[libvirt] Python binding to virConnectListInterfaces
by Shahar Klein 16 Sep '09

16 Sep '09

Hi I'm trying to implement virConnectListInterfaces for the ESX driver (actually the esx_interface driver) but the python generator does not write the code for this function in generator.py this function is in a special table called: skip_impl and there is a comment saying: # Class methods which are written by hand in libvir.c but the Python-level # code is still automatically generated (so they are not in skip_function()) I'm not sure what does it mean should I implement in libvir.c? and I'm done? thanks ahead Shahar

[libvirt] [PATCH] doc: don't emit trailing blanks into generated and VC'd NEWS file
by Jim Meyering 15 Sep '09

Daniel Veillard reported that the generated and VC'd NEWS file was causing trouble because the latest version contains trailing spaces, which conflicts with our server-side hook to prevent that. Here's the fix to avoid emitting those trailing spaces: >From 8110d304f49a217021371321ade0026ccd2627e1 Mon Sep 17 00:00:00 2001 From: Jim Meyering <meyering(a)redhat.com> Date: Tue, 15 Sep 2009 15:01:26 +0200 Subject: [PATCH] doc: don't emit trailing blanks into generated and VC'd NEWS file * docs/Makefile.am ($(top_builddir)/NEWS): Filter out trailing white space. --- docs/Makefile.am | 1 + 1 files changed, 1 insertions(+), 0 deletions(-) diff --git a/docs/Makefile.am b/docs/Makefile.am index 9ac2f6d..1125931 100644 --- a/docs/Makefile.am +++ b/docs/Makefile.am @@ -131,6 +131,7 @@ $(top_builddir)/NEWS: $(top_srcdir)/docs/news.xsl $(top_srcdir)/docs/news.html.i $(XSLTPROC) --nonet $(top_srcdir)/docs/news.xsl \ $(top_srcdir)/docs/news.html.in \ | perl -0777 -pe 's/\n\n+$$/\n/' \ + | perl -pe 's/[ \t]+$//' \ > $@-t && mv $@-t $@ ; fi ); clean-local: -- 1.6.5.rc1.171.g3f463

[libvirt] Trouble booting Xen VM with NFS root file system
by Matthias Schmidt 15 Sep '09

15 Sep '09

Hi, I'm currently trying to boot a Xen VM with the root file system on NFS via libvirt. Previously we used a small python script and "xm create" to boot a number of VMs (which worked fine). Now I'm trying to integrate that functionality in a python project which uses libvirt, but sadly booting the VMs fail. The small script constructs a Xen command line which looks like the following: create =("/usr/sbin/xm create /foo.cfg \ kernel=%s ramdisk=%s memory=64\ root=/dev/nfs nfs_server=%s nfs_root=%s name=%s vif='mac=%s'\ dhcp='dhcp' vcpus=1 extra='init=/stateless.sh xencons=tty1'\ ")%(vm_kernel, vm_ramdisk, vm_nfs_server, vm_nfs_root, hostname, vif) kernel and ramdisk are the path to the installed version, vm_nfs_server is the IP address of the NFS server and vm_nfs_root the path to the operating system installation (which is a Debian Linux). Firing up the script brings up all VMs with a read-only NFS root file system. Now I tried to do this with libvirt, but all attempts failed with the following error popping up after the VM boots (after a certain time(out)): Gave up waiting for root device. Common problems: - Boot args (cat /proc/cmdline) - Check rootdelay= (did the system wait long enough?) - Check root= (did the system wait for the right device?) - Missing modules (cat /proc/modules; ls /dev) ALERT! /dev/nfs does not exist. Dropping to a shell! BusyBox v1.10.2 (Debian 1:1.10.2-2) built-in shell (ash) Enter 'help' for a list of built-in commands. /bin/sh: can't access tty; job control turned off (initramfs) cat /proc/cmdline root=/dev/nfs nfs_server=10.0.0.150 nfs_root=/opt/xge/util/ph vif="mac=1A:00:00:00:00:64" dhcp=dhcp extra="init=./stateless.sh xencons=tty" The cmdline looks the same as in the script, but booting won't work. I can provide the libvirt XML used to boot the VM and further information if that is necessary. Cheers Matthias PS: I'm using Xen 3.2.1, Kernel 2.6.26 and libvirt 0.6.3 from Debian here.

[libvirt] RFE storage cloning across connections.
by "Jóhann B. Guðmundsson" 15 Sep '09

15 Sep '09

Virt-manager now supports migration and VM cloning however cloning only works within a connection though so you can't clone to another machine. It certainly would be a nice addition if supports storage cloning across connections. Best regards. Jóhann B.

Okay, I finally got the patches cleaned up. I just posted this 12 patches series to the mailing list. Apply them all to an up to date git clone and apply the attached, updated ESX interface driver stub patch in the end. Patch 6 of 12 adds the binding for HostCpuIdInfo and contains the functions to handle ArrayOf* types.

[libvirt] [PATCH 0/4] Changes to API/ABI for secrets handling
by Daniel P. Berrange 14 Sep '09

14 Sep '09

This series makes two changes to the public API and wire protocol ABI for the secrets handling support recently committed. As such this is a must fix before we do the release, since we can't break compatability once released. The first patch changes all the code to store UUIDs in raw format instead of printable format. This is important because it ensures that e3a9758f-b0c6-7a3a-ebb9-71a69c930289 is treated exactly the same as e3a9758fb0c67a3aebb971a69c930289, which is not the case with the currently committed code. It also makes the secrets and storage encryption XML parsers use the internal UUID handling APIs The second patch adds a new unique property to virSecretPtr. The "owner ID" is intended to be unique on a host wrt all secrets with matching usage type. This entails adding 2 APIs to querying the usage type, and another API to lookup a secret based on its usage. In testing the current code I frequently found myself getting into the situation where there were many secrets for the same volume which was not at all good. So if defining a secret to be used with a storage volume this ensures that you only ever have one secret associated with each storage volume path. The third patch ensures that when you query the XML for a qcow encrypted voluem, it will include the UUID of the secret. Previously if you created a volume, and then restarted libvirtd, the secret UUID would be lost. This patch is why we need the new API from the second patch virLookupSecretByUsage - without that it would be impossible to lookup the secret efficiently. THe final patch is a minor tweak to the RNG
