Cpu load high with idle OS/2 guests

Reported by: ts@… Owned by:
Priority: major Component: other
Version: VirtualBox 1.5.4 Keywords:
Cc: Guest type: other
Host type: other


Still exists in 1.5.4:

Host: Ubuntu 7.04 Guests: os/2

Idle Agents still consume 30-40% of a cpu core.

I tried to uninstall almost every BASEDEV/DEVICE driver in the os/2 config.sys and dont start any application in the guest, but still these unused machines consume a lot of CPU power.

I also uninstalled TIMER0.SYS (the os/2 high frequency timer , 1ms resolution) but no change...

  • Summary changed from cpu load high with idle guests to Cpu load high with idle OS/2 guests

Which OS/2 version is that? We haven't seen any issues with MCP2.

comment:3 Changed 10 years ago by ts@…

its os/2 warp 4.5 (convenience package) , here is the syslevel output:

Convenience Package - OS/2 Warp Basisbetriebssystem Version 4.52 Component ID 5639A6101 Type 0C Current CSD Level: XRG4502

What is MCP2? Please give me a note about the environment you used (Host OS , os/2-guest version) i wanna try out here. A copy of your "config.sys" would be great too. thomas

Any advise for me? What is MCP2 , which hardware did you use? Some special settings used?

comment:5 Changed 10 years ago by sandervl73

MCP2 = convenience pack 2. Just a VT-x capable machine; default settings. No changes made to config.sys after install. Works out of the box. Not only for us, but also others.

ok, thanks. We use the same, CP2. And correct, it works without changes out of the box with VT-X = on on our Intel Doublecore Machine.

But an idle machine consumes 30-40% CPU.

Can we close this bug now since you experience a better idle load with VirtualBox 1.6.4?

comment:8 Changed 9 years ago by ts@…

can be closed. With VirtualBox 1.6.4 and Solaris 10u4 CPU load of idle os/2 guest is less than 1% on AMD-Quadcore, AMD-V enabled.
