[9fans] Parallels 5

[9fans] Parallels 5

[Daniel Lyons]

I have a rather old VM that I made under Parallels 3 that seems to work under Parallels 5. I think I installed that one in late 2009 or early 2010. As an experiment, I tried installing the current release under Parallels 5. It installs, and pretty quickly (<5 min), but there are two small issues:

1. ps2intellimouse: scrolling works if you're scrolling down, but if you make the scroll up gesture, the mouse skitters off to the right and really doesn't scroll back up. Anyone seen this or have a tricky solution?

2. Ethernet card is not detected. I am not 100% sure there's nothing different in the configuration, but I've made the plan9.ini look the same in both VMs and still it fails to detect the NE2000 emulated ethernet card. There are also ominous messages about usbd: no hub during bootup that don't happen under the old one.

Is there a boot log somewhere I can examine for messages I may not have seen, or any other debugging information I can go looking for?

I'm downloading 9atom to compare tomorrow.

Thanks,

I have a VM that I created under Parallels 5 and am currently running under 6. It's several months old.

I saw this for the first time today. In my case, scrolling up *also* creates occasional b2 presses. Weird. I haven't used the GUI on Parallels much for two years, so I can't help with when it was introduced.

Ethernet works here (and did under Parallels 5, as well), and I've got nothing in plan9.ini to trick it. You don't see the device at all (not just no data or whatnot)?

/dev/kmesg will give you the console prints so far; /dev/kprint will wait for new ones (and prevent them going to your actual console).

I seem to have gotten my version numbers mixed up. It's Parallels 6 over here as well.

There's no /net/ether0, so I can't run ip/ipconfig to get any further.

I don't see anything interesting there, except that it couldn't initialize usbd. Does usbd work for you?

No device at all. In frustration, I added the following to my plan9.ini:

*noetherprobe=1
ether0=ne2000

This had no effect either. I didn't have to do anything interesting for the old image either, I don't think.

OK, so after so many bytes free, I get this:

cpu0: 2671MHz GenuineIntel Core i5 (cpuid: AX 0x20655 DX 0x1F8BFBFF)
ELCR: 0E80
256M memory: 105M kernel data, 151M user, 574M swap
usbinit...usbd..../boot/usbd: /dev/usb: no hubs

fossil(#S/sdC0/fossil)...version...time...
can't stat /srv/parts.sdXX: '/srv/partfs.sdXX' file does not exist

init: starting /bin/rc

And that's it, nothing particularly interesting. What else can I do to debug this?

Thanks,

according to my sources, parallels is a virtualizer, not an
emulator, so your milage may depend on your hardware.

looks like the vesa emulation barfs on screen blanking.
in parallels.  wierd.

the distribution doesn't have vesa screen blanking and
it is called from interrupt context (mouseclock).

here's a fix for that bug

ladd; diffy -c vgavesa.c
/n/dump/2010/0416/sys/src/9/pc/vgavesa.c:167,173 - vgavesa.c:167,176
  		u.bx = 0x0101;
  	else
  		u.bx = 0x0001;
- 	vbecall(&u);
+ 	if(!waserror()){
+ 		vbecall(&u);
+ 		poperror();
+ 	}
  }

hmm. I'm using parallels 5 on leopard (not snow) and it works just fine with the
std distribution.

please turn off *nodumpstack.  i'll need a full backtrace.
error is being called from an interrupt.

please send the panic message.  would like to fix.

i've turned off mouse accelleration completely in 9atom.  i do
the multplication in the kernel, rather than relying on the
mouse to do it correctly.  i've found that kvms tend to screw
this part of the protocol up.  and really, why go to the trouble
of programming a mouse to do a multiplication?

Also, "echo -n 'accelerated 0' > /dev/mousectl" is required to get the
mouse under control.

I just did a Parallels 5 on Snow Leopard a few days ago. To get anywhere
you have to use a 9atom ISO. I have a terminal instance installed but
haven't had time to do any serious banging on it. I have noticed that
twice now 9pcf has panicked while the VM instance was sitting idle. I
don't remember the panic message, but I should be able to reproduce it
easily enough.
