Currently enforce with cpumodel=host on amd cpus don't work,
because amd cpus have unsupported flags in qemu.
This is a protection, and this is good.
but cpumodel host should be never use by users for production (only for testing).
For production and stability, users need to choose a true cpu model which filter
the supported cpuflags by qemu.
So I think we can remove the enforce for host model as for testing it's ok.

rdtscp is not supported by qemu and with enforce it's not starting
warning: host doesn't support requested feature: CPUID.80000001H:EDX.rdtscp [bit 27]
from to qemu wiki
http://wiki.qemu.org/Features/CPUModels#Disabling_features_that_were_always_disabled_on_KVM
"Fact: currently libvirt runs CPU models having rdtscp without the "enforce" flag, and rdtscp is silently disabled
Consequence: libvirt SHOULD use something like "-cpu Opteron_G5,-rdtscp",
especially when it starts using (or emulating) enforce mode
This will require a solution on libvirt side. QEMU will just provide the mechanisms to report CPU model information
and check what the host and QEMU supports, but the decision to disable rdtscp to be able
to run Opteron_G[2345] needs to be taken by libvirt."

Currently backup don't work with iothread feature, and crash qemu
For now, abord the backup if one of the vm drives have iothread enabled until backup code is fixed.
Upstream qemu backup cde already support iothread.

Only non-cdrom drives default to cache=none, so the check
for whether to default to aio=native needs to take the same
condition into account.
I combined them close together to make their relation more
visible.
drive-mirror is doing lseek on source image before starting, and this can take a lot of time for big nfs volume
during this time, qmp socket is hanging
http://lists.nongnu.org/archive/html/qemu-devel/2015-05/msg01838.html
so we need to setup a big timeout
qemu devs are currently working to fix this

Since qemu 2.2, a new "ready" flag has been added to blockjob
http://git.qemu.org/?p=qemu.git;a=commit;h=ef6dbf1e46ebd1d41ab669df5bba0bbdec6bd374
to known if we can complete it.
we can't use len==offset to known if all block are mirrored, because behaviour will change soon in qemu 2.3

"block/mirror: Improve progress report
Instead of taking the total length of the block device as the block
job's length, use the number of dirty sectors. The progress is now the
number of sectors mirrored to the target block device. Note that this
may result in the job's length increasing during operation, which is
however in fact desirable.

netcat6 supports both ipv4 and ipv6, contrary to netcat-traditional.
Additionally rather than using the alternatives-managed /bin/nc path,
/bin/nc6 is now used which always points to the netcat6 implementation,
allowing us to drop the netcat-openbsd conflict entry.
It is better to check if a VM is running in QemuServer then in Storage.
for the Storage there is no difference if it is running or not.

Currently qemu auto fallback to aio=threads if cache=none|directsync
It's better to handle that correctly
see:
https://bugzilla.redhat.com/show_bug.cgi?id=1086704http://wiki.qemu.org/ChangeLog/2.3
Future incompatible changes:
Block device parameter aio=native has no effect without cache.direct=on. It will be made an error.
