I have system with 3.19.3 kernel and libvirt 1.3.3 (version not matter because part of code not changed). When i'm try to get cpu stats via libvirt i have error in libvirt log, that says "cannot parse process status data" relevant code in src/qemu/qemu_driver.c in function qemuGetProcessInfo i'm add debut test to this function and in my case i have always fscanf != 4 qemu pid 7977 cat /proc/7977/stat 7977 (qemu-system-x86) S 1 7976 7976 0 -1 138420608 12728 0 0 0 4819 8249 0 0 20 0 7 0 51378692 4783886336 75779 18446744073709551615 139849472311296 139849478294132 140732912418880 140732912417952 139849400618495 0 268444224 4096 16963 18446744073709551615 0 0 17 5 0 0 15624 744 0 139849480394624 139849482248448 139849496641536 140732912421083 140732912422775 140732912422775 140732912422876 0 cat /proc/7977/task/7977/stat 7977 (qemu-system-x86) S 1 7976 7976 0 -1 138420608 12537 0 0 0 3917 7799 0 0 20 0 7 0 51378692 4783886336 75779 18446744073709551615 139849472311296 139849478294132 140732912418880 140732912417952 139849400618495 0 268444224 4096 16963 0 0 0 17 3 0 0 15624 0 0 139849480394624 139849482248448 139849496641536 140732912421083 140732912422775 140732912422775 140732912422876 0 cat /proc/7977/task/7979/stat 7979 (qemu-system-x86) S 1 7976 7976 0 -1 1077944384 20 0 0 0 0 0 0 0 20 0 7 0 51378696 4783886336 75779 18446744073709551615 139849472311296 139849478294132 140732912418880 139849260591832 139849400637449 0 2147221247 4096 16963 0 0 0 -1 6 0 0 0 0 0 139849480394624 139849482248448 139849496641536 140732912421083 140732912422775 140732912422775 140732912422876 0 cat /proc/7977/task/7982/stat 7982 (CPU 0/KVM) S 1 7976 7976 0 -1 138420416 22 0 0 0 226 118 0 0 20 0 7 0 51378697 4783886336 75779 18446744073709551615 139849472311296 139849478294132 140732912418880 139849222842936 139849400624151 0 2147220671 4096 16963 0 0 0 -1 5 0 0 0 196 0 139849480394624 139849482248448 139849496641536 140732912421083 140732912422775 140732912422775 140732912422876 0 Does somebody have time to fix this ? -- Vasiliy Tolstov, e-mail: v.tolstov(a)yoctocloud.net

[libvirt] qemu: cpu model definition problem
by Maxim Nestratov 21 Jun '16

21 Jun '16

Hi all, I've just encountered a problem with ability to live migrate a VM between hosts using the following cpu section in VM's xml: <cpu mode='custom' match='exact'> <model fallback='allow'>Haswell-noTSX</model> ... <feature policy='disable' name='rdrand'/> </cpu> The problem is that a VM with such a config crashes when it migrates from a host where 'rdrand' presents to a host where it is absent. This happens due to the fact that QEMU and libvirt have pretty different view on what 'Haswell-noTSX' is. Libvirt's description lacks some features, which present in QEMU description of this cpu model (e.g. 'rdrand'). It is impossible to disable features present on the host and different from QEMU's ones by current libvirt code, i.e. libvirt thinks that no use to disable something that doesn't exist. Of course, the problem in this case can be fixed just by adding missed features to 'Haswell-noTSX' model in cpu_map.xml to match what QEMU has, but it doesn't seem right because it will help just in this particular case, and in general, it will not be a solution because QEMU can change its cpu model definitions at any time and it does this from time to time. What libvirt might have done is: - either ask QEMU for cpu model definition and work with it, - or construct a command line for QEMU with required and disabled features without taking into account libvirt cpu_map.xml, i.e. always add '+xx' and '-yy' for features mentioned explicitly in domain xml. What do you think? Maxim

[libvirt] [PATCH] conf: limit chassisNr, and busNr to a minimum value of 1, not 0
by Laine Stump 21 Jun '16

21 Jun '16

In the case of chassisNr (used to set chassis_nr of a pci-bridge controller), 0 is reserved for / used by the pci[e]-root bus. In the base of busNr, a value of 0 would mean that the root bus had no places available to plug in new buses, including the pxb itself (the documentation I wrote for pxb even noted the limit of busNr as 1.254). NB: oddly, the "chassis" attribute, which is used for pcie-root-port and pcie-switch-downstream-port *can* be set to 0, since it's the combination of {chassis, slot} that needs to be unique, not chassis by itself (and slot 0 of pcie-root is reserved, while pcie-*-port can use *only* slot 0).

