Missing images in virt-manager GUI display
 

I want to backup and made extra copies of KVM images.
And thought if I want to transfer a KVM image to another
distribution, I just have to copy it into virt-manager's image folder.
and run it via virt-manager again.

I made a copy of a VM image like so:

NOTE: There are some copies that were deleted using virt-manager, but still shows up in the listing below. WHY?


But my manually copied image (centos7-1500ram-iso-clone1.qcow2) does not show up in virt-manager!

Likewise, some images in above listing did not show up in virt-manager app.

I closed and restart virt-manager mutiple times.
Same missing images occurs.

The images that were installed or cloned by virt-manager shows up.
Those I deleted using virt-manager disappeared from virt-manager's GUI, but seems to still exists in /var/lib/libvirt/images. WHY?

If I am not able to see those copied images, then I cannot start or reconfigure a (K)VM image using virt-manager, obviously ....

So how do I make virt-manager display manually copied (cloned) images
in its /var/lib/libvirt/images directory?

Thank you.

Maybe click on the Refresh "Volume List" button?

@gradinaruvasile:

Where is Refresh "Volume List" in virt-manager?

re
 

try

virsh --connect qemu:///system list

and open again virt manager or

virsh --connect qemu:///system start .img

and open manager again

See the attachment.

@gradinaruvasile:

Your screenshot, it is virt-manager?
My virt-manager do not have those types of GUI.
It looks like this:

I am using Linuxx Mint 18.

What OS is your host?
What is the name of your app?

It's virt-manager 1.4.0 on Debian Testing. The screen i shown is when you click edit->connection details->storage tab.

@end:

Tried all your methods.
None of them seems to work.

replace .img with your centos7-1500ram-iso-clone1.qcow2 or any other

virsh --connect qemu:///system start virsh centos7-1500ram-iso-clone1.qcow2

or try coppy with this command cp -adpR centos7-1500ram-iso-clone1.qcow2

@gradinaruvasile:

i did this:

When I refresh the storage tab, it shows up.
BUT it did not show up in the app's main display area like this:
https://www.virt-manager.org/wp-cont...er-vm-list.png

Then I tried to run it:
It returns error: "Cannot find guest domain centos7-1500ram-iso-clone3"

So it seems I may have to use virt-clone utility like so for it to show up in virt-manager:

Well. You should RTM.A qcow2 file is JUST a virtual hdd imge. It is NOT a virtual machine definition file. Ergo, copying it will NOT create a new virtual machine.

The libvirt vm definition files are in xml format here (this is for Debian, i suppose these are the same for all distros):

All vms that are running under libvirt have a .xml file here.

@gradinaruvasile:

Need elaboration:
What is RTM?

So the only way to clone is to use virt-clone or virt-manager.

That's the way of doing it, yes. You can copy the xml files too but you will have to modify them (change UUIDs/MACs/whatever) and restart the libvirt service.

It's Read The Manual

PS
I wanted to be sarcastic here, but it seems googling RTM might not be as straightforward as i thought for someone not familiar with the term. Also, although wikipedia is the first on the hit list it also provides a long list of meanings - still under the section "Technology and Internet" the first link is "Read the manual" (which redirects to RTFM ...)
