03 Mar '09

HI All I have KVM virtual machine running under bridging.I don't want to use bridging/Nating.I want to use routing via IPTABLES to route traffic toward the virtual machine is that possible.These thing benifit me in flitering .And i have live ip on virtual machine.Please let me how i can achive this. _________________________________________________________________ Windows Live™ Groups: Create an online spot for your favorite groups to meet. http://windowslive.com/online/groups?ocid=TXT_TAGLM_WL_groups_032009

[libvirt] [PATCH] virsh: adjust remaining format strings to avoid emitting trailing space

[libvirt] PATCH: Remove qemudLog() macro, use logging.h instead
by Daniel P. Berrange 03 Mar '09

03 Mar '09

The qemudLog() macro just spews its messages to stderr. This patch changes it to use the proper logging.h APIs, so the output channel is configurable in the expected way.

[libvirt] tls_allowed_ip_list?
by Chris Lalancette 03 Mar '09

03 Mar '09

All, While doing testing on TLS, I came across the mention of "tls_allowed_ip_list" in the website documentation, here: http://libvirt.org/remote.html#Remote_libvirtd_configuration However, I don't see any implementation of the tls_allowed_ip_list in libvirt itself; a grep through the sources show that we are implementing "tls_allowed_dn_list", but not "tls_allowed_ip_list". Am I missing something in the sources? Should we update the libvirt.org documentation and remove that (seemingly non-existent) parameter? Or should I go in and implement the "tls_allowed_ip_list"? -- Chris Lalancette

[libvirt] [PATCH]: Fix qemu+tls negotiation
by Chris Lalancette 03 Mar '09

03 Mar '09

All, While doing testing on the migration stuff, I noticed that a connection string using tls (in my case, qemu+tls://host/system) was hanging up trying to connect. I traced this down to a bug in the newer qemud negotiation implementation. What is happening is that we are forgetting to clear client->handshake to 0 after successfully doing a remoteAccessCheck(); this means we were never putting the '\1' byte on the transmit queue to be sent to the client, so the client was essentially waiting forever for the server to respond. Fix this by clearing the handshake once we've successfully done the handshake. Signed-off-by: Chris Lalancette <clalance(a)redhat.com>

[libvirt] [PATCH 1..2] make a test more robust, and add two more
by Jim Meyering 03 Mar '09

03 Mar '09

Here's a rebased patch from a month or two ago. It's only fixing and adding tests, so I'll commit it momentarily. Dan Berrange noticed that daemon-conf could interfere with existing domains, so the latter patch below makes it use the new log-setting and unix_sock_dir-setting config options as well as the option to select a per-test PID file. >From efee209a2adf6f2478de26fe25c73bd4c38316ea Mon Sep 17 00:00:00 2001 From: Jim Meyering <meyering(a)redhat.com> Date: Thu, 8 Jan 2009 20:18:17 +0100 Subject: [PATCH 1/2] add two tests * tests/libvirtd-pool: New file.

[libvirt] [PATCH] Don't log qemu monitor output from blockStats
by Cole Robinson 03 Mar '09

03 Mar '09

The attached patch changes the qemu driver blockStats command to not log qemu monitor output. virt-manager offers an option to continually poll VM disk stats, and if the app is left running for a while with many VMs, this can make the logs huge, for little benefit (a user reported 100 MB with virt-manager left running overnight). The output from the command is still printed with a DEBUG call, so the info isn't completely lost. Thanks, Cole