[libvirt] gnulib and 32-bit libvirt build, rpl_canonicalize_file_name
by Ian Jackson 20 Jun '16

20 Jun '16

The Xen Project's automated test (CI) system has reported a build failure in libvirt; libvirt uses gnulib. osstest has bisected it to a specific gnulib commit. (Email from osstest is quoted below.) The error message is: ../gnulib/lib/.libs/libgnu.a(canonicalize-lgpl.o): In function `rpl_canonicalize_file_name': /home/osstest/build.95966.build-i386-libvirt/libvirt/gnulib/lib/canonicalize-lgpl.c:400: multiple definition of `rpl_canonicalize_file_name' .libs/virpcimock_la-virpcimock.o:/home/osstest/build.95966.build-i386-libvirt/libvirt/tests/virpcimock.c:954: first defined here collect2: error: ld returned 1 exit status Do you already know about this ? Would you like us to submit a patch to gnulib ?

[libvirt] [PATCH] qemu: Don't use legacy USB for aarch64 mach-virt guests
by Andrea Bolognani 20 Jun '16

20 Jun '16

The '-usb' option doesn't have any effect for aarch64 mach-virt guests, so the fact that it's currently enabled by default is not really causing any issue. However, that might change in the future (although unlikely), and having it as part of the QEMU command line can cause confusion to someone looking through the process list. Avoid it completely, like it's already happening for q35. --- This requires https://www.redhat.com/archives/libvir-list/2016-June/msg01157.html to apply cleanly, but it's not really related. Applying it on top of master instead should just be a matter of fixing a few trivial merge conflicts in the test suite. CC:ing Drew for extra assurance that doing this is indeed completely safe :) src/qemu/qemu_command.c | 1 + tests/qemuxml2argvdata/qemuxml2argv-aarch64-aavmf-virtio-mmio.args | 1 -

(CCing libvirt list) As we shouldn't make machine-type changes introduce new host requirements, it looks like we need to either add a new set of CPU models (unreasonable), or expect management software to explicitly enable LMCE after ensuring the host supports it. Or we could wait for a reasonable time after the feature is available in the kernel, and declare that QEMU as a whole requires a newer kernel. But how much time would be reasonable for that? Long term, I believe we should think of a better solution. I don't think it is reasonable to require new libvirt code to be written for every single low-level feature that requires a newer kernel or newer host hardware. Maybe new introspection interfaces that would allow us to drop the "no new requirements on machine-type changes" rule? -- Eduardo

[libvirt] Question: forbid dnsmasq to install IPv6 default route
by Maxim Perevedentsev 18 Jun '16

