Hello, all. I have a 3-node Hyperconverged oVirt 4.3.8 cluster running on CentOS 7.7
hosts. I was investigating poor Gluster performance and heard about libgfapi, so I thought
I'd give it a shot. Looking through the documentation, followed by lots of threads and
BZ reports, I've done the following to enable it:
First, I shut down all VMs except the engine. Then...
On the hosts:
1. setsebool -P virt_use_glusterfs on
2. dynamic_ownership=0 in /etc/libvirt/qemu.conf
On the engine VM:
1. engine-config -s LibgfApiSupported=true --cver=4.3
2. systemctl restart ovirt-engine
VMs now fail to launch. Am I doing this correctly? I should also note that the hosts still
have the Gluster domain mounted via FUSE.
Here's a relevant bit from engine.log:
