thanks @mmenaz for reply. about not starting - my bad - had to change the boot order to start installing the OS. about random VMs crash - still the same KVM: entry failed, hardware error 0x5 in logs. https://forum.proxmox.com/threads/vm-ubuntu-server-random-running-issues.81483/#post-360650...

during 20 min. just OS(ubuntu) on VM's. No actions taken. just looking into the logs.

thanks guys for all the ideas. Special thanks @tburger for https://forum.proxmox.com/threads/cpu-cores-and-threads.65923/ was fallowing the recommendations from Option 1 the same issue, very disappointed.

Thanks @tburger

thanks @tburger for the details, very helpful. If you don't mind, lets simulate a situation. Examples are very useful . 1 socket, 14 pCPU(28 vCPU) - 2.40 GHz. Requirements: build a kubernetes cluster. lets say 3 master nodes and 4 workers. a worker node will have, lets say a max of 20...

hi @tburger Guest

one more question @tburger please about the same: statements: 1vCPU = 1 Core Stick with the physical cores you have(physical count cores - not hyper-threading) the CPU sum of all running VMs should be <= number of physical cores? is that right?

Another interesting situation: I have 4 VMs(Ubuntu) a(1cpu), b(1cpu), c(2cpu), d(2cpu) - all good. Ive create VM nr. 5 - e - 8CPU. got Internal error for VM d and e. KVM: entry failed, hardware error 0x5

good to know @tburger, thanks! any good practice recommendations - please share it here please. Any idea's why Im getting this fail after executing virt-host-validate? (if I understand correctly, all the lines should be pass)

Thanks for reply. Not sure if this is the root cause or not... Now I create VM's allocating 1-2 cores(ONLY).. before I was adding 28(max I have) I hare 3 VMs green. installing 4th VM. was running virt-host-validate and getting this:

root@orion:~# cat /sys/module/kvm_intel/parameters/nested N root@orion:~# had it enabled before. now Im getting straight only KVM: entry failed, hardware error 0x5
