January 2016 - Devel - Libvirt List Archives

by Daniel Veillard

As planned I just tagged the release in git and pushed signed tarball and rpms to the usual place: ftp://libvirt.org/libvirt/ I also tagged and pushed a python release though there is no change from 1.3.0: ftp://libvirt.org/libvirt/python/ This is a moderately large release with close to 300 commits packed in, one security patch for CVE-2015-5313, and some user visible feature improvement. There is also a lot of refactoring in code, makefiles etc along with other improvements and the … [View More]usual flow of bug fixes: Features: - Various improvements for the Xen libxl driver (Jim Fehlig) -

[libvirt] Trying to debug "Received unexpected event 3" from libvirt

by Yaniv Kaul

Hi, I'm trying to debug this issue, which may be affecting my inability to perform live snapshot. 1. I'm not sure what 'Waking up a tragedian" in the debug log means - what exactly is a tragedian? 2. In any case, it'd be great if the WARN would mention mon->await_event - is it the event libvirt is actually waiting for? (Both from qemu/qemu_agent.c) 3. I reckon event 3 is QEMU_AGENT_EVENT_RESET ? (from qemu/qemu_agent.h) 4. I'm also getting 'End of file while reading data: Input/output … [View More]

[libvirt] [PATCH 0/3] Misc fixes

by Cédric Bosdonnat

Hi all, Here are a few patches without strong connection together. The first one only allows us not to package virt-login-shell even with lxc driver enabled. The other ones are related to mounts security. I'm wondering if changing the default dropped capabilities in the lxc driver is acceptable... dropping sys_admin makes sense, but it can introduce incompatibilities for users needing it as they will need to explicitely enable it. Cédric Bosdonnat (3): Allow building lxc without virt-login-… [View More]

[libvirt] [PATCH] security: Do not restore labels on device tree binary

by Jiri Denemark

A device tree binary file specified by /domain/os/dtb element is a read-only resource similar to kernel and initrd files. We shouldn't restore its label when destroying a domain to avoid breaking other domains configure with the same device tree.

[libvirt] [PATCH] Fix make check with gcc version 5

by Martin Kletzander

When building with gcc-5 (particularly gcc-5.3.0 now) and having pdwtags installed (package dwarves) make check fails with the following error: $ make lock_protocol-struct GEN lock_protocol-struct --- lock_protocol-structs 2016-01-13 15:04:59.318809607 +0100 +++ lock_protocol-struct-t3 2016-01-13 15:05:17.703501234 +0100 @@ -26,10 +26,6 @@ virLockSpaceProtocolNonNullString name; u_int flags; }; -enum … [View More]virLockSpaceProtocolAcquireResourceFlags { - VIR_LOCK_SPACE_PROTOCOL_ACQUIRE_RESOURCE_SHARED = 1, - VIR_LOCK_SPACE_PROTOCOL_ACQUIRE_RESOURCE_AUTOCREATE = 2, -}; struct virLockSpaceProtocolAcquireResourceArgs { virLockSpaceProtocolNonNullString path; virLockSpaceProtocolNonNullString name; Makefile:10415: recipe for target 'lock_protocol-struct' failed make: *** [lock_protocol-struct] Error 1 That happens because without any specific options gcc doesn't keep enum information in the resulting binary object. I managed to isolate the parameters of gcc that caused this issue to disappear, however I remember that they influenced the resulting binaries quite a bit and were definitely not something we would want to add as mandatory to the build process. So to deal with this cleanly, let's take that enum and separate it out to its own header file. Since it is only used in the lockd driver and the protocol, lock_driver_lockd.h feels like a suitable name.

[libvirt] [PATCH] security: Do not restore kernel and initrd labels

by Jiri Denemark

Kernel/initrd files are essentially read-only shareable images and thus should be handled in the same way. We already use the appropriate label for kernel/initrd files when starting a domain, but when a domain gets destroyed we would remove the labels which would make other running domains using the same files very unhappy. https://bugzilla.redhat.com/show_bug.cgi?id=921135 Signed-off-by: Jiri Denemark <jdenemar(a)redhat.com> --- src/security/security_dac.c | 8 -------- src/… [View More]

[libvirt] Entering freeze for libvirt-1.3.1

by Daniel Veillard

As suggested this w.e., I just tagged the release candidate 1 in git and pushed signed tarball and rpms to the usual place: ftp://libvirt.org/libvirt/ This works fine with my limited testing, but obviously more people need to give it some trial especially on other platforms. The output from CentOS CI is mostly green which is a good sign with just libvirt-daemon-rpm and virt-manager-test in the red, someone probably need to have a look before we release. The rc2 should come in 2 days … [View More]

[libvirt] Quantifying libvirt errors in launching the libguestfs appliance

by Richard W.M. Jones

As people may know, we frequently encounter errors caused by libvirt when running the libguestfs appliance. I wanted to find out exactly how frequently these happen and classify the errors, so I ran the 'virt-df' tool overnight 1700 times. This tool runs several parallel qemu:///session libvirt connections both creating a short-lived appliance guest. Note that I have added Cole's patch to fix https://bugzilla.redhat.com/1271183 "XML-RPC error : Cannot write data: Transport endpoint is not … [View More]

[libvirt] [REPOST 0/4] Adjustment to recent cgroup/cpuset changes (for 1.3.1)

by John Ferlan

Reposting my cgroup fixes series: http://www.redhat.com/archives/libvir-list/2016-January/msg00236.html partially because I originally forgot to CC the author (Henning Schild) of the original series for which these patch fix a couple of issues discovered during regression testing (virt-test memtune failures in Red Hat regression environment), but also to bring them up to date with the top of libvirt git. NB: I did send Henning the changes after the fact, but my resend using the same message-… [View More]
