Add compute , then Instances return 500 error. （OperationalError at /instances/，no such column: instances_instance.drbd ）

[smallpize]

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
