Comment 11 for bug 1783140

Thanks, that makes sense.
So it really seems to be the newer virtio drivers in the guest that triggers it - which is why the move to the HWE kernel

For test systems, I tried to grab a p8 but it failed to install three times in a row. Not sure what is broken atm, so at least for a while I'll rely on you doing the tests.
I totally understand that it is hard (and not recommended by me) to do all the tests with the customer VMs.

If you can do the tests still but have only a short time, just go as far as you can which means just to queens and skip the others in between. From there we can still decide if it is helpful to check the interim versions.

I'll continue trying to get a P8 up with this - maybe I can try one of the new P9 systems as well tomorrow.
Just to check - Is the power system you have a P8/P9/P? ?
