I do not have IO ACPI enabled. Host is FC12 x86. Guest is windows XP Pro installation CD. So I am trying to install it on a physical vdk. Output of top shows almost 90% of cpu being used by VB. top - 00:01:47 up 1 day, 11:52, 5 users, load average: 1.39, 1.95, 2.19 Tasks: 181 total, 1 running, 175 sleeping, 5 stopped, 0 zombie Cpu(s): 17.1%us, 82.2%sy, 0.0%ni, 0.0%id, 0.0%wa, 0.0%hi, 0.7%si, 0.0%st Mem: 2062360k total, 1906572k used, 155788k free, 189068k buffers Swap: 8385924k total, 11788k used, 8374136k free, 477024k cached PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 12712 jd 20 0 1070m 779m 48m S 88.3 38.7 5:15.35 VirtualBox 5815 jd 20 0 671m 113m 26m S 6.6 5.6 41:03.50 java 1616 root 20 0 388m 45m 9484 S 2.0 2.2 71:31.16 Xorg 11202 jd 20 0 2768 1024 768 R 0.7 0.0 2:09.64 top 1852 jd 20 0 114m 9428 6988 S 0.3 0.5 1:15.76 gnome-settings- I was hoping that someone has some way of limiting VB to use no more than a user specified percentage of CPU. Is this possible? Cheers, JD ------------------------------------------------------------------------------ Download Intel® Parallel Studio Eval Try the new software tools for yourself.
