried they will blame linux, but I could leave out the part, I am running win 10 in a virtual machine on Linux.

Virtualisation uses an Container as disk???

I think I found an answer.

Windows diskmanager can’ t do it, I need third party software.

6

What Virtualisation do you use?

7

Virtual manger with libvirt. and qemu.

8

Containers are stored in /var/lib/libvirt/images, so as root:

ls -al /var/lib/libvirt/images

[sudo] password for root:  
total 31345920 
drwx--x--x 1 root root          48 nov 17 13:40 . 
drwxr-xr-x 1 root root          88 nov  6 22:01 .. 
-rw------- 1 root root 85805301760 nov 17 13:40 win10-1.qcow2 
-rw------- 1 qemu qemu 42956488704 nov 17 13:42 win10.qcow2

I think there are your windows machines…

Hi
See here: Fix – How To Extend Windows Guest VM Storage in KVM ? – GetLabsDone

Problem fixed. :slight_smile:

I took 3 step to fix this.

First step was with Gparted enlarging the partition, were I have stored the win10 iso and also the partition for the virtual machine. (ext 4)

Second step was going into the kvm settings.

Third step in windows 10, in the virtual machine, add a partition. (it looked like, that after this Windows, was using both partitions as one, the thing I was trying to achieve)

I can’t recall the exact steps in detail, but did not use the windows disk-manager for this.
In windows I went to the messages (warning about an almost full hard disk) and through there selected, add more disk space.

When I tried to do this through the windows disk manager it would not let me. I could add a new partition, but not extent the C drive. :slight_smile:
