[Qemu-devel] Linux as VirtualBox quest OS with QEMU running Solaris

[Qemu-devel] Linux as VirtualBox quest OS with QEMU running Solaris

[Mateusz Loskot]

Hi,

First, I'm sorry if my question does not belong here. The qemu-devel
says it's "devel", but I can't find any qemu-users mailing list.

I have no experience with QEMU. I've been using x86-only virtualization
software like VirtualBox, VMWare and others.

I need to run Solaris (SPARC) OS and I'd like to do it under QEMU.
Due to hardware constraints, I'm wondering if the following setup
would work at all:

1. Quad-core workstation with 16GB RAM with Windows Vista 64-bit
    as host OS
2. The Windows runs VirtualBox with Linux installed as guest OS.
3. The Linux guest OS runs QEMU
4. QEMU runs Solaris (SPARC)

The Linux guest OS can be either Linux x86-32 or x86-64,
depending which one is recommended and would perform better.

Is this configuration reasonable?
Would it work well?

I have found the "QEMU on Winows" [1] but I'm not sure if this is an 
official project and if it's "production ready".
I need to have fairly stable environment for building and
testing software on SPARC architecture.

I'd appreciate any help and sugestions.

I have seen it once but could not find it either when searching for a
qemu mailing list to subscribe to.

If you can find a build of recent qemu for Windows it should preform
as well as qemu on Linux for emulating a SPARC (= different
architecture).

Adding another layer of virtualization is going to hurt performance at
least and could potentially introduce additional issues.

However, the device emulation is different on Windows compared to
Linux so you may find that networking and screen emulation works
differently compared to Linux.

I will try to find or build it.

Yes, that's what I am worried about.

I see. Actually, I do not need to access Solaris with any GUI, text mode 
will do well.


Thanks for the hints.

Using a native windows version of qemu would be more reasonable.
There are no precompiled windows binaries of current qemu,
so you will have to compile them yourself (which is not difficult
once you have the correct mingw environment).

The setup which you proposed might work in theory, but will be
less performant (if it works).

OK, makes sense to me.

Great. I think I should be able to do that.

Which version of QEMU source code should I grab?
Latest stable or development version from Git repo?

I suggest using QEMU git master. You could try the binaries
from my website: http://www.weilnetz.de/qemu/

Stefan,

Thank you very much!
So far, I have tried to use versions of QEMU from Qemu Manager 0.7
as well as QEMU 0.13 from
http://homepage3.nifty.com/takeda-toshiya/
but without any luck. I suppose it's because these versions do not
have most recent OpenBIOS usable with SPARC.

I quickly tried your binaries and it looks I have to run them from 
within MSYS environment, isn't it?
I'm getting runtime error reporting msys-z.dll is missing.


I tried to find instructions on building QEMU with MinGW.
No luck. Is there anything available?

If you need Solaris, OpenBIOS is currently not your choice. Have to
use an OBP blob.

I understand.

> Have to use an OBP blob.

Where can I find instructions on how to use it?

Actually, I don't need Solaris but SPARC.
So, even Linux for SPARC would do for me.

I tried Debian 4.0 (etch) and Debian 5.0 (lenny) but with no luck.
I think I confused the 32 vs 64 bit and SPARC flavors.

32 bit Debian 4.0 should work out of the box, also with OpenBIOS. The
5.0 exists only for 64 bit machines, so it can not be booted yet.

OK, then I will stick to the Linux distribution for 32-bit SPARC
and see if it works for me.

> The 5.0 exists only for 64 bit machines, so it can not be booted yet.

Trying to understand it better...there is limitation in QEMU,
so it does not boot 64-bit SPARC yet, right?


Thanks for clarifying it.

If anyone is curious, I did a quick test on my over-engineered
configuration with Windows Vista running VirtualBox with Ubuntu 64-bit
as guest system running QEMU which is supposed to run Debian Etch 32-bit 
SPARC.

I run:

$ qemu-img create -f qcow hda.img 20G
$ qemu-system-sparc -m 256 -hda hda.img -cdrom 
/home/mloskot/software/debian/debian-40r8-sparc-netinst.iso -boot d 
-localtime

and QEMU window appears but it remains black all the time.
The VirtualBox CPU is running 100%.
I can issue CTRL+ALT+{1|2|3} to switch QEMU consoles, but nothing 
related to Debian booting appears.

Here is screenshot:

http://www.flickr.com/photos/mloskot/5348626557/

I'm wondering if this is related to the VirtualBox+Linux host proxy.

Try -nographic . Also it's interesting to know whether you see
something when you start qemu-system-sparc without any command line
options.

