[libvirt] [PATCH] Adjust backslash alignment syntax-check
by Martin Kletzander 04 Dec '17

04 Dec '17

We have a check for backslash alignment that checks for two blanks preceding a backslash. However there can be alignment done using a tabulator and in some cases one might be enough. There are none currently, but I found out that was the case before. at some point. so let's check for \t preceding the final backslash as well.

[libvirt] Entering freeze for libvirt-3.10.0
by Daniel Veillard 01 Dec '17

01 Dec '17

As planned yesterday (but a bit late) I tagged Release Candidate 1 in git and pushed the signed tarball and rpms to the usual place: ftp://libvirt.org/libvirt/ Seems to work fine in my limited testing, but please give them a try especially for portability accross arches and platforms ! If things go well (and https://ci.centos.org/view/libvirt/ looks good !) then I will push RC2 on Fraiday and get the final 3.10.0 out on Monday, but please give it some testing and report ! thanks, Daniel -- Daniel Veillard | Red Hat Developers Tools http://developer.redhat.com/ veillard(a)redhat.com | libxml Gnome XML XSLT toolkit http://xmlsoft.org/ http://veillard.com/ | virtualization library http://libvirt.org/

[libvirt] [PATCH] conf: fix migratable XML for graphics if socket is generated based on config
by Pavel Hrdina 30 Nov '17

30 Nov '17

The graphics code is complex and there are a lot of exceptions and backward compatible combinations. One of them is the possibility to configure "spice_auto_unix_socket" in qemu.conf which will convert all spice graphics with listen type "address" without any address specified to listen type "socket" when the guest is started. We don't format this generated socket into migratable XML to make migration work with older libvirt. However, spice has another exception that if autoport='no' and there is no port configured it is converted to listen type "none". Because of this we need to format autoport='yes' to make sure that the listen type will be the same as the offline XML.

[libvirt] [PATCH 0/4] Fix hotplug after daemon restart
by Ján Tomko 30 Nov '17

30 Nov '17

The logic in virQEMUCapsHasPCIMultiBus cannot be reasonably fixed for already running domains, since we dropped the MULTIBUS capability, so only resort to calling it if the domain is using user aliases. That way only hotplug on PPC machines other than pseries with QEMU < 2.0 (possibly older) that have a user alias on pci-root controller stays broken.

[libvirt] [PATCH] qemu: forbid user aliases for implicit pci-root controllers
by Ján Tomko 30 Nov '17

30 Nov '17

For implicit controllers, we do not format user aliases on the command line so we provide a translation between the user alias and the qemu alias. However for pci-root controllers, the logic determining whether to use 'pci' or 'pci.0' depends on: * domain architecture * machine type * QEMU version (for PPC) Since we do not store the QEMU version in status XML and as of commit 5b783379 we no longer have the QEMU_CAPS_PCI_MULTIBUS capability formatted there either, we can only rely on the alias of the controller formatted there. Forbid user aliases for the implicit pci-root controllers so that we retain this information. This allows us to drop the call to virQEMUCapsHasPCIMultiBus, and fixing hotplug after daemon restart, since virQEMUCapsHasPCIMultiBus relies on qemuCaps->arch which is not filled out by reading the status XML either. Partially reverts commit 937f3195 which added the user alias -> qemu alias mapping for implicit PCI controllers. https://bugzilla.redhat.com/show_bug.cgi?id=1518148 --- While we cannot reliably map user aliases to qemu aliases in every corner case, I am not sure where to draw the line. For x86_64, HasPCIMultiBus could be fixed by using def->os.arch instead of qemuCaps->arch. So only PPC is unfixable, but this looked like the option with the least amount of exceptions. src/conf/domain_conf.c | 3 +-- src/conf/domain_conf.h | 2 ++ src/qemu/qemu_command.c | 16 +++++-------- src/qemu/qemu_domain.c | 26 +++++++++++++++++++++- .../qemuxml2argvdata/qemuxml2argv-user-aliases.xml | 4 +--- 5 files changed, 35 insertions(+), 16 deletions(-) diff --git a/src/conf/domain_conf.c b/src/conf/domain_conf.c index 66536653b..d3cd598c8 100644 --- a/src/conf/domain_conf.c +++ b/src/conf/domain_conf.c @@ -6623,7 +6623,6 @@ virDomainDeviceAddressParseXML(xmlNodePtr address, } -#define USER_ALIAS_PREFIX "ua-" #define USER_ALIAS_CHARS \ "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789_-" @@ -6680,7 +6679,7 @@ virDomainDeviceInfoParseXML(virDomainXMLOptionPtr xmlopt ATTRIBUTE_UNUSED, if (!(flags & VIR_DOMAIN_DEF_PARSE_INACTIVE) || (xmlopt->config.features & VIR_DOMAIN_DEF_FEATURE_USER_ALIAS && - STRPREFIX(aliasStr, USER_ALIAS_PREFIX) && + STRPREFIX(aliasStr, VIR_DOMAIN_USER_ALIAS_PREFIX) && strspn(aliasStr, USER_ALIAS_CHARS) == strlen(aliasStr))) VIR_STEAL_PTR(info->alias, aliasStr); } diff --git a/src/conf/domain_conf.h b/src/conf/domain_conf.h index dabbff1c2..de34fb163 100644 --- a/src/conf/domain_conf.h +++ b/src/conf/domain_conf.h @@ -57,6 +57,8 @@ # include "virtypedparam.h" # include "virsavecookie.h" +# define VIR_DOMAIN_USER_ALIAS_PREFIX "ua-" + /* forward declarations of all device types, required by * virDomainDeviceDef */ diff --git a/src/qemu/qemu_command.c b/src/qemu/qemu_command.c index 0eb591253..89e8b5350 100644 --- a/src/qemu/qemu_command.c +++ b/src/qemu/qemu_command.c @@ -321,16 +321,12 @@ qemuBuildDeviceAddressStr(virBufferPtr buf, contIsPHB = virDomainControllerIsPSeriesPHB(cont); contTargetIndex = cont->opts.pciopts.targetIndex; - /* When domain has builtin pci-root controller we don't put it - * onto cmd line.
