[libvirt] libxl driver doesn't build with xen 4.2
by Cole Robinson 29 Oct '12

29 Oct '12

Hi Jim, The libvirt libxl driver doesn't build with xen 4.2. There was a small thread about it on fedora's virt list: http://lists.fedoraproject.org/pipermail/virt/2012-October/003446.html I saw that you had a few xen 4.2 patches land recently, and I'm just curious if you were aware of the libxl issues/possibly had any patches brewing. Currently in fedora we've disabled building the libxl driver so the xen guys can pull in their latest bits. Thanks, Cole

You can try a different network config either using the virt-manager GUI tool or by editing the network XML, which is documented here: http://libvirt.org/formatnetwork.html CCed libvirt mailing list.

[libvirt] [PATCH] daemon: Fix LIBVIRT_DEBUG=1 default output
by Cole Robinson 29 Oct '12

29 Oct '12

This commit changes the behavior of LIBVIRT_DEBUG=1 libvirtd: $ git show 7022b09111d4322d21396a70d58320a9ad773962 commit 7022b09111d4322d21396a70d58320a9ad773962 Author: Daniel P. Berrange <berrange(a)redhat.com> Date: Thu Sep 27 13:13:09 2012 +0100 Automatically enable systemd journal logging Probe to see if the systemd journal is accessible, and if so enable logging to the journal by default, rather than stderr (current default under systemd). Previously 'LIBVIRT_DEBUG=1 /usr/sbin/libvirtd' would show all debug output to stderr, now it send debug output to the journal. Only use the journal by default if running in daemon mode, or if stdin is _not_ a tty. This should make libvirtd launched from systemd use the journal, but preserve the old behavior in most situations. --- daemon/libvirtd.c | 9 ++++++--- src/util/logging.c | 2 ++ 2 files changed, 8 insertions(+), 3 deletions(-) diff --git a/daemon/libvirtd.c b/daemon/libvirtd.c index d2e0a04..279a9d1 100644 --- a/daemon/libvirtd.c +++ b/daemon/libvirtd.c @@ -636,10 +636,13 @@ daemonSetupLogging(struct daemonConfig *config, virLogParseOutputs(config->log_outputs); /* - * If no defined outputs, then first try to direct it - * to the systemd journal (if it exists).... + * If no defined outputs, and either running + * as daemon or not on a tty, then first try + * to direct it to the systemd journal + * (if it exists).... */ - if (virLogGetNbOutputs() == 0) { + if (virLogGetNbOutputs() == 0 && + (godaemon || isatty(STDIN_FILENO) != 1)) { char *tmp; if (access("/run/systemd/journal/socket", W_OK) >= 0) { if (virAsprintf(&tmp, "%d:journald", virLogGetDefaultPriority()) < 0) diff --git a/src/util/logging.c b/src/util/logging.c index 9a8bba1..dd43842 100644 --- a/src/util/logging.c +++ b/src/util/logging.c @@ -1247,6 +1247,8 @@ virLogParseOutputs(const char *outputs) if (cur == NULL) return -1; + VIR_DEBUG("outputs=%s", outputs); + virSkipSpaces(&cur); while (*cur != 0) { prio= virParseNumber(&cur); -- 1.7.11.7

[libvirt] [PATCH] [DRAFT] handle qemu event GUEST_PANICKED
by Hu Tao 29 Oct '12

29 Oct '12

This is for early review, comments are welcome! qemu is adding a method to detect guest panic, and a new event GUEST_PANICKED[1]. This patch adds support for GUEST_PANICKED. But I have two questions: - to react to GUEST_PANICKED, can xml element <on_crash> be used as the action to take, or do I have to invent another xml element to configure the action? - Currently libvirt relies on watchdog to detect guest panic, but this way is not that reliable(there has to be a watchdog device, the watchdog itself has to be working when panic occurs), so it seems to be appropriate to remove this method from libvirt as there is a better one. But, will the removal cause any problems, such as backward compatibility, user confusion, etc.?

[libvirt] [PATCH v3] xml: print uuids in the warning
by Ján Tomko 29 Oct '12

29 Oct '12

In the XML warning, we print a virsh command line that can be used to edit that XML. This patch prints UUIDs if the entity name contains special characters (like shell metacharacters, or "--" that would break parsing of the XML comment). If the entity doesn't have a UUID, just print the virsh command that can be used to edit it. --- As opposed to previous versions, this doesn't use virBuffer and it doesn't do any shell escaping at all. The name parameter can be null now. commit 9b704ab8235af010b1fda4886201aab02098b969 xml: omit domain name from comment if it contains double hyphen only checked the 'name' parameter of virXMLEmitWarning. virXMLSaveFile invocation when creating a snapshot put the domain name in 'cmd', which means that snapshot XMLs of a domain with "--" in the name still can't be parsed by libvirt. --- src/conf/domain_conf.c | 6 +++++- src/conf/network_conf.c | 6 +++++- src/conf/nwfilter_conf.c | 12 ++++++++++-- src/conf/storage_conf.c | 6 +++++- src/libvirt_private.syms | 1 + src/parallels/parallels_storage.c | 3 +-- src/qemu/qemu_domain.c | 9 +-------- src/util/xml.c | 18 +++++++++++++----- src/util/xml.h | 1 + 9 files changed, 42 insertions(+), 20 deletions(-) diff --git a/src/conf/domain_conf.c b/src/conf/domain_conf.c index 90ec9aa..7bf0282 100644 --- a/src/conf/domain_conf.c +++ b/src/conf/domain_conf.c @@ -14288,6 +14288,7 @@ int virDomainSaveXML(const char *configDir, virDomainDefPtr def, const char *xml) { + char uuidstr[VIR_UUID_STRING_BUFLEN];

[libvirt] How you can help with maintenance releases
by Cole Robinson 28 Oct '12

28 Oct '12

Hey all, As you're likely aware, I've been cutting maintenance releases of certain libvirt versions for the past six months: http://wiki.libvirt.org/page/Maintenance_Releases Since I'm not hugely involved with development these days, and things move pretty quick in libvirt land, I'd like to appeal to you fine gentleman for a bit of assistance here. None of this is mandatory, but hopefully it's low enough effort that I get a few bites :) Here's the gist: Next time you post a bug fix for an issue you can imagine someone actually hitting and filing a bug report about, consider doing one of the following: - Pushing the patch to the relevant maint branches - CCing me on the posting, with a note that this might be a maint candidate Of course, doing this for patches that someone else posts is completely fine with me too :) Take a look at the current branched versions and their original release dates: libvirt 0.9.6: Sep 22 2011 libvirt 0.9.11: Apr 3 2012 libvirt 0.10.2: September 24 2012 So if you find a bug in code that you know hasn't been touched for a year, it might be a candidate for all 3 branches! Jiri recently noticed this and cherry-picked a patch, (which was very much appreciated!): http://libvirt.org/git/?p=libvirt.git;a=commit;h=bebe5122b9af50f0b25f47f30e… http://libvirt.org/git/?p=libvirt.git;a=commit;h=d325704a3fdf947fa862bf62ec… http://libvirt.org/git/?p=libvirt.git;a=commit;h=77cecd2bc306416d985230bb29… As an example of how to push a patch to a maintenance branch, say you want to backport master commit ab12cd34: git checkout --track remotes/origin/v0.10.2-maint git checkout v0.10.2-maint git cherry-pick -x ab12cd34 git push v0.10.2-maint If the cherry-pick doesn't apply cleanly, feel free to just CC me and I'll straighten it out. That's it! Let me know if you have any questions. Thanks, Cole
