[9fans] Venti on Qemu?

[9fans] Venti on Qemu?

[Antonin Vecera]

Hi all,

I would like to play a little with Venti...
So I made new installation on Qemu with "fossil+venti" option.
After reboot I saw a strange messages (repeatedly prented onscreen):
...
archive(0, 0x70e5): cannot find block: block label mismatch
labelUnpack 79 73 00037379 73000667 6c656e64
archive(0, 0x74bb): cannot find block: corrupted block label
archWalk 0x74bb failed; ptr is in 0x11e8 offset 49
archWalk 0x11e8 failed; ptr is in 0x11e8 offset 2
archWalk 0xf failed; ptr is in 0xd offset 0
archWalk 0xd failed; ptr is in 0xb offset 0
archWalk 0xb failed; ptr is in 0x5 offset 2
...
Is it possible to run Venti on Qemu?
I just want to look around it but it seems there is a problem.

Hard disk size was 5GB with qcow format, memory 128MB.

this looks like an error one gets when the machine is shutdown
without shuting down fossil and venti gracefully.  are you running
the latest version of venti?  you may want to run venti/checkindex.

It is about 2 weeks old install CD and the error messages are shown
immediately after installation finished and I did reboot.
Maybe Qemu doesn't emulate some function right?
I wonder that nobody has problem with Venti on Qemu. :-)
I will leave it on some day in future...

Hmmm... I made new installation with latest image and it seems OK.

obviously that would fix the problem by overwriting your entire
venti store.  if you're using venti, you need to run fshalt(no man page)
before you kill the emulator.

There is a manual page for fshalt, fshalt(8).

Or it may be that hardly anyone runs venti under qemu?  I
certainly don't.  Given plan9ports I can run venti on a
version of Unix running natively and gain more performance
and flexibility.

I run venti under qemu and xen and kvm and lguest. Works fine.

I never thought about using the linux version. Would be neat if the
venti on plan 9 could be as good as the one on linux, I suppose.

How is the venti for linux better?

I've never tried to configure a venti anywhere but Plan 9, mainly due to the
perception that I wouldn't be able to find my ass with both hands trying to
do so.
