[libvirt] ANNOUNCE: libvirt-glib release 0.0.2
by Daniel P. Berrange 22 Nov '11

22 Nov '11

I am pleased to announce that a new release of the libvirt-glib package, version 0.0.2 is now available from ftp://libvirt.org/libvirt/glib/ The packages are GPG signed with Key fingerprint: DAF3 A6FD B26B 6291 2D0E 8E3F BE86 EBB4 1510 4FDF (4096R) New in this release: - Add API to redefine an existing domain. - Explicitly call virInitialize() to avoid connection races. - Adjust example to latest pygobject-3.0. - Add missing deps on libxml2-devel & libtool. - Add support for writing to streams - Add API for creating transient domains - Change all flags parameters to be guint - Uncomment & fix code for returning object config - Ensure pools & domains hashes are non-NULL to avoid SEGV - Don't de-reference GError instances which are NULL - Update COPYING file to have latest FSF address - Update RPM specfile to include Fedora review feedback libvirt-glib comprises three distinct libraries: - libvirt-glib - Integrate with the GLib event loop and error handling - libvirt-gconfig - Representation of libvirt XML documents as GObjects - libvirt-gobject - Mapping of libvirt APIs into the GObject type system NB: While libvirt aims to be API/ABI stable, for the first few releases, we are *NOT* guaranteeing that libvirt-glib libraries are API/ABI stable. ABI stability will only be guaranteed once the bulk of the APIs have been fleshed out and proved in non-trivial application usage. We anticipate this will be within the next 6 months in order to line up with Fedora 17. Follow up comments about libvirt-glib should be directed to the regular libvir-list(a)redhat.com development list. Thanks to all the people involved in contributing to this release.

[libvirt] [PATCH RESEND v5] Export KVM Host Power Management capabilities
by Srivatsa S. Bhat 22 Nov '11

22 Nov '11

This patch exports KVM Host Power Management capabilities as XML so that higher-level systems management software can make use of these features available in the host. The script "pm-is-supported" (from pm-utils package) is run to discover if Suspend-to-RAM (S3) or Suspend-to-Disk (S4) is supported by the host. If either of them are supported, then a new tag "<power_management>" is introduced in the XML under the <host> tag. Eg: When the host supports both S3 and S4, the XML looks like this: <capabilities> <host> <uuid>dc699581-48a2-11cb-b8a8-9a0265a79bbe</uuid> <cpu> <arch>i686</arch> <model>coreduo</model> <vendor>Intel</vendor> <topology sockets='1' cores='2' threads='1'/> <feature name='xtpr'/> <feature name='tm2'/> <feature name='est'/> <feature name='vmx'/> <feature name='pbe'/> <feature name='tm'/> <feature name='ht'/> <feature name='ss'/> <feature name='acpi'/> <feature name='ds'/> </cpu> <power_management> <<<=== New host power management features <S3/> <S4/> </power_management> <migration_features> <live/> <uri_transports> <uri_transport>tcp</uri_transport> </uri_transports> </migration_features> </host> . . . However in case the query to check for power management features succeeded, but the host does not support any such feature, then the XML will contain an empty <power_management/> tag. In the event that the PM query itself failed, the XML will not contain any "power_management" tag. To use this, new APIs could be implemented in libvirt to exploit power management features such as S3/S4. This was discussed in [1] and [2].

[libvirt] New feature for libvirt network filter
by Amit Tewari 22 Nov '11

22 Nov '11

Hi, I wanted to suggest a new feature in libvirt network filter. Currently libvirt allow only one ip address to be provided in the guest configuration xml file. We should allow multiple ip addresses to be provided statically in the guest xml for an interface, so that packets matching either of these multiple ip addresses should be allowed to be routed out from the guest machine.

[libvirt] problem with nwfilter and ip6tables
by Reinier Schoof 22 Nov '11

22 Nov '11

Hi, I'm investigating using the nwfilter-functionality of libvirt to give my clients the possibility to block ports of their VPSes. The same mechanism allows me to restrict the outgoing traffic a VPS is generating. In the end, I want to restrict MAC, IPv4 and IPv6 traffic, while the client can also restrict traffic to UDP and TCP. All goes well, until I want to restrict the UDP/TCP traffic to certain IPv6 addresses. Where iptables shows the IPv4-restriction I've put up, ip6tables doesn't show anything. In the logs, I only see some ip6tables -D, -X and -F commands failing, which is expected when libvirt tries to delete/flush rules that were never there. I've built my nwfilter containing the following IPv6-rules, which I for instance reference once for all the TCP-ports which should be open.  <filter name='ipv6-allow-statefull' chain='ipv6'> <rule action='accept' direction='in' priority='500'> <all state='ESTABLISHED'/> </rule> <rule action='accept' direction='out' priority='500'> <all state='ESTABLISHED,RELATED'/> </rule> </filter>  <filter name='ipv6-allow-create-state-by-port' chain='ipv6'> <rule action='accept' direction='in' priority='500'> <tcp state='NEW' dstportstart='$PORT'/> </rule> <rule action='accept' direction='in' priority='500'> <udp state='NEW' dstportstart='$PORT'/> </rule> </filter>  <filter name='ipv6-allow-create-state-by-range' chain='ipv6'> <rule action='accept' direction='out' priority='500'> <ipv6 srcipaddr='$RANGE' srcipmask='64'/> </rule> </filter>  <filter name='ipv6-drop-stateless' chain='ipv6'> <rule action='drop' direction='inout' priority='999'> <all/> </rule> </filter> I use a similar approach for my IPv4 firewall, and it works perfectly. When I use these IPv6 rules, all IPv6 traffic is apparently dropped, but it's hard to debug when the result of this config is abscent in ip6tables. I'm using these version of software on debian 6.0 squeeze: virsh # version Compiled against library: libvir 0.9.2 Using library: libvir 0.9.2 Using API: QEMU 0.9.2 Running hypervisor: QEMU 0.15.0 Does anyone have any clues?
