1. vm.destroy is not a mandatory step when dd_test is executed directly.
2. If dd_test is called as subtest in some other tests,
   caller's following steps may be interrupted
   for vm has been destroyed.

live_snapshot_chain: Flush data to disk before running system_reset

QMP command 'system_reset' is issued after creating files in the guest. The
command has an effect similar to the physical reset button on a PC. But
filesystems may be left in an unclean state which causes the loss of data. Run
the command "sync" to flush the data to disk.

iozone_windows: Delete "mem=2048" from iozone_windows.cfg

iozone_windows cfg set mem=2048 before, but when the guest
min memory large then 2G, like win2016 need min memory 4G,
the job will be canceled.
It's better that let the guest use automatic allocation mem value.

balloon_hotplug: invoke simple_hotplug() to set bus under q35

nic_hotplug: python3 compatible, add e1000e, remove e1000

Signed-off-by: NYanan Fu <yfu@redhat.com>

QEMU "info qtree" output depends on information generated by guest
firmware. One example is the bus number in PCI device address. QEMU
retrieves it from the PCI configuration space of the bridge which
creates the bus that a PCI device is attached to. So if test runs
"info qtree" before firmware finishes initializing pci devices, its
output can be incorrect.

The current code works around this timing issue by sleeping 5 seconds.
That is not reliable and doesn't work on my aarch64 system. So I'd
suggest to change the test to not start until it verifies the guest
has booted up. This will make the test execution time slightly longer
but is reliable.
