The problem is probably because VMWare uses the processor TSC counter |
| 17 |
for timing, the rate of which varies with the processor frequency. |
| 18 |
|
| 19 |
The following works for me on a pentium-m 2.13ghz system: |
| 20 |
|
| 21 |
1. Add "processor.max_cstate=1" to your kernel boot options. |
| 22 |
2. If you are running cpufreqd, stop it with "/etc/init.d/cpufreqd stop" |
| 23 |
3. Do "echo performance |
| 24 |
>/sys/devices/system/cpu/cpu0/cpufreq/scaling_governor" |
| 25 |
4. Run VMWare. |
| 26 |
|
| 27 |
When you are done with VMWare, you can restart cpufreqd to get the |
| 28 |
frequency scaling back. |
| 29 |
|
| 30 |
Actually, #2 isn't strictly necessary, but you have to add a rule to |
| 31 |
/etc/cpufreqd.conf to use the performance governor when VMWare is being |
| 32 |
run. For example, mine contains the following: |
| 33 |
|
| 34 |
... |
| 35 |
[Profile] |
| 36 |
name=Performance High |
| 37 |
minfreq=100% |
| 38 |
maxfreq=100% |
| 39 |
policy=performance |
| 40 |
[/Profile] |
| 41 |
... |
| 42 |
## |
| 43 |
# VMWare |
| 44 |
[Rule] |
| 45 |
name=VMWare |
| 46 |
programs=vmware-vmx |
| 47 |
battery_interval=0-100 |
| 48 |
profile=Performance High |
| 49 |
[/Rule] |
| 50 |
|
| 51 |
The above rule is the very first rule in my configuration. With this, I |
| 52 |
do not have to do steps 2 or 3 above. |
