Hi, I have been using proxmox 4.4 for 1.5 months till now. And have used 2.4 for almost 6 years without any problem.
Last two days the virtual machines started using high CPU from 10% average to 100%... The php requests on one VM got quite slow. Before this happened I did not install / update / vm modifications on the host.
The main symptom is slow CPU processing on VM and high cpu load on guest, with almost no thread...
I tested all the hardware and I didn't found nothing wrong, also upgraded to the last proxmox version (kernel, ...)
Anyone knows what might be happening?
