ocaml parallel build errors

ocaml parallel build errors

[Christoph Egger]

Hi!

On a clean source tree, I get an ocaml build error
with gmake -j4 :

 === building libs/uuid
 === building xenstored
 MLDEP
 MLI      symbol.cmi
 MLI      trie.cmi
 MLOPT    define.cmx
 MLOPT    stdext.cmx

 MLI      uuid.cmi
 MLC      uuid.cmo
 MLOPT    uuid.cmx

 MLA      uuid.cma

On a second gmake run I have:

 === building libs/xs
File "transaction.ml", line 193, characters 2-12:
Error: Unbound value Disk.write

On a third gmake run oxenstored builds.

using OCAML xenstored

[Yuvraj Agarwal]

Hi All,

I would like to give the OCAML version of xenstored a shot, since the
older version (in C) takes a long time to start up a large number of VMs.
I have a new machine (Ubuntu 10.04 64bit) that I plan to give this a try
with. Is there something else that I need to do besides the following: 

1. Build the 2.6.32 pvops kernel as specified in:
http://wiki.xensource.com/xenwiki/XenParavirtOps   
   < DONE >  
2. Download the xen-4.0.0 stable version from
http://www.xen.org/products/xen_source.html 
3. change Config.mk flag CONFIG_OCAML_XENSTORED ?= n to "y"  as" 
   CONFIG_OCAML_XENSTORED ?= y 
4. "make xen", make "tools"  and then the "make xen-install" and "make
install-tools PYTHON_PREFIX_ARG="  

Is there something else needed?  Are there any recent patches to the OCAML
xenstored that I need to apply?

Thank you,
Yuvraj

Just browse through http://xenbits.xen.org/xen-unstable.hd and http://xenbits.xen.org/xen-4.0-testing.hg changelogs.

xen-4.0-testing.hg is currently at 4.0.1-rc1 stage.

FW: using OCAML xenstored

Hi, Just posting this on the list too in case anyone else has experience
with the OCAML version of xenstored….

Hi Boris and Pasi,

I checked out the latest xen-testing from mercurial, and edited the
Config.mk file to have the OCAML version of xenstored built.

I checked and made sure that I have all the patches, and my xm info shows
4.0.1-rc1. After that I built using:

make xen; make tools; make stubdom

make install-xen;
make install-tools PYTHON_PREFIX_ARG=;

make install-stubdom



Unfortunately, it looks like even though the new OCAML version of
xenstored is built, it appears in /usr/bin/xenstored instead of the usual
“/usr/sbin/xenstored” and the default part of the xenstored to use is the
standard one (not the OCAML one)…

Just FYI: This is an Ubuntu 10.04 64 bit system.

root@ BlackBox:/# ll /usr/bin/xenstored   (new OCAML xenstored I just
built..)

-rwxr-xr-x 1 root root 925039 2010-05-25 10:15 /usr/bin/xenstored



root@ BlackBox:/# ll /usr/sbin/xenstored
(<< Standard C xenstored)

-rwxr-xr-x 1 root root 94728 2010-05-01 00:36 /usr/sbin/xenstored



root@ BlackBox:/# which xenstored

/usr/sbin/xenstored

thanks

Re: FW: using OCAML xenstored

Some time ago I sent some patches against xen-ocaml-tools.hg to make it work as 
replacement for the C xenstored in xen-unstable.hg.  One of the patches was to 
fix this install path issue:

http://lists.xensource.com/archives/html/xen-devel/2009-04/msg00697.html

I don't think these patches were applied. (I don't know if there is a reason for 
this.)  It might be worth checking out the whole patch queue if you are 
intending to use it with xen-unstable.hg.

RE: FW: using OCAML xenstored

[Yuvraj Agarwal]

Alex,

Thanks for your tip. Do you think just applying the patch to fix the
install path to the Makefile will fix it or will I need the other 6
patches as well (which seem quite extensive)? I am just wondering if there
was another intended way (by the maintainers) to install the OCAML version
of xenstored side-by-side with the C- version and have the option to use
either one....

Thanks
Yuvraj

Re: FW: using OCAML xenstored

[Alex Zeffertt]

In that patchqueue patches 3/7, 4/7, 5/7, 6/7 are only needed if you are 
compiling the ocaml xenstored to run in a stub domain.  I assume you are 
compiling it for dom0 so you probably don't need it.

Hmm.. so ocaml xenstored is able to run on a stubdom today?
How about xen tools in dom0.. are they able to deal with that?

Well, we tried this a *long* time ago and it worked then - so no guarantees that 
it still works!

However, my understanding is that with the patch queue to xen-ocaml-tools.hg 
applied, and also the small kernel patch queue applied, it should still work. 
Note the kernel patch queue is required to support either the OCAML or C version 
of xenstored in a stubdom.

Regards,

Alex

PS If you are going to use the ocaml xenstored in a stubdom then it might be 
sensible to apply the patch in
http://lists.xensource.com/archives/html/xen-devel/2009-06/msg00505.html as well