I can run NetBSD sparc install CD just fine.

It supports sparc32 in the latest release.

Thanks. Great, I'll try.

One of the problems I found with Debian Etch is the package repositories 
are no longer supported and the installer
can easily mess with those for Lenny.
The only solution is to have all CDs for Etch available and run complete 
offline installation.

I guess the NetBSD option is more up to date here.

OpenBSD should also work.

I have tried the recent NetBSD and it boots without problems,
however I can't configure networking to install via FTP/HTTP.
Strangely, I don't get question about DHCP.

I think it's unrelated to SPARC support discussed in this thread,
so I posted my full story to the QEMU forum:

http://qemu-forum.ipi.fi/viewtopic.php?f=14&t=5949

Yes, that's probably an issue with the sparc installer script.

However, the sparccd has all the sets so you can easily install from the CD.

Once installed you can set up dhclient.

Thanks for the hint.
Indeed, I managed to install the base system from CD and boot from QEMU 
image. I performed post-install configuration according to the NetBSD 
guide and I have dhclient=YET in /etc/rc.conf.
The only problem I find is that I'm unable to configure any
other networking than the user mode with QEMU network 10.0.2.0.

I'm still using QEMU 0.13 binaries installed using Qemu Manager 0.7.

I tried to play with -nic option and the only model supported by 
qemu-system-sparc is lance (iface=le0).
I tried to pass both -net nic -net user with hope to get two
network interfaces so I can setup one to obtain IP from my external 
DHCP, no luck.

I have read through manual and Web resoruces, but I feel I'm still 
missing something something, in particular, I don't understand how to 
make the iface connecting to my external DHCP instead of QEMU's.

Certainly, I mean, dhclient=YES

Learned about the networking better and managed to
connect (SSH) to my emulated NetBSD installation from host system 
(Windows Vista) thanks to ports redirection as explained here:

http://en.wikibooks.org/wiki/QEMU/Networking

I should have read the docs more carefully.

There are some instructions in qemu-doc.html.
The main problem is getting a really complete MinGW environment.
Then running

     ./configure
     make
     make install

should be all you need.

I grabbed the recent version from http://www.weilnetz.de/qemu/2011-01-10/
and the three DLLs from the http://www.weilnetz.de/qemu/
but the msys-z.dll is still reported as missing.

I managed to run your binaries inside MSYS shell and the msys-z.dll 
complain disappeared. However, when I try to use qmake-img, funny things
happen. It looks the size parameter is not parsed properly.

For example:

- these commands work

qemu-img.exe create hda.img 10M
qemu-img.exe create hda.img 2000M

- these don't work

qemu-img.exe create hda.img 10G
qemu-img.exe create hda.img 2500M


Screenshot attached.

Hi,

this is a regression in current QEMU: it cannot create disk images 
larger than 2^31 B (2 GiB).
It's discussed at 
http://lists.nongnu.org/archive/html/qemu-devel/2011-01/msg00357.html.

A new version for MinGW now includes a patch which should fix that 
regression,
see http://www.weilnetz.de/qemu/2011-01-10/ (available in a few minutes).

I also added the missing http://www.weilnetz.de/qemu/msys-z.dll.

Kind regards,
Stefan Weil

Thanks for these Windows builds.

I don't run qemu on Windows right now but I used it in the past and
they may come handy again.

Out of curiosity, do you build on Windows or do you cross-compile on
Linux or somesuch?

Thanks

Michal

The above versions were cross-built on Debian Linux,
but I also run native builds on Windows.

Sparc32 Solaris can run with recent QEMU:

Sparc64 is not ready yet.

Someone should step up as Win32 maintainer, also making Windows builds
available.

Good to know. Though, I may be old, but I prefer mailing list
than Web-based forums.

Anyway, if I understand it well, there is nothing wrong with posting
non-development questions to qmenu-devel, is it?

Fantastic!

I can stick to 32-bit.

I can't help, I regret.

Thanks for help!

Quick summary of results with the original idea:

So, instead of Solaris I installed NetBSD 5.1/SPARC under QEMU.
I performed the installation using QEMU 0.13 on Windows Vista.

Next, I copied .img file from Vista to Linux Ubuntu (64-bit)
I also cloned QEMU Git repo. built QEMU from source and installed.
Finally, I successfully booted the NetBSD system on Linux guest
running under VirtualBox hosted on Windows Vista:

The idea seems to work.

I haven't solved the networking problem with configuring the only 
existing iface=le0 with external DHCP, but that's another story.

Folks, thanks for help!
