[libvirt] [PATCH] qemu: Set arch to i686 if qemu-system-i386 is found
by Guido Günther 19 Oct '12

19 Oct '12

If we can't probe the architecture from QMP we parse the architecture from the qemu binaries name. This results in the architecture being i386 instead of i686 which then results in QEMU_CAPS_PCI_MULTIBUS being unset which gives a broken qemu command line. This probably didn't show up earlier since most of the time there's also a /usr/bin/qemu around which results in i686 capabilities. --- src/qemu/qemu_capabilities.c | 2 ++ 1 file changed, 2 insertions(+) diff --git a/src/qemu/qemu_capabilities.c b/src/qemu/qemu_capabilities.c index 7c391b3..e897f86 100644 --- a/src/qemu/qemu_capabilities.c +++ b/src/qemu/qemu_capabilities.c @@ -2055,6 +2055,8 @@ qemuCapsInitHelp(qemuCapsPtr caps) /* For historical compat we use 'itanium' as arch name */ if (STREQ(tmp, "ia64")) tmp = "itanium"; + else if (STREQ(tmp, "i386")) + tmp = "i686"; } else { uname_normalize(&ut); tmp = ut.machine; -- 1.7.10.4

help to create disk images copy-storage-* required, try to do non-shared migration without bothering to create disk images at target by hand. consider this situation: 1. non-shared migration virsh migrate --copy-storage-all ... 2. migration fails 3. create disk images required qemu-img create ... 4 migration run smoothly so, try do remove step 2, 3, 4 this kind of use had been discussed before, http://www.redhat.com/archives/libvir-list/2011-December/msg00451.html It did not handle more about complete situations suggested by Daniel P.

[libvirt] [PATCH v3 4/4] qemu-config: Add new -add-fd command line option
by Corey Bryant 18 Oct '12

18 Oct '12

This option can be used for passing file descriptors on the command line. It mirrors the existing add-fd QMP command which allows an fd to be passed to QEMU via SCM_RIGHTS and added to an fd set. This can be combined with commands such as -drive to link file descriptors in an fd set to a drive: qemu-kvm -add-fd fd=3,set=2,opaque="rdwr:/path/to/file" -add-fd fd=4,set=2,opaque="rdonly:/path/to/file" -drive file=/dev/fdset/2,index=0,media=disk This example adds dups of fds 4 and 5, and the accompanying opaque strings to the fd set with ID=2. qemu_open() already knows how to handle a filename of this format. qemu_open() searches the corresponding fd set for an fd and when it finds a match, QEMU goes on to use a dup of that fd just like it would have used an fd that it opened itself.

