Subject: [ovirt-users] Huge increase of CPU load on hosted engine VM after upgrade to
4.3.8 and cluster compatibility version

I have upgraded yesterday one of our ovirt environments from 4.2.8 to 4.3.8.
We have a hosted engine, 25 hosts and about 150 VMs running there.
After upgrading the cluster compatibility version from 4.2 to 4.3, I have seen a huge
increase of CPU load on the engine VM.
The engine had 4 cores (16GB mem) and never had load issues, but after the upgrade, the
system has a load of 6 and more. I have increased the CPUs to 8, because working in the UI
I have noticed, that the load always increase, when I load the VM UI tab, where now all
VMs have the orange triangle with pending changes: Custom compatibility version
The problem I have, is, that I can't reboot now all VMs, maybe in the next 3 or 4
Working now with the UI is quite problematic, because of the slowness.
The engine VM was already rebooted, but didn't solve the problem.
What logs do you need and is there a workaround available? I have some more oVirt
environments to upgrade, all with even more VMs.
