Errors starting PW 2.2

When staring Parallels vm I get a couple of pop up errors. Host is Suse 10.1 and Winxp is the guest.
The first one is :
"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".

The second one is:
"Unable to open device/file lp0".

I wonder how to correct these.

Hi Danorske. First of all, /dev/rtc refers to the Real Time Clock device. So you can see why Parallels tells you about possible problems if it's not able to access said device.
It's probably just a matter of adding yourself to the group that controls that device. Or maybe changing its permissions (I'd look for the group solution first).

Second, lp0 refers to the parallel port. Unless you're planning on doing some work with it, it's just an annoyance.
 
Thanks David,
Got the RTC to work [not pop up]. went to it as root and made it readable by root. took care of it. :)

lp0 is for my printer. Now to get it to work.

Hmmm same here (Ubuntu dapper) but I don't see any problems when firing up parallels.
You can try these two:

1) Go to System->Administration->Users and Groups->Groups->Show all users and groups. There select the group lp and add yourself to that group.
2) Change the permissions of the /dev/lp file. chmod 555 /dev/lp (as root).

Where did you find /dev/rtc? I have done a search in suse 10.1 but can't find it.

David,
I did this it did NOT work. In fact Now I can't even print from the host. :eek: How do I change it back?

I went to yast/software management and uninstalled everything to do with HP. except the hplip-hpijs. cause when I tried it had a bunch of dependancies stuff and I didn't know what to do so I left it alone. rebooted and now suse prints.
Now just have to figure out how to make Winxp on Parallels VM to print.
Regards
Ron

Oh, yea, "even easier". Thats easy for you to say. :=)
I've never been able to get anything to network. {XP to Linspire}. I've looked at Samba and I guess my problem is understanding the words [terminology] used.
In other words as far as networking is concerned I don't know what to do.
Thanks,
Ron
 
.
Just go to Yast, Network Services, Samba Server, and make sure that "all printers" and "printer drivers" are both enalbled. Click finish. Then in XPoo, go to Control Panel, Printers, and "add printer". Browse for a network printer which will appear under the hostname of your machine. If you have not supplied a host name, then it will appear as "linux.site". Double click the hostname to show printers on that machine. Select the printer and complete the steps for setup.
