Starting windows10 node in CML issue

[CSCO12231061]

Hello,

I have created node and image definition for windows10 node inside CML.

I have also added windows10 qcow2 image in image definition.

Now when I want to start this node I receive error below:

windows0: Launch Queue (E0228 14:29:32.165272 115484 main.go:222] Disk resize failed: qemu-img: warning: Shrinking an image will delete all data beyond the shrunken image's end. Before performing such an operation, make sure there is no important data there. qemu-img: Use the --shrink option to perform a shrink operation.)

 Can anybody advise how to resolve this ?

Hi,

yes, I already checked but didn't find any useful info there.

Did anyone manage to run windows10 qcow2 image in CML ?

If yes can you share node / image definition ?

i have a Linux node running, never tried windows, i will test it later when I get a chance the report back here.

you can post a windows YML file?

have you created a QCOW file or downloaded it from over the internet pre-build?

try to shrink and test it (change the size depending on requirement)

# qemu-img shrink vdisk2.img 30G

[CSCO12231061]

Hello,

I have downloaded windows10 VM from official windows site

and then converted vmdk to qcow2

once qcow2 was imported in CML and node started I received that error

I'll try to shrink the image
