[libvirt] [PATCH] python: prefer PyList_SET_ITEM to PyList_SetItem
by Giuseppe Scrivano
The PyList_SET_ITEM macro, differently from PyList_SetItem, doesn't do
any error checking and overwrites anything that was previously stored
in the list at the chosen destination position.
PyList_SET_ITEM is usually faster than PyList_SetItem, and since it is
used only to fill freshly created lists, it is safe to be used here.

[libvirt] [PATCH] qemuMigrationBeginPhase: Check for 'drive-mirror' for NBD
by Michal Privoznik
So far we are checking if qemu supports 'nbd-server-start'. This,
however, makes no sense on the source as nbd-server-* is used on the
destination. On the source the 'drive-mirror' is used instead.

[libvirt] rpmbuild problem for 1.1.4
by Franky Van Liedekerke
Hi,
using the latest 1.1.4, I'm having issues to get the rpm build to
complete. I'm always getting this error:
==================
Wrote: /root/rpmbuild/RPMS/x86_64/libvirt-1.1.4-1.el6.x86_64.rpm
error: create archive failed on file

==================
Using 1.1.3-1 results in the same error, while 1.1.2 builds without
problems (all 3 tried today).
The command is just "rpmbuild -tb libvirt-xxx.tgz" on a patched CentOS
6 system.
I also did a diff on the favicon file and it is the same in 1.1.2 and
1.1.3-1.
Any hints on how the get the build to work on a CentOS 6 system? The
spec file has changed quite a bit between 1.1.2 and 1.1.3 ...

[libvirt] [PATCH] tests: Distribute virpcitestdata
by Michal Privoznik
Since 21685c955e5466 we have tests/virpcitestdata dir containing the PCI
config files for some dummy PCI devices that are used int virpcitest.
However, the directory containing the config files is not distributed
making 'make rpm' fail.

[libvirt] When vm's status file being left over, some persistent but inactive vms will be lost by libvirtd after libvirtd rebooting.
by Wangyufei (A)
Hello,
I found a problem that:
vm's status file may be left over in the path /var/run/libvirt/qemu under some situation, such as host reboot. When vm's status file is left over, some
persistent but inactive vms will be lost by libvirtd after it is rebooted. And you can do as follows to reproduce the problem:
1、Create a vm and start it by the commands: virsh define vm-xml and virsh start vm-name.
2、Stop the libvirtd by the command: service libvirtd stop.
3、Kill the qemu process related to the vm, and make the vm's status file left over.
4、Start libvirtd.
After starting the libvirtd service, we find that the vm has been lost by libvirtd with command"virsh list --all".
What we expect is that the vm is shown with shutoff status, should we?
The reason for the problem is that:
During libvirtd startup, it first loads status files of vms under the path /var/run/libvirt/qemu, creates virDomainObj for each vm and adds it to
driver->domains list.
Then it creates a thread to connect related qemu process for each virDomainObj in the domains list.Because the qemu process has been killed, so connecting to
qemu will be failed. When connecting to qemu failed, connection-thread will do the follows:
1、Check if vm->persistent is 1.
2、If vm->persistent is not 1, then qemuDomainRemoveInactive() is called to remove the virDomainObj.
3、Then the following calling sequence will occur:qemuDomainRemoveInactive() -->virDomainObjListRemove()-->virHashRemoveEntry(). Around virHashRemoveEntry(),
domlist and dom will be locked and unlocked sequencely.
The problem of the above steps is that vm->persistent maybe has been set to 1 by libvirtd main-thread when connection-thread calling virHashRemoveEntry() to
remove the dom. That is a persistent virDomainObj is removed during libvirtd startup.
Two ways can resolve the above problem:
1、expending the range of locking virDomainObj and virDomainObjList, lock the object of virDomainObj and virDomainObjList in connection-thread before checking vm->persistent.
2、checking vm->persistent again before calling virHashRemoveEntry().
Do you think it is a problem described above and which way listed above is more suitable to resolve the problem, or is there any other better idea? Any suggestions?
Best Regards,

[libvirt] [PATCH 0/3] more storage cleanups
by Eric Blake
I'm still plugging away at getting gluster backing chains to work;
here's a couple of independent cleanups that can be applied first.
Eric Blake (3):
storage: use simpler 'char *'
storage: avoid short reads while chasing backing chain
storage: reduce number of stat calls
