[libvirt] [PATCH] hostdev: fix net config restore error
by Huanle Han
Fix for such a case:
1. Domain A and B xml contain the same SRIOV net hostdev(<interface
type='hostdev' /> with same pci address).
2. virsh start A (Successfully, and configure the SRIOV net with
custom mac)
3. virsh start B (Fail because of the hostdev used by domain A or other
reason.)
In step 3, 'virHostdevNetConfigRestore' is called for the hostdev
which is still used by domain A. It makes the mac/vlan of the SRIOV net
change.
Code Change in this fix:
1. As the pci used by other domain have been removed from
'pcidevs' in previous loop, we only restore the nic config for
the hostdev still in 'pcidevs'(used by this domain)
2. wrap a function 'virHostdevIsPCINetDevice', which detect whether the
hostdev is a pci net device or not.
3. update the comments to make it more clear

[libvirt] [PATCH] tests: qemu: Couple aarch64 CPU tests
by Cole Robinson
- Make sure aarch64 host-passthrough works correctly
- Make sure libvirt doesn't choke on cpu model=host, which is what
virt-install/virt-manager were incorrectly specifying up until recently.

[libvirt] [PATCH v2 0/9] Additional host name check for network storage pools
by John Ferlan
v1 here:
http://www.redhat.com/archives/libvir-list/2015-April/msg00873.html
Essentially a rewrite of v1 changing to use virsocketaddr.* rather than
virutil.*
Also making check for hostname duplication prior to startPool rather
than during XML processing
John Ferlan (9):
socketaddr: Add isNumeric flag to virSocketAddrParseInternal
socketaddr: Introduce virSocketAddrParseName
iscsi: Check for validity of pool source hostname
netfs: Check for validity of pool source hostname
gluster: Check for validity of pool source hostname
sheepdog: Check for validity of pool source hostname
virsockaddr: Split up functionality of virSocketAddrFormatFull
virsocketaddr: Introduce virSocketAddrIsSameTCPHost

[libvirt] [PATCH 0/4] tests: Cleanups and improvements
by Cole Robinson
First 3 patches are uninteresting cleanups, removing a bunch of
boiler plate code.
The last patch adds a way to easily regenerate test output, like when
adding a new test case (plop in the qemu XML, use the env var and the test
suite will create foo.args for you), or when a code changes causes test
suite output to expectedly change.
Cole Robinson (4):
tests: Add VIR_TEST_DEBUG and VIR_TEST_VERBOSE
tests: Use *DefParseFile more
tests: Add virtTestCompareToFile
tests: Add VIR_TEST_REGENERATE_OUTPUT