18 Jun '16

Hello guys! I got into problem with installing IPv6 default gateway on centos7 guest while running dhcpv6. === Scheme === Guest has two network interfaces. *eth0* is connected to Host-Only network over virbr0. This network has dhcpv6 set up. [root@s143 ~]# virsh net-dumpxml Host-Only <network connections='1'> <name>Host-Only</name> <uuid>11aa4e6a-9014-4dae-86b9-b13159896efe</uuid> <bridge name='virbr0' stp='off' delay='0'/> <mac address='52:54:00:1e:17:49'/> <ip family='ipv4' address='10.37.130.2' prefix='24'> <dhcp> <range start='10.37.130.1' end='10.37.130.254'/> </dhcp> </ip> <ip family='ipv6' address='fdb2:2c26:f4e4::1' prefix='64'> <dhcp> <range start='fdb2:2c26:f4e4::' end='fdb2:2c26:f4e4::ffff'/> </dhcp> </ip> </network> *eth1* is connected to Bridged network over br0 bridge on host enp4s0 interface. [root@s143 ~]# virsh net-dumpxml Bridged <network connections='1'> <name>Bridged</name> <uuid>1ffa16f9-6a52-4710-9b58-52b8463cdece</uuid> <forward mode='bridge'/> <bridge name='br0'/> </network> [root@s143 ~]# virsh iface-dumpxml br0 <interface type='bridge' name='br0'> <protocol family='ipv4'> <ip address='10.94.1.161' prefix='16'/> </protocol> <protocol family='ipv6'> <ip address='2001:aaad::a5e:a28E' prefix='64'/> <ip address='fe80::be5f:f4ff:fe44:2cbb' prefix='64'/> </protocol> <bridge> <interface type='ethernet' name='vme42460d71'> <link state='unknown'/> <mac address='fe:1c:42:46:0d:71'/> </interface> <interface type='ethernet' name='enp4s0'> <link speed='1000' state='up'/> <mac address='bc:5f:f4:44:2c:bb'/> </interface> </bridge> </interface> === Problem === Now I want to set ipv6 address 2001:aaad::a5e:a28F to guest eth1 (bridged to host) and install a default route ip -6 route add default via 2001:aaad::a5e:a290 dev eth1 // metric 1024 So I want all the IPv6 traffic w/o route to go into eth1, then through host bridge to gateway (same for host and guest). The problem is that I see following in my guest: // the metric changes somehow, but this does not matter. default via fe80::5054:ff:fe1e:1749 dev eth0 proto static metric 100 pref medium default via 2001:aaad::a5e:a290 dev eth1 metric 1024 pref medium And the first (via link-local) route is preferred on routing. [root@s143 ~]# ip -6 address show dev virbr0 6: virbr0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 inet6 fdb2:2c26:f4e4::1/64 scope global valid_lft forever preferred_lft forever inet6 fe80::5054:ff:fe1e:1749/64 scope link valid_lft forever preferred_lft forever The problem is: guest:/ # radvdump # # radvd configuration generated by radvdump 2.11 # based on Router Advertisement from fe80::5054:ff:fe1e:1749 # received by interface eth0 # interface eth0 { AdvSendAdvert on; # Note: {Min,Max}RtrAdvInterval cannot be obtained with radvdump AdvManagedFlag on; AdvOtherConfigFlag on; AdvReachableTime 0; AdvRetransTimer 0; AdvCurHopLimit 64; AdvDefaultLifetime 1800; <---------------- AdvHomeAgentFlag off; AdvDefaultPreference medium; AdvLinkMTU 1500; AdvSourceLLAddress on; prefix fdb2:2c26:f4e4::/64 { AdvValidLifetime 3600; AdvPreferredLifetime 3600; AdvOnLink on; AdvAutonomous off; AdvRouterAddr off; }; # End of prefix definition RDNSS fe80::5054:ff:fe1e:1749 { AdvRDNSSLifetime 3600; }; # End of RDNSS definition }; # End of interface definition So, dnsmasq includes its link-local address into RA and announces itself as default gateway valid for 30min. Guest sees this RA and installs a route in accordance. As a result, the default gateway requested by user is overridden and thus not used. We cannot just disable RA since we still need IPv6 address on guest eth0 (dhcp6 part of functionality). === Possible solutions === I see two possible solutions. 1) Tinker with routes. As I said, the metric of installed RA routes may change and it's difficult to override them for sure (maybe with metric 0 or 1?) Moreover, this may confuse user and requires specific knowledge (IPv6, RA, etc.). 2) Forbid guest to learn default route from RA sysctl -w net.ipv6.conf.eth0.accept_ra_defrtr=0 - This should be made for all virbr-based networks. - This may confuse user as well. 3) Forbid dnsmasq to announce virbr0 link-local address as default gateway. This can be made with adding 'ra-param=*,0,0' to /var/lib/libvirt/dnsmasq/Host-Only.conf // interface=* (any), interval=0 (default), router_lifetime=0 (I am NOT you gateway, Luke). // tested on dnsmasq-2.75-3.fc22 but should work from 2.67 now the RA looks as following: linux-bnqo:/ # radvdump # # radvd configuration generated by radvdump 2.11 # based on Router Advertisement from fe80::5054:ff:fe1e:1749 # received by interface eth0 # interface eth0 { AdvSendAdvert on; # Note: {Min,Max}RtrAdvInterval cannot be obtained with radvdump AdvManagedFlag on; AdvOtherConfigFlag on; AdvReachableTime 0; AdvRetransTimer 0; AdvCurHopLimit 64; AdvDefaultLifetime 0; AdvHomeAgentFlag off; AdvDefaultPreference medium; AdvLinkMTU 1500; AdvSourceLLAddress on; prefix fdb2:2c26:f4e4::/64 { AdvValidLifetime 3600; AdvPreferredLifetime 3600; AdvOnLink on; AdvAutonomous off; AdvRouterAddr off; }; # End of prefix definition RDNSS fe80::5054:ff:fe1e:1749 { AdvRDNSSLifetime 3600; }; # End of RDNSS definition }; # End of interface definition === Conclusion ==== Please correct me if my setup itself is wrong and causes problems. Maybe there are another solutions possible, w/o modifying libvirt/guest? Would you accept patches related to 3rd solution? Looking forward to your replies. Thanks in advance! -- Your sincerely, Maxim Perevedentsev

