[libvirt] Question SSH support and libirt on Windows
by Atsushi SAKAI 08 Aug '08

Hi, Rich I have a question about SSH support of libvirt on Windows. Is there any reason for not supporting SSH. It is just because it lacks manpower? Thanks Atsushi SAKAI

[libvirt] [PATCH] fix xmlint in separate build dir

Hi, attached patch lets the domainschema check work when building in $build instead of $src. Otherwise it won't find the xml files to validate. -- Guido

[libvirt] ISCSI Live Migration with LUN backed VMs
by Tim Hughes 07 Aug '08

07 Aug '08

I am using iscsi backed VMs which use a separate LUN for each VM. This is all good until I try to live migrate because the LUN is not logged into on the new machine. Does anyone have a way of handling logging into and out of iscsi luns during the migration ? Tim Hughes mailto:thughes@thegoldfish.org

[libvirt] default networking issues
by Bryan Kearney 07 Aug '08

07 Aug '08

Need some help about where to look next. I am running a Fedora 9 machine, up to date on the releaed rpms. SELinux is permissive, iptables is stopped. I have followed the instructions for NAT forwarding [1]. When I launch a guest in virt manager it uses the default network, and is assigned an IP address in the 192.168.122 space. It can do dns resolution, but can not wget a known website (www.cnn.com) From my host machine, I can ssh into the guest. Where is the next place I should look. Is the fact that I am running in a corporate network causing me issues? Thanks! -- bk [1] http://wiki.libvirt.org/page/Networking#NAT_forwarding_.28aka_.22virtual_ne…

[libvirt] [PATCH] The logic in veth.c that searches for free interface names takes into account
by Dan Smith 07 Aug '08

07 Aug '08

only current devices, but not device names already planned for the other half of a container's device pair. Thus, the search can result in attempting to create a pair of devices such as veth1 and veth1, which obviously does not work. This patch augments the logic to be a little smarter in this regard, and should fix one case where attempting to start a container results in an error message of "unable to create device pair". diff -r 8c5e6387e449 -r 8545f7ac1f0f src/veth.c --- a/src/veth.c Tue Aug 05 16:45:07 2008 +0000 +++ b/src/veth.c Wed Aug 06 08:14:16 2008 -0700 @@ -92,17 +92,18 @@ DEBUG("veth1: %s veth2: %s", veth1, veth2); - if (1 > strlen(veth1)) { + while ((1 > strlen(veth1)) || STREQ(veth1, veth2)) { vethDev = getFreeVethName(veth1, veth1MaxLen, 0); ++vethDev; DEBUG("assigned veth1: %s", veth1); } - if (1 > strlen(veth2)) { + while ((1 > strlen(veth2)) || STREQ(veth1, veth2)) { vethDev = getFreeVethName(veth2, veth2MaxLen, vethDev); DEBUG("assigned veth2: %s", veth2); } + DEBUG("veth1: %s veth2: %s", veth1, veth2); rc = virRun(NULL, (char**)argv, &cmdResult); if (0 == rc) {

