[libvirt] [PATCH] vircommand: fix polling in virCommandProcessIO
by Roman Bogorodskiy
When running on FreeBSD, there's a bug in virCommandProcessIO
polling that is triggered by the commandtest.
A test that triggers EPIPE in commandtest (named "test20") hungs
forever on FreeBSD.
Apparently, this happens because FreeBSD sets POLLHUP flag on revents
when stdin in closed. And as the current implementation only checks for
POLLOUT and POLLERR, it ends up looping forever inside
virCommandProcessIO and not trying to do one more write() that would
trigger EPIPE.
To fix that check for the POLLHUP flag along with POLLOUT and POLLERR.

[libvirt] [PATCHv2]rework the check for the numa cpus
by Luyao Huang
V1 discussion:
https://www.redhat.com/archives/libvir-list/2015-April/msg00919.html
new for v2:
remove 1/2 because no need introduce a new flag to avoid the broken
introduced by the new check.
We introduce a check for numa cpu total count in 5f7b71,
But seems this check cannot work well. There are some scenarioes:
1. one of cpu id is out of maxvcpus, can set success(cpu count = 5 < 10):
<vcpu placement='static'>10</vcpu>
<cell id='0' cpus='0-3,100' memory='512000' unit='KiB'/>
the cpus '100' exceed maxvcpus, this setting is not valid (although qemu
do not output error).
2. use the same cpu in 2 cell, can set success(cpu count = 8 < 10):
<vcpu placement='static'>10</vcpu>
<cell id='0' cpus='0-3' memory='512000' unit='KiB'/>
<cell id='1' cpus='0-3' memory='512000' unit='KiB'/>
I guess nobody will use this setting if he really want use numa in his
vm. (qemu not output error, but we can find some interesting things in
vm, all cpus have bind in one numa node)
3. use the same cpu in 2 cell, cannot set success(cpu count = 11 > 10):
<vcpu placement='static'>10</vcpu>
<cell id='0' cpus='0-6' memory='512000' unit='KiB'/>
<cell id='1' cpus='0-3' memory='512000' unit='KiB'/>
No need forbid this scenario if scenario 2 is a 'valid' setting.
However add new check during parse xml will make vm has broken settings
disappear after update libvirtd, so possible solutions:
1. add new check when parse xml, i chose this way in this version.
2. add new check when start vm.
I think this is a configuration issue, so no need report it so late.
3. just remove this check and do not add new check... :)

The virNetDev{Restore,Replace}MacAddress() functions are only used
by VF-related routines that are available on Linux only. So move these
functions under the same #ifdef.

[libvirt] [PATCHv2] qemu: Fix issues with maxMemory in qemuDomainSetMemoryFlags()
by Peter Krempa
From: Luyao Huang <lhuang(a)redhat.com>
qemuDomainSetMemoryFlags() would allow to set the initial memory greater
than the <maxMemory> field. While the configuration would not work as
memory hotplug requires NUMA to be enabled and the
qemuDomainSetMemoryFlags() API does not work on NUMA guests this just
fixes a corner case.
The fix is still worth though as it allows to induce an invalid
configuration and make the VM vanish on libvirt restart.
Additionally this tweaks error message to be more accurate.
