While running make check, I noticed that it was actually using the virsh binary from my system, in /usr/bin/virsh, and not the one that was just compiled. This is actually caused by a bug in Makefile.am, where we didn't update the PATH to include tools. While here, I also updated all of the scripts to properly define the srcdir, abs_top_srcdir, and abs_top_builddir environment variables. This is required if you want to be able to run the tests standalone (i.e. ./test instead of from make check). I've tested this on both RHEL-5 and Fedora-10 machines, and make check works on both, as does running the individual tests by hand.

Re: [libvirt] Xen: Domain.migrate() causes invalid listDomains() output

As there is no alternative to int[] listDomains() (f.e., return UUIDs), I'm stuck here. NB: Doing migration with xm migrate works fine, libvirt isn't confused by that. -t-

[libvirt] [PATCH] Support for IPv6 / multiple ifaces in interface_conf.[ch]

by Laine Stump

This patch updates the xml parsing and formatting, and the associated virInterfaceDef data structure to support IPv6, along the way adding support for multiple protocols per interface, and multiple IP addresses per protocol. Note that netcf appears to not accept defining both ipv4 and ipv6 on the same interface, and still can't report live config of IPv6 (or multiple IPv4 addresses), so the usefulness of this patch is limited until those items are fixed in netcf. This patch applies on top of commit 1ceabc5a152efa8892954cb4f45b85553edfee9f, which I submitted on Sept 28. --- src/conf/interface_conf.c | 308 ++++++++++++++++++++++++++++++++++----------- src/conf/interface_conf.h | 21 +++- 2 files changed, 247 insertions(+), 82 deletions(-) diff --git a/src/conf/interface_conf.c b/src/conf/interface_conf.c index b422464..24f111c 100644 --- a/src/conf/interface_conf.c +++ b/src/conf/interface_conf.c @@ -53,9 +53,32 @@ void virInterfaceBareDefFree(virInterfaceBareDefPtr def) { VIR_FREE(def);

[libvirt] [PATCH] Support reporting live interface IP/netmask.

by Laine Stump

From: root <root(a)vlap.laine.org> This patch adds the flag VIR_INTERFACE_XML_INACTIVE to virInterfaceGetXMLDesc's flags. When it is *not* set (the default), the live interface info will be returned in the XML. in particular, the IP address(es) and netmask(s) will be retrieved by querying the device directly, rather than just reporting what's in the config file. The backend of this is in netcf's new ncf_if_xml_state() function. Any live interface ip address info in the xml will have the property "source" set to "device", eg: <ip address='10.24.0.1' prefix='24' source='device'/> Also, if an interface is currently inactive, no ip addresses will be returned, since an inactive interface device can't be queried for IP addresses (effectively it has none). A difference in the XML from previously - it is now acceptable to have both a dhcp *and* an ip node (or neither) within the protocol node. Before you had to have one or the other, but couldn't have both. Note that you need at least netcf 0.1.2 for this to build and work, and an upcoming release (patches submitted today) for it to work exactly as described above. --- include/libvirt/libvirt.h.in | 4 +++ src/conf/interface_conf.c | 62 ++++++++++++++++++++++------------------- src/conf/interface_conf.h | 1 + src/interface/netcf_driver.c | 8 ++++- src/libvirt.c | 15 +++++++--- tools/virsh.c | 10 +++++- 6 files changed, 63 insertions(+), 37 deletions(-) diff --git a/include/libvirt/libvirt.h.in b/include/libvirt/libvirt.h.in index 4e63e48..fd0c90b 100644 --- a/include/libvirt/libvirt.h.in +++ b/include/libvirt/libvirt.h.in @@ -922,6 +922,10 @@ virInterfacePtr virInterfaceLookupByMACString (virConnectPtr conn, const char* virInterfaceGetName (virInterfacePtr iface); const char* virInterfaceGetMACString (virInterfacePtr iface); +typedef enum { + VIR_INTERFACE_XML_INACTIVE = 1 /* dump inactive interface information */ +} virInterfaceXMLFlags; + char * virInterfaceGetXMLDesc (virInterfacePtr iface, unsigned int flags); virInterfacePtr virInterfaceDefineXML (virConnectPtr conn, diff --git a/src/conf/interface_conf.c b/src/conf/interface_conf.c index e646351..b422464 100644 --- a/src/conf/interface_conf.c +++ b/src/conf/interface_conf.c @@ -92,6 +92,7 @@ void virInterfaceDefFree(virInterfaceDefPtr def) VIR_FREE(def->proto.family); VIR_FREE(def->proto.address); VIR_FREE(def->proto.gateway); + VIR_FREE(def->proto.source); VIR_FREE(def); } @@ -272,6 +273,8 @@ virInterfaceDefParseIp(virConnectPtr conn, virInterfaceDefPtr def, "%s", _("Invalid ip address prefix value")); return(-1); } + tmp = virXPathString(conn, "string(./ip[1]/@source)", ctxt); + def->proto.source = tmp; } tmp = virXPathString(conn, "string(./route[1]/@gateway)", ctxt); def->proto.gateway = tmp; @@ -282,22 +285,19 @@ virInterfaceDefParseIp(virConnectPtr conn, virInterfaceDefPtr def, static int virInterfaceDefParseProtoIPv4(virConnectPtr conn, virInterfaceDefPtr def, xmlXPathContextPtr ctxt) { - xmlNodePtr cur; - int ret; + xmlNodePtr dhcp, ip; + int ret = 0; - cur = virXPathNode(conn, "./dhcp", ctxt); - if (cur != NULL) - ret = virInterfaceDefParseDhcp(conn, def, cur, ctxt); - else { - cur = virXPathNode(conn, "./ip", ctxt); - if (cur != NULL) - ret = virInterfaceDefParseIp(conn, def, cur, ctxt); - else { - virInterfaceReportError(conn, VIR_ERR_XML_ERROR, - "%s", _("interface miss dhcp or ip adressing")); - ret = -1; - } - } + dhcp = virXPathNode(conn, "./dhcp", ctxt); + if (dhcp != NULL) + ret = virInterfaceDefParseDhcp(conn, def, dhcp, ctxt); + + if (ret != 0) + return(ret); + + ip = virXPathNode(conn, "./ip", ctxt); + if (ip != NULL) + ret = virInterfaceDefParseIp(conn, def, ip, ctxt); return(ret); } @@ -1005,6 +1005,7 @@ virInterfaceVlanDefFormat(virConnectPtr conn, virBufferPtr buf, static int virInterfaceProtocolDefFormat(virConnectPtr conn ATTRIBUTE_UNUSED, virBufferPtr buf, const virInterfaceDefPtr def) { + char prefixStr[16]; if (def->proto.family == NULL) return(0); virBufferVSprintf(buf, " <protocol family='%s'>\n", def->proto.family); @@ -1015,20 +1016,23 @@ virInterfaceProtocolDefFormat(virConnectPtr conn ATTRIBUTE_UNUSED, virBufferAddLit(buf, " <dhcp peerdns='yes'/>\n"); else virBufferAddLit(buf, " <dhcp/>\n"); - } else { - /* theorically if we don't have dhcp we should have an address */ - if (def->proto.address != NULL) { - if (def->proto.prefix != 0) - virBufferVSprintf(buf, " <ip address='%s' prefix='%d'/>\n", - def->proto.address, def->proto.prefix); - else - virBufferVSprintf(buf, " <ip address='%s'/>\n", - def->proto.address); - } - if (def->proto.gateway != NULL) { - virBufferVSprintf(buf, " <route gateway='%s'/>\n", - def->proto.gateway); - } + } + if (def->proto.address != NULL) { + if (def->proto.prefix != 0) + snprintf(prefixStr, sizeof(prefixStr), "%d", def->proto.prefix); + + virBufferVSprintf(buf, " <ip address='%s'%s%s%s%s%s%s/>\n", + def->proto.address, + def->proto.prefix ?

