Original GitHub issue: https://github.com/retspen/webvirtcloud/issues/529

Create the website as normal，the login is successful。
When I create a compute node through ssh, I switch to Instances and report a 500 error.
I use Kylin V10 system (same as openeuler 20.03TLS) as computing node.
Compiled against the library: libvirt 6.2.0
Libraries used: libvirt 6.2.0
API used: QEMU 6.2.0
Run the hypervisor: QEMU 4.1.0
but I don't think it's the client compute node's problem. I try to create a user, but also an error is reported. After logging in again, the user information already exists，and use the user login, change to Instances, also error（no such column: instances_instance.drbd）.
I use kenlee/webvirtcloud-docker create website can add compute and change to Instance successfully.

you can always run these commands, it does not breaks. may some scripts failed. run;
# Go to Installation Directory
cd /srv/webvirtcloud
source venv/bin/activate
pip3 install -U -r conf/requirements.txt 
python3 manage.py makemigrations
python3 manage.py migrate

I remove the db.sqlite3 file, and run again, this problem solved.
Thanks.
