Suse 10 w/winxp guest /dev/rtc problem (solved)

Read related to this problem, but noting definitive on the solution. One thread had where build 1672 solved problem, but am not able to find that build. If I could, maybe it would fix my problem. Here are the various outputs.

Error output when starting VM

Parallels Workstation encountered a problem with the /dev/rtc device. This may be caused by one of the following reasons: (1) you do not have proper system permissions, (2) the device is not found in your host PC, (3) the device is used by another process. The absence of /dev/rtc device may downgrade VM performance and make internal timers slow.

linux:~ # dmesg |grep -i real

Any suggestions on this or where I can get build 1672 for linux?

Maybe this is a "problem" in Suse and not in Parallels.

What'S the output of

ll /dev/rtc

Maybe the access control is wrong -- as said in the error message?
Pls. check the /etc/permissions.* files too.
 
ll /dev/rtc results in

crw-rw---- 1 root audio 10, 135

What should it be and how do you change it? I looked for that directory in the /etc/permissions file, but did not find it. Found all kinds of other /dev file, but not the rtc.

The file you are looking for under SuSe 10 is:

/etc/udev/rules.d/50-udev.rules

In there do a search for rtc, and add:

MODE="666"

That will set the permissions to appear as:

crw-rw-rw 1 root audio etc etc

And you will no longer get the error.