[libvirt] [RFC PATCH 0/6] Series short description

by Gerhard Stenzel

The following series of patches is a prototype implementation of a ebtables based MAC address filter. This is currently not intended for inclusion, but rather to get some feedback/comments about the approach and the implementation. At the moment, some defaults are set when libvirtd starts and when a domain is started or destroyed. The plan is to extend this filter capability to the API level and virsh command level. The plan is also to add more filtering features like VLAN filtering and QoS filtering. Thanks, Gerhard --- Gerhard Stenzel (6): remove currently unused parameter to pass make check test add MAC address based port filtering to qemu add MAC address based port filtering to libvirt add the ebtables wrapper to network driver add build support for ebtables wrapper add ebtables wrapper configure.in | 3 include/libvirt/libvirt.h.in | 14 + src/Makefile.am | 1 src/conf/network_conf.h | 10 src/driver.h | 14 + src/libvirt.c | 119 +++++ src/libvirt_private.syms | 26 + src/libvirt_public.syms | 3 src/network/bridge_driver.c | 175 ++++++++ src/qemu/qemu.conf | 3 src/qemu/qemu_conf.c | 14 + src/qemu/qemu_conf.h | 2 src/qemu/qemu_driver.c | 23 + src/test/test_driver.c | 3 src/util/ebtables.c | 961 ++++++++++++++++++++++++++++++++++++++++++ src/util/ebtables.h | 134 ++++++ 16 files changed, 1505 insertions(+), 0 deletions(-) create mode 100644 src/util/ebtables.c create mode 100644 src/util/ebtables.h --

https://bugzilla.redhat.com/show_bug.cgi?id=526769 Current setup is daily with 7 backups so one week worth of logs per domain in /var/log/libvirt/qemu/*.log First a week worth of backup is a bit short, second for most domains the logs are really small, and with 7 backup files this directory gets crowded quickly. This patches changes to weekly, with 4 backups, so always a month worth of logs, and will nearly cut in half the number of entries in that directory.

[libvirt] Regarding connecting to libvirt from windows

by anuj rampal

Hi, I can connect to libvirt over TCP/IP from windows and call all the functions. what i want is to do some kind of authentication like entering some kind of username/password. im using virConnectOpen(const char* name) function. i tried using virConnectOpenAuth().. but whatever parameter ii give it gets connected and there is no option to pass username/password. Thanks in advance. Regards Anuj
