I've given this quite a bit more testing today. It works fine qemu-kvm 1.0 -> qemu-2.0+patch (cirrus vga) It works fine qemu-2.0+patch -> qemu-2.0+patch (cirrus vga) It doesn't (yet) work qemu-2.0+patch -> qemu-kvm 1.0 (cirrus vga). The reason for this is (at least) that I need to emulate the broken versioning of the mc146818rtc timer section, as writing it correctly confuses qemu-kvm 1.0. Therefore please don't bother testing migration back to 1.0 yet. -- Alex Bligh

[libvirt] [PATCH] Perform disk config validity checking for attach-device config
by John Ferlan 04 Aug '14

04 Aug '14

https://bugzilla.redhat.com/show_bug.cgi?id=1078126 Using 'virsh attach-device --config' (or --persistent) to attach a file backed lun device will succeed; however, subsequent domain restarts will result in failure because the configuration of a file backed lun is not supported. Although allowing 'illegal configurations' is something that can be allowed, it may not be practical in this case. Generally, when attaching a device to a domain means the domain must be running. A way around this is using the --config (or --persistent) option. When an attach is done to a running domain, a temporary configuration is modified first followed by the live update. The live update will make a number of disk validity checks when building the qemu command to attach the disk. If any fail, then change is rejected. Rather than allow a potentially illegal combination, adjust the code in the configuration path to make the same checks as the running path will make with respect to disk validity checks. This way we avoid having the potential for some subsequent start/reboot to fail because an illegal combination was allowed. NB: The live checking remains since it is possible to just to --live configuration modification.

[libvirt] [PATCH v2] storage: Refresh storage pool after upload
by John Ferlan 04 Aug '14

04 Aug '14

https://bugzilla.redhat.com/show_bug.cgi?id=1072653 Upon successful upload of a volume, the target volume and storage pool were not updated to reflect any changes as a result of the upload. Make use of the existing stream close callback mechanism to force a backend pool refresh to occur in a separate thread once the stream closes. The separate thread should avoid potential deadlocks if the refresh needed to wait on some event from the event loop which is used to perform the stream callback. Signed-off-by: John Ferlan <jferlan(a)redhat.com> --- Update since v1 - as discussed in original posting, use virThreadCreate to generate a thread to handle the refresh callback: http://www.redhat.com/archives/libvir-list/2014-July/msg01395.html Avoid the Free callback function and have the thread do the memory free as long as thread creation was successful. Thus a couple of changes to function names were appropriate. Understood that this can wait for 1.2.8 - figured to get it ready to go NOTE: Still used pool refresh, since I found that without this patch applied a pool-dumpxml displayed the same allocation/available before and after the upload, so that data is not refreshed for each call as was my concern over using refreshVol vs. refreshPool # virsh pool-dumpxml default ... <allocation unit='bytes'>33852141568</allocation> <available unit='bytes'>110510419968</available> ... # virsh vol-upload test-qcow2-4g.img test.img default # virsh pool-dumpxml default ... <allocation unit='bytes'>33852141568</allocation> <available unit='bytes'>110510419968</available> ... # src/libvirt.c | 8 ++++ src/libvirt_private.syms | 1 + src/storage/storage_driver.c | 103 +++++++++++++++++++++++++++++++++++++++++++ tools/virsh.pod | 3 ++ 4 files changed, 115 insertions(+) diff --git a/src/libvirt.c b/src/libvirt.c index 143d319..992e4f2 100644 --- a/src/libvirt.c +++ b/src/libvirt.c @@ -13960,6 +13960,14 @@ virStorageVolDownload(virStorageVolPtr vol, * detect any errors.

[libvirt] [PATCH] domtop: Turn parse_argv into void
by Michal Privoznik 04 Aug '14

04 Aug '14

Currently, the function follows the usual pattern used in our code: int ret = -1; ... ret = 0; cleanup: return ret; However, the function always call exit() on error, so the cleanup label is never jumped onto. Therefore, it doesn't make any sense to have the parse_argv function return an integer value, if it effectively can return only value of zero.

[libvirt] Entering freeze for libvirt-1.2.7
by Daniel Veillard 03 Aug '14

03 Aug '14

It's that time for the month ! As planned I have tagged a first release candidate in git and sent tarbal and rpms to the usual place: ftp://libvirt.org/libvirt/ Seems to work for my limited testing but please give it a try, and let's fix the reported bugs ! I will try to put a release candidate 2 snapshot out on Wednesday and make the release on Friday, Daniel -- Daniel Veillard | Open Source and Standards, Red Hat veillard(a)redhat.com | libxml Gnome XML XSLT toolkit http://xmlsoft.org/ http://veillard.com/ | virtualization library http://libvirt.org/
