[libvirt] virt-manager
by Michael Zeller 06 Aug '09

06 Aug '09

okay so using virt-manager it only lists my root partition as storage, or atleast thats what it appears So it says I can only make a vm the size of 9G when my home partition has 800+G is there a way to change that?

[libvirt] libvirt-0.3.3-14.el5 (redhat rpm) vs libvirt-0.6.5 (source)
by Jim Bergensen 06 Aug '09

06 Aug '09

Hello everyone, I am looking to write a simple php interface to create, stop, start, restart, configure, backup, transfer VM's across a network of servers. Storage is done locally on the particular node (lvm), but I am considering to do this through iscsi in the future. Xen, KVM, IP management, firewalling is an important requirement. The redhat backport version looks outdated, but I know the version number isn't the best way to compare features. My questions are: - Featurewise, is the difference between the redhat version and the libvirt.org source version small or as big as it looks (branch versions?) - Considering the above functions I am going to need, will the redhat version suffice? Any help would be truely appreciated, Thank you, Jim

[libvirt] running with UID != 0: internal error about bridged network

[libvirt] [PATCH 0/7] QEMU network/bridge backed NIC hotplug
by Mark McLoughlin 05 Aug '09

05 Aug '09

Hey, So, here are the patches needed to complete the QEMU NIC hotplug work by supporting network and bridge backed interfaces. We support this by passing a tap file descriptor to qemu over the monitor socket using SCM_RIGHTS. The monitor commands required for this (getfd and closefd) are queued up in Anthony's queue and should be in qemu-0.11-rc1 which is due to be released very soon: http://repo.or.cz/w/qemu/aliguori-queue.git?a=commitdiff;h=4edd6c2645 http://repo.or.cz/w/qemu/aliguori-queue.git?a=commitdiff;h=f4069061e3 Note: I just remembered I'm not handling missing support for these commands very well. I'll make it handle an 'unknown command' reply gracefully by failing the attach tommorrow. Cheers, Mark.

[libvirt] [PATCH] address incompatible change of qemu-img
by Ryota Ozaki 05 Aug '09

05 Aug '09

Hi, Latest qemu-img (maybe from 0.11.0-rc0 or later?) changes default unit of size as bytes, it was kilo-bytes so far. (see http://www.mail-archive.com/kvm@vger.kernel.org/msg19183.html) This patch addresses this incompatibility by adding postfix 'K'. This fix is able to keep backward compatibility for old qemu as well, and also even if qemu-img falls back old style or any, this explicit specifying should work well. Thanks, ozaki-r >From 7d3dd9e592deab5a1d793532cf230d8367372280 Mon Sep 17 00:00:00 2001 From: Ryota Ozaki <ozaki.ryota(a)gmail.com> Date: Tue, 4 Aug 2009 11:11:31 +0900 Subject: [PATCH] address incompatible change of qemu-img --- src/storage_backend.c | 2 +- 1 files changed, 1 insertions(+), 1 deletions(-) diff --git a/src/storage_backend.c b/src/storage_backend.c index 07a2e48..8824218 100644 --- a/src/storage_backend.c +++ b/src/storage_backend.c @@ -446,7 +446,7 @@ virStorageBackendCreateQemuImg(virConnectPtr conn, /* Size in KB */ - snprintf(size, sizeof(size), "%llu", vol->capacity/1024); + snprintf(size, sizeof(size), "%lluK", vol->capacity/1024); if (virRun(conn, imgargv, NULL) < 0) { VIR_FREE(imgargv[0]); -- 1.6.0.6

[libvirt] [PATCH] Support the usage of socat instead of netcat
by Jonas Eriksson 05 Aug '09

05 Aug '09

Some netcat implementations does not support unix domain sockets (-U). Distros that ship these implementations often also ships socat, that do support this. This is a reworked patch based on the openSUSE libvirt package. The original patch may be found in this source rpm: http://download.opensuse.org/source/distribution/11.1/repo/oss/suse/src/lib… * configure.in: Check for --with-socat and set USE_SOCAT in config.h * src/remote_internal.c: Honour USE_SOCAT by selecting between netcat/nc and socat at compile time. --- configure.in | 7 +++++++ src/remote_internal.c | 13 +++++++++++++ 2 files changed, 20 insertions(+), 0 deletions(-) diff --git a/configure.in b/configure.in index b905b23..732ef68 100644 --- a/configure.in +++ b/configure.in @@ -153,6 +153,13 @@ if test -n "$MODPROBE"; then [Location or name of the modprobe program]) fi +dnl Check if socat should be used instead of netcat +AC_ARG_WITH([socat], +[ --with-socat use socat instead of netcat (off)]) +if test "$with_socat" = "yes" ; then + AC_DEFINE_UNQUOTED([USE_SOCAT], 1, [whether socat should be used instead of netcat]) +fi + dnl Specific dir for HTML output ?
