If you need to get a certain file from a snapshot (and not the entire snapshot), you can access the files with:

ssh to the antsle (antsle, not antlet)

cd /antlets/{antletname}/.zfs/snapshot/{snapshotname}

Then copy whatever files you need to their original locations.

 

But to restore the whole antlet, in Antman, you click on the antlet, then the snapshots tab.  Then there's a menu at the far right to restore that snapshot.

*Note that if you want to restore to a snapshot older than the latest, it will delete the newer snapshots (newer than the one you're restoring to)

Thanks for the reply, but .zfs isn't there. I know there were 2 snapshots made, one from yesterday morning.

root@myantsle:/ # ls -al /antlets/pizza
total 7
drwxr-xr-x 2 root root 3 Mar 24 17:24 .
drwxr-xr-x 44 root root 4096 Mar 24 18:42 ..
-rw-r--r-- 1 root root 3119 Mar 24 16:04 antlet-libvirt.xml

It's invisible (even ls -la doesn't show it).

Try typing:

cd /antlets/pizza/.zfs

Then

ls -l

I wasn't expecting it to be hidden, thanks! Files were copied as recommended, but when the virtual drive was deleted, the Antlet was no longer listed in antMan.

"But to restore the whole antlet, in Antman, you click on the antlet, then the snapshots tab.  Then there's a menu at the far right to restore that snapshot."

So your comment on the next step, can't be performed.

Hi @akak01000101,

You can also try cloning the antlet from the snapshot. Then take move or copy the drive back, and optionally delete the clone.

I have this now below, but again antMan doesn't see it. What shell commands can I use to get antMan to see it. I tried restarting antMan thinking it would re-scan everything. That didn't work.

root@myantsle:/ # ls -l /antlets/pizza

@akak01000101

If you manually moved it, you need to update the domain's XML with the `virsh edit pizza` command, then add the following XML below the `<emulator>` tag:

```
<disk type='file' device='disk'>
<driver name='qemu' type='qcow2'/>
<source file='/antlets/pizza/Ubuntu-18.04.kvm.qcow2'/>
<target dev='vda' bus='virtio'/>
</disk>
```

Just to be clear, should look like this:
```
<emulator>...</emulator>
<disk type='file' device='disk'>
...
</disk>
```

[SOLVED] I'm up and running. Thanks guys!

1. cd /antlets/{antletname}/.zfs/snapshot/{snapshotname};
2. cp * /antlets/[antletname}/
3. virsh edit {antletname}

<emulator>...</emulator>
<disk type='file' device='disk'>
     <driver name='qemu' type='qcow2'/>
     <source file='/antlets/{antletname}/{OS_template}.{type}.qcow2'/>
      <target dev='vda' bus='virtio'/>
</disk>

4. The antlet will boot at this point.

BUT... I also have a USB drive attached. I discovered the Device number in Antman changed, and the Antlet would still would not boot. It would give an error "Internal Error: Did not find USB device BUS:2  Device:4" when I tried to start the Antlet.

So in the virsh edit, I also removed the following and just re-added the USB drive that was displayed in Antman.

<hostdev mode='subsystem' type='usb' managed='yes'>
<source>
<address bus='1' device='4'/>
</source>
<address type='usb' bus='0' port='2'/>
</hostdev>

Antlet boots and the USB drive mounts just fine!

Thanks again.
