I installed the Parallels Hypervisor 2.1 build 1670 under Suse 10.0 with
WinXPsp1 as guest operating system. So far I have two problems.

1. When starting the VM, I get the following error:

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

# CONFIG_HPET_RTC_IRQ is not set

linux:~ # hwclock --debug --show

2. When connecting a US B printer or harddrive, I get:

Unable to connect USB device

I tried one suggestion

. Check if an usb-operating group exists in your Linux primary OS.
2. If the group exists:
* Include into this group users who have to have an access to USB
* Proceed to step 5.
3. If the group does not exist:
* Create a group and include into it users who have to have an access to
USB devices.
* In the /etc/fstab file edit the string that mounts the usbfs. Devgid
parameter should contain the identifier of the group created in the
previous step.

usbfs /proc/bus/usb usbfs devgid=<USB gid>,devmode=0664 0 0

This option will of course only work if you have the relevant support
compiled into your kernel.
4. Restart your Linux primary OS.

This resulted in an error in /var/log/boot.msg:

mount: mount point /proc/bus/usb does not exist

Here is the fstab mod:

usbfs /proc/bus/usb usbfs noauto 0 0


usbfs /proc/bus/usb usbfs devgid=1000,devmode=0664 0 0

per the instructions above, after adding USB group which is 1000, I get
the following in the /var/log/boot.msg file:

Without the modification, I do not get the boot.msg error message, but
in either case, I get the Unable to connect USB device error.

Parallels is apparently working on this problem.
