// Unmount everything. g.umount_all ();

hello everyone! first i use libguestfs API to upload a file into my linux VM , and then i want to execute some command(for example : tar xzvf XXX、 chkconfig --add XXX) to config my application by java libguestfs API，what should i do? could you show me an example in java? Thanks!

i try it in my environment，it allways throws the exception : com.redhat.et.libguestfs.LibGuestFSException: sh: /bin/sh: Exec format error then i try the following programs, "Exec format error" still happens: String cmd1 = "chkconfig --add tomcat"; g.sh(cmd1); String cmd2 = "/sbin/chkconfig --add tomcat"; g.sh(cmd2); String[] cmd = new String[] {"/sbin/chkconfig", "--list"}; g.command(cmd); but i can execute the command in system, could show me the reason, Thanks!

However to run the command it may be better to run the command using a "firstboot" script. See: http://libguestfs.org/guestfs.3.html#running-commands http://libguestfs.org/virt-sysprep.1.html#firstboot- (Note that the ability to use firstboot scripts was only added very recently to virt-sysprep).

Well as I said, the --firstboot option was only added very recently. You could try to copy what this option does by looking at the source code: https://github.com/libguestfs/libguestfs/blob/c638e1f03d2700560fe32c08892... But I don't have the time to translate all that into Java for you. You'll have to ask a local expert.

i'm so sorry that i still don't know what to do, i execute the command but [virt-sysprep: unknown option `--firstboot' ] execption happens, could you show me the detail? Thanks!

and i have another question: now , i use ssh2 api to execute the remote virt-XXX(virt-win-reg virt-sysprep ......) command, is there java api like guestfs?

4、execute the command in this format virt-sysprep -a XXXX.img \ --firstboot XXX.sh 5、startup my VM

hi Jones! i configured this virsion with the following command : ./configure --disable-ocaml --disable-perl --disable-ruby --disable-haskell --disable-php --with-java-home=no

but make command leads to : make[5]: Entering directory `/home/zhoutao/upload/libguestfs-1.19.35/generator' make[5]: `stamp-generator' is up to date. make[5]: Leaving directory `/home/zhoutao/upload/libguestfs-1.19.35/generator' GISCAN Guestfs-1.0.gir /usr/local/lib/libguestfs.so.0: undefined reference to `guestfs___read_db_dump' collect2: error: ld returned 1 exit status linking of temporary binary failed: Command '['bash', '../libtool-kill-dependency_libs.sh', '../libtool', '--mode=link', '--tag=CC', '--silent', 'gcc', '-o', '/home/zhoutao/upload/libguestfs-1.19.35/gobject/tmp-introspectoNR7uD/Guestfs-1.0', '-export-dynamic', '/home/zhoutao/upload/libguestfs-1.19.35/gobject/tmp-introspectoNR7uD/Guestfs-1.0.o', '-L.', 'libguestfs-gobject-1.0.la', '-pthread', '-Wl,--export-dynamic', '-lgio-2.0', '-lgobject-2.0', '-lgthread-2.0', '-lgmodule-2.0', '-lrt', '-lglib-2.0']' returned non-zero exit status 1 make[4]: *** [Guestfs-1.0.gir] Error 1 make[4]: Leaving directory `/home/zhoutao/upload/libguestfs-1.19.35/gobject' make[3]: *** [all-recursive] Error 1 make[3]: Leaving directory `/home/zhoutao/upload/libguestfs-1.19.35/gobject' make[2]: *** [all] Error 2 make[2]: Leaving directory `/home/zhoutao/upload/libguestfs-1.19.35/gobject' make[1]: *** [all-recursive] Error 1 make[1]: Leaving directory `/home/zhoutao/upload/libguestfs-1.19.35' make: *** [all] Error 2 is there something need to be installed? could you help me oncemore.

does redhat supply an free yum repo for installing the latest version libguestfs? now , i use 163 yum repo, but it's latest version is 1.18.6

i yum install V1.18.6 on Fedora 17, and then compiled libguestfs 1.19.35 from source on the same machine, although the installing is error, the local guestfs version has been changed to 1.19.35，and i can execute [--firstboot] command，so your guess is right。 next monday, i will test as you say, thank you for your patient help

yes, i followed the steps of README, run "./configure" and "make" without any parameters, i think all the dependencies have been installed because of "./configure" could be run successfully. and just now, i rerun "./configure" & "make" for checking, but the error still happened.

It is possible to run 'make install', but we normally do not recommend you do that. To avoid conflicts between other packages, you should build a libguestfs package for your Linux distro, which is not so easy.

[The context for libvirt users is how to let people do 'make install' without having conflicts with installed copies of packages.] On Wed, Sep 05, 2012 at 07:39:37AM -0400, Whit Blauvelt wrote: > On Wed, Sep 05, 2012 at 08:07:09AM +0100, Richard W.M.

I'm not sure how special libvirt & qemu are. You could try installing to a local prefix (I sometimes use "./configure --prefix=$HOME/gnu"). Then you have to sort out the environment variables that need setting. I don't think libvirt or libguestfs or qemu document what environment variables should be set to run an internally consistent local copy of the entire libvirt/KVM stack from your home directory. libguestfs has the "./run" script which can be modified. Anyone got any thoughts? I think it is a genuine concern.

hi jones! is there any way to modify running VM's image using libguestfs? i want to install some softwares onto the running vm.

Thanks! ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ 周涛

However you might want to look at libguestfs-live, which involves installing a daemon in the VM that libguestfs talks to: https://rwmj.wordpress.com/2011/07/06/libguestfs-live/ https://rwmj.wordpress.com/tag/libguestfs-live/ (Currently this only works for Linux VMs)

Also, if the VM is switched off, you can install a firstboot script (as previously discussed). This script runs when the guest boots, and can install software etc.

Thanks!
