[libvirt] configuring network interface
by Marcela Castro León 08 Feb '11

08 Feb '11

Hello > > I've a lan of virtual machine configured with bridge. I've a private lan of 4 machine, but one of them have 2 lan-card with access to internet. Evertything works almost fine, except that I've configured on each guest the static configuration of the bridge with the ip address, like this: auto lo iface lo inet loopback auto eth6 iface eth6 inet static address 192.168.1.41 network 192.168.1.0 netmask 255.255.255.0 gateway 192.168.1.10 But each time I, for example, define the guest, it start with a ascending number of interface: eth6,eth7, eth8, etc, Now is initializing with eth12. So, it doesn't get the manual configuration I've done on the /etc/network/interfaces. How can avoid this way of work of the number of ethernet interface the guest start? A way i'm trying to solve is configuring the interface trough the guest xml definition, but the operation "define" on virsh accepted without error the xml i've done, but the dumpxml doesn't show them, so, it doesn't work at all. I've followed the instruction that said the manual "Application development guide - a guide to application development with libvirt" on page 71. The whole definition of the VM is attached, but the related to interface is: <interface type='bridge'> <source bridge='br0'/> <target dev='vnet0'/> <protocol> <ip address="192.168.1.41" prefix="24"/> <route gateway="192.168.1.10"/> </protocol> <bridge stp="off" delay="0.01"> <interface type="ethernet" name="eth12"> <protocol> <ip address="192.168.1.41" prefix="24"/> <route gateway="192.168.1.10"/> </protocol> </interface> </bridge> </interface> But after define, the dumpxml only show this part: <interface type='bridge'> <mac address='52:54:00:3c:92:9a'/> <source bridge='br0'/> </interface> I would appreciate any help to solve the question. The problem I've is I lost the access to the guest every time the libvirt change the name of the interface eth1,2,3, etc. Thank you very much. Marcela

[libvirt] [libvirt-php] New project on libvirt.org and information about sending patches
by Michal Novotny 08 Feb '11

08 Feb '11

Hi, based on our yesterday conversation mainly between Radek Hladik from cybersales.cz (who was the project's original maintainer), Justin Clift and me we've decided to move the project from github to libvirt.org to be GIT hosted there. I recommend using this list for the patches to be reviewed there first. I don't know whether we have to establish ACK procedure there or not however posting the patches to this list may be good mainly for brief reviews and option to explicitly NACK the patch if somebody doesn't really like the patch (and have the good reason to don't like it, of course :) ). The procedure for sending patches to libvirt-php (or php-libvirt, as the original name was - I guess both names are acceptable) is recommended to be following: 1. Sign up to libvirt list if you're not on it yet (libvir-list(a)redhat.com) 2. Clone the repository from libvirt.org site using: git clone git://libvirt.org/libvirt-php 3. Set your git username and e-mail and also set the subject prefix in the project's repository using: git config --local format.subjectprefix "libvirt-php" 4. Create the patch in the form of the commits and include also information about usage (example source codes maybe) and testing 5. Format it using `git format-patch -X` where X is the number of patch parts to be posted, for multipart patch (X > 1) please use also numbering (-n) option and include the cover-letter (--cover-letter). 6. Send to libvir-list(a)redhat.com using the `git send-email <files> --to libvir-list(a)redhat.com` command where <files> can be "000*" to send all the patches formatted by git format-patch since git format-patch names the files starting with the 4 digit numbers.

Hmm. At the moment, libvirt only looks for "ccid-card-emulated" in the -device ? list, and hasn't yet tried inspecting -device ccid-card-emulated,? output. In short, libvirt assumes that the presence of ccid-card-emulated implies that both modes are available (libvirt's <smartcard mode='host'/> => backend=nss-emulated; <smartcard mode='host-certificates' => backend=certificates). Is it possible for qemu to have support for one, but not both, of those modes? If that's the case, then supporting "backend=nss-emulated/certificates" in -device ccid-card-emulated,? would be handy for libvirt (for example, it would be just "backend=certificates" if nss-emulated is not available). But if it's an all-or-none approach (all backends are available if ccid-card-emulated is present), then libvirt's current code won't be impacted by changing the string to the simpler "backend=string". -- Eric Blake eblake(a)redhat.com +1-801-349-2682 Libvirt virtualization library http://libvirt.org

[libvirt] draft ~ l10n/i18n
by Zdenek Styblik 07 Feb '11

07 Feb '11

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello, this is a draft of libvirt l10n/i18n translator's how-to. It is nowhere definite and it actually is meant ... It's practically summarized what we've talked about in last couple days. ~~~ DRAFT ~~~ # How-to libvirt l10n/i18n We are glad you've decided to help with localization/internationalization of libvirt. Before you do anything else, stop! Please, pay attention to following lines to save yourself from eventual pitfalls. '.po' files located in this directory are synchronized from Fedora Project[https://translate.fedoraproject.org/projects/p/libvirt/], thus it makes little sense to start translating them. Here are two ways how you can translate and contribute: ## Optimal way 1st step: Create a "Fedora Project" account: https://admin.fedoraproject.org/accounts/ (New Account, etc) 2nd step: Sign in to the libvirt transifex project https://translate.fedoraproject.org/projects/p/libvirt/ It uses the just created Fedora Project account 3rd step: "Request to be a translator" Once you've signed in with step 3, there's a button under the "Translation files" heading that says something like "Request to become a translator". Press that. This is going to take some time. 4th step: Download '.po' file '.po' file can be downloaded at https://translate.fedoraproject.org/projects/p/libvirt/ 5th step: Translate See translator's tools section. 6th step: Upload translated file !!! This point is still a mystery !!! Upload modified file via web interface. ## Alternate way If for some reason you don't want to or can't register at Fedora Project, you still can translate and contribute to libvirt. 1st step: Get '.po' file Download '.po' file from https://translate.fedoraproject.org/projects/p/libvirt/ with language you're going to translate to. Make a backup copy of it 2nd step: Translate See translator's tools section. 3rd step: Make a diff Make a % diff; of the original file and the one you've translated. eg. % diff -urN lang.po.org lang.po > lang.po.patch; Send patch file back to mailing-list and somebody from the team is going to push it at Fedora Project. Why diff? Because it's easier to validate the work you've done, solve eventual conflicts etc. However, this approach has its downsides. First is it brings more workload to libvirt team, second is '.po' file can change in the meantime, because you are not able to "lock it" while you're working at translations. ## Translator's tools * KAider KDE4 ~ seems to be dead * gtranslator ~ http://projects.gnome.org/gtranslator/ * poedit ~ http://www.poedit.net/ In case '.po' file in upstream got changed and you need to sync your current work with upstream, you can try your luck with tool written in Perl > http://www.zeratul.org/git/?p=scripts/perl/po-sync/.git;a=summary ~~~ DRAFT ~~~ Have a nice weekend, Z. - -- Zdenek Styblik Net/Linux admin OS TurnovFree.net email: stybla(a)turnovfree.net jabber: stybla(a)jabber.turnovfree.net -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.10 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAk1DFJ4ACgkQ8MreUbSH7inLvQCeOg3CXKgxkdMz8EKlgQL8hSqK F6gAoI2LbWBPL2WQir0tW2wEjm5NeSlr =/2qM -----END PGP SIGNATURE-----

[libvirt] [PATCH] Support SCSI RAID type & lower log level for unknown types

The Linux kernel headers don't have a value for SCSI type 12, but HAL source code shows this to be a 'raid'. Add workaround for this type.
