Re: [vbox-dev] high cpu usage after hibernate mode
Try again with 2.1.2. Since 2.1.0 we handle power events to pause running VMs. Huihong Luo wrote: Somtimes, I noted that vbox uses rather high cpu (50%) on windows host.

I've been having this issue since VirtualBox 1.6.2 (IIRC... it's the first version I've ever used), Windows XP host and guest. In my case, as probably happens for Huihong Luo, the processor is a dual-core, so occupancy being 50% actually means a single core is 100% taken by VB. In my case too, the guest still reports 99% idle, as it does before hybernation, except before hybernation the guest really only takes about 3% on average, while as I said it does take 100% of a single core afterwards. The only way to bring the guest actual occupancy back down is to power the virtual machine off (any manner). I still didn't test the XP guest with any VirtualBox 2.x.y version, though. I will soon.

[vbox-dev] high cpu usage after hibernate mode
Somtimes, I noted that vbox uses rather high cpu (50%) on windows host. The steps: run vbox with an XP vm, check host cpu use, which is very low (5%), then hibernate the windows host.