[libvirt] [PATCHv2 00/16] qemu block-commit support
by Eric Blake 18 Oct '12

18 Oct '12

I figured I'd better post this now, while I still iron out the remaining kinks in my SELinux handling (but I'm certainly a lot closer, now that I have libvirt actually identifying which files need the temporary SELinux labels). With this, you can now do things like 'virsh blockcommit $dom $disk --top relative_name --shallow' even when the backing chain refers to an absolute backing file name; the QMP command passed to qemu will have the correct absolute names. Patches 1-6: practically unchanged since v1, although not reviewed yet https://www.redhat.com/archives/libvir-list/2012-October/msg00075.html Patches 7-13: new to this series Patches 14-15: minor changes since v1 ACKs; see details in each commit https://www.redhat.com/archives/libvir-list/2012-October/msg00089.html Patch 16: new to this series Also available at: http://repo.or.cz/w/libvirt/ericb.git/shortlog/refs/heads/blockjob git fetch git://repo.or.cz/libvirt/ericb.git blockjob Eric Blake (16): storage: list more file types storage: treat 'aio' like 'raw' at parse time storage: match RNG to supported driver types storage: use enum for default driver type storage: use enum for disk driver type storage: use enum for snapshot driver type storage: don't probe non-files storage: get entire metadata chain in one call storage: don't require caller to pre-allocate metadata struct storage: remember relative names in backing chain storage: make it easier to find file within chain storage: cache backing chain while qemu domain is live storage: use cache to walk backing chain blockjob: manage qemu block-commit monitor command blockjob: wire up online qemu block-commit blockjob: implement shallow commit flag in qemu docs/schemas/domaincommon.rng | 27 +- docs/schemas/domainsnapshot.rng | 2 +- src/conf/capabilities.h | 4 +- src/conf/domain_conf.c | 160 ++++-------- src/conf/domain_conf.h | 8 +- src/conf/snapshot_conf.c | 23 +- src/conf/snapshot_conf.h | 2 +- src/conf/storage_conf.c | 15 +- src/libvirt.c | 2 - src/libvirt_private.syms | 1 + src/libxl/libxl_conf.c | 42 ++-- src/libxl/libxl_driver.c | 6 +- src/qemu/qemu_capabilities.c | 3 + src/qemu/qemu_capabilities.h | 1 + src/qemu/qemu_cgroup.c | 12 +- src/qemu/qemu_command.c | 18 +- src/qemu/qemu_domain.c | 40 ++- src/qemu/qemu_domain.h | 3 + src/qemu/qemu_driver.c | 236 +++++++++++------ src/qemu/qemu_hotplug.c | 9 +- src/qemu/qemu_monitor.c | 30 +++ src/qemu/qemu_monitor.h | 7 + src/qemu/qemu_monitor_json.c | 34 +++ src/qemu/qemu_monitor_json.h | 7 + src/qemu/qemu_process.c | 23 ++ src/security/security_dac.c | 7 - src/security/security_selinux.c | 11 - src/security/virt-aa-helper.c | 27 +- src/storage/storage_backend_fs.c | 15 +- src/util/storage_file.c | 279 ++++++++++++++++----- src/util/storage_file.h | 43 ++-- src/vbox/vbox_tmpl.c | 6 +- src/xenxs/xen_sxpr.c | 26 +- src/xenxs/xen_xm.c | 28 ++- tests/sexpr2xmldata/sexpr2xml-curmem.xml | 2 +- .../sexpr2xml-disk-block-shareable.xml | 2 +- .../sexpr2xml-disk-drv-blktap-raw.xml | 2 +- .../sexpr2xml-disk-drv-blktap2-raw.xml | 2 +- 38 files changed, 773 insertions(+), 392 deletions(-) -- 1.7.11.7

[libvirt] [PATCH] network: Set to NULL after virNetworkDefFree()
by Michal Privoznik 18 Oct '12

18 Oct '12

which frees all allocated memory but doesn't set the passed pointer to NULL. Therefore, we must do it ourselves. This is causing actual libvirtd crash: Basically, when doing 'virsh net-edit' the newDef should be dropped. And the memory is freed, indeed. However, the pointer is not set to NULL but kept instead. And the next duo of calls 'virsh net-start' and 'virsh net-destroy' starts the disaster. The latter one does the same as 'virsh destroy'; it sees that newDef is nonNULL so it replaces def with newDef (which has been freed already as said a few lines above). Therefore any subsequent call accessing def will hit the ground. --- src/conf/network_conf.c | 3 ++- 1 files changed, 2 insertions(+), 1 deletions(-) diff --git a/src/conf/network_conf.c b/src/conf/network_conf.c index 891d48c..0f7470d 100644 --- a/src/conf/network_conf.c +++ b/src/conf/network_conf.c @@ -260,8 +260,9 @@ virNetworkObjAssignDef(virNetworkObjPtr network, return -1; } } else if (!live) { - virNetworkDefFree(network->newDef); /* should be unnecessary */ + virNetworkDefFree(network->newDef); virNetworkDefFree(network->def); + network->newDef = NULL; network->def = def; } else { virReportError(VIR_ERR_OPERATION_INVALID, -- 1.7.8.6
