Hi,

Recently I've set up a VM with 8 virtual cpus. My hardware is also 8-way cpu with hyperthreading which makes 16CPUs visible by proxmox.

I guess I've run into deadlock issues with this vm, as it freezes sometimes. Top shows that it freezes on futex_wait syscall, which indicates process communication problems within VM.

However, I'm not sure about this.

How many CPUs do you have configured per guest? Have you ran across similar issues.
