I do have the DVD connected to the virutal machine.

In that case I would disconnect it unless you need it. Or try loading some CD disc to the drive... it could be that IDE driver uses some other call than SCSI driver to find whether device is ready, and on IDE this call is fast, while in the SCSI/SATA driver it is slow... It was seen in the past on Windows hosts as guest hiccuping every two seconds for second or so... Especially if guest are Windows, with insert media notification polling drive every two seconds...

hi,

I have exactly the same problem (same computer), both with VMware Workstation v5 and v5.5 beta.
Unfortunately, disconnecting the DVD doesn't make any difference.

Ubuntu as well.

With exactly the same system, VMWare is running fine on my desktop computer (AMD XP 2600+, Ubuntu breezy, kernel 2.6.12), so obviously the problem comes from the Inspiron hardware.

I tried to compile a 2.6.14 kernel and made sure that in /usr/src/linux/include/linux/libata.h:
#undef ATA_ENABLE_ATAPI
#undef ATA_ENABLE_PATA
where not enable, but it didn't change anything...

I just tried again with a newly compiled kernel (2.6.12, the one coming with Ubuntu, without applying any patches) and with VMWare 5.5 RC2, and I still have the same problem (The host OS (windows XP) takes more than 5 min to shutdown for example).

If anybody find a way to compile a kernel allowing good performances with VMWare, I am really interested. Even if it means getting poor performances with the DVD player, I really don't care...

In that case you are again not running at 2GHz with 'performance' governor, but at variable (~1GHz) frequency again...

Hm. To reiterate, you still use WS5.0, and when you are using your VM, last line about host clock frequency says that it was switched from ??? (probably 18) to 83 Hz, yes? And you have disconnected CDROM/floppy/USB from guest?

In that case I have no idea. 83Hz is quite low value and you should not have any problems. Maybe that BIOS in your laptop always slows down processor, regardless of cpufreq setting. I cannot think of any other reason. Can you try running 'x86info --mhz', whether it will report 2GHz or no?
