[9fans] Problem installing to VM

[Hans Stimer]

I've tried 3 different VMs (VirtualBox, VMWare, QEMU), but I'm getting the same install error each time.

The Live CD seems to die with:

kfs 4: suicide: sys: trap: fault read addr=0x39000 pc=0x00038fa0

Im using this iso:

http://plan9.bell-labs.com/plan9/download/plan9.iso.bz2

Should I be using something else?

assuming that pc's not bogus and there isn't anything else afoot, like a broken
image (i don't think my kfs neé bzfs matches up and the version in the dist
kernel is stripped), 0x39000 is the next page after
the current pc, so unless the bss is 0 bytes, 0x39000 must be a valid page.
so one assumes there is some other reason for a fault. either there is a bug,
or perhaps a memory allocation failure for page tables caught the kernel
out. i would try bumping the image memory to at least 512mb.

good luck.

Bumping the RAM to 1GB did nothing, but switching to the 7/3 iso worked. 

Thanks!

It looks like an issue with the latest CD image.

You could try with an older image from http://mirror.9grid.fr/,
until the problem is fixed.

The one from 2013-07-03 seems to work fine.

Thanks for reporting.