[libvirt] [PATCH 1/2] Add new elements source, access and allocation
by Safka, JaroslavX 17 Jun '16

17 Jun '16

This change introduces support for preallocated shared file descriptor based memory backing. It allows vhost-user to be used without hugepages. This is achieved by introducing 3 new sub elements to the memoryBacking element: source, access & allocation which will configure qemu commandline during VM startup accordingly. First patch adds parsing of elements and storing the values in mem structure. Second patch configures the qemu commandline on the base of values in mem structure. -------------------------------------------------------------- Intel Research and Development Ireland Limited Registered in Ireland Registered Office: Collinstown Industrial Park, Leixlip, County Kildare Registered Number: 308263 This e-mail and any attachments may contain confidential material for the sole use of the intended recipient(s).

Patches that allowed to use memory hotplug without NUMA introduced a problem where the size in <memory> wouldn't be right after memory cold unplug. See patch 1/2 for explanation.

[libvirt] [PATCH v2] util: Make failure to get suplementary group list for a uid non-fatal
by Peter Krempa 16 Jun '16

16 Jun '16

Since introduction of the DAC security driver we've documented that seclabels with a leading + can be used with numerical uid. This would not work though with the rest of libvirt if the uid was not actually used in the system as we'd fail when trying to get a list of suplementary groups for the given uid. Since a uid without entry in /etc/passwd (or other user database) will not have any suppolementary groups we can treat the failure to obtain them as such. This patch modifies virGetGroupList to not report the error of missing user and tweaks callers to treat the missing list as having 0 supplementary groups. The only place reporting errors is virt-login-shell as it's used to determine whether the given user is allowed to access the shell. --- Although it was ACKed I'm reposting a rebased version including the fixes and fixed merge conflicts. I'd like to hear feedback from the reporter of this issue.

[libvirt] [PATCH v4 0/3] qemu: expand domain memory statistics
by Derbyshev Dmitriy 16 Jun '16

16 Jun '16

From: Derbyshev Dmitry <dderbyshev(a)virtuozzo.com> QEMU reports timestamp and available along with other memory statistics. This information was not saved into domain statistics. Also, to collect all balloon statistics for all guests it was necessary to make several libvirt requests (one per VE). Last patch allows doing this via qemuConnectGetAllDomainStats in one request. Changes since v1: * Enum numeration fixed * Macro getting "usage" field fixed Changes since v2: * previous patches were on wrong branch * qemu's stat name was "stat-available-memory" Changes since v3: * 3rd patch added Derbyshev Dmitry (3): qemu: expand domain memory statistics with 'usable' qemu: expand domain memory statistics with 'last-update' timestamp qemu: return balloon statistics alongside all domain stats include/libvirt/libvirt-domain.h | 11 +++++- src/libvirt-domain.c | 5 +++ src/qemu/qemu_driver.c | 84 +++++++++++++++++++++++++++++++--------- src/qemu/qemu_monitor_json.c | 22 ++++++----- tools/virsh-domain-monitor.c | 4 ++ 5 files changed, 98 insertions(+), 28 deletions(-) -- 1.9.5.msysgit.0

[libvirt] [PATCH] xenconfig: fix conversion of <driver> to backendtype
by Jim Fehlig 16 Jun '16

