1.2.7. Uninstallation¶

Stop the Virtual Accelerator service¶

Make sure Virtual Accelerator is no longer running, following the documentation:
```
# systemctl stop virtual-accelerator.target
```
Disable Virtual Accelerator from the list of services:
```
# systemctl disable virtual-accelerator.target
```

Remove the QuickAssist add-on 1:

# yum remove -y virtual-accelerator-addon-qat

Remove the KPIs add-on:

# yum  remove -y virtual-accelerator-addon-kpis

If you enabled OpenStack support, remove it now:
```
# yum remove -y 6wind-openstack-extensions
```

Uninstall the Virtual Accelerator repository:

# PRODUCT=virtual-accelerator
# DISTRIB=redhat-8
# PKG=6wind-${PRODUCT}-${DISTRIB}-repository
# yum autoremove -y $PKG

Note

Change the PRODUCT to virtual-accelerator-ipsec for Virtual Accelerator IPsec.

Uninstall the meta-package (which will remove most dependencies):
```
# yum autoremove -y $PRODUCT
```
If you enabled OpenStack, reinstall the latest openvswitch package (previously overridden by Virtual Accelerator):
```
# yum upgrade -y openvswitch
```
Warning

Some configuration files are conflicting between 6WIND version and the official one. Use files from the package maintainer.
If you enabled OpenStack, remove 6WIND packages that depended on openvswitch and were thus not removed when cleaning the Virtual Accelerator meta-package:
```
# yum autoremove -y
```

Optionally, you may want to get back an older version of libvirt and QEMU than what you installed through this documentation:

Start by stopping the libvirt service:
```
# systemctl stop libvirtd
```
Remove virtualization tools current versions:
```
# yum remove -y qemu-kvm-rhev libvirt libvirt-python
```
Warning

Some packages depend on libvirt and QEMU (opentack-nova-compute for instance). Make sure to reinstall those after removing 6WIND packages.
Remove the 6WIND repository for early technology access builds:
```
# yum remove -y 6wind-public
```

Reinstall the official virtualization tools:

# yum install -y qemu-kvm-rhev libvirt libvirt-python
