Hi there,

A few weeks ago I created a windows10 vm in my EVE, made changes to the image and then merged the snapshot back into the base windows10 image - all went well, I created a new windows10 node in my lab, started it up and all my changes were now in the new base image.

Problem, now I can no longer successfully merge the snapshot with the base, "qemu-img commit" give me a "Co-routine re-entered recursively Aborted" when trying to commit the snapshot to the rebased image. Here are my exact steps, maybe I've missed something?

1. Copy windows10 image to temp working directory
mkdir /root/win10-work/
cd /root/win10-work
cp /opt/unetlab/addons/qemu/win-10-nosparse/virtioa.qcow2 virtioa-work.qcow2
2. Add windows10 node to lab
3. Make changes to windows10 node and shutdown node
4. Check windows10 snapshot with qemu-info and see that base is correct image in /opt/unetlab/addons/qemu/win-10-nosparse - it is
/opt/qemu/bin/qemu-img info /opt/unetlab/tmp/0/03d0fb94-bb4e-4b0b-845d-51744497e47f/2/virtioa.qcow2
"image: virtioa.qcow2
file format: qcow2
virtual size: 20G (21474836480 bytes)
disk size: 2.7G
cluster_size: 65536
backing file: /opt/unetlab/addons/qemu/win-10-nosparse/virtioa.qcow2
Format specific information:
compat: 1.1
lazy refcounts: false
refcount bits: 16
corrupt: false
5. Rebase the snapshot:
/opt/qemu/bin/qemu-img rebase -b /root/win10-work/virtioa-work.qcow2 /opt/unetlab/tmp/0/03d0fb94-bb4e-4b0b-845d-51744497e47f/2/virtioa.qcow2

6. Verify that /root/win10-work/virtioa-work.qcow2 is the new base for snapshot - using qemu-info on snapahot image - it is
7. Merge snapshot into new base:
/opt/qemu/bin/qemu-img commit /root/win10-work/virtioa-work.qcow2 /opt/unetlab/tmp/0/03d0fb94-bb4e-4b0b-845d-51744497e47f/2/virtioa.qcow2


Get error:
"Co-routine re-entered recursively
Aborted"

This used to work about a month ago, but no t working now. Stange thing is that it works on my other images, just doesn't work on my WIndows images.

Thanks in advance.

I dont know mate,

but I always used this how to and all works, with any Win image.
W10, s2012, S2016 as well

Thanks UD, but the document in your link does not address merging the snapshot with the base image. I have no problem creating and running the Windows image, my problem is not being able to merge snapshot changes to the base image to make those snapshot changes persistent.... it used to work about a month ago

instead of 'rebase', use convert to create a new disk image

so create a new folder for this new updated image and use the same procedure ( the one to create an image from scratch )

mkdir /opt/unetlab/addons/qemu/win-mynewimage/

and from the tmp folder where you got the modified image to rebase:
E.

p14 in how to marked as important how to send snapshot to base image...

Thanks, I'll try this method and see how it works out!

That works! Thank you.