16 Jun '16

When converting domXML to xen xl.cfg, backendtype should not be emitted if <driver> is not specified. Moreover, <driver name='file'/> should be converted to backendtype qdisk, similar to handling of <driver> in libxlMakeDisk() in libxl_conf.c. Prior to this change, connectDomainXMLToNative would produce incorrect xl.cfg when the input domXML contained <driver name='file'/> domXML: <disk type="file" device="disk"> <driver name="file"/> <source file="/image/file/path"/> <target dev="xvda" bus="xen"/> </disk> virsh domxml-to-native xen-xl domXML disk = [ "format=raw,vdev=xvda,access=rw,backendtype=target=/image/file/path" ] xl create xl.cfg config parsing error in disk specification: unknown value for backendtype: near `target=/image/file/path' in `format=raw,vdev=xvda,access=rw,backendtype=target=/image/file/path' Signed-off-by: Jim Fehlig <jfehlig(a)suse.com> --- src/xenconfig/xen_xl.c | 16 +++++++++------- 1 file changed, 9 insertions(+), 7 deletions(-) diff --git a/src/xenconfig/xen_xl.c b/src/xenconfig/xen_xl.c index 5879c66..d524a82 100644 --- a/src/xenconfig/xen_xl.c +++ b/src/xenconfig/xen_xl.c @@ -857,13 +857,15 @@ xenFormatXLDisk(virConfValuePtr list, virDomainDiskDefPtr disk) } /* backendtype */ - virBufferAddLit(&buf, "backendtype="); - if (STREQ_NULLABLE(driver, "qemu")) - virBufferAddLit(&buf, "qdisk,"); - else if (STREQ_NULLABLE(driver, "tap")) - virBufferAddLit(&buf, "tap,"); - else if (STREQ_NULLABLE(driver, "phy")) - virBufferAddLit(&buf, "phy,"); + if (driver) { + virBufferAddLit(&buf, "backendtype="); + if (STREQ(driver, "qemu") || STREQ(driver, "file")) + virBufferAddLit(&buf, "qdisk,"); + else if (STREQ(driver, "tap")) + virBufferAddLit(&buf, "tap,"); + else if (STREQ(driver, "phy")) + virBufferAddLit(&buf, "phy,"); + } /* devtype */ if (disk->device == VIR_DOMAIN_DISK_DEVICE_CDROM) -- 2.1.4

[libvirt] [PATCH] util: fix missing broadcast address in bridge and tap device IP addresses
by Laine Stump 16 Jun '16

16 Jun '16

Commit b3d069872ce53eb added peer address setting to the low level virNetDevSetIPAddress() function, but ended up causing a segfault in cases where the caller passed NULL for peer address. Commit a3510e33d33e52c fixed the segfault, but managed to cause us to skip setting the broadcast address when setting an interface's IP address if the peer address was NULL. The result is that the broadcast address is 0.0.0.0 for all libvirt-created bridges (and for now also in interfaces in lxc containers with IP addresses set by libvirt). This was reported on the mailing list: https://www.redhat.com/archives/libvir-list/2016-June/msg00027.html but I was too busy to investigate at the time. I found it by accident today while refactoring virNetDevSetIPAddress(). Since this regression is present in the 1.3.5 release, I'm sending the bugfix as a separate simpler patch from my larger refactoring patchset. --- src/util/virnetdev.c | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) diff --git a/src/util/virnetdev.c b/src/util/virnetdev.c index 925b41f..5a4ccc6 100644 --- a/src/util/virnetdev.c +++ b/src/util/virnetdev.c @@ -1129,7 +1129,8 @@ int virNetDevSetIPAddress(const char *ifname, unsigned int recvbuflen; /* The caller needs to provide a correct address */ - if (VIR_SOCKET_ADDR_FAMILY(addr) == AF_INET && peer && !VIR_SOCKET_ADDR_VALID(peer)) { + if (VIR_SOCKET_ADDR_FAMILY(addr) == AF_INET && + !(peer && VIR_SOCKET_ADDR_VALID(peer))) { /* compute a broadcast address if this is IPv4 */ if (VIR_ALLOC(broadcast) < 0) return -1; -- 2.4.11