[libvirt] update from gnulib
by Jim Meyering 07 Aug '08

07 Aug '08

I've just checked in a big batch of changes from gnulib. Each of those changes has been reviewed by at least two people (see bug-gnulib(a)gnu.org) and most of them address problems also reported on that list, or e.g., on bug-coreutils, bug-m4, etc. However, I suspect some of them have not yet been exercised on RHEL4/5 systems, so test builds there may be interesting. >From e6440820773161436812ccad7eba6d555a8186dd Mon Sep 17 00:00:00 2001 From: Jim Meyering <meyering(a)redhat.com> Date: Thu, 7 Aug 2008 10:28:22 +0200 Subject: [PATCH] update from gnulib * build-aux/mktempd (rand_bytes, mktempd): * build-aux/useless-if-before-free (FILE): * build-aux/vc-list-files: * gnulib/lib/.cvsignore: * gnulib/lib/Makefile.am: * gnulib/lib/poll.c (poll): * gnulib/lib/stdbool.in.h (_GL_STDBOOL_H, true): * gnulib/lib/stdio-impl.h (fp_, fp_ub): * gnulib/lib/stdio.in.h (vasprintf, obstack_printf) (obstack_vprintf): * gnulib/lib/vasnprintf.c (_GNU_SOURCE, sprintf, IF_LINT, exp) (remainder, scale10_round_decimal_long_double) (scale10_round_decimal_double, pad_ourselves): * gnulib/m4/gnulib-cache.m4: * gnulib/m4/gnulib-common.m4 (gl_MODULE_INDICATOR): * gnulib/m4/gnulib-tool.m4 (gl_LOCAL_DIR, gl_M4_BASE, gl_PO_BASE) (gl_DOC_BASE, gl_TESTS_BASE, gl_WITH_TESTS, gl_LIB, gl_LGPL) (gl_MAKEFILE_NAME, gl_MACRO_PREFIX, gl_PO_DOMAIN, gl_VC_FILES): * gnulib/m4/lock.m4 (gl_LOCK_EARLY_BODY, gl_PREREQ_LOCK) (gl_DISABLE_THREADS): * gnulib/m4/onceonly.m4: * gnulib/m4/posix-shell.m4 (gl_POSIX_SHELL): * gnulib/m4/stdio_h.m4 (gl_STDIO_H_DEFAULTS): * gnulib/tests/test-getaddrinfo.c (ENABLE_DEBUGGING, dbgprintf) (simple): * gnulib/tests/test-stdint.c (UINTMAX_MAX, or): * gnulib/tests/test-vc-list-files-cvs.sh (compare): * gnulib/tests/test-vc-list-files-git.sh (compare): --- build-aux/mktempd | 6 +++- build-aux/useless-if-before-free | 32 +++++++++++++++--------- build-aux/vc-list-files | 5 ++- gnulib/lib/.cvsignore | 12 ++++---- gnulib/lib/Makefile.am | 15 +++++++++++- gnulib/lib/poll.c | 34 ++++++++++++++++++------- gnulib/lib/stdbool.in.h | 6 ++-- gnulib/lib/stdio-impl.h | 4 +- gnulib/lib/stdio.in.h | 20 +++++++++++++++ gnulib/lib/vasnprintf.c | 25 +++++++++++++++---- gnulib/m4/gnulib-cache.m4 | 21 ++++++++++++++- gnulib/m4/gnulib-common.m4 | 9 ++++++- gnulib/m4/gnulib-tool.m4 | 28 ++++++++++++++++++++- gnulib/m4/lock.m4 | 37 +++++++++++++++++++++------- gnulib/m4/onceonly.m4 | 15 +++++++---- gnulib/m4/posix-shell.m4 | 7 +++-- gnulib/m4/stdio_h.m4 | 6 ++++- gnulib/tests/test-getaddrinfo.c | 41 +++++++++++++++++++------------ gnulib/tests/test-stdint.c | 6 ++++- gnulib/tests/test-vc-list-files-cvs.sh | 3 +- gnulib/tests/test-vc-list-files-git.sh | 3 +- 21 files changed, 249 insertions(+), 86 deletions(-)

[libvirt] [PATCH] Install default storage pool
by Cole Robinson 07 Aug '08

07 Aug '08

The attached patch adds a default pool definition to install with libvirt. The pool is a directory pool, hardcoded to use /var/lib/libvirt/images, though this is replaced with %{_localstatedir}/lib/libvirt/images if installing via rpm. Since /var/lib/libvirt/images may not exist if installing from tar.gz, the pool is set not to autostart by default via that method. This patch isn't ready to apply though, since there is one issue I don't know how to solve. We don't want every rpm upgrade to install the default pool, since we don't want the default to continually resurrect itself if a user explicitly deletes it. The default network handles this by checking if libvirtd has been installed. Since libvirtd and virtual network support were introduced around the same time, this makes sense. However for storage, I can't think of any simple check we can make. If we used the same as the default network, all f8 or f9 upgrades wouldn't install the default pool. I can't really think of anything to check, besides maybe doing some sort of time comparison on when /usr/share/libvirt/storage/default.xml was accessed. This code is just hardcoded to always add it. Any ideas? Thanks, Cole

[libvirt] How does virt-manager send shutdown?
by Bryan Kearney 07 Aug '08

07 Aug '08

How does virt-manager send shutdown to guests? Does it depend on if you are running kvm or xen? I have been building images with acpid enabled and acpi=force on the command line. After upgrading to f9 and running kvm my images no longer respond to shutdown. Is there a tweak which I have missed? - bk
