Can Not Exceed 60 Concurrent Sessions (3.1.4 and 3.2.8)

Reported by: Muenchc Owned by:

Host type: Windows

Description

When running > 60 guest sessions in Windows 2003 (x86, DL580 G5 VT Enabled, 8 core, 64Gb memory) the sessions will never "power off". When we go to power off a guest session it will just sit in a italiced "power off/powering off" state where vboxmanage controlvm *vmname* poweroff or acpishutdown will not affect it.This occured in version 3.1.4 so we decided to upgrade to 3.2.8 where the issue is still present. If we are running < 60 sessions these guests will spin up and down just fine. Attached is a VM in this state

60 sessions in parallel?

comment:2 Changed 4 years ago by Muenchc

That is correct. All of them in a vboxheadless state (60 vboxheadless.exe processes running in parallel)

This is certainly less than expected, on 32bit OSes one should be able to run 127 VMs at a time. On 64bit OSes the limit is 1023.

Replying to klaus:

My thoughts as well. Trying to achieve 100 but right now this is a huge road block
