I asked the following question on Superuser about a week ago, but my
question hasn't gained any traction.
I have a Windows 10 VM in VirtualBox (Ubuntu 14 host, VirtualBox 5.0.10
platform). It was originally a Windows 7 virtual machine, and Windows 7 was
fully activated.
A few days ago, I wanted to run some Windows Updates on the Windows 10 VM
to install Threshold 2, but I was told that there wasn't enough disk space.
No problem, I figured I would just resize the disk.... except, that's a
problem. I increased the disk size from 45GB up to 60GB using vboxmanage,
but neither Windows nor gparted running on a Live CD will recognize the
increased storage space.
I read some documentation that indicates there's a bug in VirtualBox that
prevents a guest VM from recognizing increased storage space when snapshots
are present.
I have 2 snapshots (that I don't really care about) of the Windows 10, so I
figured that my snapshots are preventing the virtual machine from seeing
the increased disk size.
When I go to delete the snapshots, I get either of the following results,
depending on which snapshot it is that I'm trying to delete:
- *For the 2nd snapshot / child snapshot - *Error message - Hard disk
{path-to-disk file} has more than one child hard disk (2). *or...*
- *For the "parent" snapshot*, VirtualBox takes a long time acting like
it is merging the differences, and then fails (completely crashes).
Ubuntu's message whenever an application crashes appears with "The
application Oracle VM VirtualBox has closed unexpectedly"
- This is the only line I see in /var/log/syslog: Dec 15 05:52:20
Develop-CENTS kernel: [ 2082.315873] DeleteSnap[6852]: segfault at 20 ip
00000000006e3eab sp 00007f8c97893888 error 4 in VBoxSVC[400000+45b000]
So then I read that if I clone the VM, that would essentially get rid of
the snapshots for me, and then I could increase the disk size on the cloned
VM.
That's what I did, and I then successfully installed Threshold 2.
About a week later, as I was doing some work, I noticed that Windows was
telling me that it wasn't activated. I went into the Settings, and the
message I read indicated was that "Windows 10 isn't activated because the
previous version of Windows was never activated."
Fortunately, I had a backed up copy of the old VM (pre-clone, and
pre-updating to Threshold 2). I turned that back on, and confirmed that
Windows was indeed activated.
So I'm up a creek.
1. Why the heck did Windows 10 lose its activation on the clone that I
created?
2. Can I create a clone without Windows losing its activation?
3. If not, how can I delete these snapshots, which are preventing me
from resizing the hard disk that Windows uses?
