How to
Integrate vProtect dashboard plugin to OpenStack (LXC)
example:
list snapshot:
[root@kvm-c8 ~]# virsh snapshot-list alpine_c8
Name Creation Time State
------------------------------------------------------------
vProtect-157e97b2-aec8-4e6b-8181-0022427e92e2 2020-07-07 13:48:47 +0200 disk-snapshot
vProtect-aa2878cb-288c-4ac9-b1ec-5a328f22a6f5 2020-07-07 14:03:07 +0200 disk-snapshot
vProtect-b534b5dd-9480-4336-bf17-81a4308dfb6f 2020-07-07 14:42:07 +0200 disk-snapshot
vProtect-f05555c7-a881-4b18-b5b2-f4a84eba71c6 2020-07-07 15:48:27 +0200 disk-snapshot
remove snapshot:
[root@kvm-c8 ~]# virsh snapshot-delete --domain alpine_c8 --snapshotname vProtect-f05555c7-a881-4b18-b5b2-f4a84eba71c6
error: Failed to delete snapshot vProtect-f05555c7-a881-4b18-b5b2-f4a84eba71c6
error: unsupported configuration: deletion of 1 external disk snapshots not supported yet
Solution
Check your VM, it must be running:
Id Name State
----------------------------------------------------
1 alpine_c8 running
List all existing snapshot for your VM:
[root@kvm-c8 ~]# virsh snapshot-list alpine_c8
Name Creation Time State
------------------------------------------------------------

In our example we have all disk in the same chain.
Get simple name of disks:
[root@kvm-c8 ~]# virsh domblklist alpine_c8
Target Source
------------------------------------------------
hda /var/lib/libvirt/images/alpinelinux3.8.qcow2-vProtect-f05555c7-a881-4b18-b5b2-f4a84eba71c6
hdb -
Merge disk, that process can take a while, depend of disk size:
[root@kvm-c8 ~]# virsh blockcommit alpine_c8 hda --verbose --pivot --active
Block commit: [100 %]
Successfully pivoted
When the disk is merged you can check it is single file:
[root@kvm-c8 ~]# virsh domblklist alpine_c8
Target Source
------------------------------------------------
hda /var/lib/libvirt/images/alpinelinux3.8.qcow2
hdb -
Next remove snapshot information from VM:
[root@kvm-c8 ~]# virsh snapshot-delete --children --domain alpine_c8 --snapshotname vProtect-157e97b2-aec8-4e6b-8181-0022427e92e2 --metadata
Domain snapshot vProtect-157e97b2-aec8-4e6b-8181-0022427e92e2 deleted
When you check again files of disks on file system you see active is "/var/lib/libvirt/images/alpinelinux3.8.qcow2", and rest images still on filesystem:
[root@kvm-c8 ~]# ll /var/lib/libvirt/images/alpinelinux3.8.qcow2*
-rw-------. 1 qemu qemu 1611071488 Jul 8 13:48 /var/lib/libvirt/images/alpinelinux3.8.qcow2

Remove not require files from filesystem:
[root@kvm-c8 ~]# rm /var/lib/libvirt/images/alpinelinux3.8.qcow2-vProtect-157e97b2-aec8-4e6b-8181-0022427e92e2 /var/lib/libvirt/images/alpinelinux3.8.qcow2-vProtect-aa2878cb-288c-4ac9-b1ec-5a328f22a6f5 /var/lib/libvirt/images/alpinelinux3.8.qcow2-vProtect-b534b5dd-9480-4336-bf17-81a4308dfb6f /var/lib/libvirt/images/alpinelinux3.8.qcow2-vProtect-f05555c7-a881-4b18-b5b2-f4a84eba71c6
