[9fans] VMs and current plan9.iso

[9fans] VMs and current plan9.iso

[Jeff Sickel]

Okay... I know this is hashed out on the wiki, and has a long track  
recorded in 9fans, but why is it that we can boot from CD on VMWare  
and then install but then never boot from the installed system?  Yes,

   echo hwaccel off > /dev/vgactl

is required.  Yes it is set, but the first reboot and fossil (&|  
venti) will just hang and nothing happens to get into a usable  
system.  I do need to read up on rdb usage, though that gets a little  
complex w/o an actual serial console.

Is there something that can just be copied over from the plan9.iso  
that would let the system boot and be usable under VMWare?

you forgot the other trick, you either disable the cdrom
or put it in scsi emulation mode.

the nice thing about scsi emulation mode... is it doesn't get nearly  
as far as any of the other options:

^t ^t p

1:
2:
3:
5:
6:  factotum pc	18ed2 dbgpc     18ed2	Pread (Wakeme) ut 0 st 0 bss  
3f000 qpc 0 nl 0 nd 0 lpc f01bd72e pri 10


whereas keeping the drive in ide mode at least gets me to:

init: starting /bin/rc
  1:
...
28:    floppy pc        0 dbgpc      0    Wakeme (Wakeme) ut 0 st 0  
bss 0 qpc 0 nl 0 nd 0 lpc f01bd72e pri 13


hrm.. no idea why a floppy is showing up there, I didn't configure  
that either.

I don't believe SCSI emulation is enough.
If there is no CD in the drive, you have to 
*delete* it from the VM config in order for
Plan 9 not to hang on boot.  Clearly Plan 9 
and VMware disagree about what an empty
CD drive looks like.

Here is my vmx configuration for CDROM

==============

scsi1:0.present = "TRUE"
scsi1:0.fileName = "z:\plan9.iso"
scsi1:0.deviceType = "cdrom-image"
scsi1:0.mode = "persistent"
scsi1:0.startConnected = "FALSE"
