After upgrade, I noticed that CPU graphs in virt-manager for qemu guets are empty. I am running VMs as a regular user (connection URL is qemu:///session).
I had to install python-cairo to make graphs visible at all. Now, I can get network, memory and disk graphs to work, but "CPU Usage" and "Host CPU Usage" are still empty - graph is visible, but contains no data.
What could be the reason?
Polling of CPU usage in Preferences is enabled.
Thanks!

This is due to a missing dependency python-cairo. It's already being tracked here: https://bugs.archlinux.org/task/60477

Thanks, but I already installed python-cairo as mentioned above. The graphs are working, only the CPU and memory graphs contain no data. Any idea?

Looks like the problem is not with graphs, but with getting the data for CPU stats. If I run the corresponding virsh command, I get this:
$ virsh cpu-stats mydomain
error: Failed to retrieve CPU statistics for domain 'mydomain'
error: Requested operation is not valid: cgroup CPUACCT controller is not mounted
How can I fix it?
(Note: this was already working in the past before I updated the system, so it seems to be a regression.)

I'm having the same issue on Fedora 29.
When using gnome-boxes in can see the CPU graph. In virt-manager, the CPU graph isn't shown.
How can this be fixed?
