change MemMinMB to 8.

memory.c:24: 	MemMinMB	= 4,		/* minimum physical memory (<=4MB) */

i think this will fix your problem.  i apoligize for missing that.

[9fans] VMWare Fusion on the Mac, can't install Plan 9 ....

[David Leimbach]

... or rather, it installs, but then the installed system will not load.

Whether I pick SCSI or IDE, I get as far as saying I want to log in as
glenda and it just sits there.

Any suggestions as to things I should do post-install, pre-boot to plan9.ini?

Or if there is anything I can do debugger wise to help clear this up?
I'm willing to experiment with it a lot.

[Axel Belinfante]

I tried vmware fusion at home some weeks ago.

I think I succeeded to install plan 9 in it (tryout demo version).
and boot it as well.
What I recall is that the graphics were not redrawn properly,
i.e. correct graphics, but not all of it visible.
Due to this graphics problem I kind of lost interest.

I recall also trying the 1.1beta (or whatever number it had)
but it did not solve the graphics problem.

this was on intel dual core, mac os x 10.4.10.

I'm now at the office so cannot check what I actually accomplished.

Axel.

It draws nicely then.  I can even boot the live Plan 9 CD, but it will
not boot from the installed system for some reason.

If you have an older kernel lying around try booting with it instead
of the latest kernels. i recently did a pull on my parallels
installation and found that 9load does its job, loads the kernel which
then hangs after it prints "entry: somehex". i am unable to
investigate more, but using a 6-month-old kernel works fine. the only
observable difference on the screen is that the printout is "entry:
0xsomehex" ;)

i'll report to geoff if i figure it out.

i am currently working on isolating this problem.  i am seeing
exactly the same thing with my version of 9load.

the problem seems to be a change in load.c

try commenting out the consinit("0", "9600") line.
this is hanging my terminal.

I would if I had a working plan 9 box to do that on :-)

I nearly do, I'm installing it on another real machine...

if 9load is your problem and you can pxe boot,
/n/sources/contrib/quanstro/9pxeloadsb600 may help

Re: [9fans] VMWare Fusion on the Mac, can't install Plan 9 ....

[andrey mirtchovski]

in my case commenting out the consinit line does not fix the problem.
i can still load an older kernel in parallels, but crash when
attempting to load a recent one.

do you have the ability to try
	/n/sources/contrib/quanstro/9loadsb600
?  if so, could you set
	*e820print=y
and see what happens.

what kernel? cpu or terminal?
if it's cpu build a smaller kernel and try that. i ran into this recently
with a pccpuf kernel.

Re: [9fans] VMWare Fusion on the Mac, can't install Plan 9 ....

[andrey mirtchovski]

that does the trick. cpu kernel. the cutoff point seems to be
somewhere above 2.5megs (after decompression).

i don't seem to be able to replicate this with my setup.  could you try to
rebuild 9pcf with /n/sources/contrib/quanstro/l.s to see if this fixes your
problem?  if it does, i'll submit it.

I tried l.s with both consinit() enabled and disabled in 9load with
identical results: booting an older, smaller (2.3mb) kernel is fine,
while a 3.1mb kernel will crash. the only difference after adding the
new l.s to the kernel tree is that the crash now happens after the
Plan 9 text is printed, i.e., we go farther in main() before we hang.

Re: [9fans] VMWare Fusion on the Mac, can't install Plan 9 ....

[andrey mirtchovski]

to add a bit more, now that we have printing enabled: the kablamo
appears to be in meminit().

Re: [9fans] VMWare Fusion on the Mac, can't install Plan 9 ....

[andrey mirtchovski]

finally, i think this is the most detail i can give you. i'll be happy
to take this offline if you think i can be of any more help...

if you look at lowraminit() in memory.c, the second part of the
function calculates x and pa then does a memset(0, pa-x). the values
it obtains for x and pa are:

x=4231168d; pa=4194304d

thus it tries to do a memset of -36864d

compared with a normal, booting kernel, the value of pa is identical,
but x is higher, which is understandable since the kernel is larger,
and x == end... what are the implications after the kernel has grown
beyond pa is left as an exercise to plan9's kernel developers :)

of course i may have overlooked something earlier, but as far as i can
verify, 9load is honest in how it lays the kernel down.

Re: [9fans] VMWare Fusion on the Mac, can't install Plan 9 ....

how much memory do you have and do you know if your (virtual)
machine does an e820 scan?

- erik

Re: [9fans] VMWare Fusion on the Mac, can't install Plan 9 ....

[andrey mirtchovski]

the vm is configured with 512 megs of ram. the code immediately
following lowraminit() is e820init, which works fine (i presume) for
kernels that boot fine. here's the output for a "normal" kernel, a
modified 9pccpuf 2.8 megs in size:

E820: 00000000 0009fc00 memory
E820: 00100000 20000000 memory

plan9.ini has no special config for e820

Disabling the CD within the virtual machine was at one time necessary to
run Plan9 under VMware. It may still be the case. The symptoms are
similar to what you describe.

I did disable the CD, because I'm too lazy to change the boot order.
Still not working but thank you for the response!

thanks. that worked.

turns out I lied about succesull installation though (sorry!)
seems I already gave up before installing,
when the 'boot live cd' gave me the redraw issue.
