[libvirt] [PATCH] virsh: report 0-length active block-commit job status
by Eric Blake 03 Feb '15

03 Feb '15

At least with live block commit, it is possible to have a block job that reports 0 status: namely, when the active image contains no sectors that differ from the backing image it is being committed into [1]. I'm not sure if that represents a qemu bug, but it leads to weird virsh output where 'virsh blockjob $dom vda' has no output during a no-op commit job. It appears that the special case for a zero total was first introduced for migration, where it does sort of make sense (when we do storage migration, the job is broken up into two pieces where the first half of migrating storage has no clue what the total length of the second phase will be, and where qemu migration always reports a non-zero total length but only once we complete the first phase to start actual migration), but it doesn't seem to make sense for any of the block jobs.

[libvirt] Looking for Outreachy sponsors for QEMU, libvirt, and KVM internships (was Outreach Program for Women)
by Stefan Hajnoczi 03 Feb '15

03 Feb '15

Outreach Program for Women is renaming to Outreachy. The new website is: http://outreachy.org/ What is Outreachy? Outreachy helps people from underrepresented groups join the open source community through a 12-week full-time paid internship. The format is similar to Google Summer of Code. Instead of funding university students the focus is on funding women (cis and trans), trans men, and genderqueer people. Last year QEMU participated with one intern, Maria, who developed a qcow2 image format fuzzer to find input validation bugs in QEMU's qcow2 block driver. GNOME, the Linux kernel community, and other projects have also been participating successfully for years. What is the level of sponsorship? Sponsorship is $6,500 per intern. Sponsors can choose their mentor if desired, otherwise we have experienced mentors who can participate. If your company wants to be active in growing the open source community, this is a great way to engage without administrating your own internship program! Dates: * Funding commitment: Monday, February 16 * Participating orgs announced: February 17 * Application deadline for interns: March 24 * Internship dates: May 25 to August 25 Sponsors are listed for recognition on the Outreachy website and can promote job openings. How do QEMU, libvirt, and KVM participate? We try to participate in both Outreachy and Google Summer of Code each year. QEMU acts as an umbrella organization for libvirt and KVM. We have experienced mentors and are able to add new mentors who are active contributors to QEMU, libvirt, or KVM. Full info for organizations: https://wiki.gnome.org/Outreachy/Admin/InfoForOrgs Please let me know if you have any questions. Stefan

[libvirt] [PATCH 0/8] qemu: support setting device's boot order when VM is running
by Wang Rui 03 Feb '15

03 Feb '15

QEMU supported to set device's boot index online recently(since QEMU 2.2.0). http://lists.gnu.org/archive/html/qemu-devel/2014-10/msg00879.html The QMP "qom-set" is available for setting boot index. qom-set's example is as follows: { .name = "qom-set", .args_type = "path:s,property:s,value:q", .mhandler.cmd_new = qmp_qom_set, } (qemu) qom-set nic1 bootindex 3 (qemu) qom-set nic1 bootindex -1 (qemu) qom-set scsi0-0-0-0 bootindex 2 Setting boot index to -1 means cancel it. We can attach/update a device and set it's boot order when VM is running. The boot order will take effect immediately(after guest rebooting). For example, we can use 'virsh update-device' to change an interface's boot order. The xml is specified as below. <interface type='bridge'> <mac address='fa:16:3e:2e:d4:3d'/> <source bridge='br0'/> <target dev='tap4f2bce78-5b'/> <model type='virtio'/> <driver queues='4'/> <boot order='2'/> <alias name='net0'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x03' function='0x0'/> </interface> If the 'boot order' is not specified in the xml, that means canceling its boot order.

[libvirt] Missing libxl_device_nic settings
by Kim Larry 02 Feb '15

02 Feb '15

Hi, I was trying to pass ip address to scripts/vif-bridge by putting <ip address=""/> in guest config xml file, however, I found that libxlMakeNic(which located in libxl/libxl_conf.c:956) doesn't set x_nic->ip. So I patched myself but I'm not so sure about VIR_DOMAIN_NET_TYPE_ETHERNET. It seems like vif-route, correct? Here is my patch: diff --git a/src/libxl/libxl_conf.c b/src/libxl/libxl_conf.c index 0555b91..0effc59 100644 --- a/src/libxl/libxl_conf.c +++ b/src/libxl/libxl_conf.c @@ -1047,10 +1047,18 @@ libxlMakeNic(virDomainDefPtr def, if (VIR_STRDUP(x_nic->bridge, virDomainNetGetActualBridgeName(l_nic)) < 0) return -1; - /* fallthrough */ + if (VIR_STRDUP(x_nic->script, l_nic->script) < 0) + return -1; + if (VIR_STRDUP(x_nic->ip, l_nic->data.bridge.ipaddr) < 0) + return -1; + break; case VIR_DOMAIN_NET_TYPE_ETHERNET: if (VIR_STRDUP(x_nic->script, l_nic->script) < 0) return -1; + if (VIR_STRDUP(x_nic->ip, l_nic->data.ethernet.ipaddr) < 0) + return -1; + if (VIR_STRDUP(x_nic->gatewaydev, l_nic->data.ethernet.dev) < 0) + return -1; break; case VIR_DOMAIN_NET_TYPE_NETWORK: { Regards, Jihoon

[libvirt] [PATCH] Make tests independant of system page size
by Daniel P. Berrange 02 Feb '15

02 Feb '15

Some code paths have special logic depending on the page size reported by sysconf, which in turn affects the test results. We must mock this so tests always have a consistent page size. --- src/libvirt_private.syms | 2 ++ src/openvz/openvz_util.c | 5 +---- src/qemu/qemu_command.c | 4 ++-- src/qemu/qemu_driver.c | 6 +----- src/util/virfile.c | 2 +- src/util/virnuma.c | 6 +++--- src/util/virutil.c | 13 +++++++++++++ src/util/virutil.h | 3 +++ src/xen/xen_hypervisor.c | 4 ++-- tests/qemuxml2argvmock.c | 13 +++++++++++++ tests/qemuxml2argvtest.c | 1 + 11 files changed, 42 insertions(+), 17 deletions(-) diff --git a/src/libvirt_private.syms b/src/libvirt_private.syms index bd7870f..aa68797 100644 --- a/src/libvirt_private.syms +++ b/src/libvirt_private.syms @@ -2215,6 +2215,8 @@ virGetListenFDs;
