Last week I migrated a VM from XEN to Proxmox.
When the VM is idle for two hours, the CPU consumption goes up to 100%. Login and return to normal for a while.

I have two Proxmox 5.2 (one intel and another amd) and in both the same thing happens. Same behavior.
I have tried several combinations of configurations. Virtio HDD, Virtio NIC, IDE, E1000, with balloon, without balloon, etc etc.
I also tried to configure the parameter -T8038.
I also tried to configure boot.init with timer parameter.

I have other 2k3 32 bits servers running without problems. This VM is the only with 2k3 64 bits.
